*This is an estimated amount based on assumptions above
*Assumes solar panel size of 400 watts each, arranged 6 panels high in landscape orientation.
*Assuming a south-facing array at 25-degree tilt with minimal shade in Lancaster, PA
**Assuming an electric price of 11 cents per kWh
***Assuming an SREC value of $25 per SREC (PA State Incentive)
****System price assumed at less than 100 feet of trenching and no electrical upgrades.
*****Assuming a 26% federal tax credit on total system cost
******Assuming electric bill and SREC savings over 10 and 30 years, with 3% annual electric rate inflation, 0.5% annual solar production degradation, and $25 per SREC
