According to foreign media outlet InsideEVs, Nissan recently unveiled a unique Ariya concept car. The car's biggest highlight is its collaboration with Dutch company Lightyear, which covers approximately 3.8 square meters of solar panels on the hood, roof, and tailgate. Under sufficient sunlight, this system can add up to 14.3 miles (about 23 kilometers) of range per day.   While this solar-powered concept car visually demonstrates the potential of using solar energy to alleviate range anxiety, given Lightyear's bankruptcy and the widespread production difficulties faced by competitors, Nissan has explicitly stated that there are currently no plans for mass production of this car.   Nissan's attempt seems more like a technological trial, aiming to verify whether onboard photovoltaic technology is an effective solution for alleviating range anxiety.   Geographic Location Determines the Upper Limit: Range Increase of Only Three Kilometers Although the concept of "using solar energy for charging" is quite attractive, real-world test data for the Nissan Ariya clearly demonstrates the limitations of this technology, which is heavily reliant on weather conditions.   Test results show that geographical location and weather have a significant impact on the Ariya's charging efficiency. In sunny Dubai, the Ariya can travel an extra 13.2 miles (approximately 21.2 kilometers) per day using solar power; however, in cloudy London, the increase is only 6.3 miles (approximately 10.2 kilometers) per day.   To test the vehicle's performance under these conditions, Nissan conducted a two-hour, 50-mile (approximately 80-kilometer) test on a sunny day. The results showed that the solar system only replenished the battery by 0.5 kWh—equivalent to an increase of less than 2 miles (approximately 3 kilometers) in range after this trip.   For electric vehicles with ranges often exceeding several hundred kilometers, this increase is indeed negligible.   However, Nissan offers another perspective: over a yearly period, for owners who primarily use the vehicle for daily commuting and frequently park outdoors, this system could theoretically reduce charging frequency by 35% to 65%.   This means that although the range increase each time is small, for car owners whose daily driving distance is not long and charging is not very convenient, the cumulative effect over time, this system can still bring real convenience and peace of mind.   Further Setbacks for Competitors: Mass Production Remains a Challenge Looking at the market as a whole, Nissan is not the only automaker attempting to equip electric vehicles with solar panels, but past cases have shown that the commercialization of solar-powered cars is extremely difficult.   Lightyear, a once-promising Dutch startup that planned to manufacture dedicated solar-powered electric vehicles, ultimately went bankrupt due to a broken funding chain and manufacturing difficulties; ...

Kingston, Jamaica – A significant step towards energy resilience and sustainability has been successfully realized in Jamaica, with the recent commissioning of a robust 20kW solar photovoltaic (PV) system coupled with a 40kWh energy storage system. This turnkey project, ordered by a SUNDTA customer, highlights the Jamaican client's trust in SUNDTA's comprehensive, all-in-one solar and storage solutions. The system's seamless operation underscores the superior performance and seamless integration of SUNDTA's proprietary energy storage inverters, lithium batteries, and PV mounting structures.   The heart of this energy independence system lies in SUNDTA's advanced energy storage products.

This is made possible by SUNDTA's in-house photovoltaic mounting system production factory. This vertical integration allows SUNDTA engineers to design and manufacture mounting brackets that perfectly suit the specific installation environment—whether it's a particular roof type, ground co...

The European Commission has released its proposal to revise its Cybersecurity Act (CSA), which includes provisions to exclude “high-risk” companies and components from European supply chains.   The proposal was expected last week (14 January) after a months-long review process, but was delayed, reportedly due to disagreements between officials and member states over the scope of the changes to the CSA.   The proposal outlines measures to identify high-risk “third countries” and companies supplying digital equipment or components to the EU and exclude them from key digital infrastructure.   The Commission said the proposal aims to enable “the EU and Member States to jointly identify and mitigate risks across the EU’s 18 critical sectors”, which includes energy. Though a press statement by the Commission only outlines the “mandatory derisking” of the telecommunications sector.   For renewable energy, particularly solar PV and energy storage, the major “third country” of risk is China, though the Commission’s proposal does not mention the country at all. Chinese companies have supplied the majority of the EU’s solar inverters in recent months, which has raised cybersecurity concerns in the industry and in Brussels. The EU has already identified solar inverters as a “high-risk” supply dependency in its Economic Security Doctrine published late last year.   For example, data from European PV wholesaler Sun.store says that Huawei has been a leading supplier of solar inverters – many of which are digital and connected to cloud servers – despite the fact that the company has been restricted from the EU’s 5G network on security grounds.   The proposal includes provisions to potentially recall and phase out products that are already deployed in EU infrastructure if the supplier is found to be high-risk. Analysed the implications of a phaseout of Chinese technology for the solar sector last week.   The supply chain restrictions focus on “non-technical” risks, which the Commission says refers to the risk that a supplier is “subject to influence by a third country” that could disrupt an essential service or “the exfiltration of data, “including for the purposes of espionage or revenue generation”.   “Cybersecurity threats are not just technical challenges. They are strategic risks to our democracy, economy, and way of life,” said Henna Virkkunen, the Commission executive vice-president for tech sovereignty, security and democracy. “With the new Cybersecurity Package, we will have the means in place to better protect our critical ICT supply chains but also to combat cyber attacks decisively. This is an important step in securing our European technological sovereignty and ensuring a greater safety for all.”   The proposal also introduced clarific...

