I did get a quote from smaller installer. Around 14K for a 6.6kW or 18K for an 8.8kW system. That's the installed estimate. If we wanted to add battery storage it was around another 11.5K extra which isn't worth it right now imo.
Having concrete tiles, they mentioned they would need to lift some tiles when installing as the mounting bracket would get attached to the trusses underneath.
Not really, it sounded like they had done it before. They asked if we do replace tiles to get some extra ones as some in case any break during installation. They were happy enough even before I told them I was going to get a roofer to look at it first.
IIRC the installer I spoke to reckons batteries will come down in price in the next few years. Makes sense to me with more EV's being produced, there should be some advancement and increased availability in battery tech. He did mention panels were actually cheapest to install around 2021, there was some supply issues during the covid times but prices are returning to normal for panels.
Interesting. Maybe I should slowly start doing some shopping around for panels and a setup that would allow for relatively easy battery add-ons down the line.
