Sunrun provides several service models. The most common are solar leases, power purchase agreements (PPAs), and system purchases. With a solar lease, customers pay a monthly fee to use solar panels installed on their roof. A PPA is similar, but customers pay for the electricity the panels generate rather than paying to lease the equipment. Customers can also purchase solar systems outright, either paying cash upfront or financing the purchase through loans.

The company handles the installation process, which typically involves roof assessment, panel placement, electrical connections, and permitting. Sunrun also provides monitoring services that track how much electricity the system produces. The company maintains the panels and handles repairs if equipment fails during the contract period.

As of 2024, Sunrun operates in approximately 24 states plus Washington D.C., serving over 4.5 million customers. The company's service areas include California, Texas, Florida, and the Northeast, though availability varies by specific zip code and property characteristics.

Practical Takeaway: Before exploring Sunrun services further, homeowners should understand which service model (lease, PPA, or purchase) aligns with their financial situation and long-term plans for their property.

How Solar Panel Installation Works

The solar installation process involves multiple steps that span several weeks from initial contact to system activation. Learning how this process works helps homeowners understand the timeline and what happens at each stage.

The first step is a property assessment. A Sunrun representative visits the home to evaluate roof condition, sun exposure, shading from trees or buildings, and electrical infrastructure. This assessment determines whether the property is suitable for solar installation and how many panels would fit. The company uses satellite imagery and on-site measurements to calculate potential energy production. This assessment is typically free and carries no obligation.

After assessment, Sunrun provides a customized proposal showing estimated monthly savings, system size, and costs under the customer's chosen service model. The proposal includes information about incentives like the federal Investment Tax Credit (ITC), which currently allows homeowners to deduct 30% of solar installation costs from their federal taxes (though this percentage decreases in future years).

Once a customer agrees to the proposal, Sunrun handles the permitting process with local authorities. This involves submitting technical drawings, structural plans, and electrical specifications to city and county departments. Permitting timelines vary but typically take 2-8 weeks depending on local requirements.

Installation typically takes 1-3 days. Sunrun workers install racking systems to mount panels on the roof, connect electrical wiring, and install the inverter (equipment that converts solar power to usable household electricity). After installation, local inspectors must approve the system before it can operate.

Practical Takeaway: The complete process from initial assessment to full operation usually takes 2-4 months, so homeowners should plan accordingly and understand that multiple inspections occur before the system generates power.

Understanding Costs and Financial Models

Solar costs vary significantly based on system size, location, and the service model chosen. Understanding the financial differences between leasing, PPAs, and purchases helps homeowners make informed decisions about which option works for their situation.

With a solar lease, customers typically pay between $100-$250 monthly, depending on system size and location. There is usually no upfront cost (though some companies charge small documentation fees). The customer does not own the equipment, so they have no responsibility for repairs during the lease term, which typically lasts 20-25 years. However, customers do not receive tax credits, as Sunrun owns the system and claims those benefits.

A Power Purchase Agreement (PPA) requires no upfront cost either. Instead of a fixed monthly fee, customers pay only for the electricity their system generates, typically at a rate slightly below local utility prices. This rate often increases by 2-3% annually. PPAs also last 20-25 years, and the company maintains the system.

Purchasing a system requires significant upfront investment, typically $15,000-$25,000 after federal tax credits, depending on system size. However, customers own the equipment and receive the 30% federal tax credit (as of 2024). They may also claim state or local incentives. Purchased systems can generate savings of $10,000-$30,000 over 25 years, depending on local electricity rates. Some customers finance purchases through loans, spreading payments over 5-10 years while the system produces power immediately.

Additional financial considerations include net metering policies, which vary by state. Net metering allows customers with solar systems to receive credits for excess electricity they feed back to the power grid. These credits offset electricity costs when the system underproduces (during cloudy weather or at night).

Practical Takeaway: Customers should compare the three service models using their own electricity bills and local rates. Lease and PPA options require less financial risk upfront, while purchase options offer greater long-term savings but require larger initial investment.

Maintenance, Monitoring, and System Performance

Solar panels require minimal maintenance, but understanding what upkeep involves helps homeowners have realistic expectations about owning or leasing a system. Monitoring technology allows customers to track their system's performance over time.

Modern solar panels are designed to last 25-30 years with minimal degradation. They typically lose about 0.5% of efficiency per year, meaning a system producing 100% of expected power in year one would produce approximately 87.5% by year 25. This gradual decline is normal and expected.

Physical maintenance involves occasional cleaning, especially in dusty climates or areas with significant pollen. Dust, dirt, and bird droppings can reduce efficiency by 5-25% depending on accumulation. In most regions, regular rain provides sufficient cleaning. Some customers use soft brushes or hire professionals for periodic cleaning, typically 1-2 times yearly in arid regions and less frequently elsewhere. Cleaning costs typically range from $150-$300 per visit.

Inverters, which convert solar power to household electricity, typically last 10-15 years and may need replacement during a system's 25-year lifespan. Replacement costs range from $2,000-$4,000. For leased or PPA systems, Sunrun covers inverter replacement as part of the service agreement. System owners must budget for this replacement themselves or purchase extended warranties.

Monitoring systems track real-time electricity production and alert customers to performance issues. Most Sunrun customers access a mobile app or website showing daily, monthly, and annual production data. This monitoring helps identify problems quickly. For example, if production suddenly drops 20% on a clear day, the system may have a wiring issue or inverter malfunction requiring service.

Weather events like hail can damage panels, though modern panels resist damage from typical hailstones. Leased and PPA systems typically include insurance coverage for weather damage. System owners should verify their homeowners insurance covers solar panels or purchase additional coverage.

Practical Takeaway: Leased and PPA systems require minimal customer responsibility for maintenance, as Sunrun handles repairs and monitoring. Customers who purchase systems should budget for occasional cleaning and potential inverter replacement mid-life.

Tax Credits, Incentives, and Financial Considerations

Multiple federal, state, and local incentive programs can significantly reduce solar system costs. Understanding which incentives apply to different service models helps customers evaluate their true financial benefit.

The federal Investment Tax Credit (ITC) is the most substantial incentive. As of 2024, customers who purchase solar systems can deduct 30% of installation costs from their federal income taxes. This percentage was scheduled to decrease over time, declining to 26% in 2025 and 22% in 2026, though Congress could extend it. For example, a $20,000 system would generate a $6,000 tax credit at current rates. Only system owners claim this credit; lease and PPA customers cannot, as Sunrun owns the equipment and claims the credit instead.

Many states offer additional incentives beyond the federal credit. California provides rebates for some
