SunPol Solar installs FranklinWH aPower 2 home battery systems for Connecticut homeowners, pairing with new or existing solar panels to provide backup power during grid outages. Battery storage keeps essential loads — fridge, lights, Wi-Fi, medical equipment — powered when the grid goes down. Available as an add-on to any SunPol solar installation.
The Grid Problem
Connecticut homeowners experienced over 1,200 power outages in 2024 alone. When the grid goes down, your solar panels shut off too — unless you have battery backup. A home battery system stores your excess solar energy and deploys it the moment you need it: during storms, grid failures, or peak pricing hours when electricity costs the most.
Why Battery Storage?
Three Reasons Every Solar Home Needs a Battery
Solar panels generate power during the day, but your home uses the most energy in the evening. Battery storage bridges that gap — and does much more.

Backup Power When You Need It
When the grid goes down, your battery kicks in instantly. Keep your lights, fridge, medical equipment, and home office running — no generator noise, no fuel, no hassle.
Maximum Savings
Store excess solar energy during the day and use it at night or during peak pricing hours. Avoid the most expensive electricity rates and keep more money in your pocket.
Energy Independence
Reduce your dependence on the grid and take full control of when and how you use your energy. With battery + solar, you’re producing, storing, and using your own clean power.

The Smart Upgrade
Solar + Battery vs. Solar Only
See why adding battery storage transforms your solar investment from good to bulletproof.
Full control. Full backup.
- Power stays on during grid outages
- Store excess solar for nighttime use
- Avoid peak electricity pricing
- True energy independence from the grid
- Silent operation — no fuel, no noise
Still grid-dependent.
- Solar shuts off during grid outages
- Excess energy sent to the grid, not stored
- Still pay peak rates in the evening
- No backup during storms or emergencies
- Dependent on utility net metering policies
- May need a gas generator for emergencies
| Feature | Solar + Battery | Solar Only |
|---|---|---|
| Power during outages | Yes — battery keeps essentials running | No — solar shuts off with the grid |
| Nighttime energy use | Uses stored solar energy | Draws from grid at full rate |
| Peak rate avoidance | Yes — battery discharges during 4–9 PM | No — pays peak utility rates |
| Energy independence | Near-complete with right sizing | Still grid-dependent |
| Emergency backup | Silent, automatic, fuel-free | Requires gas generator |
| Excess solar energy | Stored for later use | Sent to grid for credits |
What Gets Backed Up?

Is This You?
Which Connecticut Homeowners Need Battery Storage?
Existing Solar Homeowner
You already have solar panels but no backup. Add a battery to store your own energy, avoid peak rates, and finally have power during outages.
New Solar + Battery
Going solar for the first time? Bundle battery storage from day one. One installation, one crew, one optimized system designed together.
Storm-Prone Area
If you’ve lost power more than once in the last year, a battery system pays for itself in peace of mind alone. Connecticut weather isn’t getting calmer.
Key Terms
Battery Storage Terminology
- Home Battery System
- A rechargeable lithium-ion battery installed in your home that stores energy from your solar panels or the grid. It deploys that stored energy during outages, at night, or during peak pricing hours.
- Peak Shaving
- Using your stored battery energy during the hours when grid electricity is most expensive (typically 4–9 PM in Connecticut). This avoids the highest rates and maximizes your solar savings.
- Solar Generator
- A portable or whole-home battery system paired with solar panels that generates and stores clean energy. Unlike gas generators, solar generators produce no emissions, no noise, and require no fuel.
Our Vision
A future where families are no longer defined by the rising cost of power, but empowered by smarter energy choices that create greater freedom, stronger financial security, and more time for what matters most.
Common Questions
Battery Storage FAQ
How much does a home battery system cost in Connecticut?
A typical home battery system costs between $10,000–$18,000. SunPol offers $0-down financing options. We provide a clear, itemized quote after reviewing your energy needs.
How long can a battery power my home during an outage?
With a standard home battery (10–13.5 kWh), you can power essential circuits for 8–12 hours during an outage. With solar panels recharging the battery during the day, you can extend backup indefinitely for essential loads. System sizing depends on your priorities.
Can I add a battery to my existing solar system?
Yes. SunPol retrofits battery storage onto existing solar systems across Connecticut, regardless of who installed your panels. We’ll assess your current system and design a battery solution that integrates seamlessly.
What brands of batteries do you install?
We install the FranklinWH aPower 2 battery system. Our team recommends the best fit based on your home’s needs, your existing solar system, and your budget.
How long does installation take?
A typical battery installation takes 1 day. Permitting and utility coordination may add 2–4 weeks to the overall timeline, but SunPol handles all of that for you. From consultation to activation, expect 4–8 weeks total.
Do I need solar panels to get a battery?
No — a battery can be installed as a standalone backup system that charges from the grid. However, pairing with solar panels maximizes your savings and gives you true energy independence. Most homeowners choose the solar + battery combination.
How long do home batteries last?
Modern lithium-ion home batteries are warrantied for 10–15 years and typically last well beyond that. They require zero maintenance. Your battery will continue to deliver reliable performance throughout its lifespan.
