The Institute for Energy Economics and Financial Analysis has estimated the effect on the payback period of PV systems when adding EVs and storage in Germany and Britain. In both cases, system owners are likely to reduce their payback period by significant margins as increased self-consumption can offset the incremental phase out of government incentives.

The UK Labour Party has revealed plans to facilitate the installation of solar panels on 1.75 million homes, with a particular focus on low-income households.

Scientists seeking the next generation of highly efficient PV devices have found inspiration in nature. Researchers from the U.K.’s University of Birmingham and the University of Utrecht, in the Netherlands, examined the light harvesting mechanisms in ocean microalgae that are said to be up to 95% efficient.

A research team has applied a waterproof coating obtained from graphite to a perovskite cell intended to power the production of hydrogen underwater. The cell is said to have worked underwater longer than expected.

Having declared a climate emergency last week, the U.K. government is considering raising VAT rates from 5% to 20% on ‘energy saving materials’ in the home. While the tax authorities are blaming Europe, trade body the REA has pointed out the 5% rate would still apply for coal used for domestic heating.

After two decades of growth, the amount of newly installed renewable energy capacity is no longer rising and, despite a 7% growth in electricity generation from clean energy sources, global energy-related carbon emissions have risen 1.7%.

The back-contact solar cell is said to have a conversion efficiency of around 7%. According to researchers, the cell design includes the removal of expensive transparent conductive oxides.

The asset manager has seen good returns on the 70 MW it has already acquired. Despite the U.K. government cutting subsidies for renewable energy, the fund manager believes the country will be a high growth market for storage.
