Italian solar panel manufacturer Sunerg Solar announced that they have developed a 1,500 W water heater solution that can be operated simultaneously with a solar panel and mains electricity. Based on the MPPT (Maximum Power Point Tracker) controller, the system can work with a photovoltaic module with a power output of up to 450 W.

Solar panel can produce 2,800 Wh per day

The company presents the Frog Photovoltaic Geyser with its own solar module, MPPT controller and 80 L water boiler with two resistances, one of which is activated by a photovoltaic panel. All the electricity produced by the module is injected into the kettle via the FROG V10 controller.

The cauldron measures 45 cm x 75 cm and weighs 22 kg. It will be sold by the company together with its own solar modules, preferably with the X Max XL panel with a power output of 320 W to 340 W and efficiencies ranging from 19.18% to 20.38%. The panel weighs 18.3 kg and its operating temperature is between -40 C and 85 C.

According to the manufacturer, the solar panel can produce about 2,800 Wh per day and the heater can raise the water temperature from 20 C to 50 C. The daily thermal energy given to the resistance is approximately 2.410 kCal. The company offered the entire system for sale with a total price tag of 1,200 euros.
