South Africa Solar and Storage Plant Reaches Milestone



A 100 MW solar and storage plant in South Africa has generated its first power to the national grid.

The milestone means that construction of the Kathu Solar Park by Spanish companies SENER and ACCIONA Industrial has taken a major step towards conclusion.

Kathu is equipped with a molten salt storage system that will allow it to keep producing electricity for almost five hours after the sun has gone down. It generates electricity via parabolic trough technology designed by SENER.

Siyabonga Mbanjwa, SENER’s Southern Africa managing director, said that the plant will be operational “in the next couple of months”.

He said once operational, the plant “will provide clean energy to the local community of the John Taole District Municipality, the Northern Cape Province and South Africa as a whole”.

Francisco García Bueno, project director at ACCIONA Industrial, said the plant’s synchronisation “is one of the most important final milestones that will enable us to complete a process that began in 2016”.

We are pleased to inform our friends and partners that GoodWe has been honored this week with the TÜV Rheinland’s 2020 “All Quality Matters” award in recognition for the outstanding quality of its EH Series storage inverter and its MT Series C&I inverter. This is the fifth consecutive year that GoodWe has won this prestigious award, which shows just how consistent the company has been in delivering high-quality products. The award ceremony took place on 30 June in the city of Suzhou and was attended by the company’s founder, Mr. Huang Min.

The evaluation process that preceded the decision for this award was very comprehensive and for this edition, Rheinland started testing one year in advance, only concluding its final report in June 2020. Renowned for its objectiveness and impartiality, the TÜV Rheinland’s “All Quality Matters” award has become an important reference point on a global scale and being a recipient of this influential award is always an honor.

EH Series – Storage Inverter

In 2019 GoodWe was ranked “World’s Number 1 Storage Inverter Supplier” by Wood Mackenzie and there was indeed much speculation about which storage product would receive the glamorous TÜV award this year. It was later confirmed that the EH Series had received the highest score due its versatility, safety and efficiency and overall ease of installation. GoodWe’s EH Series is a high-quality storage inverter with battery-ready function and, as part of this evaluation, it was tested against competitors’ products on the categories of efficiency, output and input capability, power quality and thermal stability. GoodWe is coming first on the below parameters thus becoming this year’s undisputed champion:

1. Efficiency: This inverter can achieve a Max MPPT efficiency of 99.9% and comes with two MPPTs, which makes it a leader among single-phase storage inverters.

2. Max. Input Power: EH Series is the first single-phase storage inverter in the market compatible with bifacial double-glass modules, which allows 12.5A input current per string. It also allows 35% DC oversizing to fully maximize capacity.

3. Max. Output Power: The EH Series proved to be able to improve AC output capability, generating more power thanks to its ability to support 1.1 times rated power output for extended periods.

Apart from its strong performance, EH Series offers customers the possibility to upgrade to a full energy storage solution by simply purchasing an activation code. Moreover, the fact that it takes less than 10 seconds to switch from grid to PV helps users avoid expensive intakes from the grid.
