BIPV Energy Yield API helps developers and engineers model solar energy performance for building-integrated photovoltaics. The API estimates: • annual energy yield • performance ratio • solar system efficiency • financial metrics such as LCOE, NPV, and IRR • CO₂ savings and environmental impact Models are based on peer-reviewed research and validated against IEC, EN, and IEA PVPS methodologies. Designed for developers building solar software, energy platforms, and engineering tools.
