If this is your concern, you should focus on the reviews of the installers. Good installers a) won’t use dodgy products, and b) will do a good job of installation. It might be worth increasing your budget by a small amount so you aren’t getting the cheapest products and installers.
There are plenty of products here that I would personally not want on my roof. Make sure you look at our best solar panel and best solar inverter articles.
