An Example of a House Running on Photovoltaic Energy
Electricity, however it is generated, is expensive. You have to pay bills for all the power you consume. Though the world has moved to cleaner sources of electricity, it is still costly and there is a lot of infrastructure involved to bring electricity to your home.
Photovoltaic Energy or solar electricity is free as the source of power is the sun. However, photovoltaic panels are expensive to install, though the power will be free. It is still a green and renewable source of power. Few people, particularly in remote areas, have installed PV panels to generate electricity.
It is especially good as a back-up system for televisions, lighting in mobile homes and nautical uses. PV cells are used in smaller items like calculators, watches, chargers, ipods, burglar alarm systems, parking meters and more. As a green source of energy it has great future potential and for the environmentally friendly consumer, it is a viable option.
