Sorry to cast a "shadow" over this wholesome picture of silicon panels basking in the Palm Bay sunshine. First of all , if your FPL bill has been reduced as a result, please advise, (my bill has increased during all of this solar installation), thus I'm not seeing a payback. (doubt anyone else is) Doing some quick math , this comes out to ~5kW per house (and that would be only in the daytime since there is no mass-storage battery technology today to store power for use during the nighttime hours). What's the opportunity cost to the taxpayer of the land use? (Im sure they got a prop tax incentive to put it there). The other fallacy here is that this is "clean" energy generation. Solar panels are manufactured in a similar fashion to semiconductor chips. It takes a lot of energy to produce one (estimates are it takes ~5yrs for a panel to replace the energy it took to manufacture it). Again , if you want to gauge the impact, we have a local example of semiconductor manufacturing @ the old Harris Semiconductor /Intersil facility on Palm Bay Rd & Lipscomb. Take a look at the transformer station (across from the Post Office) and the heavy bus-work that runs thru the campus. (It could power a small municipality) . The manufacturing process is dirty, it utilizes acids, solvents , photo-resists, boron etc, all which have to be disposed of (the current method is to expel the waste into injection wells). Btw, this site is a EPA Superfund Site because decades ago, some of these materials had polluted the site. The panels do eventually wear out, and the process starts all over again. The worn out panels have to be disposed of. The Orlando Sentinel recently reported that the Orange County Convention Center was replacing its roof panels, they were giving them away free to residents (so presumably they didn't have to go thru a arduous process of disposing of them). We should root for manufacture of these panels in China, so they can pollute their Country instead of ours.
