So, you always believe what a salesman tells you?

Begging your pardon, but we aren't exactly talking about a $500 HP printer at a Best Buy here. The company in question has a track record of propriety and excellence. I am merely pointing out the fact that 3-5% is an invalid assumption.

Do I always believe what a salesman tells me? No. I research facts and make up my own mind given all the information available. In the case of SunPower v. fishman, however, I am going to side with the successful corporation rather than the peanut gallery.

The problem here is the experts on this system are the company representatives, e.g. sales people and engineers. They are the ones who know the best environment for this type of product, but also the worst environment.
The best solution would be to get sales people and engineers from other industries to provide input so at least you have some other options presented to you, and they can tell you potential pitfalls that lie ahead.
To me the real killer is the 16 year break even point is way too long for a commercial product; it sort of smacks of an air of optimism and being just marginally cheaper than the current set up. And if, after 16 years, the schools haven't broken even then the supplier just needs to say "But we didn't factor in that blah blah blah would happen" and they are off the hook.
If those schools were to contact their other local energy providers I think they could provide solutions that would give them at least the equivalent savings, and probably better savings. For example, in the next 16 years LED lamps will have developed to the point that they will have replaced incandescent and fluorescent lighting. They could also do things like insulate their hot water cylinders better, which again would easily provide a 3 to 5% saving when implemented, and by using reflective and double glazed windows they could easily reduce their heating and cooling costs. The cost to do these things is a bit higher now, but would probably have the same 16 year break even point.
To me, these panels will probably end up being attached to the UPS system, which runs the computers etc, which isn't a heavy user of electricity; and that the heavy user things like hot water and air conditioning will still be done by the mains. In short, you will have spent a lot of money and achieved little.
