Solar Financing in California: Choosing Between Loans, Leases, and PPAs

Navigating Solar Financing in California

Transitioning to solar power in California is a major financial decision. With high utility rates from providers like PG&E, SCE, and SDG&E, homeowners are increasingly turning to solar to lock in lower costs. However, the path to ownership is paved with various financial models. At Apollo Solar Program, we want to ensure you understand your options so you can choose the path that best fits your household budget.

Understanding the Three Core Models

1. Solar Loans: The Path to Ownership

Solar loans allow you to purchase your system while spreading the cost over 5 to 20 years. In California, this is often the most popular choice because it allows you to capitalize on the federal Investment Tax Credit (ITC) and local incentives.

• Pros: You own the system, which increases home value. You are eligible for the 30% federal tax credit and any applicable local rebates.
• Cons: You are responsible for maintenance and repairs, though most modern systems include comprehensive 25-year warranties.
• Best for: Homeowners who plan to stay in their homes long-term and want to maximize long-term savings.

2. Solar Leases: Simplifying the Switch

In a lease, a third-party provider installs and owns the equipment on your roof. You pay a fixed monthly fee to 'rent' the equipment, regardless of how much energy the panels produce.

• Pros: Lower upfront costs and minimal maintenance responsibility. Your contract usually covers repairs and system monitoring.
• Cons: You do not receive the federal tax credits, and the system does not add the same equity to your home compared to ownership.
• Best for: Homeowners who want a predictable monthly bill and low upfront costs without the administrative burden of tax credits.

3. Power Purchase Agreements (PPA): Paying for Output

A PPA is similar to a lease, but instead of a fixed monthly fee, you agree to purchase the electricity produced by the panels at a set rate, usually lower than your utility’s current rate.

• Pros: No upfront investment. You only pay for the energy you generate, often at a discount compared to utility grid rates.
• Cons: These contracts can be long (20-25 years) and may complicate selling your home later if the new owner does not want to assume the PPA contract.

California-Specific Factors to Consider

The Impact of NEM 3.0

California’s current net metering policy, NEM 3.0, has changed how homeowners are credited for excess energy exported to the grid. Because the export rates are lower than retail electricity rates, battery storage has become an essential component for maximizing ROI. When choosing a financing model, factor in the cost of a home battery (like the Tesla Powerwall or Enphase IQ Battery). Loans often provide the most flexibility for adding battery storage to your system.

Tax Credits and Incentives

Remember that the 30% Federal Investment Tax Credit is only available to those who own their systems (via cash purchase or loan). If you choose a lease or PPA, the financing company takes the tax credit, which is how they are able to offer lower monthly payments.

Practical Tips for Your Solar Journey

1. Request Multiple Quotes: Never accept the first offer. Compare apples to apples by looking at the 'cost per watt' rather than just the monthly payment.
2. Review the Escalator Clause: If you choose a PPA or lease, check for an 'escalator clause,' which increases your monthly payment by a certain percentage each year. Aim for a fixed rate if possible.
3. Check Your Roof: Before signing any long-term financial agreement, ensure your roof is in good condition. You don't want to deal with a solar removal and re-installation just three years after going solar.
4. Use Our Calculator: Before committing to a contract, use our free solar savings calculator to estimate your real-world savings based on your specific utility provider and local sunlight exposure.

Conclusion: Which is Right for You?

Choosing the right financing is all about your personal goals. Do you want to own your equipment and maximize tax benefits? A loan is likely the best path. Do you prefer a 'hands-off' approach with no maintenance stress? A lease or PPA might be more appealing. There is no one-size-fits-all solution, but by comparing your options, you can ensure you’re making a smart investment for your home and the planet.
