What Are The Different Parts of a Solar PV System?
If you’ve been thinking about installing solar panels in Tampa, for your home or business, you’ve most likely been picturing something like this:
Well yes, that’s what solar panels look like on your home! But there’s more to a solar power system than solar panels. Even in the above picture, you’ll notice the difference in the two solar panels is more than just their color. If you want to install solar panels on your property, it’s important to understand the different parts of a solar panel system.
At Expert Solar, we believe that going solar is an important decision and a great investment. That’s why we value education. Your understanding of the different parts of a solar PV system is just as important to us as it is to you, the home or business owner.
Fortunately, even though the thought of going solar may seem daunting at first, we’re happy to let you know that a basic understanding the different parts of a solar system can be achieved in less than 15 minutes. No, we’re not trying to rush you through this but a solar panel system isn’t actually very complicated because solar panels have no moving parts.
Unlike a car’s engine, that is made up of hundreds of different parts that move together and respectively effect one another, a solar system has only has FOUR MAIN PARTS. None of them have machinery or moving pieces and they all work together to supply your home with clean, affordable and sustainable energy!
Understanding a Solar PV System in 15 Minutes
There it is, a solar PV system and all it’s four parts. At the bottom of the article you will find links to more details about each individual part but here is a quick explanation of each, since after all we did promise you would understand the basics of a system in 15 minutes:
SOLAR PANELS: The solar panels use the sun’s photons and through very conductive materials turn the suns energy into direct current.
As a fun fact, the energy from sunlight that reaches Earth is roughly 4% UV rays, 43% visible light, and 53% infrared rays. Solar panels convert a lot of the visible light into electrical energy, and they can make use of almost half the infrared energy. Solar panels only use a small portion of UV rays.
INVERTERS: Because your house uses AC (alertnating current) and not DC (direct current) a solar PV system needs inverters that take the direct current and turn it into alternating current so that your home can use the energy created by the solar panels. The inverters you choose for your system are very important so be sure to read the additional information provided about inverters in the below link.
RACKING (AKA: MOUNTING): Racking or mounting is the actual rig that the solar panels are attached to on your roof. Essentially a frame that ensures the solar panels are sturdily attached to your roof and facing at the right angle for optimal energy production.
BATTERY: Solar batteries are used for two purposes. The primary purpose is to store energy created by your solar panels so that you have energy available at night when solar panels are not producing power. But don’t worry, if you don’t have a battery as part of your solar PV system, you will definitely still have power at night. The other purpose is to help you maintain power throughout power outages in the grid. Batteries are optional. For that reason, we do not generally include them in a solar installation unless specifically requested by you or unless we see the need for them when designing your system.
Well, there you have it! All four parts of a solar PV system explained in under 15 minutes.
I hope that this information is helpful for you when you are considering going solar.
