Our Services & Solutions
Solar plus Energy Storage
Under California’s NEM 3.0 program, pairing solar with battery storage is more valuable than ever. With reduced export rates for excess solar energy sent to the grid, homeowners benefit most by storing and using their solar power when it’s needed most. A battery system helps you maximize your savings, reduce reliance on the utility, and protect against power outages. Plus, with smart energy management, you can optimize when to use stored energy and when to pull from the grid, ensuring you get the most out of your solar investment.

About
Client Feedback
Michael L., Escondido
My experience with CleanTech Energy was by far the best from researching to vetting to installation including interviewing previous customers. Very neat and clean installation . We had our system installed in September of 2022 and activated in October of 22. CleanTech had no shortage of satisfied customers to speak with during the vetting process which ran contrary to one of the larger and older companies who advertise heavily on television during the time I was taking bids. They could only provide me with one reference! Astounding for a company that’s been in business for more than 80 years. I heartily recommend CleanTech Home Energy Solutions.
Rich F., Escondido
Stop looking, Clean Tech is the answer to all your solar needs. They actually do what they say they will do! Our Solar journey started in April 2023 with an dishonest solar company. They left us high and dry with equip-ment up but not connected or permitted - a nightmare! For over a year we looked to find someone to take on our project and got a "no" after "no", nobody wanted to help us. I checked SDGE website, looked for approved Solar installers and found CLEANTECH ENERGY SOLUTIONS. From the first meeting they inspired confidence and honesty. They explained things in easy to understand language, are extremely knowledgeable, very easy to work with, honest and upfront. I can't say enough about them - Thank you so much!
Terry A., Vista
We chose CleanTech for several reasons. First, their solution was the one that most closely fit our energy needs. Second, they listened to what we were asking for, answered questions, and demonstrated a sincere willingness to go above and beyond to help us. Third, we wanted to deal with a local company, if possible. Because they are located in our area, they were the obvious choice. They weren't the cheapest, but based on our selection criteria, they were the best. Later, when we ran into problems because SDG&E no longer could get the equipment we needed, they reworked the plan to accommodate a different option. We're extremely pleased with their work.
