Hi! I admire people, who can make something on their own. I had a lot of troubles with cleaning solar panels in my garden. For instance, you know that you can’t simply use household chemicals and forget about the problem. I made such a mistake and there appeared microfractures. I also thought of doing everything myself, but I realized that the solar panel is too expensive to try my own tools on it. Luckily, I found guys, who've been specializing in repairing
scratched glass and cleaning it for 15 years! They quickly restored the panel, and I didn’t even have to clean after them! I highly recommend you to ask for a professional help.
