The day your solar panels are installed is the day you will get the best performance out of them. After that it is all down-hill. Admittedly, it is a very shallow hill and it might take over 40 years to get to the bottom, but day one is going to be as good as it gets.
One of the reasons for this is dirt. As soon as your panels are out in the open in the clean air, or not so clean air, dust will start to settle on them, blocking sunlight and reducing their efficiency.
If you need your solar panels cleaned, email or call us and let us do the cleaning.
The obvious solution is to pay someone to clean those panels or get out there and clean them yourself. And sometimes this obvious solution will be a sensible course of action. If a dust storm has covered your panels in dirt or pelicans have had a poop party on your roof, then it’s a pretty good idea.
