I have pretty good hands-on skills and do most projects around the house myself. For example, I installed heat pumps throughout the house by myself. I am considering purchasing a 14.6kw DIY system from a company called solarwarehouse.com but have read that they can be difficult to get support from after a sale has been made. So, I was wondering if it genuinely is pretty easy to install this equipment with basic DIY skills (I am good with calling on my local electrician for making final connections)?
