Seventh Gen Solar

Seventh Gen Solar is a family-owned, New Hampshire-based solar and electrical installation company with 10 years in business by its own account, taking on net-metered and off-grid solar systems, battery backup, EV charging and standby generator work for homeowners and commercial customers. Customers who hired the company for solar installs consistently praise two people by name. In two 2026 reviews, homeowners describe installer Nate taking time to walk through options and building the system around their own priorities rather than a standard template, with clean, well-thought-out execution. A run of 2024 reviews credits crew lead Ben and his team with efficient, on-time installs that leave the site tidy each day. Further back, a 2022 reviewer says the company diagnosed and warranty-replaced a failing power inverter and reintegrated it with their existing panels, and another 2022 reviewer describes the company beating its installation timeline and having a team member walk them through managing the new system after their utility installed the net meter. One thing worth asking about directly: a 2022 reviewer says that after they accepted a quote, the company stopped returning calls and emails during the follow-up stage, with a full voicemail and a promised callback that never came. It's the one discordant note in an otherwise strongly positive, multi-year record, and it's worth confirming a firm install timeline in writing before signing. For homeowners looking to add solar, battery backup or EV charging in the region, the installation work itself draws consistent, specific praise from named customers across four years — just get the post-quote handoff nailed down before committing.
