“I better have solar because electricity is very expensive” Rising electricity prices is what drove Lenny Pfister, a retired NASA scientist of over 40 years, to put a solar system on his home at the age of 72. Pfister said the 1960''s homes in his area of Northern California historically haven''t had air conditioning.
Over time, exposure to sunlight and UV rays can lead to a decrease in the performance of solar panels. Each year, solar panels experience a small decrease in efficiency, typically ranging from 0.7% to 0.8%. This annual degradation adds up over time and can significantly impact the overall output of the panels.
