A report published by the Rocky Mountain Institute makes recommendations for rooftop PV in regions affected by high winds. The study draws on the knowledge of structural engineers asked to analyze 25 solar systems across five Caribbean islands after they were hit by major hurricanes in 2017 and last year.

Black Hills Energy is seeking 200 MW of solar power or wind plus energy storage capacity as part of a request for proposal, driven by summer 2019 bids for solar+storage of $0.024/kWh and $0.036/kWh and looming cuts to the 30% investment tax credit.

Researchers in the U.S. claim to have developed a manufacturing process based on the use of a latex balloon that could lead to the production of more efficient curved electronic devices, including hemispherical solar cells.

An International Energy Agency report estimates the share of nuclear power in advanced economies could fall by two-thirds by 2040, as aging plants retire. The report claims without support for nuclear, the transition to a low carbon energy system would be far more complex and threaten global emissions targets.

While U.S. senators Ed Markey and Alexandria Ocasio-Cortez introduce a resolution for a clean energy package, legislation has been tabled in six states aiming to implement 80-100% clean energy by 2050 or earlier.

Xcel Energy’s 120-day report to Colorado regulators includes an additional 1.1 GW of wind at 1.1-1.8¢/kWh. Solar power bids have come in at 2.2-2.7¢/kWh, and solar+storage at 3.0-3.2¢/kWh.

The U.S. National Renewable Energy Laboratory (NREL) has launched a new software package, developed alongside SunPower and kWh Analytics, which it says will improve the accuracy and reliability of PV plant performance data, and improve the industry’s understanding of degradation.

The Swiss equipment provider has announced a plan to close production for its diamond wire platform in Colorado. The company blames global pressure on prices and margins. Meanwhile, its preliminary financial results for 2016 show a 40% increase in sales.
