I'm new to installing photovoltaic systems, but I'm a quick learner. I
want to ask for your advice about using apps. They are becoming more
and more popular, and, to be honest, what they offer seems quite
promising, like azimuth calcs and shadowing simulations, etc. I mean,
all the calculations scare me a bit, and having an app on my phone
would defenitely make things easier... but I'm not sure if it isn't
just better to ask for professional help. Have any of you used that
sort of apps (like http://easysolar.co/ )? Your opininons? Are they worth it?
