Rain, rain, go away…

It’s been hard to make electricity with all the cloudy and rainy weather we have been having. But it hasn’t been too much of a problem since our charge controller broke on Friday. But if it were working, just how much power can be made under cloudy conditions? Well, the new solar panels (UniSolar PVL-124) on the roof, we should be able to make at least a few amps during the day, unless it is severely overcast. The UniSolar modules are flexible laminates, and are supposed to be better at scavenging power under sub-optimal conditions. These modules are typically applied to standing-seam metal roofs, so options for using these modules are limited. But if you have a standing-seam metal roof that faces south, these may be just right for you, and may help you make power, even when it is raining.
