Estimated Solar Earnings

For Austin Energy customers, solar proposals should not calculate savings and payback periods based on net metering. Instead, Value of Solar rate should be applied to estimated solar generation. Over time, you can recover your system cost through the solar bill credits you earn.

Solar Production Key Numbers

Estimated Annual Energy Production (kWh/year) Production Factor measures how efficiently your system will produce energy. In Austin, a good range is 1,100 to 1,500 kWh per kW. Factors that affect this include:

Formula: Estimated annual production (in kWh) ÷ system size (in kW)

  • Roof direction (south-facing is ideal)
  • Roof slope
  • Shade from trees, buildings or roof features
  • Equipment efficiency

Solar Production Factor

Calculating the Production Factor will help you measure the efficiency of solar systems, and can be useful when comparing proposals. It is a ratio of how much energy the system is estimated to produce (kWh) to the system size (kW). Roof direction & slope, potential shade, and equipment efficiency can affect this number.

Estimated annual production (in kWh) ÷ system size (in kW)

In Austin, a good range is 1,100 to 1,500 kWh

Solar Production Factor

To compare systems of different system sizes, using Production Factor will help you measure how efficiently your system will produce energy. Factors that affect this include:

Formula: Estimated annual production (in kWh) ÷ system size (in kW)

  • Roof direction (south-facing is ideal)
  • Roof slope
  • Shade from trees, buildings or roof features
  • Equipment efficiency

Estimated Solar Savings

For Austin Energy customers, proposals should not calculate savings and payback periods based on a net metering structure. Instead, Value of Solar rate should be applied. Over time, you can recover your costs through the solar bill credits you earn. To estimate your payback period, divide your total cost (including financing or interest) by the average amount of bill credits your system is expected to earn each year.
