Such deviation affects the testing procedure. Deviation of photovoltaic devices on vehicles is sometimes called “strange behaviors.” We may need a general computation method for general curved surfaces and non-uniform shading (aperture) environments. Accurate modeling will be required to be developed to understand that strange behavior.
Electric vehicles (EVs) with photovoltaic modules that convert sunlight into electricity promise a low-carbon way to drive without needing electric vehicle charging stations, or at least fewer [1, 2]. Placing photovoltaic modules on vehicles, at least as commercial products, and relying on them as the energy source for EVs is challenging.
For example, the current photovoltaic modules have excellent damping properties in 0.1–10 Hz of vibration (typical frequencies in architectural structures), but the vibration of the vehicle roof extends to 2000 Hz.
The curved VIPV module was tested by solar simulators using the protocol in Section 2.3. Simultaneously, the 3D curved profile was measured by a Coordinate measuring machine (CMM). The profile data was also used to determine the position of the reference plane for the solar simulator's calibration.
For curved PV devices, the IAM vector may be represented as a 2D vector (IAM Matrix), and its measurement can be done by a collimated solar simulator . 5. Conclusion We are targeting VIPV to help save the charging frequencies of EVs.
