Solar / renewable energy (PACE, PPA, solar loan)

Does your product fit here?

Solar and renewable energy financing spans multiple product types with very different credit characteristics. The core distinction: are you financing consumer purchases of residential solar systems, or commercial property improvements through PACE? The underwriting, pricing, and investor universe differ significantly across these categories.

Products that fit here:

Residential solar loans: Fixed-term consumer installment loans used to purchase rooftop solar systems. The loan is typically secured by a UCC-1 filing on the equipment. Mosaic, Goodleap (formerly Loanpal), Dividend Finance, and Sunlight Financial originate these. Monthly payments usually designed to be lower than the homeowner’s prior electric bill.
Solar leases: The originator (or tax equity partner) owns the equipment; the homeowner leases it. Lease payments are fixed or escalating. At lease end, the customer can purchase the system, renew, or have it removed. Sunrun is the dominant lease/PPA player.
Residential PPAs (power purchase agreements): Similar to leases, but the homeowner pays for electricity generated rather than equipment use. Rate is typically set below the local utility rate with annual escalators of 1-3%. Common in high-electricity-cost states (California, New York, Massachusetts).
C-PACE (Commercial Property Assessed Clean Energy): Financing for energy improvements on commercial properties, repaid through a special assessment on the property tax bill. The assessment creates a senior lien that runs with the property. Petros PACE, Nuveen Green Capital, and Counterpointe are active originators.
R-PACE (Residential PACE): The residential version of PACE, now largely dormant due to regulatory challenges. If you have legacy R-PACE exposure, see the dedicated section below.

What does NOT fit here:

Utility-scale solar / wind: These are project finance transactions, not asset-backed finance. A utility-scale solar farm has a single power purchase agreement with a utility or corporate offtaker. The credit is the offtake contract and project cash flows, not a pool of consumer obligations. See Infrastructure Debt for coverage of project finance.
Community solar: Typically project finance with subscription agreements. Credit depends on the project sponsor and offtaker structure, not pooled receivables.
Standalone battery storage: Emerging asset class with very limited securitization track record. Treated as equipment finance or project finance depending on scale.
EV charging infrastructure: Equipment finance or infrastructure debt, depending on the deployment model.

The core economics

For residential solar loans and leases, the underwriting thesis is straightforward: the customer’s solar payment should be less than their prior electricity bill. If a homeowner was paying $200/month to the utility and now pays $150/month on the solar loan, the economic incentive to pay is strong. When solar economics don’t pencil (system oversized, utility rates drop, net metering changes), delinquency risk increases.

For C-PACE, the credit is the property, not the obligor. The assessment attaches to the property tax bill and survives foreclosure. Capital providers treat C-PACE more like municipal bond credit than consumer receivables.

Market benchmarks and comps

Residential solar loan performance

Metric	Super-Prime (720+)	Prime (680-719)	Near-Prime (640-679)
CDR (annualized)	0.8-1.5%	1.5-3.0%	3.0-6.0%
CNL (lifetime, 15-20 yr term)	3-6%	6-12%	12-20%
CPR (annualized)	10-15%	12-18%	8-14%
Loss severity	40-55%	45-60%	50-65%
WAL	6-8 years	7-9 years	7-10 years

Unlike unsecured consumer loans where severity is 90%+, solar loans have meaningful recovery value. The equipment can be removed and resold, or the lien enforced through foreclosure. However, removal costs ($3,000-$8,000) and the illiquid secondary market for used systems limit recoveries. Budget 40-60% severity for your credit model.

Solar lease / PPA performance

Lease and PPA performance tends to be stronger than loan performance for the same FICO band because the payment is directly tied to the customer’s electricity savings. If the customer stops paying, they lose access to cheaper power.

Metric	Prime Lease/PPA	Near-Prime Lease/PPA
60+ DPD	1.5-2.5%	2.5-4.5%
Charge-off rate	0.8-1.8%	1.5-3.5%
Customer retention at lease end	85-95%	80-90%
Buyout rate	40-55%	35-50%

Residual value is the key risk for lease structures. At end of term (typically 20-25 years), the originator must either sell the system to the customer, redeploy it (expensive), or write it down. Conservative residual assumptions run 10-20% of original system cost; aggressive assumptions run 20-30%.

C-PACE performance

C-PACE has the best credit performance in the solar/renewable category because of tax lien priority.

