Solar Energy Adoption-Estimating Your Cost Savings for Net metered PV systems by safeenergyhub: 7:36am On May 27, 2017 |
Using the equation below, you can estimate the annual electricity production and electric bill savings for a grid-connected home solar electric system with a net metering arrangement. Determine the PV system's size in kilowatts (kW). A typical range is from 1 to 5 kW. This value is the "kW of PV" input for the equation below. Based on your geographic location, select the energy production factor from the map below for the "kWh/kW-year" input for the following equation. Electricity production from the PV system = (kW of PV) × (kWh/kW-year) = kWh/year You can calculate your annual electric bill savings using the following equation. Note that the residential rate should be in dollars per kWh; for example, a rate of 10 kobo per kWh is input as 0.10 naira/kWh. Electric bill savings = (kWh/year) × (Residential Rate) = naira/year (To determine your monthly electric bill savings, divide the final number above by 12.) For example, a 2-kW system in Ikeja,, at a residential energy rate of 7 kobo/kWh will save about 266 naira per year: 2 kW × 1,900 kWh/kW-year × 0.07 naira/kWh = 266 naira/year (or or 22.17naira/month).Credit- energy.gov Why bother yourself with all these calculations?
