Onsite Demonstration Study on Semi-transparent Solar Photovoltaic Vacuum Glazing for Power Generation and Energy Saving
(REF: S-1951) |
| Trial Project |
|
| Solution Feature |
- A semi-transparent solar photovoltaic (PV) panel integrated with vacuum glazing will be developed to replace existing window glazing to generate power from solar energy and reduce cooling load due to its lower U-value.
- High-efficient and reliable solar PV panel (CdTe) will be adopted to make sure that its solar cell efficiency is over 14 percentage.
- Lower U-value of the adopted vacuum glazing could reduce the overall heat loss coefficient to lower than 0.5 W/m2·K so that heat gain from building envelope can be reduced significantly.
- The special solar panel to be developed can offer customizable visible light transmittance of 15-45 percentage to optimize visual comfort and energy performance depending on request.
- Thermal and visual comfort of indoor space can be enhanced due to the use of the special solar panel. At the same time, fire safety level is equivalent to that of traditional laminate glass.
|
| Trial Application and Expected Outcome |
- The proposed solar panel will be manufactured by professional manufacturers and tested first in our Solar Simulator lab to make sure its power generation efficiency and U-value are satisfactory.
- The solar panel will be installed at the EMSD site to replace one window's glazing so that comparison tests can be conducted between this renovated window and another nearby window without renovation.
- A data acquisition system will be developed for testing the heat transfer of the panel and the indoor thermal/visual comfort by adding different sensors on the two window glazing panels with and without renovation. The generated solar power will be used to light the outside garden.
- A 6-month data collection process will be conducted, and validated simulation will be carried out as well so that annual energy and thermal/visual comfort performances can be analysed. An economic feasibility study will also be completed.
- A final report will be submitted. Commercialization effort will be made to promote the developed technology to local industry.
