A solar system is made up of connected solar panels that absorb rays from the sun and convert it to electricity.
The panels are made in such a way that when the sun rays come into contact with the surface of the panels, the solar cells convert them into DC (Direct Current) electricity. Since this form of electricity is not usable in most homes or businesses, an inverter transforms this direct current, into alternating current (AC). The AC electricity is now ready for use in our businesses or our homes.
The average life expectancy of most solar panels falls between 25 and 30 years. This is a long period that is great to cover the initial set up price. However, some other solar panels do have a shorter life span, while others have a longer one. For instance, the thin-film solar panels come with a lifespan of between 14 and 17 years. Other more expensive models can have a life expectancy that can go up to 50 years. Therefore, it all depends on the type of panel.
The solar panels start creating electricity immediately after installation. Therefore, you might even see the changes in the next bill you receive.
Studies have shown that homes with solar energy systems sell for more than homes without them. However, your property value will only increase if you own, rather than lease, your solar panel system. In most parts of the country, going solar will actually increase your property value more than a kitchen renovation.
Photovoltaic panels can use direct or indirect sunlight to generate power, though they are most effective in direct sunlight. Solar panels will still work even when the light is reflected or partially blocked by clouds. If you live in an area with a strong net metering policy, excess energy generated by your panels during sunny hours will offset energy that you use at night and other times when your system isn't operating at full capacity.
