The new solar policy is a game-changer.
Right-sizing your system is key.
Don’t buy more PV than you need or waste the power you generate.
Knowing the PV system size your family needs is a big deal. With the recent changes to solar interconnection, it is more important than ever. Purchasing an oversized system for your home can cost you thousands for extra panels, and even more when excess energy goes unused. Undersized systems aren’t a good deal either—the low cost is appealing, but the low solar production will disappoint you. How can you find that perfect fit? KumuKit™ systems have always been Right-Sized, but now, our new PV SIZER™ tool can help you visualize the system size you’ll need, and better understand how to maximize it’s power.
Return on Investment
Enjoy a lifetime return on your investment.
At 7.5% to 9%+ annual return, solar consistently outperforms all other conventional investments. KumuKit™ systems still typically have the strongest return on investment in the industry.
“With the new grid credit, the rate of return is between 7.5% and 9%, depending on the utility...My 401(k) is not getting 7.5%. Nobody’s is.”

KumuKit™2.0—New Version. New Vision.
Our goal has always been simple, to provide affordable energy solutions that promote and accelerate the adoption of clean renewable energy. Recently, the utility raised concerns about grid penetration, stability and safety, slowing solar installations until the situation could be fully studied, leaving the path forward in question. Many saw a problem and gave up on solar, but we decided instead, to be part of the solution. After listening to discussion about what couldn’t be done, we decided to imagine, research and implement what could be done to meet the needs of these two very diverse groups—homeowners who want rooftop solar and a utility concerned for the grid. With this new vision in mind, our team at Hawaii Energy Connection worked with our vendors to develop KumuKit™2.0, our next-generation PV system. Our goal was to address these primary concerns: system visibility for the homeowner, grid visibility for the utility, and smooth delivery of stable power to the grid, with the ability to adapt to changes in solar energy policy. Then we added one more goal: develop a concept for the future, but find a solution within reach today. We envisioned cutting-edge technology to address grid issues, allowing more households and small businesses to adopt solar and be grid-integrated as a welcomed clean energy source for everyone. An all inclusive solution, with a way to upgrade first generation KumuKit™ systems and other PV systems, too. Growing a community of distributed rooftop solar into a powerful alternative to imported oil, liquefied gas from fracking, or massive solar farms at the expense of green space.
Smart Energy Management Welcome to the way forward—KumuKit™2.0 now with Smart Energy Management. When you enhance a PV system with Smart Energy Management, you get optimized energy production + optimized energy usage. System visibility is achieved through secure cloud-based tools with an intuitive Energy Dashboard interface that makes it easy to manage select home loads with real-time visibility and historical reporting capability. You can shift time-of-use costs to your best advantage, see where energy is being consumed, identify electricity hogs, set electricity reduction and savings goals, and monitor your progress. Adaptability and responsiveness to the grid are accomplished with our Smart Energy Management Controller. Compatible with most PV technology—old or new, micro or string inverters, including management of compliant smart PV systems. It can adapt to future utility requirements, address changing home and grid conditions, maximize production and optimize overall energy efficiency. A breakthrough in distributed energy resource management—our Smart Storage option enhances a PV system’s abilities and allows you to store your own PV energy. The modular design allows for easy upgrade and incremental expansion. The automatic emergency backup power feature provides for critical loads such as lighting, medical equipment, refrigerators, phone chargers, etc. during an outage. Smart Storage can also buffer, smooth out and stabilize the energy you want transferred back to the grid.
Your power. Your way. Take charge of the solar power you generate. Make your home a powerhouse with a PV system designed to be simple, intelligent, adaptive, interconnected, monitored, controlled, and gridwise—KumuKit 2.0 is the way forward.
Smart Energy Management
Utilities around the world are rapidly moving away from simple electrical generation and distribution models to more intelligent and dynamic energy management systems. As technologies evolve so will the relationship between rooftop PV owners and their utilities. Grid connected energy producers will become essential partners able to share the benefits of a smarter interactive grid. Smart Energy Management has the ability to leverage a PV system’s production to your advantage by automatically optimizing energy generation, usage and smart export. A secure cloud-based dashboard and toolset provide real-time PV energy generation and home usage visibility, putting easy home load monitoring and control at your fingertips. Simple and automated control of your energy means you can take advantage of all utility and grid support benefits.
Modular in design, and scalable, optional Smart Storage increases your PV system’s effectiveness by allowing both smart energy export or non-export/self consumption between specific times each day. Additional benefits include emergency backup for important loads such as lighting, medical equipment and refrigeration when needed. An intelligent system that will provide benefits now, adapting to changing needs, grid challenges, Utility benefits and evolving solar energy policy—essentially future-proofing your PV system. Imagine a community of rooftop PV systems upgraded with Smart Energy Management technology. Each maximizing customer savings, improving our grid, providing greater renewable energy interconnection—reducing reliance on imported oil, liquefied gas from fracking and saving precious green space from massive solar farms.
The average household consumes only 20-30% of PV energy generated within solar production hours. During peak solar production the excess energy sent to the grid by thousands of net-metered systems introduces instability and additional challenges to the grid. Smart Energy Management leverages Smart Storage to capture the excess PV production that is typically exported during the day.
The stored energy can later be smoothly exported to the grid when most advantageous, or used directly in your home instead of drawing energy from the grid during peak demand hours. It can also be used as your emergency reserve for critical loads during a power outage.
