How much money will he have to spend keeping the panels operating? And at what point will they have to be replaced?

We currently have refrigerated air (versus a swamp cooler), and I'd almost rather go back to a swamp cooler, as that is what the house originally had, and cutting electricity costs by half, easily. The crap part is they are roof-mounted, and don't work well at cooling the house during our monsoon season, which also corresponds to the hottest part of the year here.
And at what point will they have to be replaced?””
When the first earthquake hits OR the first big wind-hail storm.
