Solar tubes that generate electricity and heat

How does a solar tube work?

The inner tube is pumped with water to collect generated heat and meanwhile cool down the device. Such a solar tube simultaneously converts the sunlight into electricity and heat, and is anticipated to highly boost the utilization rate of incident light. 2. Results and discussion

How does a rooftop solar vacuum tube work?

The water is heated in a heat pipe placed inside the vacuum chamber. And as the pressure is less inside the vacuum tube, water boils at low temperatures. Naked Energy's rooftop solar vacuum tubes generate heat as well as electricity. They use the same collector for photovoltaic mechanisms and thermal conversion.

What is a photovoltaic-integrated solar tube?

The photovoltaic-integrated solar tubes are the newest type. It is a hybrid with different additional features: Photovoltaic or solar cells are integrated into this type of solar tube, allowing you to generate electricity while sunlight streams through the tube. Some models come with an in-tube bulb which you can dim as and when you wish.

How does a solar power system work?

The outer surface of the tube is assembled with an organic solar cell to harvest incident light and convert partial of the energy into electricity. The inner tube is pumped with water to collect generated heat and meanwhile cool down the device.
