About us

NextEnergy was founded in 1976 by Randy Kauffman to focus on high quality installations of Solar Photovoltaic (PV) systems. Originally a division of Accurate Heating & Cooling (CA Lic # 194796), NextEnergy is dedicated to three core principles in solar applications… Performance, Reliability, Longevity.

We custom engineer and install each system to exceed industry performance expectations. Our solar electric systems routinely out-perform California Energy Commission (CEC) performance expectations by up to 25%. Bottomline, our customers get more power from their NextEnergy system than they would have had someone else installed their array.

Our “Marine Grade” installation means we only use the highest quality materials for every customer. From racking holding panels in place to the bolts attaching the system to the structure, and everything in between, we never compromise quality! We NEVER subcontract our installation. Each of our lead installers is a seasoned professional with hundreds of installations under their belt, which means each of our installations meets meticulous standards to provide years of worry free electricity.

By using the best materials, having highly trained, skilled and experienced installations crews, and custom engineering each system, we provide our customers systems that will last longer than systems installed by other companies. We are one of the rare solar energy companies with a Class A Engineering license in addition to our General Building license (CA Lic # 854338 AB). This allows us to put together solar energy solutions we know have the longevity our clients demand.
