There are several advantages to having solar panels in sunny Arizona and if you have enough space for them, they can be your sole source of power in your homes or office. One question, however, is whether your solar panels continue to be as efficient during the monsoon season or when the clouds are dark over your home.
This is a valid question to ask because clouds and dark skies do depreciate the efficiency of your panels. Thats why we suggest batteries and/or not completely going off grid for power. In fact, during extremely cloudy conditions, your solar panels can decrease in efficiency by 50%.
