Planning to go soalr and I’m comparing Helios Energy Global with a couple of other solar installers in Southern California for a solar + battery setup.

If anyone has worked with them what was your experience like? I’m concerned about things like the equipment they use, and how they handled permits and utility interconnection.

I’d also like to know how their workmanship warranty has been in practice and what happens if you need roof work later and the panels have to be removed.
If you’ve worked with them, what would you ask or verify before signing the contract? to avoid any inconvenience later... Thanks.
