Hot water with photovoltaics heating element
Hot water through PV solar power
How it works:
1. Electricity surplus:
The photovoltaic system often generates more electricity than is directly consumed in the household, especially when the sun is shining.
2. Heating element:
Excess electricity is fed to a heating element in the hot water tank.
3. Heat conversion:
The heating element converts the electricity into heat and heats the water in the storage tank.
100-liter hot water tank ETWS
The Hot water tank The 100-liter ETWS combines state-of-the-art technology with high reliability for centralized hot water preparation. A highly efficient heat exchanger with a surface area of 1.2 m² harnesses the thermal energy from your solar system or boiler to heat up to 180 liters of domestic water conveniently and economically.
A high-quality enamel coating on the inside of the tank, complemented by a generous magnesium anode, ensures long-lasting corrosion protection. Thanks to the integrated polyurethane insulation, heat losses are kept to a minimum (only 28 W power loss) and the temperature is maintained up to a maximum of 95 °C.
High-performance bifacial PV solar module Trina Vertex S+
The Trina Vertex S+ module delivers a peak output of up to 435 Wp and achieves one of the best efficiency levels on the market at 21.8%. The bifacial double-glass design effectively utilizes both the front and back light, increasing energy yield by up to 85%.
The robust construction, with a compressive strength of 5,400 Pa at the front and 4,000 Pa at the rear, ensures maximum resistance to hail, snow, and wind pressure. Measuring 1,762 mm long, 1,134 mm wide, and weighing 21.8 kg, the module is versatile for use on residential and commercial roofs.
1.5 kW heating element for reliable support
The 1.5 kW Electric heating element Made of high-quality stainless steel, it allows precise temperature control between 5 °C and 75 °C thanks to the integrated thermostat. A switch-on hysteresis of 7–10 °C ensures stable temperature values and minimizes switching cycles.
With its frost protection function and a safety temperature limiter at 93°C, the heating element can be used safely even on cold days. The compact installation length of 300 mm, IPX4 protection, and an operating pressure of up to 10 bar make it the ideal addition for Hot water storage tanks and PV solar systems.
