We will modify existing lighting applications as well as make energy-efficient upgrades to your existing property. We can change any light bulb in any light fixture. Sometimes old ballasts go bad and need to be replaced for new electronic and higher-efficiency equipment, we can supply and install all of these items.



With continually increasing power costs and the availability of cost-effective equipment combined with government incentives, now is definitely the time to go green. The federal government is encouraging homeowners to make the switch with a solar tax credit of 26% this year. In California, Title 24 now demands all new construction to meet the Building Energy Efficiency Standards requiring solar panels to be installed.

Solar is a great option if you are environmentally conscious and ready to stop depending on power utility companies that are repeatedly raising their rates. Solar increases the value and marketability of your home. There are many financing options available to meet your needs and the potential for almost no upfront costs.


Esquared Electric offers a wide variety of solar equipment and programs to accommodate you. We treat each homeowner as an individual and customize each solar project to optimize your needs. E2 partners with the top solar providers in the nation to get you the best deal possible. Our technicians are highly knowledgeable about renewable energy and happy to give you as much information as possible to help you make an informed decision.

In addition to home solar systems, we offer full off-grid generator systems and battery backups so your residence can be completely self-reliant. Esquared Electric also offers maintenance and troubleshooting services on existing solar projects. We work for you and with you.
