There is no more straightforward way to define solar energy as the energy coming from the sun. The sun is a natural source of energy. It releases photons that can be converted into electrical energy by using elaborate devices. According to some studies, the amount of energy coming from the sun is so intense that it can power the entire world’s demand with just an hour’s worth of photons. However, this is not yet a reality. The technology to fully harness the sun’s energy has not been perfected. The good news is that scientific development and research are always being conducted to further the advancement of this endeavor. The day will come when solar energy would probably be the biggest source of our energy needs.
How do we harness solar energy?
Solar energy can be collected through the use of solar panels. These panels are usually placed in areas where sunlight will most likely hit. Take note: it does not necessarily mean that the solar panels will not collect solar energy when the sun is not shining intensely.
What are solar panels?
Solar panels are made up of many solar cells. Each solar is made of silicon. Each cell has two layers – one positive and one negative. These two layers create an electric field. As soon as photons hit a solar cell, electrons are knocked free from atoms generating a flow of electrical current. The current passes through the circuit. It gets converted to functional current.
Here’s a step by step process on how solar panels work:
- Sunlight hits the panels installed.
- The panels convert the solar energy received to a DC.
- The current flows to an inverter, which then converts the DC to AC.
- AC is the one that you can utilize to power your home.
How much solar energy can your panels generate?
If accurately measured and installed, solar panels can power your household’s regular demand for electricity. Most solar panels are designed to become a full substitute for the traditional energy source. However, there are some concerns from other potential consumers that solar energy may not be enough for their needs due to various reasons. One reason is that they live in a place where it is cloudy most of the time. Another reason is that they have a lot of appliances to power.
These concerns are understandable, but they can be very easily addressed. Solar panels work even on cloudy days. Just because the sun is not scorching hot one day means that you will have to spend the evening the lights off. Solar panels can store power. Further, solar energy is still available even on a cloudy day! Next is their concern about consumption. Solar panel companies will conduct an inventory of your electrical needs before installing the panels. They will assess how many panels you need in relation to your actual electrical demand.
