The 2026 American Solar Challenge (ASC) officially concluded on August 1st local time in the United States. The Delft Solar Team from the Netherlands ran 4080.5 kilometers in an 8-day race and won the runner up. According to the competition rules, the battery array area of a single seat solar powered racing car must not exceed 6 square meters. The team needs to capture as much sunlight as possible within the limited area and convert it into energy to drive the car forward.

After the game, we talked to electrical engineer Jorop from Delft Solar Team and asked him to share the stories of the 8-day race and the real performance of Longi BC batteries.

A ultimate test under the sun



2026年美国太阳能挑战赛（ASC）于美国当地时间8月1日正式收官。荷兰Delft Solar Team在8天赛程中跑出4080.5公里，获得亚军。根据赛事规则，单座太阳能赛车的电池阵列面积不得超过6平方米，车队需要在有限面积内尽可能多地捕获阳光，转化为驱动赛车前行的能量。

赛后，我们和Delft Solar Team的电气工程师约罗普聊了聊，请他谈谈这8天赛程中的故事，以及隆基BC电池的真实表现。

一场阳光下的极限考验



As the electrical engineer of the team, Jorop is responsible for the design and manufacturing of the solar photovoltaic panels used in the race car. This year marks the first time that Delft Solar Team has used Longi BC cells in an ASC race. Compared to last year, this technology has made significant improvements, and the output power of Longi BC solar panels is higher than in previous years. ”He said.

During the competition, the team's daily work starts at 6am: dismantling the campsite and preparing for the day's race; The driving time is from 9am to 6pm; After 6pm, the entire team reunited to celebrate the day's achievements together. Jorop said that the moment that made him most proud was when the car overtook other teams on the road or ring track. "At that moment, the entire team felt tremendous joy

The ASC track extends all the way from Minnesota to Texas, with drastic weather changes. Jorop recalled that the air near Minnesota was very humid, but after entering Texas, it became unusually hot, with temperatures reaching 43 degrees Celsius at noon. Sleeping in a tent at night, you often feel sweat flowing down your back. Drivers need to drive their cars in an environment around 40 degrees Celsius, relying on ice packs and plenty of hydration to complete the race.



作为车队的电气工程师，约罗普负责赛车所用太阳能光伏板的设计与制造，今年是Delft Solar Team第一次在ASC赛事中使用隆基BC电池。“相比去年，这项技术已经有了非常大的提升，隆基BC电池板输出功率比往年更高。”他说。

比赛期间，车队每天的工作从早上6点开始：拆除营地、为当天比赛做准备；上午9点到下午6点是驾驶时间；下午6点后，整个团队重新集合，一起庆祝当天的成果。约罗普说，最让他自豪的时刻，是赛车在公路赛段或环道上超越其他车队的时候，“那一刻，整个团队都感受到了巨大的喜悦。”

ASC赛道从明尼苏达州一路延伸到得克萨斯州，天气变化剧烈。约罗普回忆，在明尼苏达州附近空气非常潮湿，进入得克萨斯州后则变得异常炎热，中午气温一度达到43摄氏度。晚上睡在帐篷里，常常能感觉到汗水顺着后背流下。车手们需要在40摄氏度左右的环境中驾驶赛车，依靠冰袋和大量补水坚持完成比赛。



Despite the extremely harsh weather conditions, our cars and drivers still performed exceptionally well, "said Jorop.

6 square meters: Where does energy come from?

In such a harsh environment, the power generation performance of Longi BC batteries has become the key to the continuous progress of racing cars. Jorop said, 'Even in variable weather, our race car can still maintain a very fast speed because the Longi BC solar panels can provide us with sufficient energy.'. ”He said that it is precisely because of the excellent battery performance that racing cars can reach the maximum speed limit most of the time.



“尽管天气条件非常恶劣，我们的赛车和车手依然表现得非常出色。”约罗普说。

6平方米：能量从何而来？

在这样严苛的环境下，隆基BC电池的发电性能成为赛车持续前行的关键。约罗普表示：“即使天气多变，我们的赛车依然可以保持非常快的车速，因为隆基BC太阳能电池板能够为我们提供充足的能量。”他说，正因为电池性能出色，赛车大多数时候都能达到规定的最高限速。



For Jorop and the team, the role of Longi BC batteries is direct and crucial: "Without solar panels, there is no source of energy; without an energy source, we cannot move forward

In this year's ASC, the Delft Solar Team will focus on breaking through the limits of energy density in their technology. Under the fixed limit of 6 square meters, every slight increase in conversion efficiency means that the racing car can obtain more available energy. The efficient BC cell solution provided by LONGi for Delft Solar Team, with leading conversion efficiency, helps the team to push the energy capture capability of every inch of the illuminated area to a higher level within a regular boundary of 6 square meters.

This is not theoretical data from the laboratory, but from practical validation on the racetrack. Jorop said, 'Thank you very much to Longi for providing us with such excellent BC batteries.'. ”



对约罗普和车队来说，隆基BC电池的作用直接而关键：“没有太阳能电池板，就没有能量来源；没有能量来源，我们就无法前进。”

本届ASC中，Delft Solar Team将技术重点放在能量密度的极限突破上。在6平方米的固定限制下，每提升一点转换效率，都意味着赛车能获得更多可用能量。隆基为Delft Solar Team提供的高效BC电池方案，以领先的转换效率，帮助车队在6平方米的规则边界内，把每一寸受光面积的能量捕获能力推向更高水平。

这不是实验室里的理论数据，而是来自赛道上的实战验证。约罗普说：“非常感谢隆基为我们提供如此出色的BC电池。”



For Longi, the ASC arena is both a testing ground for technology and a starting point for continuous breakthroughs. The cooperation between LONGi and Delft Solar Team is based on joint research and development co creation. The team works with LONGi's R&D engineers to continuously adjust the plan according to the competition requirements, ultimately creating reliable and efficient BC products and energy supply solutions.

8 days, 4080.5 kilometers, zero emissions. Sunshine is the only source of energy for racing cars, and the Longi BC battery truly converts this 6 square meters of sunlight into the energy that drives the team forward.



对隆基而言，ASC赛场既是技术的试炼场，也是持续突破的起点。隆基与Delft Solar Team的合作建立在联合研发共创之上，车队与隆基的研发工程师一起，针对比赛需求持续调整方案，最终打造出可靠、高效的BC产品和供能方案。

8天，4080.5公里，0排放。阳光是赛车唯一的能量来源，而隆基BC电池让这6平方米的阳光，真正转化成了驱动车队前行的能量。
