You have gone solar. Congratulations! It's a really good choice that provides you with greater energy independence and substantial savings. It also makes a real difference in the quality of the air we all breathe. Those panels also represent a substantial investment. Though they save you a lot over time, you have spent a good bit on them, and they have greatly increased the value of your home. The last thing you want is to have to replace them because of critter damage. In fact, you could spend months wondering why your power production has gone down before discovering the damage.
