Solar power is one of the most cost-effective alternative energy sources available today. Its energy source is free and is shining everywhere on the planet. The technology has also seen developments that made it possible to produce affordable solar panels. For this reason, many people in California have purchased solar panels and have installed them for home use. They have seen some drastic changes to their electricity usage and bills when they started using solar power, saving them a lot of money in the process. Now that the law requiring new buildings to have solar powers has been approved, new advances in solar tech are expected like increased efficiency and a decrease in price, increasing the demand for solar power.
Now imagine you are building a new house and need a solar array installed. You hired pros to do it but you are aware that they might make a mistake. The first thing that you should know is that solar panels should always be installed on the side of the roof facing the equator. In North America, this side faces south. In South America and Australia, this faces north. This is because the plane where the planets travel around the sun, hence where the sun also seems to travel around the planets, is within 23 degrees of the equator, making it the direction to face when you need maximum solar output. Of course, you can use roofs facing east or west, but never use the side facing north. You would get the minimum of solar output that way.
The second thing to consider is the tilt of the panels. You need to have the right angle to catch the sun’s rays. This angle depends on several factors including elevation, obstructions, and latitude. Latitude is very important because it determines the sun’s zenith at different points every year. You will need to tilt the panels to face the point in the sky where the sun is at its zenith the longest, giving it the most potential to catch solar radiation.
Now that the installation is finished, you are probably thinking that’s it. You’re done. You don’t need any upkeep activities. Wrong. You will need to make sure that dust and other debris do not accumulate to the point that efficiency has drastically dropped off. That means you will need to wipe the panels when you see there is a film of dust obscuring it, or there are leaves or snow on the surface. Even a small covered area can affect electricity generation.
It is very important to remember to use devices that consume the most electricity in the daytime, particularly at or around noon when the sun’s output is peaking. This would help you maximize your usage of solar panel-generated electricity, reducing your consumption of grid electricity. Also, it pays to have an energy-storage device for use when the grid is down. Contrary to popular belief, solar panels don’t work when there is a blackout as it is connected to the grid.
