How Efficient Will Solar PV Be In The Future? 10-Year Predictions For The Industry

If you were to walk into a solar store and purchase some of their best-selling PV panels, it is likely that their solar irradiance-to-electricity conversion efficiency would be around 17%. This is the typical efficiency (Fraunhofer ISE Photovoltaics Report, 2017) of the top-selling PV product, a multi-crystalline silicon panel. This means that for a typical panel, 17% of all incident solar energy is converted directly to usable electricity. This is quite impressive for a device that has no moving parts and can generate power at the location where the electricity is required (no transmission losses). It is no wonder that PV is already one of the cheapest power technologies available.

Current Solar Module Efficiency Nowhere Near Its Potential, Especially Thin-Film Solar & CPV (Chart)

National Renewable Energy Laboratory (NREL) Director Dan Arvizu recently gave a keynote speech during the 2013 International Renewable Energy Conference (part of Abu Dhabi Sustainability Week), which I was lucky enough to attend*. His speech covered a large variety of cleantech topics, and most of the points he made have been covered extensively here on … [continued]

UK Company Likes Its Energy Naked

  A cleantech start-up out of the UK, Naked Energy, has created a technology that’s a little over my head, but that looks quite cool. Basically, one of the key challenges of solar photovoltaics (PV) is that their efficiency drops if they get too hot. Naked Energy, in response, has … [continued]
