The efficiency is kinda average, but the panels are cheap and quite sturdy, so i would say that they are worth their money.

Finally got a chance to check out American-made panels! They’re good, budget-friendly, but very powerful at the same time!

Yes. Mission Solar is the one the best US made panels on the market.
Is it American or Canadian? Where do they make them?

Mission Solar panels are made in Texas, USA.
Good day. What are the requirements for the installation?

Hello. If you mean solar permit, then the requirements differ from state to state. Consult with your installer, he should know all the details about getting the papers.
Will these panels work during a blackout?

It depends on your system type, but in the panels you use. Grid-tie solar systems shut down during power outages due to safety reasons. If you want to have interrupted power supply, you need to add energy storage to your installation or go off grid.
