Frequently Asked Questions: Solar Batteries

Get answers to common questions about solar batteries, their benefits,
and how they can enhance your energy efficiency and independence.

Why should I add a battery to my solar system?

Infinity Energy recommends pairing solar panels with a battery like the Tesla Powerwall for maximum control, savings, and resilience. While solar alone can lower your utility bill, adding a battery allows you to store and use your energy on your terms—not the utility’s.

Here’s what you gain with a solar battery:

Keep essential appliances running even during a grid outage, including your refrigerator, lighting, internet, and more.
Use more of your solar energy by storing it for nights and cloudy days.
Avoid peak electricity rates by drawing from stored energy instead of the grid.
Cut ties with unpredictable energy markets and enjoy true energy independence.
Boost your property value with a modern, self-sufficient energy system.
Qualify for tax credits and local rebates that lower installation costs.

Do I need solar panels to use a solar battery?

No, a solar battery like the Tesla Powerwall can be charged directly from the grid, though it’s most effective when paired with solar panels.

This is great news for homeowners who do not own solar panels, but are looking for an energy storage alternative to a gas-powered generator. Tesla Powerwalls are cleaner, quieter, and require less maintenance than gas generators do, making them a fantastic alternative. No more fuel, fumes, or noise!

How long will a solar battery power my home?

It depends on how much energy your home uses and the size of your battery system. A single Tesla Powerwall can typically power essential appliances for 12–24 hours. With multiple Powerwalls or energy-efficient usage, some homes can extend this window by hours or even days.

Throw the traditional refueling idea out the window. With solar panels, your battery will charge automatically with power straight from the sun.

Frequently Asked Questions: Tesla Powerwall

How much energy can a Tesla Powerwall store?

The Tesla Powerwall 2 and Powerwall+ each store 13.5 kWh of usable energy, which is typically enough to power essentials like your refrigerator, lights, Wi-Fi, and medical devices overnight or during an outage. The Powerwall+ includes an integrated solar inverter, which offers greater efficiency for homes with solar panels.

If your energy needs exceed that capacity, you can combine two or more Powerwalls for greater energy storage. Up to 10 Powerwalls can be stacked in a single system, providing as much as 135 kWh of total storage—ideal for larger homes or commercial properties needing more backup power or energy independence.

Can the Tesla Powerwall provide backup power during a grid outage?

Yes, the Powerwall detects outages instantly and switches to battery power within a fraction of a second—so fast you won’t even notice the grid went down. It keeps your critical appliances running and can be customized to prioritize what gets powered, whether it’s your lights, refrigerator, HVAC system, or entire home.

How long does a Tesla Powerwall last?

Tesla backs the Powerwall with a 10-year warranty that guarantees at least 70% of its capacity remains after a decade of use. Most Powerwalls last between 10 and 15 years, depending on your daily energy usage, weather conditions, and how often you charge and discharge the battery.

What can the Tesla app do for Powerwall users?

The Tesla app gives you real-time control and visibility over your solar battery system, and it’s included with your Powerwall installation.

With the Tesla app, you can:

Monitor energy usage in real time
Track solar production (if you have panels) and how much energy you’re generating
View battery status, including current charge level and usage history
Set operating modes like Backup-Only, Self-Powered, or Time-Based Control
Receive storm alerts so you can fully charge your Powerwall ahead of potential outages
Optimize energy savings by adjusting how and when stored power is used

Frequently Asked Questions: Solar Batteries in Connecticut

Are there state incentives for installing a Tesla Powerwall in Connecticut?

Yes. Connecticut offers generous incentives through the Energy Storage Solutions (ESS) program, which is designed to encourage the adoption of battery storage for both homes and businesses. The program provides:

Upfront incentives to lower the initial installation cost
Performance-based incentives that pay out over time based on how your battery performs, especially during times of grid stress
Additional benefits for low-income customers, critical facilities, and those in vulnerable communities

These incentives are managed by the Connecticut Green Bank in partnership with the state’s major utilities, and they make it much more affordable to add a Tesla Powerwall to your energy system. If you’re not sure where to start, don’t worry. Infinity Energy will walk you through the application process.

Do I need a permit to install a solar battery in Connecticut?

The Tesla Powerwall requires both electrical and building permits, depending on the local jurisdiction. The good news is Infinity Energy takes care of it all for you. Our team works with your local municipality to handle the paperwork, inspections, and approvals.

Can a solar battery help me during winter storms or hurricanes in Connecticut?

Snowstorms, hurricanes, and high winds are the main source of grid outages. A Tesla Powerwall provides reliable backup power that automatically switches on within a fraction of a second when the grid goes down.

With a solar battery in place, you can keep critical systems like refrigeration, heating, lighting, medical equipment, and internet running even during extended outages. For homeowners and businesses that can’t afford downtime, a Powerwall offers peace of mind and energy security year-round.

Is my home or business eligible for battery storage?

In most cases, yes. And if you are not completely sure, Infinity Energy offers free evaluations to determine whether a solar battery makes sense for your home and local area.

Infinity Energy will assess factors like your existing electrical infrastructure, space for the battery, backup power needs, and potential savings from incentives. From there, we’ll design a solution that fits your home or commercial property perfectly.
