let me know where you can buy solar panels with a 25 year warranty. I'll go buy some to replace my dead ones.

SunPower Solar Systems SunPower Solar Panels come with a 25 year warranty on the power production of their panels. Because there are no moving parts, the only wear-and-tear these systems see if from the sun beating on them year after year. This is factored into the 25-year warranty, which states that by the end of the twelfth year, the panels should still be producing at 90% of their initial capacity, and that by the end of the 25th year, they should still be producing at 80% of their rated power.

U.V. kills them in five to seven years.

I know. I have worked withe since the days of Arco Solar
in Camirillo Ca.

30 years and barely any progress.

The panels degrade and they become useless after 5 years on average. I should know, I go though enough of them. besides, it isn't the silocone part that breaks, its all the little connections that corrode and short out. Or the seal starts leaking and they get moisture in them.

At any rate, try collecting that warranty. Read the fine print.

But don't come here and try tell an experienced off the grid self sufficient user of windmills and solar panels how 'great' solar panels are or how long they last when all you have ever done is read "fabulous" claims from an internet site add.

Even if solar panels lasted 25 years, the cost of them and the cost of all the battery banks, windmills, back up generators, inverters, charge controllers, towers and all the maintenance that goes along with it makes getting your electricity this way far, far more expensive that what you get sitting on your butt plugged into "the grid". It is so expensive that there is no hope of ever recouping my investment from money saved paying the electric company.

Plus, because I live way out in the sticks, I can have a couple of windmills buzzing away and a couple banks of panels. You can't do this in urban areas. There are by-laws preventing you from doing so in most places, and there is no way smaller windmills will do you any good, except make a nice lawn ornament that can maybe light up a tiny lightbulb at night .
