For most people, solar energy brings a lot of questions. In this blog, we will cover some of those frequently asked questions, as they apply to solar panel installation. Solar technology has developed a lot recently, providing us with longer lasting and more efficient panels. Find out below how those panels work, which ones to buy, and how long you can expect them to last.
What Part Do The Panels Play In A Solar System?
The panels are the big structures you see on people’s roofs. They are made out of silicon because nothing catches rays like silicon does. The panels catch the sun, they send it to the inverter, and the inverter switches it into AC (alternating current), which means electricity for your house.
How Do I Know What Kind Of Panels To Buy?
Ideally, the solar company you go with will put you in touch with the best panels for your house. Be on the lookout for panels that have long warranties (25 years), and are known for weathering warmer climates.
Is A Roof System My Only Option?
The other option is a ground system. In a more spacious setting like Northern California, you may have the yard for a ground set up. The amount of sunlight your roof gets plays a huge factor. If your roof doesn't get a lot of sunlight, a ground system may be the best option for you.
What Condition Must My Roof Be In To Install A Solar Panel?
Nowadays, solar systems come with 25 year warranties. If your roof is in need of repair now, or even a couple years from now, it’d be good to consider repairing or replacing before your system goes up. As for whether or not your roof needs replacing or just repair, this would be something a roofer could tell you with a quick look. Save yourself money in the process by consulting a roofing professional and getting his advice on it. Solar has been around for long enough now, that he will have seen and worked with solar systems and will know what he’s talking about.
How Long Will Solar Panels Last Once They’re Installed?
Today’s systems come with a 25 year warranty, and they're proven to lose little efficiency from years 25-35 (less than 10% deficiency). This gives most people an energy structure that will typically last past their time in the house.
Can I get a quote?
Yes. You can set up an appointment and have a solar professional look at your roof and give you an estimate. The size of your system will be forecasted depending on your previous twelve months of energy consumption. You will want to have your last twelve months of utility bills ready so that you get the system that's both the right size and right price for you. If the system is too small, it won't garner the energy you need, and you'll end up tapping into the grid more than you'd like. This is where you trust a local solar company to size the system you need, because, once it's up on the roof, it's up on the roof.
Hopefully this covered most of your big questions about solar panel installation. By signing up with a trusted solar company, you’ll be able to trust the process, and that the best system is being put in at your place.
