Why is it still so expensive?
Ding-ding-ding!!! That's the #1 question. It's *not* expensive.
Like all new technologies the price will settle as more demand pulls more providers into the market. Check
the Price List and look at the $ / kW·Hr page for
an explanation on the lifetime cost of energy.
How much area for 250kW?
This is the basic size for a medium commercial genset. Figure about 2.5 acres1. That
sounds like a lot, but that's what the panels require for spacing. That spacing allows your system to
generate full power for 8 hours per day on average, all year.
How much power for a 50,000 sq ft roof?
Because we provide a border away from the edge of the roof, you should be able to mount a 100kW system on a
roof of this size. Again the space around and between the panels is important for maximizing the
effectiveness of the system.
Do you have a price list?
Yes. Here a price list.
When is your Residential offering ready?
As soon as we get some serious interest in residential systems. (sorry)
We're planning a small residential system that will fill the gap between 5 and 50kW. It's difficult for us
to get much smaller than 5kW without a major redesign of the panels and the engine.
1 An acre is actually 43,560 sq. ft. a square about 208ft. 8.5in on a side.
