Mexican government halts grid connection of new solar and wind projects

The move has been brought in by the National Energy Control Center which claims it is necessary to safeguard energy security during the Covid-19 public health crisis. Critics say the authorities are using the pandemic as an excuse to extend a pattern of action against the renewables industry.

Storing solar and wind energy with compressed air

Researchers have studied the potential of using compressed air to store renewable energy in offshore saline aquifers. The technology could hold 77-96 TWh for up to two months in British waters, although the costs have proven hard to pin down.

A perovskite electrode to improve hydrogen production

The material was used by scientists in the U.S. in electrochemical cells which use electricity to separate steam into hydrogen and oxygen. The researchers say the oxide of perovskite used in the electrode improves cell performance and reduces operating temperatures.

Trina secures 105 MW order for its 500 W modules

The Chinese manufacturer will provide Indian developer SunSource Energy with its Vertex panels. Shipments will be made in the fourth quarter.

Another 11 solar mini-grids for Mozambique

The public body responsible for expanding access to electricity is seeking consultants to prepare a tender for rural PV mini-grids.

Pakistani regulator expects solar capacity to hit 27 GW by 2047

Solar and wind are expected to account for a growing share of the electricity mix in the years ahead, rising from around 3% at present to 23% by 2030. Over the following two decades after that, however, this share will likely remain unchanged, as the national regulator expects the country to deploy more coal-fired generation capacity.

LCOE from large scale PV fell 4% to $50 per megawatt-hour in six months

Analysts at Bloomberg New Energy Finance say the lowest-cost projects financed in Australia, China, Chile and the UAE in the last six months hit a levelized cost of energy of just $23-29/MWh and the best solar and wind projects will produce electricity for less than $20/MWh by 2030.

Mini perovskite module with 18.13% efficiency

Scientists from Singapore have developed semi-transparent perovskite solar cells that can be easily integrated into a range of urban contexts, including building facades, gates and windows. The 21cm2 mini panels are made of perovskite solar cells based on methylammonium lead iodine (MAPbI3), with an efficiency of 20.28% for 0.16 cm2.

Cost-effectiveness of PV module cooling techniques

Researchers in Malaysia have proposed a new method to determine the best way to design PV cooling systems. They will rank cooling technologies by manufacturing costs and expected panel output.