Metric	C-PACE Benchmark
Default rate	0.5-1.5%
Recovery (post-default)	90-98%
CPR	5-8%
WAL	12-18 years

Prepayment is low because PACE assessments typically have prepayment restrictions or penalties, and the financing is property-specific. Defaults that do occur are usually cured through the property tax collection process or at property sale.

What “good” performance looks like

Residential solar loans:

Prime portfolio: CNL tracking below 4% at 36 months seasoning
CPR within 25% of base case assumptions
No material vintage-over-vintage deterioration
Geographic diversification (no state > 25%)

Solar lease/PPA:

60+ DPD below 2.5%
Customer retention at lease renewal above 85%
Residual realization at or above underwriting assumptions
Equipment degradation tracking manufacturer specs

C-PACE:

Default rate below 1.0%
No correlation with broader property tax delinquency in same jurisdictions
Assessment-to-value ratio remaining stable through term

Red flag benchmarks

Solar loan CDR exceeding 4% annualized for prime vintages
Solar lease 60+ DPD above 5%
C-PACE default rate above 2%
Any vintage with month 12 CDR more than 1.5x the prior vintage at the same point
Residual value realization below 50% of assumptions
System performance below 85% of projections after Year 3

What lenders and investors focus on

1. For residential solar loans: consumer credit plus system economics

Standard consumer credit metrics apply: FICO, DTI, and income verification. But solar loans add a layer that unsecured consumer credit doesn’t have: does the system make economic sense for this customer?

FICO distribution: Most solar loan originators target 680+ FICO. Near-prime (640-679) programs exist but carry meaningfully higher loss expectations. Below 640 is rare in solar lending due to the long loan terms (15-25 years).

DTI at origination: The loan payment should ideally offset an existing utility expense, so DTI may not increase post-funding. Capital providers look at whether the solar payment plus remaining utility costs exceeds the customer’s prior utility bill. If total energy expense increases, the loan is harder to underwrite.

Home equity: Solar borrowers own their homes (by definition, for rooftop systems). Homeownership is a credit positive, and customers with substantial home equity have lower default rates. Loan-to-value on the home (including all encumbrances) matters for recovery prospects.

System economics: Capital providers model the customer’s payback period. A customer in California paying $0.35/kWh with good solar exposure has better economics than a customer in Oregon paying $0.12/kWh. The system should produce savings from Year 1. If the customer needs to wait 8 years to break even, default risk increases.

2. For solar leases and ppas: residual value and customer retention

Residual value assumptions: At end of a 20-year lease, what is the system worth? Technology improves, so a 20-year-old system competes against newer, cheaper alternatives. Conservative capital providers stress residual to 10-15% of original cost; aggressive assumptions run 25-30%. Your underwriting should survive a 50% haircut to residual assumptions.

Customer buyout behavior: What percentage of customers purchase the system at lease end versus requesting removal? High buyout rates (50%+) reduce residual risk because the customer absorbs it. Track historical buyout rates and price sensitivity.

Equipment redeployment: If the customer doesn’t buy out and the system has value, can you redeploy it? Removal costs $5,000-$10,000, shipping and reinstallation add more. The secondary market for used panels is thin. Most originators write down redeployed systems to near-zero.

Customer creditworthiness evolution: A lease runs 20-25 years. The customer who signed at age 40 is 60-65 at lease end. Credit migration over that period is substantial. Model customer defaults through retirement transitions.

3. For c-PACE: property credit, not consumer credit

Property value and LTV: The key metric is total encumbrance on the property (mortgage + PACE + any other liens) relative to property value. Conservative programs cap total LTV at 80-90%. PACE assessments are senior to the mortgage, which creates complexity.

Assessment-to-value ratio: PACE assessments typically run 10-25% of property value. Higher ratios increase mortgage lender resistance and complicate property sales.

Underlying property cash flow: Is the property generating sufficient NOI to cover all obligations including the PACE payment? DSCR analysis matters even though PACE has tax lien priority.

Mortgage lender consent: PACE’s senior lien position creates tension with mortgage holders. Many programs now require or strongly encourage mortgage lender consent. Portfolios with high consent rates trade tighter.

State enabling legislation: PACE authority varies by state and municipality. Some programs are well-established (California, Florida); others are new or uncertain. Legislative or administrative changes can affect collection mechanisms.

4. Cross-cutting concerns for all solar products

Geographic concentration: State policy drives solar economics. Net metering rules, utility rate structures, and renewable portfolio standards vary dramatically. A portfolio concentrated in a single state faces policy risk if that state’s rules change. California’s transition from NEM 2.0 to NEM 3.0 (effective April 2023) reduced the economics for new solar installations significantly.

