There are many choices when it comes to choosing a solar panel company. For example, you can opt for one that offers a 25-year warranty, such as SunPower. Sunrun also offers price-match and loans. These companies are not the only ones that offer solar panels. You can also order them from other online retailers.
SunPower offers 25-year warranties
SunPower, a San Jose California manufacturer of solar panel, is now offering a warranty on all new solar panels bought in the U.S. According to the company, the warranty will cover power and product performance for 25 more years than is industry norm.

This warranty is much more extensive than other solar panel warranties but there are still some caveats.

Green Power Technology provides loans
A solar-panel loan is a great option to finance your purchase. The loan can either be used as an individual loan or combined with other financing sources such a mortgage or personal loan. The amount of the loan and repayment period will depend on your personal financial situation, credit profile, and income. The maximum term of loans is 30 years.
