At Clean Solar, we stand behind every system we install with one of the strongest production guarantees in the industry.
We guarantee that your solar system will produce the annual energy output stated in your contract. If it doesn’t, we’ll pay you the difference.
If your system produces less than the guaranteed annual energy (allowing a 4% margin for normal weather variation), Clean Solar will reimburse you based on the average price you paid your utility for electricity over the previous 12 months.
Many solar companies rely solely on manufacturer equipment warranties. Those warranties protect the equipment—but they don’t guarantee your system will actually produce the energy you were promised.
Clean Solar’s Production Guarantee is different.
Our production guarantee is 8% stronger than the California Solar Initiative (CSI) performance standard, giving homeowners an extra layer of confidence that their investment will perform as expected.
Simply put, we don’t just install solar—we guarantee the results.
After your system has been operating for one full year (365 days from permission to operate), we’ll compare its actual production to the guaranteed production listed in your contract.
If your system falls below the guaranteed amount (after the 4% weather allowance), we’ll verify the results within five business days and reimburse you for the difference. Payments are typically issued within 30 days.
That’s the Clean Solar difference: real accountability, real performance, and real peace of mind.
