Buyer beware. Have experience with three neighbors that added solar to their homes. A few seldom told truths,
solar panels don’t last forever, they are subject to decreasing efficiency over time due to, uv degradation, abrasion of surfacing, damage from birds bugs hail, thermal shock,
a home roofing system not designed from the start for panels may not handle the weight load, the fasteners and wires entering shingles, sweating underpayment, cost of leak repair and expense of accessing damage panel or roof shingles, leaf entrapment, rot and time delay to discover the rot, lightning strikes and damage /system failure,
selling energy back wholesale rate but using at consumer rate, battery bank, battery like span of five years, electric grid tie in hardware cost and insurance
insurance coverage denials, contractors under insured, fly bynite
lack of adequate sun, panel angle, clouds
but the biggest is sustainablity, it takes more btu s to make a solar panel than it can create in its life time, think how glass is made, silicon sheets created, all those processes and the pollutant byproducts, do the math
All three neighbors had to replace not only their roofs but truss and ceiling repairs not covered by state farm or Allstate, Goshen NY.
