Solar is Money in Your Pocket

Solar is the best investment you can make in this economy. Purchase of a solar electric system should be viewed as an investment in your future, just like a bond or CD, only better. As quoted in Business Week “Solar Return on Investment (ROI) is 10 to 15%, while S&P 500 is 9.59%, a 30-year Treasury Bond is just 3.63% and a 5-Year CD is only 2.82%”! In other words Solar ROI is 5% more than any other investment right now and the payback period is just a few years, once the “payback period” is over solar electricity virtually eliminates your power bill therefore making you immune to the ever increasing costs of energy.

California Solar Systems provides turnkey solar services, this means we do all the work for you. With our in-house rebate and permit department we administer all of the paperwork for your project and handle all inspections. Our engineers will design the most cost effective solar solution that fits your specific energy needs so you only get the power you need. We will not over sell you. our goal is to save you money while reducing your impact on the environment.

We have offices in and service Northern and Southern California.

Our Products and Warranty

PRODUCTS - Our solar panels deliver up to 50% more power per unit than conventional solar panels. We use proven materials that are high quality, with all stainless steel racking equipment our systems exceed code requirements and in most cases we do not drill through your tile.

The panels are designed for use in on-grid residential and commercial systems. A reduced voltage-temperature coefficient, exceptional low-light performance and high sensitivity to light means maximum energy harvested year round.  Solar panel systems have no moving parts therefore there is little to no maintenance or up keep and offer decades of high energy production.

WARRANTY - Our systems have a 25-year power warranty along with a 10-year parts and labor warranty. We are a Premier Dealer so the labor warranty covers our installation for 10 years. No other solar panel company offers a warranty over 5 years for their systems nor does their warranty cover the installation.  Our in house installation teams are the best in the business and having gone through SunPower’s Premier Training Program makes them even better.

Our license is #920108, we began as Tower Construction 15 years ago turning our main focus to solar in 2007.

We are a Premier Dealer for SunPower Corporation, our main manufacturer. A Premier Dealer is the highest ranking you can achieve with SunPower, it involves many hours of specialized training and random installation audits from SunPower to maintain our Premier status.

We are a member of Solar Energy Industries Association (SEIA) which was established in 1974 and the Better Business Bureau with an "A" rating.
