The performance ratio test is at the core of the handover from EPC to owner. Yet sometimes, even when best practice is applied – and without particularly demanding guaranteed values to be achieved – these tests fail good projects. This can lead to costly delays and wasted effort spent trying to find issues that might not exist. Everoze Partner Dario Brivio reviews the likelihood of this happening and considers ways to increase confidence in the precision of such tests, based on recent independent analysis of real-world projects.

The PV industry has experienced several rounds of price increases since the second half of 2020, from polysilicon to materials such as PV glass and films. Between July 2020 and February 2021, prices quoted for 3.2 mm and 2 mm glass surged by more than 60% per square meter. Prices for EVA and POE encapsulant films skyrocketed by more than 40% and 10%, respectively. Prices for silver paste also rose 7%, and have since remained stubbornly high. PV InfoLink Chief Analyst Corrine Lin examines the impact of silver’s recent price turbulence on PV cell manufacturing.

Annual battery storage installations will exceed 10 GW/28 GWh in 2021, following a particularly strong year in 2020, despite the challenges created by the global pandemic, writes IHS Markit analyst Mike Longson.

Storegga, Shell and Harbour Energy want to set up a 20 MW blue hydrogen production facility in the U.K. Australia’s Origin Energy wants to build a hydrogen facility at the Port of Townsville, in Queensland. South African company Sasol and Toyota South Africa Motors have announced a partnership to “commence exploration of the development of a green hydrogen mobility ecosystem in South Africa,” starting with zero-emission hydrogen fuel cell (FC) heavy-duty, long-haul trucks.

Researchers in the US ascertained that the partial shading provided by solar parks creates a microclimate that favors the abundant growth of more varied flowers and pollinators. They also found that partial shading increases bloom abundance by delaying bloom timing, increasing forage for pollinators during the hot and dry late season.

An group of international scientists has developed a mathematical model to design hybrid renewable energy systems relying on pumped hydro storage for islands. According to their analysis, which was applied to the Ometepe island in Nicaragua, a similar system could provide a cost of energy ranging from €0.047/kWh to €0.095/kWh.

A technology-focused event held by the Africa Solar Industry Association has heard development pipelines across the continent are swiftly changing to accommodate double-sided PV panels, and that’s good news for solar tracker providers too.

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.

New research from Singapore has found that gas pipelines for the onshore transport of green hydrogen and the cables for the transport of electricity to produce it at a distant location have similar costs at a 4000 km transmission distance. For longer distances, gas pipelines were found to be cheaper than cables, although the electric lines are said to benefit from scaling up and higher utilization. For both options, however, a currently too high hydrogen LCOE remains the biggest barrier to overcome.
