Photovoltaic (PV) batteries exhibit distinct mechanical properties that render them well-suited for integration into solar energy systems. These properties include the ability to withstand mechanical stresses, such as bending or pressure, during the handling, installation, and operational phases of use. High durability is essential to ensure consistent performance across diverse environmental conditions over their extended service life. This study presents empirical data derived from laboratory testing of solar cells, with a focus on comparing the battery charge percentage displayed by a 12/24V charge controller against theoretically estimated values. The calculations are based on the voltage difference (ΔV) between the open-circuit voltage (Voc) and the minimum standard battery voltage. The analyzed results were normalized into percentages, resulting in the development of an equation that demonstrates strong alignment with experimental observations. A comparative assessment of various battery technologies is presented, along with an investigation into the mechanical properties of solar cells. The findings indicate that advanced materials, including perovskite and monocrystalline silicon, when combined with optimized manufacturing techniques such as roll-to-roll processing and laser scribing, significantly improve charging efficiency.
