Estimating the learning curve of solar PV balance–of–system for over 20 countries: Implications and policy recommendations

Solar photovoltaic systems installed on homes and commercial building rooftops are deemed central for a low-carbon future. As capital costs of photovoltaics continue to fall, its role towards making buildings more sustainable and environmentally-friendly will continue to grow. Capital costs of a photovoltaic system comprise the module and balance-of-system costs. The latter refers to everything-else needed to make the photovoltaic system...
