Home Battery Storage
Tesla Powerwall & Battery Storage in Binghamton, NY
The Southern Tier averages 2–3 power outages per year from ice storms, high winds, and grid failures. A Tesla Powerwall or battery storage system keeps your lights on, your sump pump running, and your family comfortable when the grid goes down.
Home Battery Storage for Energy Independence
Battery storage transforms your solar system from a daytime-only investment into true energy independence. A single Tesla Powerwall stores 13.5 kWh of energy — enough to power most homes through an overnight outage or several hours of heavy use during a grid failure.
In the Southern Tier, battery storage isn’t a luxury — it’s insurance. Our winters bring ice storms that can knock out power for days. Sump pumps, refrigerators, medical equipment, and heating systems all need power when the grid fails. A Powerwall detects the outage and switches to battery power in milliseconds.
Battery storage also maximizes your solar investment through time-of-use optimization. Store excess solar production during the day and use it during peak evening hours when grid electricity costs more. Some utility programs offer additional credits for battery-equipped homes.
We offer the full Powerwall lineup including the Powerwall 3 with integrated inverter. We also install Enphase, Generac, and other battery systems based on your specific needs and budget.
Why Add Battery Storage
Backup Power
Seamless backup during grid outages — your Powerwall detects the outage and switches in milliseconds.
Solar Self-Consumption
Store excess solar production for nighttime use instead of sending it back to the grid at low credit rates.
Energy Arbitrage
Charge from solar during the day, use stored energy during expensive peak hours to maximize savings.

We analyze your energy usage patterns and identify which loads are critical during an outage to size the right system.
-
Design & Install
We design the battery system to integrate with your existing or new solar array and install it in a single day.
-
Configure & Monitor
We configure your backup circuits, set up the Tesla app, and show you how to monitor and manage your system.
Frequently Asked Questions
How much does a Tesla Powerwall cost?
A single Powerwall typically costs $12,000–$15,000 installed. Many homes benefit from two Powerwalls for extended backup capability.
How long will a Powerwall last during an outage?
A single Powerwall (13.5 kWh) can power essential loads (lights, fridge, internet, sump pump) for 12–24+ hours depending on usage. With solar panels, your battery recharges daily, giving you indefinite backup during extended outages.
Can I add a Powerwall to my existing solar system?
Yes. Powerwalls can be retrofitted to existing solar installations. We’ll evaluate your current system and design the optimal integration. The Powerwall 3 includes an integrated inverter that simplifies retrofits.
What’s the warranty?
Tesla Powerwall comes with a 10-year warranty guaranteeing 70% capacity retention. In practice, most Powerwalls retain 80%+ capacity for 15+ years.
