With the passing of twin initiatives, New York has set an ambitious plan to raise its energy storage capacity to 1.5 GW by 2025 and 3 GW by 2030.

Alta Devices’ gallium arsenide solar research cells have been certified with a 29.1% efficiency, setting a new single junction solar cell efficiency record. The most significant change, however, isn’t actually the efficiency; it is that the weight fell 30%, and from the words of Alta Devices, its process has lowered material costs to “essentially nothing”.

As expected, Germany’s second chamber of parliament has passed a new package of laws. They will enter into force on January 1, 2019. Among the the changes are the extraordinary FIT cuts for rooftop systems between 40 and 750 kW in size for February, March and April, and new tenders for wind and solar totaling 4 GW.

U.K. renewable investment firm Octopus has signed another private PPA in Italy, this time with EGO Group for 63 MW of unsubsidized solar PV projects. Meanwhile, Canadian Solar Inc. has signed a 10-year PPA with TrailStone GmbH for the energy generated from a 17 MW project in Sicily.

As the dust settles on an imperfect, but still welcome, international agreement thrashed out at COP 24, the chairman of the European Energy Research Alliance has criticized the solar industry for its lack of representation in Katowice.

The Saudi developer is reportedly suffering fines of $700/MW/day for late delivery of a project at the Benban solar complex in Egypt as 180 MW of plants near completion.

The concept of revamping and repowering is one of the newest terms in the solar industry. As the installed base of PV systems ages, the concept of upgrading and improving operating plants becomes increasingly relevant to both manufacturers and PV plant asset managers. However, the real market size for new PV components in existing plants will depend on the characteristics of each plant, the overall regulatory framework and the economic benefits that will accrue to asset managers.

Photovoltaic manufacturers in Asia are importing deposition reactors from the EU to test the latest word in silicon solar cell passivation. Two thin buffer layers sandwiched between silicon wafers and metal contacts are increasing the efficiency of conventional solar cells and setting new records. Equipment suppliers expect the technology to spread through the industry and boost their bottom line.

Con Edison states that it has become the number two solar power generator in North America with the finalization of its Sempra purchase which included 980 MWac of operating solar.
