We had solar panels fitted last year, and I wish I had seen your article then as we grossly underestimated the amount of panels we would need for our house, so it was extra expense in the end as we had to get more panels fitted with a bigger system.
We also didn’t even think of doing a roof inspection first, which we should have done, as if there is anything wrong, now it is going to be extra work to take the panels down again.
But all in all we are loving our solar energy and are saving a lot on our electricity bill each month.
Hi Michel, I’m sorry to hear of that! But happy that things have resolved in the long run. I wished I knew these things too back then. That’s why SolarElectricNow is here – to be an information resource and help others get started in solar right the first time!

It’s surprising how often homeowners overlook permitting and inspection steps during solar installations. I’ve seen this delay entire projects unnecessarily. I’m curious, have you found that certain regions are more prone to permitting issues than others? Also, the point about improper panel placement really resonated with me. I once helped a friend relocate panels because their initial installer didn’t account for seasonal shading from nearby trees. Do you think more homeowners should consider doing a solar site analysis themselves before hiring a company, or is it better left to professionals? This list made me think twice about the steps I took with my own system, especially regarding inverter placement and maintenance access.
Hi Slavisa,
The things that can “bite you in the behind-sight” for lack of research and preparation. Frankly, I would think it best for homeowners to do both. Do your own site analysis because you know your property, then share your analysis with a professional and have the professional do theirs with your observations in mind.
Thanks for sharing your experience!
