25 Year Production Guarantee
Merica Solar Panels offers a unique solar production guarantee – on TOP of your system’s standard warranty! If your system produces less power than we say it will, you can get a check for the difference covered under our 25-year production guarantee. That’s more power in your hands. When we say “freedom from high utility bills” we mean it!
How can Merica Solar Panels guarantee energy production?
It comes down to quality, and standing by what we promise. In order to be the best, we use the highest quality components, installed by experienced professional installers. Each solar system is meticulously inspected by a Merica Solar Panels professional after installation, as well as a local or city Inspector before the utility officials assess and grant permission to turn on your system. Once your system is on, it is monitored 24 hours a day, 7 days a week. If it ever breaks, we’ll make it right. We’ll even reimburse you for any energy production lost from our fault!*
*subject to terms and conditions of your agreement


How long do solar panels last?
Typically solar panels are warrantied to last 25 years, but many last a lot longer than that. In fact, there are first-generation solar panels still producing 75% of their original output after 40 years. The longer your panels last, the greater your return on investment. Luckily, Merica Solar Panels installs high quality solar panels built to last and we have a 25-Year Production Guarantee to prove it!

Step-by-Step Guide to Choosing Residential and Commercial Solar Panels in Oakland, CA
1. **Assess Your Energy Needs**
– **Residential**: Calculate your household’s average electricity usage in kilowatt-hours (kWh) per month by reviewing utility bills.
– **Commercial**: For businesses, evaluate energy needs based on operational hours, equipment usage, and peak electricity demand.
2. **Evaluate Roof or Ground Space**
– **Residential**: Measure your roof’s surface area to determine the available space for solar panels.
– **Commercial**: If space is limited on the roof, consider ground-mounted systems or large roof spaces to accommodate higher energy demands.
3. **Check Local Solar Incentives**
– Investigate solar tax credits, rebates, or incentive programs available in Oakland and statewide in California. These can include federal Investment Tax Credit (ITC) and state incentives.
– For businesses, inquire about commercial energy grants or utility rebates to reduce installation costs.
4. **Research Solar Panel Types**
– **Monocrystalline Panels**: Known for high efficiency and durability, they are ideal for smaller spaces.
– **Polycrystalline Panels**: Less expensive but slightly less efficient, suitable if space is not an issue.
– **Thin-Film Panels**: Best for commercial setups that require flexible installation options, though less efficient.
5. **Compare Efficiency and Durability**
– Look for panels with high efficiency rates (18% or higher) to maximize energy production, especially important for commercial buildings with limited space.
– Check the panel’s degradation rate to understand how well they’ll perform over time (lower degradation rates mean longer-lasting panels).
6. **Check Warranties**
– Residential panels should have at least a 25-year warranty.
– Commercial-grade panels may offer performance warranties up to 30 years, depending on the manufacturer.
7. **Find a Reputable Installer**
– Look for solar installers with positive reviews, strong credentials, and expertise in both residential and commercial systems.
– Verify that the installer is licensed and certified to work in Oakland, CA.
8. **Understand Financing Options**
– **Residential**: Consider options such as solar loans, leases, or power purchase agreements (PPAs) to minimize upfront costs.
– **Commercial**: Explore financing options like commercial loans, tax equity financing, or PPAs for businesses looking to offset energy costs.
9. **Request Multiple Quotes**
– Get quotes from at least three local solar companies to compare pricing, system designs, and services.
– Ask for a breakdown of installation costs, equipment, and potential savings over time.
10. **Review Maintenance Requirements**
– Ask about maintenance needs, such as cleaning or inspections, to ensure long-term performance.
– For commercial setups, consider investing in monitoring systems that track energy production in real-time.
11. **Analyze the Return on Investment (ROI)**
– Calculate the payback period based on expected energy savings, initial costs, and incentives. Most residential systems offer ROI within 6-10 years, while commercial systems may take slightly longer due to size.
12. **Check for Permits and Regulations**
– Ensure your solar installer handles all necessary permits and follows Oakland’s local building codes and zoning regulations.
By following these steps, you’ll be able to make a well-informed decision when choosing the right solar panels for your residential or commercial property in Oakland, CA.
