ETA Enclosures USA provides electrical enclosures designed for renewable energy applications, including solar power inverters, wind turbine control systems, and battery storage solutions. The solar canopy helps to improve water quality, reduce effluent temperature and support a healthier aquatic ecosystem. Ameresco A new solar canopy installed at a wastewater treatment plant in City of Pendleton, Oregon. Small wastewater treatment plants (WWTPs), which treat less than 1 million gallons per day (MGD), make up 79% of wastewater utilities in the United States and play a crucial role in our communities. Because solar adoption at wastewater treatment plants is still relatively new, there is little known about these facilities, including where they are, what drove them to. By installing photovoltaic (PV) cells on the rooftops of our facilities, we're able to harness the incredible power of the sun and convert it into clean, renewable electricity. It is energy saving, environmental protection, suitable for remote or power shortage areas.
