Solar Heating & Cooling Case Study - Great Lakes Naval Station Hybrid Solar System

In 2019, SunDrum Solar commissioned a 1,300-collector hybrid solar PV-T Campus at Naval Station Great Lakes in North Chicago Illinois. The systems provide hot water to dormitories and base laundry. The commissioning phase included demonstrating winter performance where the systems were exposed to (-28F) temperatures. The systems have provided over 4000 therms of energy during a cold winter month while providing over 5500 therms of energy during a summer month. The thermal systems include 6 dormitory systems and one additional system supporting the base laundry.

Solar Heating & Cooling Case Study - The Elks Lodge

The Elks Lodge in Palo Alto CA decided to retrofit their 1000+ panel 362kW Canopy PV array with 120 SunDrum® Solar SDM100-300 collectors (78kWth) to heat their 3300 ft2 pool. The system goal was to eliminate natural gas consumption except for 8 weeks in the winter.

Solar Heating & Cooling Case Study - Wailea Inn Hybrid Solar System

In February 2019, SunDrum Solar commissioned a 40-collector hybrid solar PV-T system at Wailea Inn on the island of Maui, HI. This system now serves as the main source of heat for their DHW and their pool, and is configured such that space heating and A/C can be added easily in the future. The warm, sunny climate in the town of Kihei enables this system to run at excellent COP’s year round, and to provide a substantial portion of their heating load directly from the sun.

Solar Heating & Cooling Case Study - Alaska Village Housing Project

Even at the high latitude of Anchorage, AK, more than 60 degrees north of the equator, solar hot water systems are an effective form of energy. On the winter solstice,  Anchorage receives about six and a half hours of  daylight, while six months later on summer solstice, the sun shines for 21 straight hours. When designed correctly, solar hot water systems can be convenient and economical, even in Anchorage.

Solar Heating & Cooling Case Study - Arminta Apartments

Synthesis Construction removed an old flat-plate solar hot water system and installed a new Apricus evacuated-tube solar hot water system. This system involves 16 ETC-30  evacuated-tube collectors, a SolarHot pump station with built-in brazed-plate heat exchanger, and an 800 gallon Niles Steel storage tank.

Solar Heating & Cooling Case Study - Bakersfield Hotel

In California’s hot Central Valley, a hotel installed a hybrid photovoltaic and solar-thermal system, which involves 42 hybrid PV/Thermal collectors, and 18 additional PV-only panels. Each hybrid collector consists of a PV panel on the front and a solar-thermal collector affixed to the back. The PV panels get energy from direct  sunlight. The thermal collectors get heat from the PV panels and from the ambient air.

Solar Heating & Cooling Case Study - Larkspur Commons

Larkspur Commons has 136 units ranging from 1-3  bedrooms that are rented out to families earning less than 50-60% of the area’s median income. To help keep  utility costs low, the development features a 4,000 square foot   solar hot water system comprised of 16 solar thermal systems (the largest in the state of Montana!) using SunEarth EC-40 Collectors, each with 216 gallons of storage and installed by our friends at Liquid Solar Systems. At present, the system is meeting 60% to 75% of annual hot water load.