Installer concentration: Most solar originators work with dealer networks. If a single installer represents more than 15-20% of origination, that’s concentration risk. Installer quality varies, and a dealer with poor installation practices generates warranty claims and customer complaints.

Net metering policy: Net metering lets solar customers sell excess generation back to the grid at retail rates. States are moving toward less favorable policies (reduced compensation, demand charges, time-of-use rates). Model the impact on customer economics if net metering rules change during the loan term.

Equipment and warranty: Panel manufacturers provide 25-year warranties on output degradation (typically 80% of original output at year 25). Inverters have shorter lives (10-15 years). If the manufacturer fails mid-warranty, the customer may have a claim against an empty entity. Track manufacturer financial health and warranty claims history.

Typical structures used

Warehouse facility

The standard financing vehicle for growing solar originators.

Product	Advance Rate	Pricing	Notes
Residential solar loans	75-85%	SOFR + 200-350 bps	Higher advance for super-prime
Solar lease/PPA	65-80%	SOFR + 225-375 bps	Residual stress drives lower advance
C-PACE	80-90%	SOFR + 150-275 bps	Tax lien priority justifies higher advance

Illustrative pricing. See pricing disclaimer.

Revolving period is typically 18-24 months. Warehouse triggers include delinquency, default rate thresholds, and concentration limits (state, installer, system size).

Solar warehouses require attention to equipment lien perfection. The UCC-1 filing must be proper, and some lenders require fixture filings or property owner acknowledgments. Documentation complexity is higher than unsecured consumer lending.

Term ABS (144A)

Solar ABS is a well-established market with regular issuance from major originators.

Major issuers:

Mosaic (MSAIC): Residential solar loans, quarterly issuance, rated by KBRA
Sunnova (NOVA): Lease and loan portfolios, KBRA rated
Sunrun (RUN): Largest lease/PPA portfolio, Fitch and KBRA rated
Goodleap (formerly Loanpal): Residential loans, KBRA rated
Dividend Finance: Residential loans, KBRA rated

Typical deal size: $200M-$500M for solar loans; $300M-$750M for lease/PPA portfolios

Rating agency coverage: KBRA is the most active agency in solar ABS. S&P has rated select transactions; Fitch covers lease structures. Most solar ABS carries two ratings.

Enhancement levels: See Rating Agency Treatment section below.

Forward flow

Common for smaller or emerging solar originators not yet ready for term ABS.

Pricing: Yield-based. Capital providers target 10-14% net yield for prime solar loans, higher for near-prime or lease/PPA with residual risk.

Structure: Purchaser commits to buy loans meeting eligibility criteria on a flow basis. Volume commitments vary from $5M-$25M/month.

C-PACE securitization

C-PACE financing often uses municipal bond structures given the tax-assessment backing.

Tax-exempt structures: Some C-PACE programs issue through conduit issuers as tax-exempt municipal bonds. This reduces the cost of capital but limits the investor base.

Rated note structures: Taxable C-PACE securitizations are rated by S&P, KBRA, or Fitch. Enhancement levels are lower than solar loans due to tax lien priority.

Active issuers: Petros PACE Finance has completed multiple rated securitizations. Nuveen Green Capital (via Greenworks Lending acquisition) is a major originator.

Tax equity interaction

Solar economics depend heavily on federal tax credits. The Investment Tax Credit (ITC) provides a 30% credit for residential solar (extended and enhanced under the Inflation Reduction Act of 2022). Commercial solar can access either ITC or Production Tax Credit (PTC).

Tax equity structures: Originators without sufficient tax liability partner with tax equity investors (banks, insurance companies, tech companies) to monetize credits. Common structures include partnership flips and inverted leases.

Debt subordination: When tax equity is present, debt providers are typically subordinate to tax equity economic distributions during the credit period (usually 5-7 years). After the “flip,” the originator may have the option to buy out tax equity.

ITC recapture risk: If the system is removed or the property sold within 5 years, a portion of the ITC is recaptured. This creates a structural incentive against early default.

Asset-class-specific structural features

Residential solar loans

Equipment lien: Solar loans are secured by a UCC-1 filing on the equipment. Unlike a home mortgage, this doesn’t give the lender an interest in the real property, only the solar system. Some lenders also file a fixture filing to address equipment that becomes attached to the property.

