"Rui, The cost of the system depends on the size. A 10KW PGM low speed generator with five 2 KW grid tie inverters is about $8000FOB Anchorage."

"Hi all, We have actually produced energy and put it on the grid. Currently the wheel is in for a little work, stiffening and reinforcing. It is very hard to comprehend the forces at play until you see them deform an 1 1/4" axel or a piece of 2…"

"Don, This looks encouraging. I am with you on strong and simple. I look forward to some kW-hr numbers, if you get a respectable output coupled with longevity, you have a winner. Cheers, Jack"

"Hi Don, This looks like progress. You are working on one of the more difficult aspects of drag turbines (as you well know) and that is converting energy from a high torque device to useful shaft work. Will you be coupling this to the generator you…"

Don,

Regarding the power output from the CCHRC arrays in Fairbanks, I live in Fairbanks and work for Remote Power Inc., the company that designed and installed the PV systems at CCHRC. The power output recorded from the arrays at CCHRC is NOT an accurate representation of the power that a PV array would be expected to generate in Fairbanks AK for the following reasons. Here are a few facts that may help answer your questions.

1) one of the arrays was made up of experimental modules manufactured by jxcrystals. The modules have concentrating mirrors and were rated at 180 watts each. They NEVER put out much more than about 120 watt modules so those would be hard to compare with anything..

2) one of the arrays of SolarWorld 165's was left turned off and faced basically true south so they could compare the other array of SW 165's that was tracking, to it. (the non tracking array is the easternmost array of the 4) So that array should only be counted as a fixed array when comparing with PVWATTS.

3) this leaves arrays 2 &3. One of these is an array of 16 SW 165's and one is 16 Sharp 170's. They are on dual axis trackers and as far as I know they have been working flawlessly since installed so they should compare favorably with the PV watts numbers.. EXCEPT FOR ONE IMPORTANT FACT:
much of the time the snow on the modules has been left on the modules. I don't know why they did this but it's true.

One thing anyone contemplating the purchase of a wattsun tracker (like the ones at CCHRC) is that they can't tilt 90 degrees (plumb). The farthest they'll go is 75 degrees and at 75 degrees in a non windy environment like Fairbanks the snow WILL stay on a solar array for a long long time.
