We design and install full solar arrays for remote properties, cabins, and homes seeking total energy independence in New Hampshire.
Store the power your panels produce and use it around the clock. We install both carbon-lead and lithium battery banks, sized to meet your actual energy needs day and night.
Add a backup generator to your off-grid or grid-tied system. A generator keeps you covered during extended cloudy stretches or unusually high energy demand.
When a rooftop is not the right fit, a raised pole mount gets your panels into the best possible sunlight. We handle the full structural design and installation from the ground up.
Most solar installers in New Hampshire stick to standard rooftop grid-tied systems. Off-grid work is different. It takes real experience with battery sizing, generator integration, pole mounts, and remote property logistics.
SRsolarNH has been doing this for 4 years and handles every step in-house, from initial system design to final commissioning. We built this company on honest service, and it shows in every install.
✔️ Carbon lead and lithium battery storage options sized for your property.
✔️ Generator backup integration for complete reliability.
✔️ Raised pole mount installs when rooftop is not an option.
✔️ Ability to expand existing systems built by another company.
✔️ Voted NH’s #1 solar installer and recognized by EnergySage.

Now is the smart time to install solar alongside your heat pump upgrade. And with $0 down financing through EastRise Credit Union, there is no reason to wait.

A heat pump is a smart, efficient upgrade, but it still runs on electricity you buy from the grid. Adding solar means your new system runs on power you generate on-site, so the upgrade actually shows up on your monthly bill instead of just your comfort. In NH, MA, and ME, where electric rates sit well above the national average, that difference adds up fast.
Off-grid system costs vary based on your energy usage, property size, battery capacity, and whether a generator or a pole mount is included. The best way to get an accurate number is to request a quote so we can assess your actual needs and build a custom proposal.
Yes. SRsolarNH works with existing arrays, including systems originally installed by another company. We can add panels, carbon-lead or lithium batteries, and generators to bring your current setup to full off-grid capability. Just let us know what you have and what you are trying to accomplish.
The timeline depends on the system size and permitting requirements in your town. From your first quote request to full commissioning, most off-grid projects take between 8 and 16 weeks. Permitting, equipment lead times, and site complexity are the main factors. We keep you updated throughout the process so there are no surprises.
Yes, raised pole mounts are one of our specialties. When a roof is not the best option due to orientation, shading, or structural constraints, a ground-mounted or raised pole system positions your panels for maximum sun exposure. We handle the full structural design and installation.
