The Cryosolar solution consists of a 20-foot or 40-foot container equipped with a plug-and-play PV system installed on the roof. It has 180 mm thick insulation and 10 to 35 cubic metres of storage with shelves.

Axter, a French waterproofing specialist, has revealed a new mounting process for the installation of rigid solar modules on several types of buildings, including concrete, metal, and wood surfaces.

Owners and operators of energy storage systems, as well as investors, need transparent ways to evaluate battery performance. They need certainty that the selected batteries for their ESS projects will perform reliably, have predictable life expectancies, and meet projected revenue and contractual obligations over their lifetimes. The economic viability of entire projects depend on this confidence, writes Michael Kleinberg of DNV.

The panel was unveiled in October and is the most powerful product the company has brought to the market to date. The Chinese-Canadian manufacturer expects to reach, for this product, a 10 GW capacity by the end of the year.

The cell showed open-circuit voltage values of up to 732 mV. It was fabricated with a back junction (BJ) design with a full-area p-n-junction at the back surface.

Scientists in Russia introduce a promising new material for battery energy storage, the product of more than three years of research. Incorporating a nickel-salen polymer into the cathode, the group demonstrated a battery that can charge and discharge ten times faster than today’s lithium-ion batteries. And though the battery still lags in terms of overall capacity, the group is confident that its discovery will lead to big improvements for lithium batteries.

Scientists have set a new efficiency record for a single-junction perovskite solar cell at 25.6%. The cell additionally showed operational stability for 450 hours, and intense electroluminescence with external quantum efficiencies of more than 10%.

German start-up Phytonics has developed the film by taking inspiration from nanostructures in plants. In solar cells, the film enables a broader absorption spectrum and a higher angle of light-incidence tolerance.

Suppliers of encapsulant materials – plastic sheets that are heated to laminate together the components in PV module stacks – are rapidly expanding to keep pace with module manufacturing in Asia and other parts of the world. Ethylene-vinyl acetate (EVA) continues to dominate the market, but new developments in module technology are driving a slow shift to more costly polyolefins.

The Recommended Practice guide, on top of describing the most common requirements for building a floating PV array, provides a series of technical guidelines for electrical safety, anchoring and mooring issues, operation and maintenance, and specific plant design that can withstand site-specific environmental conditions.
