Let Us Help You



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.

Solar Panels
Your solar panels turn sunlight into clean DC (direct current) electricity.

Solar Inverter
Your solar inverter converts solar generated DC electricity into AC (Alternating Current) electricity that can power your home

Main Electrical Breaker Box
AC electricity passes through your electrical panel to power devices in your home.

Sonnen Eco
Your Sonnen Eco converts excess AC electricity to DC for storage in its battery modules. When you need it, the electricity is converted back to AC—day, night, or during an outage.

Protected Breaker Box
A second breaker box (aka “protected loads panel”) is an additional electrical panel that distributes power to critical devices in your home in an outage from your eco.

Meter
Your meter monitors and measures electricity used by your home and excess solar power fed into the electrical grid.

Utility
Your utility keeps you connected to the local electrical gird, ensuring you have access to grid power when you need it.

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.
Ilum Solar is an expert battery storage system installer.
We can set up a battery storage system as part of a new solar installation, or add a battery storage system to an existing solar system. Our knowledgeable solar battery installers will work with you to determine your energy needs, and can recommend the right battery for your home or business. We can then install the battery storage system in a location that offers ease of use and maximum efficiency.
With Ilum Solar, you can save money on your electric bill and avoid blackouts due to power outages by using the clean, renewable energy stored in your solar battery.