Dealer recourse: Originators that work through dealer networks may negotiate dealer recourse provisions. If a loan defaults within 12-24 months, the dealer may be required to repurchase or cover losses up to a cap. Dealer recourse shifts early-onset risk but concentrates credit risk on the dealer.

Repayment term: Solar loan terms run 10-25 years, much longer than typical consumer installment paper. This creates unique duration risk, customer life-stage risk, and technology obsolescence risk.

System performance guarantees: Some originators guarantee minimum system output. If generation falls below thresholds, the originator credits the customer’s loan payment. These guarantees reduce customer default risk but create originator liability.

Prepayment: Solar loans typically have no prepayment penalty. CPR runs 10-18% annually, driven by home sales, refinancing, and system buyouts. Model both extension (low CPR) and prepayment (high CPR) scenarios.

Solar lease / PPA

Residual value allocation: At lease end, who bears the risk that the system is worth less than projected? In most structures, the originator (or their successor) bears residual risk. Capital providers stress residual aggressively when sizing facilities.

Customer buyout options: Leases typically include fair market value buyout options at end of term, with periodic buyout windows during the term. Buyout pricing affects customer behavior and residual realization.

Escalator clauses: PPA rates often escalate 1-3% annually. Escalators that outpace utility rate increases erode customer economics over time, increasing late-term default risk.

Equipment removal: If the customer declines to purchase or renew, the originator must remove the system. Removal and site restoration costs $5,000-$10,000. This cost is often not fully reserved in early lease structures.

Redeployment provisions: Can the removed system be reinstalled elsewhere? Older systems have limited redeployment value, and logistics costs often exceed system value.

C-PACE structural features

Tax lien priority: PACE assessments are collected with property taxes and have the same priority. In foreclosure, PACE is paid before the mortgage. This priority drives favorable credit performance but creates tension with mortgage lenders.

Property assessment mechanics: PACE is structured as a special assessment against the property, not a loan to the property owner. The obligation runs with the property and transfers on sale.

Term matching: PACE terms (typically 15-25 years) are designed to match the useful life of the improvement. Prepayment is often restricted or penalized.

Consent requirements: To address mortgage lender concerns, many programs require or encourage lender consent before recording PACE assessments. High-consent portfolios trade tighter.

Improvement verification: PACE programs require third-party verification that the improvement was installed and meets program requirements. Energy savings projections must be documented.

Rating agency treatment

KBRA

KBRA is the most active agency in solar ABS, rating the majority of solar loan and lease securitizations.

Methodology focus:

Static pool and vintage performance data (minimum 24 months preferred)
Installer/dealer concentration analysis
Geographic distribution and policy risk
Originator financial health and servicing capability
For leases: residual value stress testing

Stress multiples: Base case losses derived from vintage data, with AAA stress multiples of 3.0-4.5x depending on asset quality and originator track record.

Residual assumptions (leases): KBRA applies significant haircuts to residual value, often stressing to 25-50% of the originator’s base case.

S&P

S&P has limited but growing coverage in solar ABS.

Approach:

Conservative loss assumptions based on limited performance history
Emphasis on originator-level risks given the relatively young asset class
Cross-sector comparison to auto and consumer ABS
Servicer continuity analysis

Fitch

Fitch is active in solar lease/PPA structures.

Focus areas:

Equipment value and residual risk
Customer credit quality migration over long lease terms
Servicer assessment
Geographic and installer concentration

Typical credit enhancement levels

Rating	Solar Loan	Solar Lease/PPA	C-PACE
AAA/Aaa	14-20%	20-30%	8-14%
AA/Aa2	10-15%	15-22%	6-10%
A/A2	7-11%	10-16%	4-7%
BBB/Baa2	4-7%	6-10%	2-4%

Solar lease/PPA requires higher enhancement due to residual value risk. C-PACE requires lower enhancement due to tax lien priority.

Key rating considerations

Installer concentration: Agencies typically require no single installer above 15-20% of the pool. Higher concentration results in additional subordination.

Geographic concentration: Pools concentrated in a single state (especially California given policy changes) face additional stress.

Originator track record: New originators face higher enhancement requirements until they establish 36+ months of performance data.

Residual stress (leases): Rating agencies may assume 50-70% haircut to originator residual projections for AAA stress scenarios.

