SunPower and Enphase team up with microinverter acquisition

Through the deal SunPower gets $25 million and stock; however the bigger deal may be Enphase’s right to be the company’s exclusive residential inverter supplier.

United States: Large-scale solar stays strong in Q1 2018

Thanks in no small part to modules stockpiled before the Section 201 tariffs hit, both the utility-scale and “non-residential” market segments grew year-over-year in Q1. And while the duties are expected to play a greater role in 2019, there are other factors supporting ongoing market growth.

University of California gives electrons a one-way ticket

A new study from University of California, Riverside, uses electric dipoles to accelerate electron in one direction, whilst completely stopping it in the other. The discovery, according to researchers, could lead to improvements in solar cell and other energy conversion technologies.

First Solar breaks ground on 1.2 GW factory in the US

The plant is the second-largest planned in the Western Hemisphere, and will triple the thin film module maker’s manufacturing capacity in the United States.

Lowest public solar power contract in the United States: 2.49¢/kWh

Arizona’s largest power user has approved a 20-year power contract with a 30 MW solar project at 2.49¢/kWh, the lowest price for a public solar power contract to date. The deal also involves shutting down a coal plant.

SolarPower Europe revises down global outlook for 2018… but only a bit

Despite recent developments in China, the European solar association believes global newly installed PV capacity this year will reach 102 GW, only 5 GW lower than its previous guidance.

More haste, less speed – or momentum – for PV efficiency related research

Physicists at MIT and in Haifa have come up with a theory for slowing down light that could dramatically improve solar PV cell efficiency – the question now is whether it will work in practice, and on silicon.
