MYPV DC-ELWA

Autonomous hot-water with photovoltaics: the patented ELWA
Hot-water with photovoltaics is a new technology. It was possible because of the enourmous decline in prices of PV-modules. We have recognized this trend early and patented the idea. In contrast to conventional solar-heat-systems there is no closed loop with liquid, but cables that carry the energy from the modules to the boiler.There is the ELWA, our invention. It is mounted in the boiler and heats up the water. There is no need for pipings and pumps. Problems with frost and steaming collectors are now things of the past. It is much more simple and cost efficient.

Advantages

• 100 % self-consumption of the solar power
• No permission for the grid connection required
• Easy to install, no maintenance costs
• Easier and cheaper than solar-heat systems
• 2 ELWAs enable stratification charge
• Also works during grid-blackouts
• Hot-Water securing (Boost-Backup) included
