Day 37 of the 365 to 40 project. We just signed on to get a decent solar power array installed on our roof, here in Australia there’s really not that much of an excuse not too. This shot is also of a solar panel but one from a solar powered venting fan I fitted to the bathroom to help pull heat and humidity out. The bubbles are imperfections in the panel, not a huge problem in a vent fan but not something you should be seeing in your roof panels.
