Junior power minister Nasrul Hamid made the declaration yesterday, at an inauguration ceremony for Bangladesh's largest solar rooftop, a $16 million, 16 MW array in Chittagong. The government in March said it would reformulate its renewables policy after it fell well short of a target to generate 10% of its electricity from clean power by last year. Around 3% of Bangladesh's power came from clean sources at that point. “Renewable energy will be the main source of energy in the future,” the minister said on Sunday, emphasizing the benefits offered by commercial solar rooftops. “The share of renewable energy is increasing in [the] fuel mix,” said Hamid, in part thanks to the rising popularity of net-metered solar arrays like the one installed at an export processing zone owned by Korean clothing and textiles company Youngone Corporation. Export processing zones are areas with less onerous customs and tax charges where manufacturing takes place solely for export. The minister said plans to expand the Chittagong array to 40 MW next year would encourage other businesses to follow suit. The politician stressed, however, that the big land requirements of large scale, ground-mounted solar plants would mean wind, tidal and energy-from-waste facilities would also have big roles to play in reaching the government's 2041 target. Youngone Corporation intends to expand its Chittagong project to around 40 MW of generation capacity, with 4.3 MW due to come online before November and the balance expected next year. The intention is for all 34 factories at the Youngone export processing zone to be powered entirely by the eventual 40 MW of solar capacity. With the rooftop array net-metered, any excess power generated will be exported to the grid. Lee Jang-Keun, South Korean ambassador to Bangladesh, said of the rooftop array: “This is how businesses can get along with nature and reduce the threat of climate change.” Bangladesh has around 746 MW of renewable energy generation capacity and the first stage of the Chittagong array has taken the nation to 40.72 MW of net-metered rooftop solar.

The 4.738MW solar plant ,located in Alashankou, Xinjiang where has unique light resources, is under installation. Taking account of local climatic conditions such as extreme low temperature, high snow pressure and heavy sand, the system adopted carbon steel solar structure to achieve better balance between the overall stability and investment. The carbon steel PV mounting system,  which delivered an economical and reliable solutions for photovoltaic projects on a free surface. Strong steel solar structure allows for lager span between footings that can be cost-effective and robust. In order to ensure smooth process while installation, Antaisolar technical engineers came on site to push ahead with the project and to explore any new solutions for further optimization. The project site is located on the border between China and Kazakhstan with average of 10 hours of light per day, and it’s definitely a proper region for developing solar energy.

Last year saw a record for solar, in terms of newly deployed capacity. This year, however, growth may be limited by new regulations for project siting. South Korea’s Ministry of Trade, Industry and Energy (MOTIE) has estimated that around 4.1 GW of new PV systems were grid connected in the country last year. If confirmed by official statistics, this result would compare to 3.8 GW in 2019 and 2.4 GW in 2018 and would make 2020 the most successful year ever recorded by the country. At the end of December, South Korea's cumulative installed PV capacity should have reached around 15.6 GW. Last year “marked the third year after the Korean government's 20%-renewables-by-2030 plan announcement, causing a boom in solar,” Yeji Kim, researcher at Seoul-based Solutions For Our Climate, told pv magazine. “Large scale PV plants–over 1 MW [in scale]–were built in the country for the first time but, unfortunately, we could not find the exact number of installations completed in 2020.” According to her, however, this year's growth may be lower than that of 2020, as several regional administrations are limiting the development of utility scale projects through new regulations for project siting. Citing recent numbers from the Korea Energy Agency (KEA), the analyst said the newly installed PV capacity for the first quarter of this year reached 0.56 GW while, in the same period of 2020, new PV systems had totaled over 1 GW. The Korea Photovoltaic Industry Association (KOPIA) recently said it expects around 3 GW of new PV will be installed in the country this year. “Despite the record growth in South Korea's solar, renewables are still strangled, unable to grow as fast as they should,” Kim added. South Korea currently plans to install 30.8 GW of solar by 2030. This ambitious target is expected to be achieved by building giant solar parks such as a 2.1 GW floating solar project, and a 3 GW ground-mounted PV array that was announced for the Saemangeum area by South Korean president Moon Jae-in in November 2018. More recently, the South Korean government announced a plan to add another 2.1 GW of floating PV by 2030. Furthermore, the MOTIE is planning to allocate around 4 GW of solar capacity this year across two PV tenders, which will likely be launched in April and October. The ministry has also recently announced it wants to help development of unsubsidized solar by allowing domestic electricity consumers to buy power from renewable energy power producers through power purchase agreements (PPAs).

It’s reported that the renewable energy accounts for approximately 20% of its energy mix in Mexico. In 2017, the Mexican Ministry of Energy announced a new energy transition plan on its official website and established the goal of new energy development. It is estimated that new energy will account for 30% by 2021 and 60% by 2050. And it is expected to become the world's seventh largest solar market in 2021. The application of fixed structure solar plants and solar tracker plants are evolving in a rapid way.
