I’m putting a new off grid solar system into my home in Spain. I’ve owned the home since October and it came as a small surprise to learn it needed changing immediately. As such, I’m on a step learning curve.
I have estimated my optimal needs to be around 30kw a day (although current usage is about 20kw), with between 5 and 10 hours of usable solar radiation a day (on the worst day in the last 15 years this dropped to 2 hours).
I have 3 quotes, and I would welcome any insight on how best to evaluate their merits.
Thanks in advance
