Solar
There are generally two ways solar is used to provide useful energy. Solar electricity or photovoltaic's (PV) can be used by anyone with a need for electric power. Solar heating collectors absorb the sun's energy and produce heat. These systems heat a fluid, either air or liquid. This fluid then is used to heat directly or indirectly indoor spaces, water for household use, swimming pools, or to make electricity. The use of solar heating or thermal systems is growing in Idaho but is still not widespread even though they are usually cost effective.
The largest use of solar energy in Idaho is solar electricity, particularly to provide electricity in remote locations. In locations where extending a power line to a site can be prohibitively expensive, a PV system is often the least cost solution. There are hundreds of such installations throughout Idaho providing electricity to homes, ranches, farms, and many other facilities that are not served by electric utility power lines. Idahoans can use PV power in any number of ways. All around Idaho PV systems are providing power for remote-facility electrification, lighting, communications, monitoring, warning signs, water pumping and cathodic protection. People using PV are the biggest supporters and the best sales people for this technology.
In recent years, the number of solar electric homes connected to the local utility grid has increased dramatically. These "grid-connected" buildings have solar electric panels or "modules" that provide some of their power, while still being connected to the local utility. Grid-connected systems generally use a billing process called "net metering". Please read "Net Metering in Idaho" for more information. In this process, any energy generated by the solar modules that the home or business does not use immediately is sent to the utility grid. However, when the solar electric system is producing less power than is needed, you can draw additional power from the grid. If your system is connected to the grid through a single electric meter, your meter can actually run backwards as you contribute excess energy to the utility.
The most important step in purchasing any solar system is choosing a provider with experience. A good provider will also have a properly licensed electrical contractor, have enough experience to have demonstrated an ability to work with customers and be able to compete effectively with other firms. A good provider should be familiar with the local utility's regulations on interconnection requirements. Please read "What to Expect from a Solar Dealer" for more information.
The Idaho Governor's Office of Energy Resources Solar Program offers assistance to Idaho citizens and companies interested in taking advantage of solar technologies for space and water heating, power generation, and more. Information on low interest loans is also available through the Idaho Governor's Office of Energy Resources.
