What our happy customers say
I am new to using solar and had a great experience with A1Solar. I ordered 6 pcs of Q Cells 400W solar panels from them and delivery was fast / customer service was great! I look forward to buying from them again in the future.

I have ordered 2 solar panels from A1solarstore on pickup, but had some problems paying at the checkout. However, finally it went well.

Ordered panels for my house due to the nice pricing, came at super good quality. Definitely glad I picked here. (For those wondering I ordered 16pcs of Aptos Solar 370W!)

I was new to the Solar Panel Industry, just browsing for information when I came across A1 SolarStore. After doing researching and educating myself on products through their easy to navigate website I made my first purchase. I couldn't be happier by choosing to go through A1. The customer service I received was very beneficial on choosing Suntech 370 W Solar Panel. Best part of A1 is that the pickup locations was extremely convenient only miles from my home.

If you are looking to purchase Solar Panels, I would highly recommend A1 Solar store. I did not have much knowledge on Solar Panels and/or the benefits of them. A1 SolarStore customer service and knowledge of their panels was outstanding. My purchase of the Silfab 400W panels was made easy and quick with a pick up location right in my area.

I recently ordered a 8 piece of Aptos Solar 370W Solar Panels from A1 Solar Store. Everything was great from start to finish. Their website's easy navigation allowed me to compare different panels and view my options. The pick up location was extremely convenient and located close to my home. Overall very impressed with A1 SolarStore and product purchased. I highly recommend it for anyone in the market for Solar Panels.
