Pennsylvania solar leads

Solar radiation in Philadelphia

Philadelphia, the largest Pennsylvania city in the Census Bureau’s July 1, 2025 estimates, is the reference point. The PVWatts model, first built by NREL and now operated by the National Laboratory of the Rockies, puts the daily solar radiation reaching a modeled array there at 4.73 kWh per square meter (checked October 9, 2026).

Behind the number is the PVWatts version 8 default system: one fixed open-rack array aimed due south with a 20-degree tilt, at Philadelphia’s Census gazetteer location, using National Solar Radiation Database typical-year weather.

Net metering under the Pennsylvania Code

The Public Utility Commission’s net metering rule is 52 Pa. Code 75.13, last amended effective November 19, 2016; the online Code is current through August 8, 2026 (checked October 9, 2026). It requires electric distribution companies and default service providers to offer net metering, first come, first served, to customers generating with Tier I or Tier II alternative energy sources. At a residential service location the system’s nameplate capacity may not exceed 50 kW, and the home must have electric load of its own behind the meter.

Subsections (d) and (e) set the credit. Each kWh the system produces is credited at the full retail rate, including generation, transmission and distribution charges, up to the customer’s use in the billing period. Excess kWh carry forward at the full retail rate, and whatever is left at the end of the year is paid at the default service provider’s price to compare.

Glossary gets the credit terms in that supplier agreement, while the distribution company credits only its distribution rate, under subsection (f).

Two more provisions matter in a sales conversation. Under subsection (i), the customer-generator owns the alternative energy credits unless a contract expressly assigns them. Under subsection (k), the utility may not add fees, equipment or insurance requirements unless they apply to other customers or the chapter or a Commission order authorizes them.

Pennsylvania rowhouses, detached homes and owners

Attached housing sets Pennsylvania apart. In the Census Bureau’s table B25032 for 2020-2024, 691,281 owner-occupied homes are single-family attached units such as rowhouses and townhouses: 18.9% of the state’s 3,656,971 owner homes, a share only one other state exceeds. Another 2,733,276 owner homes, or 74.7%, are detached.

Across all housing units, table B25024 counts 3,287,467 detached single-family homes out of 5,806,452 in the 2020-2024 ACS, or 56.6%, which is the eighth lowest share among the 50 states. For a rooftop installer, a rowhouse roof is usually smaller and shared with neighbors, so attached homes and detached homes are often quoted differently.

What the Pennsylvania facts mean for a solar campaign

For a buyer planning Pennsylvania coverage, the facts above combine into three working points:

• Housing type changes by region. With 18.9% of owner homes attached in the 2020-2024 ACS, a buyer that installs only on detached houses can lean on the county shares when choosing ZIP codes in the southeast.
• The net metering terms are statewide. 52 Pa. Code 75.13 (checked October 9, 2026) applies the same 50 kW residential limit and full retail credit across distribution companies, so installers can explain one set of rules.
• Licensing is local. The Department of Labor and Industry (checked October 9, 2026) leaves electrical licensing to municipalities, so installer credentials are confirmed per municipality.

These points describe housing, rules and the installed base. They are not an estimate of solar lead numbers in any part of the state.
