Hello,
has anyone had experience with 2Power panels, such as those from Nelskamp, which generate both electricity and heat in a single collector?
We are interested in installing solar thermal systems on the roof combined with solar power. These modules are said to produce more electricity through their own cooling (using the solar thermal function), help prevent snow and ice accumulation in winter, and require less roof space. The electricity generated would mainly be for self-consumption; for feeding electricity into the grid, you would definitely need to install dedicated photovoltaic modules.

Hello Jacob,
I have no experience with these types of modules, but I looked into the topic about two years ago. It’s possible that things have changed since then, but the main reason I eventually decided against these modules was their comparatively high price.
Let me see if I can recall the information correctly (from memory):
- Cooling is achieved by pipes running underneath the panels, which carry away the heat.
- This heat is then used for heating water, etc.
- Since the output of photovoltaic modules decreases when the module temperature exceeds a certain limit (to my knowledge somewhere above 80 degrees Celsius (176°F)), removing the heat can increase energy yield by about 10%.
That’s the theory. However, whether this system produces enough heat in winter—when the modules typically generate little energy and are naturally cooled—is something I don’t know (or rather, I doubt it).
At the time I gathered information, I was also unsure how mature the technology was. Also, as mentioned, the price per module is significantly higher than for a standard photovoltaic module. It is reportedly also more expensive than a sensible combination of photovoltaic and solar thermal systems.
I recommend that you research this yourself as well — and you can share your findings here for everyone’s benefit.
