What Happens When a Solar Installation Has No Clear Performance Agreement

Solar installation contracts involve significant upfront costs, 25-year warranties, and complex interconnection agreements with utilities. Vague performance guarantees are among the most common solar disputes.

What's at Stake

Vague production guarantees in solar contracts are frequently litigated. Homeowners who receive significantly less electricity than projected may have fraud and misrepresentation claims if the estimates were inflated without disclosed assumptions.

What Happens If This Goes Wrong

Solar panel agreements that do not address roof warranty implications may void the home's roof warranty when panels are installed. Missing performance monitoring provisions mean underperformance may go undiscovered for years.

Critical Deadlines

Cooling-off period: consumers have the right to cancel most home improvement contracts (including solar) within 3 business days under FTC rules. Interconnection applications can take 2–12 months depending on utility. Equipment warranties should be transferred to future homeowners upon property sale.

A solar energy agreement governs the installation, monitoring, and performance of a photovoltaic (PV) system. It should address roof warranty implications, production guarantees, monitoring obligations, equipment warranties, interconnection timelines, and what happens if production falls below projections.

Solar Agreement Terms

Property Address *

The address where solar equipment will be installed. Solar incentives, net metering policies, and utility interconnection rules are all location-specific.

Agreement Type * Outright Purchase Power Purchase Agreement (PPA) Solar Lease Solar Loan / Financed Purchase

A PPA means you buy the electricity produced, not the equipment. A lease means you pay a fixed monthly fee. Purchase or loan means you own the system and keep all incentives.

System Size (kW DC)

The direct current (DC) nameplate capacity of the system. Average U.S. residential systems are 6–12 kW. Annual production should be estimated for your specific location.

PPA Rate ($/kWh) or Monthly Lease Payment ($)

PPA rates are typically 10–20% below your utility rate. Lease payments are fixed monthly. Both should be compared against your current and projected utility costs.

Annual Rate Escalator (%)

Many PPAs and leases include an annual price escalator (1–3%). This increases your payments each year. Compare the escalator to historical utility rate increases in your area.

Agreement Term (Years) 20 years 25 years 10 years (loan/purchase) Custom term (specified)

PPA and lease agreements typically run 20–25 years. These agreements transfer to new owners when a home is sold — disclose to potential buyers as required.

Federal & State Incentive Ownership Customer retains all tax incentives (purchase/loan) Provider retains tax incentives (PPA/lease)

The 2026 federal Investment Tax Credit (ITC) is 30% of system cost. Only the system owner can claim it. In a PPA/lease, the provider owns the system and keeps the ITC.

Frequently Asked Questions

Common questions about Solar Energy Agreement

What is a solar performance guarantee?

A performance guarantee is a commitment from the solar installer that the system will produce a minimum amount of electricity (measured in kWh) per year. If production falls below the guaranteed level, the installer owes you compensation (typically a check for the value of the electricity shortfall at your current utility rate). Demand specific numbers — vague guarantees like "optimized production" are unenforceable.

Who owns the solar panels — homeowner or solar company?

Depends on your agreement: (1) Cash purchase: you own the panels outright from day one. (2) Solar loan: you own the panels but owe the lender. (3) Solar lease: the solar company owns the panels, you pay monthly to use them. (4) Power Purchase Agreement (PPA): the solar company owns the panels, you buy the electricity they produce at a per-kWh rate. Leases and PPAs can complicate home sales.

What happens to my solar panels when I sell my house?

Owned systems: they increase home value and transfer to the buyer. Leased systems: the buyer must either assume the lease (qualify for approval) or the lease must be paid off before closing. PPAs: similar to leases. Many buyers are reluctant to assume solar leases and PPAs. Some sellers have lost deals or taken price reductions because of solar financing obligations. Consider cash purchase or solar loans over leases.

How long do solar panels last?

Most solar panels are warrantied for 25 years for at least 80% of original production output. In practice, panels last 30–40+ years with reduced output. Inverters typically last 10–25 years and need replacement during the system lifespan. Batteries (if installed) last 10–15 years. The financial model for most solar projects assumes a 25-year payback calculation — verify this matches your specific system warranty.

What is net metering and how does it affect my agreement?

Net metering allows homeowners with solar to sell excess electricity back to the utility grid, receiving credits on their bill. Net metering policies vary by state and utility — some offer full retail credit, others a lower rate. Your solar production estimate should be based on the current net metering policy in your area. If net metering rules change (increasingly common), your payback period and financial return could change significantly.
