Reach out to us today to discover more about our solar storage systems.

How Solar Storage Works
Typical solar systems and those without adequate energy storage generate energy from sunlight hitting your panels, which then feeds directly into your home’s electricity needs. Any excess or unused power is either wasted or sold back to the Hawaiian Electric Company (HECO) at a discounted rate. Plus, your home reverts back to power from the electrical grid whenever the sun isn’t shining, whether it’s a cloudy day or the middle of the night.
Battery storage offers a smart way to capture and hold onto the extra power your solar panels generate during peak sunlight hours. When your system produces more electricity than your property is currently using, that surplus energy is directed into our high-efficiency lithium-ion batteries for later use.
With stored energy on hand, you can continue to power your home even after the sun goes down or during overcast weather. Rather than letting that clean energy go to waste, Holu Hou Energy’s solar energy storage solutions help you maximize your solar investment while cutting down on utility costs.

Benefits of Solar Storage in Aiea
Many parts of life benefit from the near-constant sunny weather in Aiea — the lush greenery, the outdoor activities, and your property’s solar system! Solar panels help us take advantage of the abundance of renewable energy available in our community and reduce our dependence on less-efficient fuel sources. With a properly sized solar array, the sun could meet and exceed all of your energy needs! Upgrade your solar panels and energy system with residential energy storage and take advantage of the many benefits, such as:
- Reduced Energy Bills
- Energy Buy-Back Programs
- Greater Independence from the Grid
- Power Outage Safety Net
Our solar batteries make great additions to any solar array in Aiea, allowing you to use your stored energy whenever the sun isn’t shining. Between cloudy days, storms, and power outages, you deserve the peace of mind that comes with always having the energy for your essentials.
Reduce Your Reliance on HECO
Like any municipal power company, HECO is responsible for ensuring all customers have access to reliable electricity. HECO’s prices for electricity fluctuate based on usage, property type, and even the time of day to continue supplying the power that Oahu families and businesses need.
Making matters worse, power on Oahu is more expensive than most other locations due to the added cost of importing oil to the islands. New “effective rates” are submitted each month that adjust prices, meaning customers can never be certain how much their energy will cost in the future. Plus, severe weather and emergency precautions like HECO’s Public Safety Power Shutoff program mean you could suddenly be without power for an extended period of time.
Solar energy and our solar battery systems solve these problems! By capturing more of the energy produced by your solar panels, your solar energy storage helps you cut back on the electricity you need from HECO. You’ll save money on your energy bill, always have the energy you need on your property, and also help reduce Oahu’s overall dependence on oil, helping advance our goal of 100% clean energy use by the year 2045.

EnergyShare Technology
Aiea’s multi-dwelling unit (MDU) properties now have an innovative solution for adopting solar energy! Previously, there was no way to manage the energy consumption of individual units while maximizing the solar energy generated for the entire property. With our HoluPower xP Energy Storage System featuring EnergyShare Technology, MDUs can distribute energy among units in a cluster and tap into excess energy from the shared solar system in real-time. This technology leads to more efficient energy use for MDU complexes, significantly reduces their reliance on utility providers, and makes solar energy more viable and cost-effective.
