Does your power project require that you produce power from solar 24 hours per day everyday of the year, i.e., baseload power? Or does it require that you produce power from solar just during peak times, i.e., is it a peaker operating 4 to 6 hours per day? Or is the requirement somewhere in between, say, 7-9 hours or so a day from solar, i.e., an intermediate power plant?
247Solar Plants come in four standard models to address each of these three basic types of power generation systems, i.e., peakers, intermediate power, and baseload power. The smallest, 300 kWe, can operate as a baseload plant with a solar capacity factor of 60-80% 1 . The next two sizes, 600 kWe and 900 kWe, operate as intermediate plants on solar power for 7-12 hours per day, e.g., some daytime hours as well as some morning or evening peak hours. The largest size, 1200 kWe (1 megawatt) operates on solar power primarily during morning and evening peak hours. All models are designed to burn fuel, if desired, to extend their operation and/or to enable them to be firmly dispatchable, i.e., to operate whenever required. Also, all three models can perform as “spinning reserves” by operating the turbines continuously at a very low rate (and very low solar or fuel consumption) in order to respond instantly to fluctuating demand or sudden drops in voltage on the grid (e.g., when a cloud crosses over a PV array). Models can be mixed and matched in systems of multiple 247Solar Plants to maximize the total revenue stream. The turbines can be shipped from the factory to burn either gaseous or liquid fuels.
