Energy cannot be created or destroyed, but it can be saved in various forms. One way to store it is in the form of chemical energy in a battery. When connected in a circuit, energy stored in the battery is released to produce electricity.
Solar energy is a good alternative to replace fossil fuel as the major energy source because solar power is renewable at absolutely no cost to supply energy infinitely. … Solar panels are able to harness the energy from the sun and convert it to electricity. Therefore, the use of solar panels is environment friendly.
A typical house wastes 30 percent more energy than an efficient one does. On average, that means that 51 MMBtu’s are being wasted by a typical home every year. A typical home energy retrofit costs around $10,000 per house — before any utility or governments energy rebates are applied.
Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise many, smaller units called photovoltaic cells. … Many cells linked together make up a solar panel.
