Triple-deckers dominate Lawrence housing stock and are surprisingly well-suited for solar. Their flat roofs, large surface area, and multi-unit structure create unique advantages for solar installation.
Triple-decker flat roofs provide 800-1,200+ square feet of usable solar area. Panels can be tilted to optimal angles using ballast mounts -- no roof penetrations needed. A typical triple-decker roof supports 7-12 kW of solar panels.
Building owners can install solar to offset electricity for all three units, splitting costs and savings. Each unit may independently qualify for SMART low-income at $0.06/kWh. The economics work well even if you only own the building and rent the units.
For renters in Lawrence triple-deckers, community solar is an excellent option. Subscribe to a local solar farm and save 10-20% on your National Grid bill with $0 upfront cost and no installation required. Ideal for the large renter population.
Lawrence's neighborhoods vary from dense triple-decker districts to more suburban single-family areas. SMART low-income eligibility is high across nearly all neighborhoods.

Solar panels in Lawrence cost $2.85-3.20 per watt installed in 2026. A typical 10 kW system costs $28,500-$32,000 before MA state incentives. The federal Section 25D residential tax credit expired December 31, 2025.

Lawrence has the highest concentration of environmental justice populations in Massachusetts. A large percentage of households fall at or below 80% of area median income, which is the threshold for SMART 3.0 low-income eligibility. At $0.06/kWh, a 10 kW system earns approximately $720/year in SMART income -- nearly double the standard rate. This makes solar in Lawrence among the most attractive investments in the state for qualifying households.
Yes. Triple-deckers are actually ideal for solar because of their flat roofs with large surface area. A typical Lawrence triple-decker roof can support a 7-12 kW system. Building owners can install solar to offset electricity for the entire building. Each unit may also qualify for SMART low-income independently. Many Merrimack Valley installers specialize in triple-decker installations.
Lawrence is in National Grid territory at $0.32/kWh. Net metering credits are 1:1 at full retail rate, rolling over monthly with an annual true-up in March. National Grid ConnectedSolutions battery rates are $225/kW summer + $50/kW winter. SMART income is identical regardless of utility.
Absolutely. Lawrence may be the best city in Massachusetts for solar ROI for qualifying households. With SMART low-income at $0.06/kWh, lower installation costs ($2.85-3.20/W), and full net metering, the payback period can be as short as 5-7 years. Even at the standard SMART rate, a typical system saves $95,000+ over 25 years. The low upfront cost and high incentive rates make Lawrence an outstanding solar market.
