To understand how green solar energy is, we must assess its life-cycle and each stage''s carbon footprint. This life-cycle assessment (LCA) is a method to evaluate the environmental impacts of products and materials. Over the years, companies have strategically used LCA to research and create more sustainable products.
Solar Performance and Efficiency. The conversion efficiency of a photovoltaic (PV) cell, or solar cell, is the percentage of the solar energy shining on a PV device that is converted into usable electricity. Improving this conversion efficiency is a key goal of research and helps make PV technologies cost-competitive with conventional sources
That means it will produce 0.3kW × 5.4h/day × 0.75 = 1.215 kWh per day. That''s about 444 kWh per year. With California''s electricity costs being around $0.21 per kWh, you''re saving about $93,24/year on electricity costs.
