Solar Energy is energy from the sun or known as radiant energy emitted by the sun. How is it produced? Solar power is arguably the cleanest, most reliable form of renewable energy available, and it can be used in several forms to help power your home or business. Solar-powered photovoltaic (PV) panels convert the sun’s rays into electricity by exciting electrons in silicon cells using the photons of light from the sun.
Solar energy is an alternative for fossil fuels as it is non-polluting, clean, reliable and renewable source of energy. It does not pollute the air by releasing harmful gases like carbon dioxide, nitrogen oxide or sulphur oxide. So, the risk of damage to the environment is reduced. Among all the benefits of solar panels, the most important thing is that solar energy is a truly renewable energy source.
Solar power disadvantages are actually not so plentiful. In fact, there’s only one notable disadvantage to solar power that I can think of. That disadvantage is that the sun doesn’t shine 24 hours in a day. When the sun goes down or is heavily shaded by clouds, solar PV panels stop producing electricity. If we need electricity at that time, we have to get it from some other source. In other words, we couldn’t be 100% powered by solar panels. At the very least, we need batteries to store electricity produced by solar panels for use sometime later.
It is the most important source of energy for life forms. It is a renewable source of energy unlike non- renewable sources such as fossil fuels. Solar energy technologies use the sun’s energy to light homes, produce hot water, heat homes as shown in solar tankless water heater reviews and electricity.
Solar power systems generate electricity at peak power usage times (during the day) when the value and cost of electricity is the highest. Modern grid-tied home solar power systems can use the cheap rate grid power at night and reduce or eliminate the need for the high rate electrical power during the day.
In Utah 98.2 percent of the energy produced in Utah is derived from oil, natural gas, and coal, but renewable energy resources are quickly expanding with an expected 850 megawatts of solar energy coming online by the end of 2016.
