Historic Townhouse Embraces Solar Energy
Location: Washington, DC
Annual Estimated Savings: 71,769 kWh/year
Challenge
A historic chapel built in 1929, recently converted into a townhouse, sought an environmentally friendly energy solution that could reduce electricity costs without requiring significant upfront investment.
Solution
Pacific Sun Solar developed, owned, and operated the solar installation, providing the building owner with clean energy benefits and financial savings through an innovative leasing model.
Key Project Features:
- Solar Energy Generation: The rooftop solar array generates approximately 71,769 kWh annually, reducing reliance on the local utility grid.
- Zero Upfront Costs: The system was installed with no out-of-pocket expenses for the building owner.
- Power Purchase Agreement (PPA):
- Offers a competitive rate for electricity, significantly lowering costs compared to PEPCO, the local utility provider.
- Locks in a fixed rate for electricity over the system’s lifetime, protecting against inflationary power cost increases.
- Multiple Rooftop Installations: Solar panels were installed across multiple buildings on the property with two interconnections for maximum efficiency.
Results
- Annual Energy Generation: 71,769 kWh
- Electricity Savings: Locked-in discounted rates
- Environmental Impact: Reduced energy consumption from non-renewable sources, helping meet DC’s renewable energy targets
Impact
The project highlights Pacific Sun Solar’s commitment to enabling historic and multi-use properties to achieve energy independence and cost savings:
- Economic Benefits: Reduced communal area electricity bills and a reliable revenue stream from the leased rooftop.
- Environmental Benefits: Clean energy reduces the building’s carbon footprint while contributing to the community’s sustainability goals.
