Panasonic HIT Solar Panel Sets New Record For High Temperature Efficiency

When we think of solar panel efficiency, we usually think in terms of how much of the sunlight hitting the panel gets converted into electricity. Output efficiency is normally computed by laboratory testing, where the ambient temperature of the test environment is carefully controlled. That number is important, of course, but the temperature of the …

Air Pollution Can Cut Solar Panel Efficiency By Up To 25%

A new study has disturbing news for India’s solar power industry. It claims that dust and particulate matter (often a by-product of diesel engines) can reduce solar panel efficiency by 17% to 25%. Half this reduction comes from dust and particles deposited on the surface of solar panels which form a physical barrier to the …

Stanford Completes Rooftop Solar On 15 More Buildings

Starting in 2012, Stanford University began an ambitious program to bring solar power to its Silicon Valley campus. The University’s Department of Sustainability and Energy Management reviewed 20 proposals from solar energy companies and analyzed 60 potential sites for solar installations before selecting 15 buildings most suited to rooftop solar. After those 15 systems were …

Warming Up to Solar Energy in Chicago, Cook County

When Chicagoans drive toward Des Moines, Indianapolis and Springfield, they see local wind turbines helping to power our transition to a clean energy future. Here in Cook County, our best renewable energy growth opportunity is installing modern solar energy panels on residential and commercial building rooftops and on underutilized “brownfield” industrial sites. Solar energy development …

This Danish School Has Installed The World’s Largest Solar Facade

A new building in Copenhagen is covered by 12,000 colourful solar tiles, making it one of the largest building-integrated solar power plants in Denmark. The tiles completely cover the building and will provide it with 300 MWh of electricity per year, meeting over half of the new campus of Copenhagen International School’s energy needs. But …

SunPower Shines in France

SunPower is to supply E-Series solar panels totalling 64.4MW for seven photovoltaic plants to be developed by La Compagnie du Vent in France. A large portion of the panels will be manufactured at SunPower’s facilities in France, the company said. La Compagnie du Vent is a subsidiary of Engie. SunPower executive vice president Eduardo Medina …

Not Enough Investment in Renewables: IRENA

Money invested in renewable energy is not enough to reach a climate goal of limiting global warming to 2.0 degrees Celsius, an Abu Dhabi-based green energy organisation said last week. Investment in renewables has increased dramatically in the last decade, but “the rate of growth is not sufficient yet to meet the climate goals”, Adnan …
