Solar energy can be transformed into electricity. This potential is more and more being realized by home owners wanting to decrease carbon emissions and assist a more sustainable environment. Households are installing home solar electricity with battery backup systems to generate home power.

Household solar electricity systems can be designed to include a series of batteries to store electricity as backup. The battery bank stores excess electricity that is used by the household at some later time.

Soar home power systems usually connect into the electricity grid. Grid connection provides the home with additional backup and allows it to sell any excess electricity it generates into the grid.

The energy capacity of a battery is commonly expressed as ampere hours. For example, a single deep cycle battery may be rated at 140 ampere hours. To calculate the amount of electricity can be drawn from this battery when fully charged, it is convenient to convert ampere hours to watt hours. This is achieved by multiplying ampere hours by the voltage required by the appliances. For example, the 140 ampere hour battery will supply 140 x 110 equals 15,400 watt hours.

Photovoltaic systems installed on home rooftops typically have a generating capacity ranging up to 10 kilowatts (KW). For example, a 10 KW system can flow 10,000 watts of power at any one time, enough to illuminate 100 light bulbs each rated 100W.

A home solar electricity with battery backup system normally has four components. To begin, a solar panel system that generates electricity and supplies any excess to the battery bank. Next, the battery bank into which power is stored. Thirdly, an inverter that converts the power stored in the battery bank to 240V 0r 110 V or whatever is required by the household. Last, flip over switch that switches the electricity flow from the household inverter supply to the public grid supply, as required.
