Before We Go
In nearly all cases, the best residential solar panels are made with premium monocrystalline solar cells, and the same goes for solar panels listed in this post.
Monocrystalline cells are developed with a single crystal of silicon instead of melting together many silicon fragments (as done in the case with polycrystalline cells).
It means monocrystalline cells are more efficient when it comes to converting sunlight into electricity. On top of it, these cells look appealing as well.
The solar panels brands mentioned in this write-up have a proven track record of quality, durability, long warranty, and customer satisfaction. These are the characteristics that consumers and solar installers seek in solar panels for installation.
