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 Illinois solar energy contractor. You can find more solar energy contractors in Saint Louis, St Louis, Florissant, Granite City and Upper Alton.

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 Alton, IL 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 Illinois solar energy contractors and any necessary specialty subcontractors here on Houzz.
