Hello my name is William Galgan I have been looking in to power generation methods for a couple years doing research on different ideas. I am looking to start a Solar/ Green Power Plant witch could be duplicated in many towns locally. The idea is to start with a solar Pv array and move on to wind, biomass and other related technology’s. I have land to start with but have been looking for investors with little results. Unfortunately i am not as knowledgeable on some things as i would like to be (finding investors). So at this point i am at a stand still, I am looking for a partner or some direction to head in any help would be appreciated. Thanks
The return on Pv arrays is about 16% a year despite the initial cost and your money is almost doubled before any of the warranties expire on the equipment.

goodluckk!
Well man, before I read your entire paragraph, I said all you need is lots of money. Photovoltaic arrays are quite expensive. Can’t help you there! I do however, admire your passion for science to create better ways to alternative energy. Keep up the good work and good luck!
If you have 10kW of panels, it means they produce 10kW when square on to the full sun. This will produce 10kW for 5h a day on a good day, on average, in a good region (10kW x 5h = 50kWh). The amount actually fed into the grid is less by about 25% due to losses, so 38kWh per day. This assumes 5 equivalent full sun hours a day, though the sun may be shining for 10 hours. This is more likely to be only in tropical regions, especially when averaged over a year. In temperate zones the average over the year may be as low as 2 or 3 hours a day.
The very best production is not likely to be greater than 14MWh per year, but could be as low as 4MWH per year. One MWh is 1000kWh (electrical units for payments). At 10c per unit, then expect from $ 400 to $ 1400 per year from 10kW of panels.
Of course it depends what price you buy the equipment for, and what feed-in tariff (payment) you get. Consider that larger scale systems (>10kW) might have individually negotiated (lower) rates from the power authority. Look into this very closely – it is not what you think I expect. A consultant can give you production figures for your local region, and advice about subsidies, tariffs, connections, environmental impact, energy certificates and such.
Australian example.
The installation cost (incomplete cost, for equipment, not land and structures) is like $ 63000. Very basic calculation gives 1400/63000 = 2.2% best case. With subsidised tarriffs that could be as high as 50c a unit, so 7000/64000 = 11.1% best case. It could be a lot less, like 400/63000 = 0.63% Personally I don’t think subsidies can be guaranteed. Governments can cut them off with the stroke of a pen.
The link below has some realistic stuff. Note that an REC is a renewable energy certificate, a government subsidy, which the supplier/installer will often buy from the customer to reduce the cost to the customer. There are various government subsidies to buy equipment, but these tend to be meaningful for a small system only.