Diligence focus areas

Tape analytics

Required fields:

Loan: origination date, funded amount, interest rate, term, remaining term, payment, FICO, DTI, state, installer, system size (kW), equipment manufacturer, utility, net metering status, lien filing date
Lease/PPA: contract start date, monthly payment, escalator, term, system size, residual assumption, customer FICO, state, installer, equipment manufacturer

Standard stratifications:

FICO bands (640-679, 680-719, 720-759, 760+)
State distribution
Installer distribution
System size bands
Origination vintage
Loan term distribution

Key analytics:

Vintage loss curves by FICO band
CPR by rate environment and FICO
System performance vs. projections by geography
Customer complaint and warranty claim rates by installer

Installer / dealer diligence

Capital providers spend significant time on dealer network quality. A poorly installed system creates customer complaints, warranty claims, and defaults.

Diligence items:

Installer licensing and certifications
Installation quality audits (sample basis)
Warranty claims history
Customer satisfaction scores (NPS, BBB complaints)
Dealer financial condition (for recourse programs)
Concentration limits in the facility

Common findings:

Installation defects in 3-8% of systems (roof penetration, wiring, panel mounting)
Warranty claims rates of 2-5% within first 2 years
Customer complaint rates correlated with specific dealers

System performance data

For lease/PPA structures, ongoing generation data validates residual value assumptions.

What to review:

Monthly generation data vs. projections by vintage and geography
Degradation curves vs. manufacturer specifications
Inverter failure rates and replacement timing
O&M expense trends

Benchmark: Systems should generate 90-95% of projections after accounting for weather normalization. Generation below 85% of projections is a flag.

State and regulatory diligence

Net metering status: Review the current net metering rules in top-5 concentration states. Identify pending regulatory proceedings that could change compensation rates.

Rate structures: Understand how utility rates have trended and what future rate cases may impact customer economics.

PACE program status: For C-PACE, verify the enabling legislation, program administrator, and any recent changes to program rules.

Tax credit status: Confirm ITC/PTC eligibility and any placed-in-service documentation requirements.

Servicer and collections

Site visit scope: Collections infrastructure, customer service operations, payment processing, equipment monitoring systems.

Key metrics: Contact rate, promise-to-pay conversion, time-to-charge-off, recovery rates on charged-off accounts.

Transfer readiness: Given long asset terms, backup servicer arrangements are important. Assess whether the backup servicer has solar-specific experience.

Red flags and off-market characteristics

Performance red flags

CDR exceeding 4% for prime solar loans: Base case for prime (680-719) should be 1.5-3.0%. Significantly higher default rates signal underwriting or customer economics issues.
Lease residual realization below 50% of projections: If early lease maturities show residuals coming in far below assumptions, the rest of the portfolio is at risk.
Geographic concentration above 30% single state: State policy changes (net metering, rate structures) can materially impact economics. California concentration is particularly concerning post-NEM 3.0.
Installer concentration above 20%: Single dealer dependency creates operational and credit risk.
System performance below 85% of projections: Indicates installation quality issues, equipment problems, or overly aggressive projection methodology.

Originator red flags

Rapid volume growth without infrastructure scaling: Solar originators that double volume year-over-year often face servicing capacity constraints and dealer quality degradation.
High customer complaint volumes: Check CFPB complaint database, BBB ratings, and state AG complaints. Solar has attracted regulatory scrutiny.
Dealer/installer disputes: Payment disputes with dealers signal cash flow stress or business model problems.
Working capital deterioration: Solar originators often have negative working capital during growth phases. Watch for signs of liquidity stress.
Key person departures: Credit officer or chief risk officer departures without prompt replacement.

Structural red flags

Subordination to tax equity without clear flip mechanics: If debt is subordinate to tax equity distributions, understand the flip timing and conditions. Unclear structures create payment uncertainty.
No dealer recourse on high-volume dealers: For dealer-originated portfolios, some recourse (even capped) provides loss absorption for early-onset defaults.
Weak equipment lien perfection: UCC filings must be properly completed. Review a sample of filings for accuracy and completeness.
Inadequate removal reserves: Lease structures should reserve for system removal costs at end of term. Insufficient reserves create end-of-life cash flow problems.

Regulatory red flags

R-PACE exposure: Residential PACE has faced significant regulatory challenges (see dedicated section below). Legacy R-PACE portfolios carry headline risk and potential enforcement exposure.
Net metering policy changes pending: If major concentration states have regulatory proceedings that could reduce net metering compensation, model the impact.
ITC step-down not incorporated: The ITC is scheduled to step down over time (though extended under IRA). Ensure underwriting reflects current credit levels.
State licensing gaps: Solar installers and originators must be licensed. Check for any licensing deficiencies or enforcement actions.

