How do you vet your installers? Finn Peacock December 05, 2017 10:39 Updated Follow I explain how I pre-vet each and every solar installer that applies to join my network here. Related articles I've been told my maximum solar system size is 5kW. Is that correct? I think I'm ready to make a decision about solar for my home or business. How can I take the next step and get a quote for a system? How do I estimate the energy output of a solar system throughout the year? How does SolarQuotes make money? How will my off peak hot water service work with my solar system? Comments 0 comments Please sign in to leave a comment.
