DuPont has been studying panel degradation in the field for over a decade, building on its extensive materials experience. Some degradation is visual with no impact on power, but can have serious safety implications, whilst other types of degradation are invisible, but will sometimes trigger much larger power losses than initially foreseen. These cases illustrate both types of degradation where action needed to be taken, either to secure sites or to restore power production.

Introduced in 2019, DuPont Clear Tedlar® backsheets, designed for bifacial panels are breathable, lightweight, help lower the cell operating temperature by 1 to 2 degrees Celsius, depending on installation conditions and are easy to clean. Clear Tedlar® backsheets enable higher power output, with both lower levelized cost of electricity and total ownership costs.

JinkoSolar launched the Tiger series of high-efficiency tiling ribbon module at the All Energy Exhibition in Australia on October 23, 2019. The Tiger module adopts the advanced technology of multi-busbar + Tiling Ribbon + half cut, with the high-efficiency Jinko cell, the maximum power output of Tiger could reach to 475W, and the efficiency could reach to 21.16%. Tiger series include mono-facial and bi-facial types. The bi-facial Tiger modules currently promote transparent back sheets with DuPont Tedlar. While ensuring a 5% -30% backside energy gain, the light-weight feature of transparent back sheet also effectively reduces the LCOE.

JinkoSolar launched the Swan bifacial with transparent backsheet, which won the 2019 Intersolar Award as the only module product with its innovative technology, excellent performance and forward-looking product design. Up to now, the total order of Swan bifacial modules is nearly 2GW. In addition, Jinkosolar has carried out field test projects all over the world, and has cooperated with PVEL, Chinese Academy of Sciences, NEXTtracker and other third parties to study the power generation performance of bifacial modules and factors affecting the bifacial gains, to provide reference and suggestions for customers to design bifacial power stations.

In this paper, we focus on two leading areas for yield improvement:

Differential elevations from one tracker row to the next that cause either inter-row shading and/or a backtracking algorithm that is set too loosely, reducing energy yield for most of the field.

Diffuse light conditions that reduce energy yield when arrays follow standard astronomical tracking positions.

TrueCapture™ is an intelligent, self-adjusting tracker control system that increases typical PV power plant energy by up to 6%. TrueCapture boosts solar power plant production by continuously optimizing the tracking algorithm of each individual row in response to site features and changing weather conditions. In this video, we travel to the state of Mississippi in the United States where parcel shapes are highly irregular due to rolling terrain. Due to undulating project sites and construction variances, shadows appear on the modules, blocking sunlight and lowering planned (and modeled) production.TrueCapture solves both challenges (terrain undulation and overcast skies) with a unique, integrated approach. Over the course of the day, TrueCapture continuously dispatches optimal tracking algorithms to each tracker row, correcting for shading anomalies caused by uneven ground and changing weather conditions.

No. of NX Horizon rows – 4,075
Modules – 338,662
Inverters – 36
Performance Boost – up to 3.5 %

NEXTracker’s TrueCaptureTM smart tracker control technology is a new innovation to increase production yield on solar power plants and allows owners and developers with closed-loop data and communications connectivity to maximize performance and enhance their financial returns over the lifetime of the plant. TrueCapture dynamically adjusts the angular position of each independent tracker row in response to site topography, weather conditions, and geospatial location of the arrays.

Now operating on 1,000s of MW worldwide, TrueCapture combines advanced sensor, weather forecasting and machine-learning technologies to maximize energy yield. With its smart data capture and model-based predictive control software, TrueCapture helps customers maximize the benefits of their NEXTracker systems, generating more revenue with higher energy yield, better availability, and lower operating costs.

Have a glance at the Huawei FusionSolar successful cases all over the world!

On April 16, when India was still on lockdown due to the COVID-19 pandemic, a 50 MW PV plant in Rajasthan State was successfully connected to the power grid. This project was constructed by Adani Green Energy, a new energy subsidiary of the Indian energy conglomerate Adani Group. To date, Adani Green Energy has put 2.6 GW of renewable energy projects into operation, among which over 96% use Huawei Smart PV Solution

Over the last few years, AI has become a high-frequency word, and it is enabling us to deal with new challenges, pursue better lives, explore science, and coexist with nature in harmony. For example, during the prevention and control of the COVID-19 pandemic, AI is playing a vital role in facilitating virus analysis, drug research and development, intelligent temperature measurement, as well as auxiliary diagnosis.

SOLAR AS A KEY PART OF THE NEW EUROPEAN GREEN DEAL

On December 2019, the European Commission unveiled its proposal for a European Green Deal, with the aim to make European the world’s first climate-neutral continent by 2050. As the lowest cost and most easily deployed renewable technology, solar has a key role to deliver on Europe’s ambitions. This session will look at the key policy and regulatory challenges to make Solar the core of Europe’s future energy system, and deliver on the long term jobs and growth promised by the European Green Deal. It will also reflect on the impact of COVID-19 and draw-up proposals for a solar-proof EU recovery plan.