The photovoltaic industry has ushered in a new track.   On January 8th, photovoltaic stocks generally rose, with perovskite and space photovoltaic concepts being particularly active. By the close, Maiwei Co., Ltd. rose 15.65%, Haiyou New Materials Co., Ltd. rose 14.20%, Autowell Co., Ltd. rose 11.85%, and Junda Co., Ltd. (002865) hit the 10% daily limit, achieving two limit-up days in three trading days. Oriental Sunrise Co., Ltd., Jiejia Weichuang Co., Ltd., Trina Solar Co., Ltd., and Jinko Solar Co., Ltd. all rose by more than 5%.   This surge in popularity didn't come out of nowhere; it started with a vision that sounded like something out of a science fiction movie.   Recently, Elon Musk proposed an ambitious plan: to deploy a 100GW solar satellite network into space annually, using the infinite sunlight in space to power Earth and future AI facilities and computing systems. Previously, he had even stated bluntly: building nuclear fusion reactors is foolish; the sun itself is a free super reactor, and space photovoltaics are the future.   This concept quickly sparked global discussion, with several major domestic photovoltaic companies making public statements, and others already undertaking related work such as cooperation with aerospace and on-orbit verification, attempting to be among the first to establish a foothold in this future sector.   1. Why did space photovoltaics suddenly explode in popularity? First, let's define the concept. Space photovoltaics refers to solar power generation systems that provide continuous power to satellites, space stations, future computing constellations, and deep space missions in space environments such as Low Earth Orbit (LEO) and Medium/High Earth Orbit (MEO/GEO).   This idea wasn't proposed in recent years. As early as the 1960s, American scientist Peter Glasser had systematically envisioned this path. He proposed building large-scale solar power generation devices in space, converting the acquired energy into electromagnetic waves, and then transmitting it wirelessly to a receiving end for use.   What truly makes space photovoltaics worthy of "serious re-discussion" is its inherent physical advantages. Compared to terrestrial photovoltaics, the space environment almost completely avoids all variables affecting the stability of power generation. There are no cloud cover, no day-night cycle, and the intensity of solar radiation remains consistently high. Theoretical calculations show that solar energy intensity in space can be several times that on Earth, multiplying the power generation potential for the same area.   More importantly, there's the stability. Data shows that low-Earth orbit satellites can orbit the Earth approximately every 90 minutes, receiving over 60% sunlight and avoiding interference from nighttime and weather. Furthermore, geostationary orbit satellites only experience brief solar eclipses during the spring and autumn equinoxes, enjoying sta...

Starting at 6:00 AM on December 29th, the main bridge and ramps of the Southwest Second Ring Road Interchange officially opened to traffic. This long-standing traffic bottleneck for Xi'an residents has seen a crucial improvement, with the regional road network structure being restructured, traffic flow effectively diverted, and traffic efficiency significantly improved. A long-standing urban traffic congestion point has been cleared.   However, this opening is not just a traffic improvement.   The appearance of this "sun hat" (referring to solar panels) is not accidental.   Introducing photovoltaics into core urban traffic scenarios has always been considered a highly challenging task. The reason is not the maturity of the technology, but the extremely stringent safety requirements of road conditions. Any factor that might affect the driver's visibility or cause safety hazards is unacceptable. This is why many past "transportation + photovoltaic" projects have remained merely concepts or small-scale pilot projects.   The Xi'an project's choice of a high-traffic, densely populated elevated section of the West Second Ring Road, with its high concentration of nearby residents, itself demonstrates a high degree of confidence in safety. The LONGi Hi-MO X10 anti-glare solar panels installed on top of the sound barrier allow the photovoltaic system to integrate into the city's operation without disrupting traffic.   In terms of scale, this is not merely symbolic. The West Second Ring Road elevated highway is an eight-lane dual carriageway, approximately 685 meters long, with over 20,000 square meters of usable overhead space. The project actually installed approximately 9,600 square meters of photovoltaic panels, with an installed capacity of 2MW, generating approximately 1.95 million kWh of electricity annually and reducing carbon dioxide emissions by approximately 1,900 tons per year. Traffic flow, noise reduction, and power generation are all combined on the same elevated highway.   However, the prerequisite for this scale is that risks are addressed proactively. Glare is the first hazard that needs to be eliminated. The metal grid lines on the front of traditional photovoltaic modules can easily create specular reflections at certain angles, producing dazzling glare. This can not only affect driving safety but also lead to complaints from residents. This problem has long constrained the application of photovoltaics in traffic scenarios.   This project did not choose a reactive approach but instead changed the structure from the source of the modules. The Hi-MO X10 employs BC2.0 back-contact technology, transferring all the metal grid lines from the front of the battery to the back, eliminating the main source of reflection from a physical structure perspective. Actual measurements show a reduction of reflected light of approximately 69% compared to conventional modules. Combined with anti-glare glass and surface tr...
