The team here at Arzon Solar is often asked to compare our uModule performance to that of conventional c-Si flat plate modules. So, the purpose of this blog post is to show a clear example of how the Arzon Solar uModule compares kWh to kWh against using conventional c-Si flat panels, in this case the Astronergy 300 Silver Poly CHSM 6612P-300.
First, the calculations. In a high DNI environment (Palmdale, CA in this example), Arzon Solar uModule generates about 2,600 kWh / kW CSOC, with a uM2 CSOC rating of 4.6kW. So, a single uM2 generates 4.6*2,600 = 11,960 kWh / yr.
A fixed tilt mounted flat panel can be expected to generate about 1900 kWh / kW STC. The STC rating of a single 77″ x 40″ panel is 300W. So, we have 11,960 /1,900 = X * 0.3, solve for X and we get 21. Without considering the fact that uModule suffers only 30% of the temperature degradation of s-Ci modules, or the lower annual degradation rate, we would need 21x 300W Astronergy panels in a fixed tilt mounting to meet the same energy generated by a single uM2. So, we add 1x more panel, to make up for the temperature and degradation characteristics, as well as make a more symmetric scaled picture above. 🙂
The result is simple. uModule systems take less space and deliver more energy per given land then conventional c-Si modules. Don’t you deserve more energy from your land? We think so.
