2.2 MW solar farm coming soon to a local POCO site. Turning brownfield site into a green gem.

Signed off on the plan review today, it should start construction within 2 weeks.

Pics will be posted IF allowed by POCO.

As long as they aren't "violation" photos, I bet they would like the publicity.

BTW, they have another PV project currently in Planning or Zoning for a similar KW sized job at another facility. The drawings I saw have some really interesting concepts that I have not seen. Architectural concepts, that is.

John,

I just heard that William Paterson University is planning to install the largest PV system in NJ. I heard it was suppose to be about 3MW of power and it is suppose to be installed on everything that doesn't move on campus. I heard this from a small PV installer as I was inspecting his system in town here. The largest I have inspected is a job that had 1000 panels (His count not mine) and put out approx. 400-450 amp at 480 volt. It was running the entire factory including the AC units. ( The AC units were for the office only, not the factory.)

I would be curious to see the bookkeeping on one of these installs. What the capital cost is before the rebates, what the maintenance is, what the true output is and how much the energy bill would be if they just bought the power from the utility.
I assume they do meter the power from the inverters.

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

Posted the first pic; ground mount racking in east field (partial) with a few panels. Sorry for the 'view thru the fence', I thought that was a good vantage point.

More to follow...
