One of the simplest solutions to reducing the dependence of electricity on national grid energy is to switch to renewable energy resources. The most viable and easily available renewable sources of energy are solar and wind energy. Solar and wind energy can be easily harnessed with the help of solar panels and windmills to give you stand-alone sustainability.

Time variation affects the potential of solar energy because, during the night, there is little solar radiation on the surface of the earth for solar panels to absorb. This limits the amount of energy that solar panels can absorb in one day. Solar feeds your energy banks with daylight sun sources while the wind turbine continues throughout the night, so there is no loss of enhancing and charging your energy banks, making you totally stand alone.
