11:00 am - 11:30 Host: Topic of Discussion: How much does it cost to put up a solar farm on a 30 acre piece of land?
At 18% efficiency, 1000 Wp(solar)/m2 translates to 180 Wp(electrical)/m2. 30 acres is 121,406 m2. That’s 21.85 MWp(electrical). At $4.50 per peak watt that’s $98.33 million capital cost. Each watt peak electrical averages over the year 188 milliwatts given the fact its not sunny all the time. So, that reduces you average power output to 4.1 MW. That’s 36 million kWh per year. At $0.11 per kWh that’s worth $3.96 million per year. This just about covers your maintenance costs only. Using advanced concentrating solar panels that are 55% efficient, and convert rain water and sunlight into hydrogen gas, and using the hydrogen gas to run gas fired power plant at 36% efficiency121,406 m2 * 550 W/m2 (peak) * 0.188 utilisation * 0.36 (thermal) = 4.52 MW avg. Which is about the same, but the fuel gives you the flexibility to load match, and operate at night. At $0.11 per kWh this produces a revenue of $4.355 million per year. A 30 year contract is worth $130.6 million. The present value of the revenue stream over the same term, when discounted at 8% is $52.95 million. These are so cheap, MOKENERGY for example, sells the power not the equipment. You provide the land, and the company does the rest, is their motto. An off-take agreement at $0.11 from a credit-worthy buyer and the payment of a 10% of the contract discounted value ($5.95 million) as retainer for a study, and you’re good to go. Tax credits, carbon credits, and other benefits, are worked out as well and reduce power costs. Power costs are fixed over the 30 year term.
