POWER WITH PURPOSE

SunDrum® reduces emissions, generates cost-effective savings, and supports energy independence for businesses and individuals with high heating demand, including industrial, commercial, and residential applications.

Brewery | Kihei, HI

220 Collectors | 53,000 therms per year

System generates simultaneous hot (160°F) and chilled (40°F) water for brewery processes at industry-leading efficiency.

Hotel | Bakersfield, CA

42 Collectors | 2,400 therms per year

Small hotel qualified for a low-interest-rate SB504 loan (15% emissions offset) with a hybrid solar system that fit on limited roof space. System reached 100% project payback within 4 years.

Apartment | San Francisco, CA

34 Collectors | 2,400 therms per year

SunDrum® Collectors mounted under an existing PV array to provide 24/7/365 space and water heating for a large multifamily complex.

Military Barracks | North Chicago, IL

1,300 Collectors | 65,000 therms per year

System provided dormitory and laundry hot water heating for six dormitories and a central laundry facility at a large military barracks.

Net Zero Home | Washington, D.C.

32 Collectors | 2,490 therms per year

Association of Energy Engineers 2017 Innovative Energy Project of the Year Award

Solar hybrid solution offset 91% of annual heating load and 95% of cooling load, toward a “Net Zero Home” project.

Community Center and Pool | Palo Alto, CA

120 Collectors | 13,000 therms per year

Carport array mounted under existing PV panels offset nearly 100% of pool and water heating demand in a large community center.

Hotel | Maui, HI

40 Collectors | 1,900 therms per year

Small hotel offset 31 tonnes of CO2e annually (and the majority of pool and water heating demand) with only 1,000 sqft of available roof space.

Hotel | Augusta, GA

40 Collectors

System mounted under an existing PV array to meet hotel hot water needs; integrated heat pump used to generate 140°F hot water at high efficiencies.

Hotel | Wahiawa, HI

282 Collectors

Large SunDrum® system led to $7,500/mo in energy savings, 2.5 years to project breakeven, and $1.1 million in expected project lifetime value.

University Pool | Providence, RI

168 Collectors

University aquatics center added SunDrum® Collectors as part of a new PV project to provide on-demand and standby pool heating year-round.

Office | Boston, MA

110 Collectors

Large hybrid solar array installed atop a federal building; 29,000 kg of CO2e emissions offset annually.

SUNDRUM COLLECTORS

The award-winning, patented SunDrum Collector mounts behind PV panels, cooling the panels and sending captured heat to an integrated heat pump.

INTRODUCING HARVESTHP®

HarvestHP Technology provides 24/7 heating across a range of applications.
When the sun is bright, Active Mode captures solar electric and thermal energy.
When the sun is dim or unavailable, Harvest Mode uses the heat pump to provide on-demand heating and cooling.

SUNDRUM SOLUTIONS

SunDrum Collectors increase the energy capture of new or existing photovoltaic (PV) systems.

Power (Watts) Per Panel

Conventional PV

Conventional systems generate only photovoltaic (PV) energy, capturing less than 25% of available solar energy.

SunDrum Solar

SunDrum Solar more than triples the total amount of solar energy captured, simultaneously increasing PV performance and capturing an even larger share of available solar energy as heat.
