(2) What is Solar Energy?
Solar energy is energy that people can obtain for free. The sun produces energy every single day that is completely wasted, but now it can be used. By using a solar system, people can make use of the energy that the sun produces on a day to day basis. One of the most popular ways is to use photovoltaic cells in solar panels, that eventually are converted using a converter, into electricity.
Solar energy capturing has been done for a number of years. Nowadays there are extremely effective ways to do this, although the best is using solar panels. The solar panels absorb the rays from the sun, which creates energy. This energy can be easily converted into electricity to power the home. The great thing is, if there is any left, the owner can sell the electricity units to a utility supplier.
The main advantage of using solar energy rather than conventional energy resources is that they produce free energy. Instead of spending hundreds every month, people can now produce their own electricity for free. In fact, they can actually make money if they have extra energy to sell to utility suppliers.
There are a few barriers that stop a lot of people using solar energy. One of the major disadvantages and barriers of using solar energy is the fact that the upfront cost is extremely high. In many cases, it will cost thousands to produce and install a solar energy producing system, which means that a lot of people simply can not afford it.
