Residential Solar Power Systems
With the rising cost of fuel and the issue on global warming, cheap, efficient and environmentally-friendly power production are the orders of the day. Right now, scientists are hard at work in trying to find alternative means of energy that will end our dependence on fossil fuels.
One such alternative being proposed is the use of solar power. It is an option which harnesses the energy from the sun to generate power.
The benefits of solar energy have already been recognized by the ancient Greeks, Native Americans and the Chinese. It is only now, however, that people are trying to get the most out of this energy source.Probably the most common method of harnessing solar energy is through the use of the so-called photovoltaic effect. This is done by using a solar cell which absorbs the light from the sun and converts it to electricity.
When used in homes, a PV system is installed to the roof of the house to absorb as much as solar energy as it can. And since the energy generated is direct current (DC), it couldn’t be used by appliances which use alternating current (AC). The energy should therefore be converted from DC to AC using an inverter.In order to make the most use of the energy absorbed by the PV system, it should be stored in batteries so that the power could be utilized even at night or during cloudy weather.
While using solar energy is an ideal way of generating electricity, it has yet to come into the mainstream because of several factors. On top of the list is the price. It isn’t cheap to build a solar home because the materials are expensive at this point. Unless they can be produced cheaply, solar energy may not take off as an alternative source of power.
