You can still save big on your electric bill. Under the current customer self-supply solar program, a homeowner cannot send excess solar to the grid, but can still draw power from the grid. Today, you’re hearing more and more about batteries and energy storage systems. But did you know that not all battery or energy storage systems are alike?

So much more than just batteries, the KumuKit Powerblocks™ system connects to new and existing photovoltaic (PV) systems, and works together with your solar panels and household electrical devices, allowing you to manage your energy using an Energy Management Controller (EMC). In fact, all newly installed KumuKit™ PV systems come with this innovative and proprietary EMC, creating a PV energy management system unlike any other in Hawaii or rather on the market today.



Hawaii Energy Connection’s self-supply systems can start at $5,000 after the still-generous state and federal tax credits, and cover roughly 30 percent of a home’s energy demand. Customers can add batteries later to increase the system size if they want.

The total upfront costs, before the tax credits, range from $14,000 (without batteries) to upward of $35,000 (with batteries). In 2008, at the beginning of Hawaii’s PV solar boom, the cost of PV alone is the same price as PV with energy storage today.

Power outages from tropical storms and electrical grid failure are inevitable. Keep the power flowing and your family going with Power-blocks,™ and you won’t have to suffer through them again . Power-blocks™ operates silently in the background, providing immediate back-up power to lighting, medical equipment, refrigerator, television, radio, phone chargers, fish tank/pond or other critical items that are important to your family in times of emergency.


KumuKit™ has fantastic financing options available, too. Many of you already have Net Energy Metering (NEM) or Customer Grid-Supply (CGS) approvals to install a PV system, but are unable to contact your original contractor or they’re longer in business.

Give Hawaii Energy Connection a call and the staff will help you continue through the process to get you installed. Last month, the company offered free educational seminars at our facility, which were well attended and will continue again in January after the holidays.

Every family is unique with their home electricity usage, so knowing the PV system size you will need is a big deal. With the company’s exclusive PV SIZER™ tool, allow the company to help you to “right-size” a system, visualize the system size you’ll need, and better understand how to maximize its power.