Market red flags

Dealer fee compression: Healthy dealer economics support installation quality. If dealer fees are being squeezed, installation quality may suffer.
Customer acquisition cost escalation: Rising CAC without corresponding improvement in portfolio quality signals market saturation or competitive pressure.
Utility rate deflation: Solar economics depend on rising utility rates. If utility rates flatten or decline, customer economics deteriorate.
Technology disruption: Battery storage, community solar, and other alternatives may reduce demand for rooftop solar loans. Monitor market evolution.

Important: The combination of rapid origination growth + installer concentration + geographic concentration is the pattern that precedes credit deterioration in solar. When you see all three together, expect vintage performance to weaken.

R-PACE: the regulatory cautionary tale

What is r-PACE?

Residential PACE (Property Assessed Clean Energy) allowed homeowners to finance energy improvements through an assessment on their property tax bill. The assessment created a lien senior to the mortgage that transferred with the property.

The appeal: Low upfront cost to homeowners, long terms matching improvement life, repayment through familiar property tax collection.

Why it failed

R-PACE became a regulatory target due to consumer protection concerns:

Ability-to-repay issues: Unlike traditional mortgage lending, R-PACE programs did not uniformly verify borrower ability to repay. Some programs used property equity alone without regard to income or existing obligations. The CFPB and state regulators determined this exposed vulnerable homeowners to unaffordable obligations.

Senior lien problems: When R-PACE assessments are senior to the mortgage, they complicate refinancing and home sales. Mortgage lenders raised concerns about impaired collateral. FHA and VA prohibited FHA/VA-insured loans on properties with R-PACE assessments.

Enforcement actions: The CFPB brought actions against major R-PACE originators including Renovate America and Ygrene. California passed AB 1284, which imposed ability-to-repay requirements and gave the Department of Financial Protection and Innovation oversight.

Program restrictions: California, the largest R-PACE market, significantly restricted new R-PACE origination. Other states followed with limitations.

Current market status

Very limited new origination: Most major R-PACE programs have wound down or ceased new origination
Legacy portfolios in runoff: Existing R-PACE assessments remain outstanding but are not being securitized
Capital provider avoidance: Mainstream capital providers will not provide warehouse or term financing for R-PACE
Ongoing regulatory risk: Legacy portfolios face continued regulatory scrutiny and potential enforcement

Recommendation: Do not pursue R-PACE financing. If you have legacy R-PACE exposure, work with counsel to assess regulatory risk and consider accelerating runoff.

Utility-scale solar: why it’s not ABF

Utility-scale solar (solar farms selling power to utilities or corporate offtakers) is project finance, not asset-backed finance. Here’s why the distinction matters:

Single-asset exposure: A utility-scale project is one asset with one power purchase agreement. There’s no diversification across obligors. Credit depends on the offtaker (utility or corporation) and project execution.

Construction and completion risk: Utility-scale projects involve construction risk until commercial operation. ABF finances performing receivables, not construction.

Tax equity dominance: Utility-scale projects are typically financed 40-60% with tax equity. Debt is subordinate to tax equity distributions during the credit period.

Project finance economics: Returns on utility-scale solar are driven by capacity factors, curtailment, merchant exposure, and long-term power prices. This is infrastructure investing, not receivables financing.

Where to learn more: See Infrastructure Debt for project finance structures. Utility-scale solar is a well-established project finance asset class with different risk factors and investor universe.

Key terms and concepts

ITC (Investment Tax Credit): Federal tax credit equal to 30% of solar system cost for residential and commercial projects (as of IRA 2022). Historically the primary federal incentive for solar adoption.

PTC (Production Tax Credit): Alternative to ITC for commercial projects, provides per-kWh credit for electricity generated over 10 years.

Net metering: Policy allowing solar customers to sell excess generation back to the grid, typically at retail electricity rates. Critical to solar economics.

NEM 3.0: California’s updated net metering policy (effective April 2023), which significantly reduced compensation for exported solar generation. Reduced economics for new solar installations.

Partnership flip: Tax equity structure where the tax investor holds majority economic interest during the credit period (typically 5-7 years), then “flips” to minority interest after tax benefits are exhausted.

Inverted lease: Tax equity structure where the tax investor leases the system from the project company, claims ITC, and pays rent that approximates the ITC benefit.

C-PACE: Commercial Property Assessed Clean Energy. Assessment-backed financing for commercial property energy improvements.

Residual value: The projected value of leased equipment at end of lease term. Key driver of lease economics and credit enhancement requirements.
