The solar hot water collectors and passive solar design meet at least 75 percent of the heating needs of the pool and the building. Without the backup propane water heater, the solar hot water system keeps the pool temperature in the low 90s. The PV system meets about 75 percent of their summertime electrical needs, and offsets about 30 percent of the electrical demand in the winter.
The Chings were unable to take advantage of any financial incentives for solar energy at the time their system was installed—no rebates for PV or solar thermal systems existed that were applicable to their systems. But today, with the their utility’s rebate program and federal tax credits, Debbie and Greg are planning to add another array, expanding their PV system to the utility’s financed maximum of 10 KW. Payments for renewable energy credits from their existing systems are also available, which means they may be able to get up to $2.50 per installed DC watt.
To further offset the project’s expense and to share the splendor of the pool house and setting, the Chings now hold classes there, recruiting certified water-therapy instructors to teach students from all over the globe. And, of course, at the same time Debbie and Greg Ching are fostering a sense of community, they’re also showcasing solar technologies, furthering the future of renewable energy.
