solar, storage, geothermal, and microgrids — designed around your critical loads (and built to operate through outages).
AN ANDXX ENERGY INITIATIVE
save on propane and fuel oil through group buying
Cost stability for fuel-dependent homes and facilities.
Energy independence is possible.
Today.
Tomorrow's solutions. Now.
For homes, businesses, school districts, corporate campuses, industry, and municipalities.
We engineer storage around critical loads so you can operate through outages — no hype, just math.
Multi-source energy + intelligent storage + microgrids sized for the runtime you need. Plus EV integration, community power, and geothermal.
See where you land — no commitment
One clear path: understand first, evaluate next, then design with precision.
These tools help you understand where you currently stand on energy independence — and what level of independence makes sense for your home or facility.
Whether your goal is full independence or reliable coverage for critical loads, the calculators help you see the difference and decide what "enough" really means before moving forward.
In just a few minutes, you'll be able to see:
No commitment. No contact required.
These calculators are built around how homes and facilities actually use power, providing clear, decision-ready insight you can act on.
STEP 2: EVALUATE (when you're ready)
Two tools, one decision. Use the independence calculator to size solar + storage around goals. Use runtime when you're validating outage coverage for known batteries + loads.
Enter your address and monthly kWh from the bill. We estimate solar size, battery needs, and site generation — then compute your scores. Power that's resilient, predictable, and yours.
How much you make yourself.
Backup depends on start charge.
The cost difference between buying energy and producing your own.

Results are calculated using real consumption inputs and regional production modeling.
Ranges are illustrative; final design depends on site, load profile, and utility rules.
Calculate how long your battery system will run during an outage. Input your battery specifications and critical loads to determine precise runtime estimates.
Runtime assumes constant critical load and no solar/grid charging during the outage.
WHO WE SERVE

Single-site and fleet charging — vehicle-to-grid ready.
High-efficiency heating & cooling with stable operating costs.
Campus, district, and industrial resilience at scale.
Uses up to 80% less energy, lasts years longer, and gives brighter, better-quality light.
Keep the system interoperable, optimize intelligently, and unlock EVs as flexible grid assets.
Use EVs as mobile storage — district and campus resilience at scale.
Charge/store/share for lowest cost + highest resilience (hardware dependent).
Designed to work across inverters, meters, and BMS vendors.

Scale capacity
Examples designed for independence and planning. Final design depends on site, load profile, and utility rules.
Solar: 6–12 kW
Battery: 10–20 kWh
Outcome: 70–95% annual independence; essential circuits backed up.
Solar: 250–750 kW
Battery: 250–1000 kWh
Outcome: peak shaving, emergency power hub, fleet charging ready.
Solar: 500 kW–2 MW
Battery: 1–4 MWh
Outcome: demand spikes tamed, outage resilience for critical loads.
Ranges are illustrative; final design depends on site, load profile, and utility rules.
Independence means certainty in a world where the grid delivers uncertainty.

Common questions about energy independence, system sizing, and installation.
No. Enter your address and monthly kWh from your bill—our tool estimates solar and battery size automatically.
Every installation is carried out by licensed engineers and a team of qualified designers and contractors.
They're planning estimates. Final design, pricing, and performance depend on site assessment, permitting, and utility rules.
Homes, businesses, school districts, corporate campuses, municipalities, industrial and warehousing.
We factor incentives/financing during proposal. The calculator focuses on sizing; proposals include payback and options.
The name ANDXX comes from two simple ideas:
'AND' — is a word of inclusion, connection, and progress — and 'X,' the symbol of the unknown.
In mathematics, 'X' begins as the unknown, but once solved, it becomes the solution.
That's why ANDXX carries two X's: the first represents the unknown; the second represents that same X once solved — now the known solution.
