The efficiency of a solar energy system is determined by several factors, including the efficiency of the solar panels, the inverter efficiency, shading, orientation, and tilt angle of the panels, as well as environmental conditions such as temperature and sunlight intensity.
A 12kwatt solar panel system is approximately 842 square feet. It’s best possible efficiency is 24% (current record). At most it will be affective for 25 years. The cost is about $20,000.00. A WringerSolar solar energy system is about 1/3 the size at 324 square feet. It’s average efficiency is 82%. It’s longevity is 60 to 100 years or more. The cost is $70,000.00 at the dock ($50,000.00 at time of order and $20,000.00 at the dock, shipping and handling are more.)
Low Failure Rate Make it the best. PV cells don’t fail very often but they do fail. When they fail they fail open, (electrical term). Measuring a failed PV cell from positive to negative or negative to positive will read infinite resistance and no power out
