Battery storage systems can decrease electric bills.

Municipal utility companies are switching to
time-of-use pricing, which means customers are charged a varying rate depending on the time of day. Early evening hours, when most people are home and solar panels aren’t generating energy, are when energy rates are the highest. With a home battery system, you can store electricity during the day from your solar power system, or the grid when prices are lower, and use that energy during the evening and avoid peak prices, a cost-saving measure known as “peak shaving.”

You can also save on the upfront cost of a home battery system via the solar investment tax credit, through which you can earn a tax credit equal to 26% of the cost of purchasing and installing a home battery system.

    Solar batteries store
    excess power.

When your energy demands exceed the energy production of your solar panels during the day, or you are using power at night when your panels are no longer generating energy, you can source 100% renewable energy stored in your solar battery to power essential appliances, like refrigerators, microwaves, and lights. In the case of a power outage, you can keep your lights on and important systems operational by sourcing power from your solar battery.

A battery storage system is ideal for reducing your reliance on the electric grid, and can help you save money on monthly electricity costs.

Lithium-ion batteries backed by a manufacturer’s warranty.

We offer three lithium solar batteries: the Sonnen Eco, LG Chem RESU10H, and Enphase Encharge. The Sonnen, LG, and Enphase are small in form factor, but offer a generous amount of storage capacity. Their small footprint means that you can store them in various places around your home without the need for ventilation control, as they do not reach high temperatures like other batteries.

On average, these batteries last ten or more years before replacement. Both models also come with a ten-year warranty.

Frequently Asked Questions

on home and business battery storage systems

Where can battery storage systems be installed?

Batteries may be installed in garages, sheds, or even inside your home or business. An Ilum Solar representative can help you determine where best to install your battery storage system.

Do you offer a battery storage system warranty?

Each battery is backed by a 10-year manufacturer’s warranty. In the case that your battery malfunctions or fails to operate as guaranteed, the manufacturer will supply a new one.

How long does it take to install a battery system?

Typical installations take 1-3 days.

Can I power my home or business with a battery storage system during a power outage?

Solar batteries have limited storage capacity, meaning that they can only power your entire home or business for a few hours at most, and aren’t appropriate for powering HVAC systems and other extremely energy-intensive systems. 

A battery storage system is ideal for powering essential systems during a power outage, such as a refrigerator, microwave, or lights. These systems require only a small amount of electricity, so your battery storage system can meet their energy demands for several days.

Do you offer technical and equipment support?

Yes! Ilum Solar installation experts and customer service agents can offer technical and equipment support to help you get the most out of your battery storage system.

Do you offer regular system maintenance?

Yes. Ilum Solar technicians are certified to work with Sonnen, LG, and Enphase batteries.

Do you offer purchase and/or lease financing options?

We offer purchase and lease options, and can help you determine the best financing for you.

Will a battery storage system increase my insurance premiums?

You may be required to purchase more coverage for your home or business when you install a solar battery. Contact your insurance provider to learn more.

Can I purchase a solar battery system and install it myself?

Due to system complexity, only a trained technician should install your battery storage system.

When the battery reaches the end of its lifespan, can I safely recycle it?

California has an electronic waste management program which accepts lithium-ion batteries. Contact your local e-waste location to learn more.

Customer Stories

There are few companies that I would rate 5 stars.
Ilum Solar is one of them.

As a retired electrical engineer and home owner I carefully monitored the workers during the installation and the finished product. The workers were very friendly and did not appear to be bothered by my monitoring them. I could not be more pleased with the quality and care of the installation..

It was so easy to work with Ilum Solar.

Of all the local solar companies we talked to, Ilum Solar was the most honest, fair, and professional. They were able to work with us on financing, and made sure we got the right solar system for our home. They really went above and beyond – the entire process was quick and easy, and I’d recommend Ilum to anyone wanting solar!
