Hi Paul, Not sure where you are located. I'm guessing somewhere between Yuma and El Paso. While most arrays are essentially self-cleaning from rain and snow, I have observed some arrays located near dirt roads or gravel pits that do collect excessive soiling. These will need periodic washing off ...

RE: How planning for a heat pump affects solar power system design

Posted By Richard Strömberg 08-26-2024 03:22 PM
Found In Egroup: Everything Solar Forum \ view thread

I recommend looking at the CCF monthly totals on their gas bill, converting to mmBTUs and then to watt-hours. Assume that the efficiency of the heat pump will be 2 to 2.5 more efficient than the NG heating system. An easy way would be CCF>>Btus>>kWh *50%. 1 CCF of nat gas has 103,800 Btus. Divide ...

It depends on whether your array might collect the occasional dust/dirt that will wash off with periodic rain and snow or if you experience the more problematic pollen that some locations get. Pollen does not easily rinse off. A close up inspection of your array will let you know what you are dealing ...

Hi Mark, How did you resolve this issue? I recently came across some of these 72 and 142 watt Sharp modules in a donation to our nonprofit. My guess is that Sharp designed these to be wired in series and so long as the watts per string were less than 600V and each string was the same total watts, your ...
