VariSun™ Solar Powered Vapor Extraction Systems

​Solar Solutions featuring VariSun™ 3-phase solar controllers from Sustainable Technologies can help you harness the sun for clean, economical remediation and provide a solution for remote remediation where power is too costly for test and deployment. Complete modular mobile solar pump systems come in a variety of sizes.

​VariSun™ solar controllers can turn any three-phase electric pump into a solar pump. Pump water from any location with direct solar power. Systems ship ready to connect to your pump. The system is scalable from 2 HP to 100 HP. When replacing a diesel pump, the complete system usually pays for itself within two years. No more fueling, no more noise, no more pollution. No more air board permits. Best of all, no grid and batteries to hassle with! Just clean, free power from the sun.
