Solar electricity makes great financial sense — offering an internal rate of return of as much as 15%. Solar installations have become more affordable with the help of a 30% government tax benefit, and homeowners can achieve energy independence and protect themselves from the rapidly escalating PG&E rates. With solar panels' long lifespan, you can enjoy sustainable energy for decades, contributing to a greener future. The average solar PV residential system (based on 5kW), will save nearly 132 tons of carbon dioxide over its 40-year lifespan.
