Solar panel systems, also known as photovoltaic (PV) systems, use solar cells to convert sunlight into electricity. Solar cells are made up of semiconductor material, usually silicon, which absorbs the energy from the sun's rays and converts it into direct current (DC) electricity. This DC electricity then passes through an inverter, which changes it to alternating current (AC) electricity, which is the type of electricity used in homes and businesses. The AC electricity then travels to an electrical panel, where it can be used to power lights, appliances, and other electrical devices. Any excess electricity produced can be stored in batteries or sent back to the electric company for a credit on your electric bill.
Solar panel prices vary considerably depending on the solar energy company and installation equipment you choose. While cheap solar energy looks good at first, it is more profitable to invest in quality equipment to keep your overall savings high over the long term. You can also review the current solar energy incentives and discounts in your area, thereby, reducing your net cost by around %50.
The size of solar system you install depends on your roof top size or overall property size, your electricity needs and consumption and your budget. Interestingly, your home size does not actually determine the amount of solar panels you need; a bigger home does not equal more energy consumption.
Yes, they do. Solar panels generate electricity from the sun’s light, not the sun’s heat. On the other hand, the performance in winter is lower because panels will receive less light due to shorter winter days but this does not prevent your savings.
