NET BILLING VS NET METERING Net Billing - Customers can sell any excess energy they generate back to the utility at pre-determined wholesale prices. Both consumption and generation are recorded and billed separately. As a result, customers get charged their full retail rate per kWh when they use energy from the grid, and are paid a wholesale price by their utility when they sell it back. Net Metering - Measures the energy customers generate each billing cycle. Sending excess electricity back to the grid accumulates kWh credits when your solar array generates more energy than you can use. Customers then get charged based on their net usage of kWh at the end of each billing cycle. 4/25/2018 SESA Home Owners Experience 13

WHY DID I DO SOLAR? SA1 2008 • Replacing roofing anyways, interested in solar • 3 early teen kids who learned a lot about solar • ROI – over 30 years ouch! • Could have bought a new vehicle, but…. • Potential increase in energy price / savings • After doing EE, right thing to do SA2 2017 • 3 young adults who will be future leaders • ROI – reasonable 7 years! • Saving money – doing laundry when the sun shines • NDP incentive program (recoup carbon tax) • Right thing to do, after doing EE! 4/25/2018 SESA Home Owners Experience 15
