So if solar won’t be growing in the United States, where should developers look for new markets? One place is in disaster relief. Yung Wong, engineering manager with WorldWater and Solar Technologies explained that when disaster hits, the first thing that the Red Cross and the military do is fly in water bottles. He said that the cost to transport water comes out to about $1.85 per gallon whereas his company can provide drinking water for just a few cents per gallon though a mobile self-sustaining system that purifies water from any source. The system includes 3 kW of solar PV capacity and a 31-kWh deep cycle battery bank and transports as a 7-foot cube.
