Gridley, California – Stapleton-Spence’s fruit processing and co-pack facility has the largest solar water heating system ever installed in California, saving the company 37,584 therms of natural gas annually. 37,500 therms is equivalent to 1 million kWh or a carbon footprint offset of 1.4 million pounds of CO2, the equivalent to 2,000 cars annually, sources say.
The new solar thermal system includes 20,000 square feet of solar panels on the roof of the processing facility. The sun is used to pre-heat well-water that flows through the tubes of each panel. About 650,000 therms of natural gas are used at the Gridley plant each year, primarily to rehydrate dried fruit, and sterilize purees and juices before packing in airtight containers.
“We use the solar thermal system to pre-heat well-water before it enters our boilers. Our specialty is applying the right amount of heat to sterilize food products and then to pack in containers that maintain the sterile environment. This lets us preserve foods without chemical preservatives", says Brad Stapleton, President of Stapleton’s. Stapleton’s uses about 30 million gallons of water per year, with about one third of that going to the boilers. Well-water is pre-heated by the new solar system and is sent to the boilers approximately 30 degrees warmer, where the boiler does the remainder of the heating.
Being good stewards of the environment isn’t new for Stapleton’s. “We have a 2 million gallon on-site water treatment plant that’s been active since 2000,” says Mr. Stapleton.
