Hello again, I will say this, then opt out:
None of these panels are *reliably rated for durability or output that I have ever seen... their competing claims mean absolutely nothing without the guaranteed lowest price... and guaranteed longevity... and seller guarantee is by virtue of giving the panels to you free for a share of the savings you get.
No other company will do that for you....that is the proof of the pudding so to speak... if they could, they would, but they do not. The fact is that most of the panels sold today are made by the same few chinese manufacturers, the quality is close, proving it on a product that has not been on the market long enough to prove its longevity is humanly impossible.
However no proof is needed when a company will install the produce at no charge to you.
A company like that dominates its market 10 to 1... it beats the pants entirely off of its competition for that reason. Its incentive is to provide the best on the market so that THEY make a lot of money and can afford to sign such a contract.
Having said that, there is no need to rate me for my time spent explaining this to you... good luck with your project. I will opt out on the very slim chance that anyone else here, or elsewhere on the planet can provide a provably better evaluation of the panels, or the overall situation.
Good luck with your project.
