appealing. Installation and initial cost was also cheaper than solar hot water heaters. The tank was automatic too. Solar water heating was not the same bargain anymore in the United States, especially when oil import limits were allowed to surpass 50 percent. A similar scenario happened later in Japan when it began importing oil in the 60s.Solar Water Pumping Systems | Groundwater EngineeringBecause solar systems only operate during daylight hours the water pumped out is typically stored in a storage tank for use 24 hours per day, to ensure constant availability of water.
