China’s Solar PV Module Exports Reached 37.9 GW ✨ :o    in 2017

March 12, 2018

By Liu Yuanyuan Director of Operations

In 2017, newly installed solar PV capacity worldwide reached 102 GW, soaring 37 percent from a year earlier, while cumulative installed PV capacity surged 33.7 percent to 405 GW, according to statistics from the China Photovoltaic Industry Association. In China itself, newly installed and cumulative installed PV capacity reached 53 GW and 130 GW respectively, accounting for 51.8 percent and 32.2 percent of the total. For the first indicator, the country has ranked first worldwide for five consecutive years while, for the second, it has held the leading position for the last three.

However, when measured in dollars, exports of PV modules only amounted to US$9.45 billion for the first 11 months of 2017, down slightly from a year earlier. Despite the decline in export value, in volume, exports reached 37.9 GW for the full year of 2017, an increase of 16.6 GW in comparison with 21.3 GW for 2016. Exports of polycrystalline modules reached 31.8 GW, accounting for 84 percent of the total, while that of monocrystalline modules added up to 5 GW for 13.2 percent.

During the year, China shipped to India 9.46 GW of modules, of which 8.94 GW or 94 percent were polycrystalline and 0.35 GW or 4 percent were monocrystalline.

Of the modules exported to the Japanese and Australian markets, the polycrystalline proportions reached 79 percent and 83 percent, respectively, while, for monocrystalline, the proportions were 19 percent and 16 percent.

In addition, monocrystalline accounted for 35 percent of the modules exported to the Middle East, slightly higher than the proportion exported to other markets. Polycrystalline modules still dominate the market with a share of 54 percent.

Of note is that in 4Q17, China’s photovoltaic exports to the U.S. surged. According to industrial analysts, in a move to avoid the adverse effects arising from U.S. President Donald Trump’s 30 percent solar import tariffs, U.S. customers rushed in a large amount of photovoltaic products from China in the fourth quarter, resulting in Chinese PV module deliveries to U.S. customers amounting to 12 times that of the first three quarters of the year.

Due to the advantages of low photo-induced attenuation, low power cost and high project yield, polycrystalline modules have a higher performance price ratio than monocrystalline. As a result, it has dominated overseas markets for many years. In 2018, the market is expected to continue the pattern.

Tesla Installing World's Largest Solar Rooftop on Nevada Gigafactory   

By Lorraine Chow

Mar. 15, 2018 12:31PM EST

Tesla has started building a massive rooftop solar array on top of its Gigafactory 1 (GF1) outside Sparks, Nevada.

Once finished, the 70-megawatt system will be the largest in the world by far; the current record-holder is the comparatively shrimpy 11.5-megawatt array in India that can power 8,000 homes.

Building Tesla has posted satellite images of the GF1 construction site, showing solar panels installed on the north side of the factory.

The Gigafactory is part of Tesla CEO Elon Musk's vision to fast-track a cleaner, more sustainable future. He previously announced intentions to power the Nevada building without fossil fuels, relying instead on renewable energy and batteries.

"GF1 is an all-electric factory with no fossil fuels (natural gas or petroleum) directly consumed," Tesla said then.

"We will be using 100 percent sustainable energy through a combination of a 70 megawatt solar rooftop array and solar ground installations. The solar rooftop array is ~7x larger than the largest rooftop solar system installed today."
The Gigafactory 1 is being built in phases so Tesla and its partners can manufacture products while the building continues to expand. It officially kicked off the mass production of lithium-ion battery cells in January 2017.

The building is expected for completion sometime this year, at which point the Gigafactory stands to claim the title of world's largest building by footprint.

Impressively, Tesla touts that its current structure already has a footprint of 1.9 million square feet, which houses 4.9 million square feet of operational space across several floors.

"And we are still less than 30 percent done," the firm boasted.

Once fully built, the Gigafactory will produce 35 GWh/year of lithium-ion battery cells annually, which is "nearly as much as the rest of the entire world's battery production combined."  ;D
