Switching to solar power is a smart way to increase your property’s value, reduce your energy bills, and contribute to a more sustainable world. Thanks to Waipahu’s year-round sunshine, both homes and commercial properties can benefit from solar panels, energy storage systems, and battery installations. At Holu Hou Energy, we’re dedicated to helping our community make the transition to solar simple and effective. We’ve installed solar battery systems in a wide range of buildings — from single-family residences and businesses to multi-dwelling buildings like apartments, condos, and townhomes.
Whether you’re upgrading your current solar configuration or exploring your options for the first time, we’re here to guide you through the process. Our energy solutions are designed to keep your lights on — even when the power grid goes down. Reach out to us today to learn how our advanced solar storage technology can help you take control of your power supply.

Benefits of Solar Storage in Waipahu
Our consistent sunshine isn’t just great for outdoor fun — it’s a powerful resource for generating clean energy. Solar panels can greatly reduce or even eliminate your reliance on conventional energy sources. A properly installed system can generate more power than you use, and with solar batteries and energy storage, you don’t have to send that extra electricity back to the grid for pennies off your bill. Instead, you can store it and use it when needed!
Our energy storage solutions make it easy to access backup power during cloudy days, storms, or power outages. When grid interruptions occur — such as during HECO’s Public Safety Power Shutoff events — stored solar energy can keep your essentials running. With our solar batteries, energy resilience becomes a built-in feature of your home or business.

HoluPower xP Energy Storage System
The HoluPower xP is Hawaii’s exclusive third-generation solar storage system, designed to deliver top performance and safety to your property. We take advantage of high-efficiency lithium-ion technology to store unused solar power at better conversion rates than other solar batteries, ensuring you don’t lose much of your generated power. With this stored energy, you can keep your most important appliances running during outages, high-demand times, and any time you need a little extra power. The system is scalable, too, allowing you to expand with more panels and inverters as your energy demands grow.

HoluPower Smart Panel
Even if your property doesn’t currently have solar, the HoluPower Smart Panel can give you real-time insights into your electricity usage. It transforms your space into a connected energy hub, offering remote control of appliances to improve energy efficiency throughout your property. Paired with the HoluPowerxP solar battery system, it lets you prioritize which devices stay powered in an outage, maximize energy use, and cut energy costs by optimizing your solar usage.

EnergyShare Technology
Shared properties like condos and apartments can now take full advantage of solar thanks to our EnergyShare Technology! Traditional solar systems struggle to evenly distribute power among separate units, but with Holu Hou Energy’s unique technology and solar battery configuration, every unit can access stored power in real time. This approach improves energy sharing, reduces dependence on the utility grid, and makes solar feasible and cost-effective for multi-unit complexes.
