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.
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.
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.
A diverse group of energy industry associations including energy efficiency and storage, natural gas, oil, solar and wind issued the following statement condemning the administration’s draft plan to bail out coal and nuclear plants across the country.
Working towards the goal of fully sustainable producti on, Cargill worked to have one of California’s largest solar water heating arrays installed on its flagship beef production facility in the state.
Energy storage systems are being deployed with residential, commercial and utility applications, helping all generation sources connected to the grid become more efficient and cost-competitive. Encompassing a multitude of technologies, including chemical batteries, thermal, and pumped hydro, energy storage stores excess energy and converts it back to electricity when most needed. This inherent flexibility is critical to building a resilient, reliable and sustainable electrical grid.
In August 2017, Wheaton College installed a solar hot water system on the roof of its Haas Athletic Center.
