What is a holistic approach to photovoltaic module frame improvement?

We present a holistic approach for the photovoltaic (PV) module frame improvement that considers mechanical, electrical, economic, and ecological aspects for different frame designs. In a comprehensive study, the approach is applied to exemplary PV module frame designs.

Does frame design affect the electrical performance of PV module?

Regarding the electrical side of the analyses, results show that the frame design has a small impact on the electrical performance of PV module. Increasing the front frame width to 20 mm results in decrement of 0.92 W and 0.05% regarding power and efficiency respectively compared with the PV module with the reference frame design.

What are photovoltaic panels?

The photovoltaic (PV) panels currently existed on market are laminated plate structures, which are composed of two stiff glass skins and a soft interlayer. Some panels are installed on the buildings and integrated as the components of the structures, such as wall and roof.

How can a hybrid PV-mechanical energy harvesting system work?

Rahman et al. proposed a model to harvest solar radiation and mechanical vibration by using PV, piezoelectric and electromagnetic mechanisms, and based on which they designed a hybrid PV-mechanical energy harvesting system. Simulations showed that the hybrid system can generate an output power of 499.4 mW.

Does PV module deflection due to mechanical load affect CTM factors?

No deflection of the PV module due to mechanical load is considered by the calculation of the CTM factors. Frames are typically manufactured by extrusion molding of aluminum ingots. Those ingots include the raw material price and the costs of manufacturing the billet used for further extrusion.

What is the power output response of a polysilicon solar module?

Real-time power output response of a 30 mm by 24 mm polysilicon solar module during the cleaning process. The module was connected to a resistive load for power monitoring. The insert shows the top view of the cleaning process with three continuous cleaning cycles. The droplet is 13.5 µL in volume at a vibration frequency of 50 Hz.
