Hi All,
Apologies if this has been covered in dribs and drabs across other posts, but having read a few pages of threads my head hurts and I'm no closer to an answer, so would apreaciate your input and guidance please:
My garage has no electricity and will cost ££££'s to have installed - scrap that idea. So, I've just bought an 80 watt panel (12v) and bolted it to my garage door. Unfortunately, this points due North and is the only side I can put it on (far from idea) so is only ever going to be picking up ambient / indirect light.
I want to be able to gradually build up the system to accomodate more and more as time goes by (as far as the light allows) so am wondering where to start so that expansion is as easy and releatively cost efficient as possible moving forward.
My ideal (ultimate goal) is to have 5 x 80 watt panels (the most I can fit on the door) and have these charge 2 banks of batteries. 1 larger bank to power an inverter that will be used circa once every 2-3 weeks (i.e. hover the car out or a power tool) and a smaller bank that will power low current lighting in the garage and also provide a 12v charging facility for drill batteries etc.
I'm stuck on what type of set up to start with so that expansion is easy. I have 1 panel and a 30amp charge controller at present, so I can link these up to a battery which is fine for now. But when I get a second panel, or want to start building up the second battery bank, will this mean a new controller (1 per bank of batteries) and if so does it have to be exactly the same as the current one?
Also, is it possible that I can feed in 1, then 2 , then 3 etc panels into 2 controllers that then feed the 2 battery banks as I add new panels?
I'm keen that I don't cook or neglect a bank of batteries by having a poor set up and also that I share the panels, so when one bank is full, those panels arent going to waste etc (there won't be enough sun to waste!).
Hopefully this makes sense and is possible, as I don't want 1 panel, 1 cc and 1 battery bank set up twice, they need to share the power as it were!
Many thanks,
Upex
