cost of large photovoltaics for commercial location
Generally, Solar PV systems that generate electricity from sunlight cost between $2.50 to $7 per installed watt. Typically, the larger the system, the lower price per watt.Large commercial systems are typically well below $4 per watt.Residential systems, because of their smaller size are usually somewhat higher. For example, in Ohio a 5 kW residential system with an average monthly production of about 530 kWh would cost approximately $19,000 or about $3.77 per watt.arge commercial systems are typically well below $4 per watt.

Between 150 megawatts and 1,000 megawatts, the costs climbed from about $2 million to $20 million, adding up to $3 to $5 per megawatt-hour, the study found.verall, NV Energy would need to keep about 1 megawatt of generating capacity online for regulation for every 25 megawatts of PV, the study found, and it would have to be fast, with 1 megawatt-per-minute in ramping capacity for each 75 megawatts of solar.
