its interesting technology to say the least. I have researched, designed and have built several systems. Just got back yesterday from building a small system compared to these utility systems. Rebates and grants can make them economical. These larger systems I would imagine the cost per watt comes down like a big generator versus a little generator. Maintenace cost is really low but the upfront cost is pretty high. Presumimg $4 per watt, thats 8.8 million just for the panals. then there is support framing, wiring, inverters, etc. Being that its a large order, we will cut the cost of panels in half 4.5 million
Another odditity is it will rarly put out 2mW. only when the sun is directly over the panels. Based on data I use from NASA, on average in New Jersey, the system will put out 10 mkW/hr per day. more in the summer much less in the winter. Pesuming $0.10 per kWh for easy coversion, an average of $1000 per day revenue $365,000 per year or just under $11 million over the 30 year life span take 10% for panel degragation over ite life time for a grand revenue. or 9.8 million this would leave about $167,000 a year for the rest of the costs like installation costs, maintenace cost, front office costs, etc. This does not take in account the rising cost for utilities
