Yes you are correct. Santan solar out of Tuscan Az. Has solar panels as cheap as $50. The cost of shipping is another story. I would plan a trip to Az and pick them up while enjoying an adventure, two birds with one stone as they say.You claim it's expensive, but what about used solar equipment?
Yes, solar panels do lose their power over the years. But with a lifespan of up to 20-40 years, a solar battery that has worked for 5-10 years can still serve a new owner. Especially considering that the typical capacity degradation is only 0.5% per year.
