Main Line advantage: Larger homes with higher electric bills see the biggest PPA savings. A 12-15 kW PPA on a Main Line home can save $100-$150/month vs PECO rates.
Solar panels in Haverford Township cost $2.95-$3.25 per watt installed, averaging about $3.10/W. For a typical 12 kW system, the gross cost is $37,200 plus 6% PA sales tax ($2,232), totaling $39,432. There is no federal 25D tax credit for homeowners in 2026.
Main Line communities like Haverford tend to have larger homes requiring bigger systems (12-15 kW vs 8-10 kW in inner suburbs). The per-watt cost is slightly higher ($3.10/W vs $2.95-3.00) due to more complex roof configurations on larger homes and higher labor costs in the premium market. However, larger systems produce more SRECs and offset higher electric bills.
All of Haverford Township is served by PECO Energy at $0.21/kWh. PECO offers 1:1 full retail net metering with no proposed changes. Annual true-up excess is paid at the PTC rate of $0.11/kWh. PECO interconnection typically takes 3-5 weeks.
Yes. PA has no property tax exemption for solar. Solar adds to assessed value and increases Delaware County property taxes. For a $37,200 system, expect approximately $400-$500 per year in additional property taxes. This is a significant disadvantage vs neighboring NJ which fully exempts solar.
PPA is particularly attractive for Haverford homeowners in 2026. Since there is $0 federal ITC for cash/loan purchases, but PPA companies claim the 30% Section 48 ITC and pass savings as lower rates, you save 20-40% on your PECO bill with $0 upfront. Especially appealing for larger Main Line homes with high electric bills.
A 12 kW system in Haverford produces about 15 SRECs per year (1 SREC = 1 MWh). At current PA SREC prices of $22-$35 each, that is approximately $330-$525 in annual income. SRECs are registered through PJM-GATS and can be sold on SRECTrade or Flett Exchange.
Haverford Township requires a standard building permit for solar installations, processed in 2-4 weeks. There are no historic district restrictions in most neighborhoods. Your installer handles the permit application and PECO interconnection. Some HOAs in newer developments may have aesthetic guidelines for panel placement.
