Renewable Energy Sector
STAC Srl offers consultancy and solutions for the exploitation of solar energy in order to operate its electric pumps. The more effective solutions are those without batteries, which have following advantages:
The basic idea is to accumulate water in tanks instead of electricity in batteries, so when the sun shines, the pump starts automatically and fills the tank (until it turns off thanks to a float switch). Thanks to the inverter that regulates and protects the electric pump, it can work with significant flow rates and pressures and can also be used directly for irrigation or water supply.
The system is proposed for submerged pumps, but almost all the pumps available in the catalog can be connected to photovoltaic panels through an inverter that we can supply.
