1.In the article “Snapshot of Photovoltaics − February 2024,” Jäger-Waldau (2024) reports that global installed solar photovoltaic capacity exceeded 1.6 TWp by the end of 2023, with more than 420 GWp of new capacity installed in 2023 alone. This supports the claim that worldwide PV usage grew rapidly and became a mainstream electricity source by 2023.https://www.epj-pv.org/articles/epjpv/full_html/2024/01/pv20240013/pv20240013.html

2.In the article “Photovoltaic Solar Cells: A Review,” Al-Ezzi and Ansari (2022) explain that solar PV technology converts sunlight into direct current electricity in solar or PV cells. They also state that solar panels are made of multiple solar cells connected in series and parallel, and that PV energy conversion commonly uses crystalline silicon or thin-film semiconductor materials. This supports the claim that PV modules are composed of many solar cells and generate electricity through the photovoltaic effect using crystalline silicon or thin-film cell technologies.https://www.mdpi.com/2571-5577/5/4/67

3.In the article “Design of a Solar Cell Electrode for a Shingled Photovoltaic Module Application,” Oh et al. (2020) explain that photovoltaic module fabrication involves dividing and interconnecting solar cells into strings arranged in series and parallel to produce a module. They also state that, in a general PV module, metal ribbons are soldered onto the busbars of solar cells to connect them to other cells, and that the busbar acts as a shading area, causing loss of the light-receiving active area. This supports the claim that solar cells must be electrically connected to form a module and that front electrodes can slightly block the optical surface of the cell.https://www.sciencedirect.com/science/article/abs/pii/S0169433220301768

4.In the article “Model of Series-Parallel Photovoltaic Arrays Using Double-Diode Model and Parallel Computing,” Bastidas-Rodríguez et al. (2022) explain that PV array power production depends on the voltage and current of the interconnected modules. They also state that the series-parallel structure is the most widely used configuration for both small and large PV installations, with strings made of modules connected in series. This supports the claim that solar installations commonly use multiple panels connected together to increase usable system output.https://www.mdpi.com/2079-3197/10/6/100

5.In the article “Solar Irradiation on the Rear Surface of Bifacial Solar Modules: A Modeling Approach,” Durusoy, Ozden, and Akinoglu (2020) explain that bifacial PV modules increase energy yield by capturing rear-side illumination as well as front-side light. They also state that rear-side irradiation depends on installation conditions such as module elevation and ground albedo, supporting the claim that bifacial output gains depend on surrounding reflectivity and raised mounting structures.https://www.nature.com/articles/s41598-020-70235-3Fsgxn (talk) 10:55, 21 May 2026 (CDT)
