SOLAR BATTERIES

At SunnyMac, we empower homeowners across Delaware, Maryland, Pennsylvania, and New Jersey to take control of their energy usage with advanced solar batteries. Whether you’re looking for a whole house battery backup to prepare for outages or a house battery backup system to reduce your reliance on the grid, our solutions deliver stability, independence, and real savings.

By integrating solar panels with high efficiency batteries, you can store unused solar power for nighttime use, emergencies, or even sell it back to the grid (in select areas, contact us for more details). Combined with incentives and long battery lifespans, this is one of the smartest investments homeowners can make toward energy independence.

Solar Battery Rebates

Solar battery systems are more affordable than ever, thanks to generous local and federal incentives:

Federal Tax Credit: homeowners can claim 30% of the cost (equipment and installation) through federal Investment Tax Credit (ITC).
State-Level Benefits:
- Maryland and New Jersey offer sales tax exemptions on solar and storage equipment.
- In these states, solar batteries don’t increase your property taxes, even though they add home value.
Potential Grid-Sharing Income: while programs are still emerging, some states are exploring grid-sharing initiatives, where homeowners may be paid for discharging stored solar energy during peak demand. We’re watching these developments closely and will guide eligible customers as new opportunities arise.

Frequently Asked Questions

How does a solar battery work?

A solar battery stores excess electricity generated by your solar panels. Instead of sending unused energy back to the grid, it’s saved for later use, especially at night or during power outages. This makes your home more self-sufficient and reduces dependence on your utility provider.

How long do solar batteries last?

According to a study by the Lawrence Berkeley National Laboratory, modern lithium-ion solar batteries last approximately 10 to 15 years, depending on use, environment, and maintenance. Most come with warranties up to 10 years, ensuring dependable long-term performance.

Can I add a solar battery to my existing solar system?

Yes! Many homeowners choose to add battery backup to their current solar array. SunnyMac evaluates your system and configures a compatible solution, allowing you to gain the benefits of energy storage without starting from scratch.

How much energy can a solar battery store?

Storage capacity varies by model but most residential batteries hold between 10 to 20 kilowatt-hours (kWh). That’s enough to power essentials like lights, fridge, Wi-Fi, and basic appliances for several hours, or even an entire day, depending on usage.

What type of solar batteries are there?

The most common types are lithium-ion batteries, known for their high efficiency, long lifespan, and compact design. We install leading models from SolarEdge, Enphase and other top manufacturers, all chosen for reliability, safety, and smart-home compatibility.
