We’ve purchased these panels for our car service in Texas. Since we’ve ordered over 60 modules, a1store made us a discount, plus the shipping was cheaper. The installation is going to take a while, but the package arrived safely and overall we are very happy with our purchase.

Glad that some American companies have finally stepped in and started making good solar panels.

Good day. If you want to purchase panels for your home, you need to find an installer and get a solar permit — that’s the policy of most states. Panels produce direct current on their own, so you would need an inverter to make AC for your household appliances.
Are those for commercial use? How many would i need for a shop?

These panels can be used both in residential and commercial systems. The number of panels depends on your energy needs – first you need to calculate them. Check out our guides, take a look at the solar calculator. Contact our staff if in doubt.
