Innovative MODULAR THERMAL STORAGE
PowerPanel’s Breakthrough Hot & Cold Water Storage System. Quick to install. Customizable design.
Our Thermal Storage:
An Alternative tank solution
Qualifies for Federal & local tax incentives like ITC 40% credit
EFFICIENT
Our tanks carry a 4″ foam wall for optimal thermal insulation. When paired with modern heat pumps, they are 3 to 4 times more efficient than conventional water heating systems.
Made in the USA
competitively priced; domestic sourcing mitigates import tariff risks. Patented.
EASY TO INSTALL
The Thermal Storage Tank is made entirely of engineered, advanced plastics. It’s lightweight and ideal for rooftop installations. You can install it anywhere: on the roof, ground, inside, outside, or even buried.

Not affected by tariffs
Built from materials completely unaffected by current international metal tariffs—insulate yourself and your customers from rising tariff-driven costs.

MODULAR DESIGN
Comes in 3 sizes, ranging from 350 to 700 gallons. No part weighs more than 15 lbs. Use in small areas, no door size is a problem. Scalable, you can use multiple tanks daisy-chained.

COST EFFECTIVE
Especially when used with renewable and “green” sources such as PowerPanel’s own hybrid PV/Thermal panels, reducing or even eliminating the need for utility power. It qualifies for all Federal and local tax incentives including the ITC 40% credit.
DURABLE. NO RUST.
built for the long term—unlike conventional steel tanks the Thermal Tank’s EPP engineered plastic foam construction will never corrode.

Plug-and-play
easy integration into existing boiler configurations, simplifying deployments alongside heat pumps for effective energy storage. Fully configurable. Custom number of heat pumps. No matter of the source of energy.

Success Story: The Bolongo Bay Beach Resort, Virgin Islands
Because the US Virgin Islands struggles with some the highest electricity costs in the USA, the Bolongo Bay Beach Resort there, a 45-room destination hotel, turned to PowerPanel for a solution using hybrid solar thermal-electric generation combined with heat pump technology. PowerPanel’s Gen20 Integrated System now provides enough “net-zero” hot water (in terms of both emissions and costs) to meet the resort’s daily needs.
The company’s patented hybrid Photo- Voltaic/Thermal (PVT) panel array generates both solar electricity and thermal energy to heat water, with 4X the energy output of conventional solar PV alone. To produce enough thermal energy to “power” and supply the necessary 1400 gallons of water stored in PowerPanel’s equally innovative Thermal Storage tanks, the Gen20 heat pumps push additional heat into the system from the warm tropical air outside. The Thermal Tanks themselves also represent a breakthrough in design and materials—they are made from leading-edge, engineered thermoplastics and are safe, durable and recyclable, with none of the weight and corrosion issues associated with conventional steel types, making them practical for rooftop mounting (the resort’s system uses 4 Tanks, 2 on the roof and 2 at ground level).
Because electricity costs are effectively reduced from 0.42 cents per kWh to 0.06 cents, the Made-in-USA system is expected to save the resort about $9,000 annually based on current electricity prices in St. Thomas with Federal and other incentive programs factored in, and achieve a return-on-investment in just over two years. According to the resort’s managing director Richard Doumeng, “PowerPanel really did what they said they were going to do… their system now allows us to have all the hot water we need for our guests and use the sun’s energy to do it, with no additional electricity needed.”

“PowerPanel is taking a different approach: that of combining simple, safe, and easy to manage hot water with advanced thermoplastic technology and architecture—eliminating both the issues with old-fashioned steel tanks and the inherent risks of the newer exotic, inorganic thermal storage schemes… The adaptable materials that form the Tank cover the range of thermal applications, enabling either hot or cold storage from 200°F to as low as -25°F.”
PV Magazine
“The PV generated enables the [PowerPanel] system to function as its own self-contained ‘power plant’ to run the water and heat pumps, heat exchangers, and other devices that comprise a hot water production and delivery system. Such a system can supply an entire commercial facility with enough ‘net zero’ hot water to meet its entire needs.”
