What Types of Energy Systems Do Solar Energy Contractors Install?


The most common types of alternative energy systems for the home are solar electric, solar water heating and wind power systems. Solar professionals can help with everything from replacing old skylights with new solar skylights to installing complete solar energy systems.

Let’s say you want a solar electric system for your home. An off-grid system basically consists of solar panels and battery banks. These battery banks store the sun’s energy so you can use electricity at night or on a cloudy day. This system is designed to keep household electricity running for about two or three cloudy days; longer cloudy periods require a backup generator. To install an off-grid system, you’ll want to hire a certified California solar energy contractor.

Along with off-grid solar, wind and hybrid energy systems that include batteries and backup generators, there are also grid-tied solar and wind operations. Grid-tied systems are attached to your Portola Valley, CA utility company so if you produce more energy than you use, your meter goes down and you build up energy credits.

Installing solar skylights can save electricity. Sun tunnel skylights are tubular daylight devices that capture sunlight through domes on your roof. Attached to these domes are highly reflective tunnels that draw natural light down into closets, hallways and stairways.

Solar energy can heat your home, produce electricity and provide hot water. Solar power systems are part of the growing trend toward energy sustainability. Whether you are aiming for increased sustainability or want to improve energy conservation, you’ll find California solar energy contractors and any necessary specialty subcontractors here on Houzz.

Questions to ask potential solar energy contractors:


  • Do you have state certification?
  • Will you come to my home for a free onsite consultation?
  • Are you able to repair an older system?
  • Can you provide me with a layout to see where the panels will go and what they will look like?
  • Can you give me any information on solar rebate programs?
