Energy Independence — Solar, Storage & Whole-Home Backup in New Hampshire

What we do

We build the power. You decide how far it goes.

Energy independence is a direction, not a single purchase. We build the foundation — the generation, the storage and the transfer that makes your house able to stand on its own. Every electric thing you add after that runs on power you already own.

01

Produce your own power

An array engineered for December, not for a good day in June — sized for what you actually need, and built out to whatever you want. Roof, ground mount or pole, with the service work to carry it.

02

Store your own power

Batteries, inverter controls and wireless monitoring, so what the array produced at noon you can still use at midnight — and it keeps producing with the utility down instead of shutting off. This is where the grid becomes optional.

03 · and it doesn't stop there

Take it as far as you want

Independence isn't one purchase. Heat, hot water, cooking, an EV in the driveway — the more of them you move onto electricity, the more your own power saves you. We keep adding generation and storage to match, so the supply always stays ahead of the load. Start with keeping the lights on; end up off the fuel truck entirely.

Let's talk about the real savings

The bills that leave for good.

Not paying for electricity is the easy part. The real money is the oil or propane you stop having delivered every winter, and the gasoline you stop buying every week once the car charges at home. Those aren't discounts. They're bills that leave your house and don't come back. The equipment exists today, so the only question left is how early you start and how far ahead you want to be.

and it grows as fuel does

Example — a 2,000 sq ft home burning 900 gallons of oil a year at $4.90, fully electrified, with an array sized to cover the whole house. The house draws about 18,000 kWh a year; a 15.5 kW array makes about that much, so nothing is bought and all that's left is the utility's standing charge for staying connected. It counts heat, hot water and cooking, not the gasoline you'd stop buying. Your house is not that house, and the appliance side is its own project with its own cost. Every number here is a slider on the calculator, including the ones that make the answer smaller.

Run your own numbers

Where you start

Two ways in. Same destination.

Most people find us from one of two places. The system we design looks different depending on which one you're in — the goal doesn't.

Already making power. Now keep it.

You already have solar

You're halfway there already

Right now your array sends everything it makes straight to the grid, and every kilowatt-hour you use after sundown you buy back. Storage closes that loop — the power your roof made at noon is still yours at midnight, and it's still yours when the utility drops. Same panels, doing considerably more work.

Keep what you generate — batteries hold the midday surplus instead of exporting it
Stay on through an outage — switching gear cuts the house loose from the road so the array can run it with the grid down, which a plain grid-tied setup can't do
Use the equipment you own — AC-coupling or an inverter swap, whichever is cheaper for your gear
Prioritise what matters — a backup loads panel that carries water, heat and refrigeration first
Size it for winter — more capacity if December production can't refill the bank

Line crews en route. Nobody here is waiting.

You have no solar yet

Start anywhere. Build from there.

You don't need an array to start owning your power. Storage and transfer come first and solve the outage problem on their own; generation goes on the roof whenever you're ready. Nothing gets torn out and redone later.

Backup without an array — whole-home or critical-loads storage, working from day one
Room to grow — service and panel upgrades sized for the system you'll end up with
Your generator, smarter — integrated and switched automatically instead of run all night
Solar-ready — pre-wired and permitted for an array in year two or year five
Off-grid builds — camps, barns and lots the utility never reached

The bonus that sells itself

Set the bank. See how long you last.

The savings are why the system pays for itself. This is why you’ll be glad you have it. Size the bank below, then open the panel and switch on what you’d actually need during an outage.

Battery bank 30 kWh

Most New Hampshire homes land between 20 and 40 kWh. Larger banks are for long outages or running the whole house.

Solar recharging the bank None

How it works →

How it goes

Four steps. No surprises at step three.

01

Site assessment

We walk the property, open the panel, read your last twelve months of usage and ask what you actually can't live without. Roughly ninety minutes, and you get the numbers whether or not you hire us.

02

Design & fixed proposal

A single-line diagram, a sized bank, a runtime figure tied to your loads, and a price that doesn't move. We walk through the incentives that are actually available the week you sign.

03

Permits & interconnection

Town electrical permit, inspection scheduling and the utility interconnection paperwork. We file it, we chase it, and we tell you where it is without being asked.

04

Install, finalize, hand off

We build it, then we deliberately kill the grid feed and watch the house carry over while you're standing there. You leave knowing how to read the app and what to do if something trips.

Optional, before step 01

A load study

If you’d rather have hard numbers than an estimate, we can fit a monitor in your panel and leave it thirty to sixty days. It logs every circuit through a cold snap, and you get a written report of what your house actually draws and what a battery would have to carry. Flat fee, credited against the install if you go ahead.

Optional, after step 04

An annual health check

Storage and inverters are not fit-and-forget. Once a year we check terminations and torque, look for heat where there shouldn’t be any, update firmware and test what the bank actually holds against what it held when it was new. Book one whenever you like — ours or anyone else’s. If somebody installed your system and stopped returning calls, bring it to us anyway.

Built for here

A system designed in Arizona will let you down in February.

New Hampshire outages aren't four hours in mild weather. They're three days, in an ice storm, on a road the crews get to last. That changes what you build.

Water is the first thing you lose
On a well and septic, an outage means no water and no drains within hours. The well pump and any effluent pump come before the television in every design we do.
Heat is an electrical load, even when it's oil
Oil and propane boilers still need the circulator and controls. A modest battery keeps a whole heating system alive; it's the cheapest freeze protection you can buy.
December production is a fraction of June
We size against the worst month, not the average. Short days, low sun angle and snow on the array are all in the model before you sign anything.
Batteries don't like unconditioned barns
Siting and thermal management get decided on the walkthrough. Cold cells lose capacity exactly when you need it.
Long outages need a third leg
Battery plus solar covers most events. For the week-long ones, a generator that starts only when the bank runs low is the difference between comfortable and camping.

Straight answers

Questions we get every week.

Can I go fully off-grid at my house?

Sometimes, and we'll tell you honestly if yours isn't a good candidate. Full independence needs generation, storage and usually a generator sized for a stretch of bad weather — which is a bigger system than most homes need. Many customers land on "near-independent": grid-connected, but able to run for days without it. We price both so you can see the gap.

Why don't my existing solar panels work in an outage?

Safety. A standard grid-tied inverter is required to shut down when the utility goes down, so line workers aren't dealing with a live wire from your roof. Adding storage plus the right switching gear changes that: the moment the grid fails your house is cut loose from the road, and the array keeps running the house instead of feeding the line. Nothing goes back out, so the crews stay safe and you stay on.

Do I have to back up the whole house?

No, and it's often the wrong first move. A critical-loads panel covering water, heat, refrigeration, lights and internet costs a fraction of whole-home and covers ninety percent of what an outage actually takes from you. We design so you can expand to whole-home later without redoing the work.

What about incentives and tax credits?

Federal and state-level programs for storage change, and some have expiration dates attached. We won't quote you a percentage off a website — at the proposal we walk through exactly what's available for your system that month, what you have to file, and what the price looks like if you assume none of it comes through.

Will this work with the generator I already own?

Usually yes. A battery and an existing generator work well together: the battery handles the short, frequent outages silently, and the generator only fires for the long ones. We integrate what you have rather than selling you a replacement.

How long does a project take?

Typical storage retrofits run a couple of days on site. The calendar is usually driven by equipment lead times, town permitting and utility interconnection review, not by the labor. We give you a date range at the proposal and update it when it moves.
