Solar-powered Water Pumping for Vineyard Irrigation
Problem
The vineyard site is two miles from grid-power. Cost of grid-tied installation estimated at US$ 200,000 plus US$ 1,000 a month service fee and 15 cents per kilowatt-hour. Occasional grid-power outages in area are known to last up to a week, sometimes more.Diesel generators are expensive considering rising fuel prices and risk fuel-spill pollution. Alternatives such as windmill pumps impose other challenges.
Solution
Solar-powered pumping systems are reliable, cost-effective, high-performance, and low-maintenance. LORENTZ solar pumps have the advantage over competing solar pumps, offering pumping systems for a wide range of applications, with brushless design for improved efficiency, modular design for customized installations, easy set-up, and a reputation for longevity. In many cases this solution offers a comparable or lower cost compared to a grid-power installation, as well as offering energy independence with a low environmental impact.
