Solar Electric Solar Hot Water Net-Metering
The solar electric system consists of flexible thin- film amorphous silicon solar photovoltaic panels that were installed in 2005 on the existing south-facing standing-seam metal roof of the conference center. This system is net-metered with a direct grid intertie to DP&L’s electric grid through an electric inverter. The system is rated at a maximum production of 2 KW and has been producing an average of 2,500 KWH of electricity per year.
Solar electric systems are great for supplementing existing electrical resources; however, at the present time, solar water heating systems are more economical. According to the Department of Energy, about 13% of electrical consumption is for hot water heating. Installing a solar water heater can save on average 50% to 80% on water bills and protect against future fuel shortages and price hikes. The solar electric system at Madison Lakes Training and Conference Center is net-metered, which means that extra energy produced by the solar electric system (above the usage of the facility) literally spins the electricity meter backwards.
Although at the present time there are no solar water heating systems installed at Madison Lakes Park, future plans may incluse installation of a solar water heating system.
When an individual uses electricity from a local utility provider's (DP&L) electricity grid their electricity meter spins forward. Net-metering is when electricity produced by an individual is fed back into the local utility provider's grid and it spins their electricity meter in the opposite direction. Ohio state law mandates that all electricity providers must use net-metering. Using net-metering, it is possible to achieve net-zero energy usage for a facility. This means that even though an individual may use electricity from the grid, enough energy is produced by the individual to bring their net energy usage to 0. Net-metering provides the independence and cost effectiveness of producing your own energy while still providing a back-up energy source.
