Customer Reviews for NextEnergy
Ratings & Reviews
Read all of NextEnergy's Google reviews hereI purchased a SunPower PV system from Next Energy in 2009. 15 years later it is still going strong. The output has decayed over time, but not as much as the initial predictions, which is great. I have had no issues with the panels, the installation, or the core functions of the inverter. I think Next Energy made a good choice by installing the inverter in a relatively protected location that has prolonged its life. I recently consulted with Next Energy about some minor issues on the inverter and they provided helpful advice. It is important to choose a solar installer that will be around for a long time because you may need support many years after installing a system. Next Energy has longevity that I value.
NextEnergy cut our electric bills with excellent solar solutions. Their 20+ years of experience showed in the smooth installation. We’ve saved money and reduced our carbon footprint. Highly recommend NextEnergy for solar.
Farzad Samari was fantastic, a real pleasure to work with, very knowledgeable. The solar panels that were installed are high-grade and function extremely well. Farzad helped me communicate with PG&E about my NEM status and with his guidance that worked out positively. Farzad coordinated well with the roofer, with whom he had never worked before. He also made sure that I got the tax filings correct concerning the rebates . I couldn’t have asked for a better partner in the project.
