I purchased these panels mainly because the warranty caught my eye. Never saw a 30 year performance warranty before and decided that these guys probably think highly of their product. Hope to live long enough to see these panels age.

Got the package, thanks! The installation started, everything goes as it should so far. My installer (a really nice guy) approved my choice and said that Silfab panels always pay for themselves and not just once here in California, but two or three times.

We (me and my wife) purchased these panels five months ago for our flower shop in Phoenix. Our electric bills diminished by, i’d say, 80%. Even though I had my doubts in the beginning, now I really know that it was a good decision to go solar. Thank you

Hi. I heard you need to get a permit to install solar. Will i need one for these panels?

Good day. Whether or not you need a permit depends not on the model, but on the state. In most states the permit is required, but it’s usually your installer who handles most of the work.
Hello. i live in montana, and it snows a lot here. will it affect them? how long are these going to last?

Good day. Silfab panels last at least 30 years. The cold won’t be an issue, they actually work better when it’s cold and sunny. However, if the snow is thick, you have to clean it to allow panels to produce energy in winter.
