Project Overview
Solaris Renewables recently completed a sophisticated solar and battery installation in Andover, Massachusetts. The project involved a classic garrison colonial home with multiple roof surfaces, including a primary south-facing roof, an attached garage with living space above, and a smaller screened porch. The young, tech-savvy family—both IT professionals working from home—needed a solution that not only reduced their monthly electricity costs but also provided reliable battery backup to support critical systems, from climate control for their toddler to maintaining sensitive computer equipment during outages.

Design & Planning
During the initial consultation, the homeowners expressed their dual priorities: economic savings and environmental responsibility. Recognizing that energy storage was as crucial as solar generation, Solaris Renewables designed a system that integrated both. The primary design focused on harnessing maximum solar exposure from the main roof.
However, the site presented challenges: obstructions such as skylights, a brick chimney, and venting elements segmented the roof, while a new photovoltaic rooftop setback code required the incorporation of a fire pathway. This regulation mandated a clear channel on the largest roof surface to ensure safe access for firefighters in emergencies.
To overcome these obstacles, the design team reconfigured the solar array into two cohesive sub-arrays divided by the fire pathway. Initially, the project was set to use premium plus 400-watt panels, but later switched to ultra-premium 410-watt all-black panels. Paired with a 10-kilowatt SolarEdge inverter equipped with module-level optimization, the final design ensured efficient performance even with a solar access rating of 79% due to nearby shading from trees and surrounding structures.
Installation
The installation phase was complex and required additional electrical work. As the project evolved, unforeseen challenges emerged: routing wiring for the battery system through a finished basement, coordinating with multiple trades, and managing obstructions while adhering to stringent code requirements.
One notable hurdle was addressing deteriorated siding and trim behind the service meter. The Solaris team promptly replaced the rotted materials with a PVC backer board and new siding, ensuring that the home improvement aspect of the project added long-term value. Moreover, the installation involved upgrading the home’s electrical service. Originally equipped with 100-amp service, the homeowners desired a 200-amp upgrade.
Due to underground utility constraints, the upgrade was revised to a 150-amp service—a solution that balanced feasibility with the client’s energy demands. Throughout the process, Solaris Renewables’ close relationships with local inspectors and utilities helped navigate these challenges efficiently.
Results
Post-installation, the system—rated at nearly 9 kilowatts with an integrated 10-kilowatt battery—has significantly reduced the homeowners’ energy costs. When installed in 2023, their average electric bill was $223 per month on 31-cent rates; with current rates rising to 38 cents, the system now generates 81% of their energy needs, saving approximately $289 monthly.
Incentive programs further bolstered the project’s financial performance. Participation in the SMART program yielded nearly $5,000 over ten years, while the battery incentive program added up to $5,000 over five years, along with tax credits exceeding $16,000. With an upfront investment of just over $50,000, the payback period for the integrated solar and battery system was achieved in seven years—a remarkable result considering the additional complexities introduced by the battery system.
Conclusion
This Andover solar installation is a great example of Solaris Renewables’ consultative approach and technical expertise. By carefully designing around roof obstructions, adapting to evolving code requirements, and managing complex electrical upgrades, Solaris delivered a tailored solution that meets the financial, operational, and environmental needs of a modern, energy-conscious family.
