Cogenra Solar is a solar cogeneration systems and renewable energy service solutions provider. It announced that it completed a solar cogeneration project at General Hydroponics, which is the leading manufacturer of indoor agricultural systems and fertilizers for crops.
The General Hydroponics facility is located at Santa Rosa, California. Cogenra Solar installed a 75 kilowatt solar system that will boost its existing photovoltaic system. This increases the company’s solar power savings with its solar powered electricity and hot water system.
General Hydroponics installed its first commercial solar electric system eight years ago. But it hasn’t addressed its fossil fuel demands for heating water until now. The company needs hot water to make its nutrient blends.
Now the company has solar cogeneration system that provides both electricity and hot water. It expects a return of investment from the newly installed system in less than five years. It would also protect its finances from future increase of fuel costs.
You can find General Hydroponics brands in the market under the brands Alice Garden, General Organics, and General Hydroponics. The heat generated by the Congenra Solar system is used to heat water that is needed to manufacture the nutrient blends found in most vegetable and flower supply stores across the globe.
The 75 kilowatt system is a combination of 60 kW of thermal energy and 15 kW of electricity. It contains 36 Cogenra photovoltaic thermal panels that are mounted through standard solar racking system on General Hydroponics’ rooftop.
Its system can offset 3,500 therms of the plant’s natural gas usage, which results into an estimated 60 percent of its annual consumption. Its electricity output offsets the company’s existing 101 kW photovoltaic systems. The system took less than three weeks to complete.
Cogenra’s system is IED and SRCC certified for electric and thermal rebates, which includes the California Solar Initiative or CSI. The CSI thermal rebates give $12.82 per therm of offset gas in the first year. These rebates result to faster payback than traditional solar hot water or solar electric systems on their own.
Gary Gerber, president of Sun Light & Power, said that Cogenra’s combined solar hot water and electric systems deliver more energy as a whole and have a much lower costs than the conventional renewable energy solutions. It would accelerate the adoption of solar power in California.
Cogenra Solar is pleased that General Hydroponics chose its system that delivers five times the energy generated by traditional PV. It also decreases the amount of greenhouse gas released by three times that of conventional solar power installations.
