A canton in Switzerland commissioned a project in which solar panels were attached vertically to a roadside retaining wall.
The canton of Appenzell Ausserhoden in northeastern Switzerland is aiming to generate at least 40% of its electricity from renewables by 2035. So, it exercised a little creativity and covered a roadside retaining wall with 756 glass-glass solar panels.
The panels have an output of 325 kW and an energy yield of around 230,000 kWh annually. This is equivalent to the consumption of about 52 Swiss households. The energy will be fed into the grid of energy supplier St. Gallisch-Appenzellische Kraftwerke, and the canton will get a feed-in tariff in return.
German mounting system provider K2 Systems and Swiss contractor Solarmotion installed the vertical system on the 75-degree retaining wall. The panels were anchored on a mounting rail with HUS screw anchors, and Lichtenstein-based Hilti provided mechanical dowels.
The PV system was anchored on and in the masonry using an adhesive technique. An anchoring depth of a maximum of 90 mm could not be exceeded so that the retaining wall would not be adversely affected.
Due to the close proximity to the asphalt, the solar panels’ components are subject to exceptional corrosion requirements and are anodized for protection. Indirect components are made of aluminum – only the screw anchors are made of stainless steel.
K2 Systems says that “especially in the winter months (when consumption and dependence on foreign electricity imports are at their highest), the vertically aligned modules will achieve a very good electricity yield.”
Electrek’s Take
This isn’t a big project, but it’s a delightfully creative one, which is why it caught my eye. A retaining wall is dead space, and snow will slide off the panels in Swiss winters.
We at Electrek love it when solar is installed in intelligent and inventive ways. Warehouse rooftops? Cover them. Highway medians? Canal covers? Box stores? Put solar on them. It just makes sense.

The US solar industry just delivered another huge quarter, installing 11.7 gigawatts (GW) of new capacity in Q3 2025. That makes it the third-largest quarter on record and pushes total solar additions this year past 30 GW – despite the Trump administration’s efforts to kneecap clean energy.
According to the new “US Solar Market Insight Q4 2025” report from Solar Energy Industries Association (SEIA) and Wood Mackenzie, 85% of all new power added to the grid during the first nine months of the Trump administration came from solar and storage. And here’s the twist: Most of that growth – 73% – happened in red states.
Eight of the top 10 states for new installations fall into that category, including Texas, Indiana, Florida, Arizona, Ohio, Utah, Kentucky, and Arkansas. Utah jumped into the top 10 this quarter thanks to two big utility-scale projects totaling more than 1 GW.
But the report also flags major uncertainty ahead. Federal actions, including a July memo from the Department of the Interior (DOI), have slowed or stalled the approvals pipeline for utility-scale solar and storage. Without clarity on permitting timelines, Wood Mackenzie’s long-term utility-scale forecast through 2030 remains basically unchanged from last quarter.

“This record-setting quarter for solar deployment shows that the market is continuing to turn to solar to meet rising demand,” said Abigail Ross Hopper, SEIA’s president and CEO. She added that strong growth in red states underscores how decisively the market is shifting toward clean energy. “But unless this administration reverses course, the future of clean, affordable, and reliable solar and storage will be frozen by uncertainty, and Americans will continue to see their energy bills go up.”
Two new solar module factories opened this year in Louisiana and South Carolina, adding a combined 4.7 GW of capacity. That brings the total new US module manufacturing capacity added in 2025 to 17.7 GW. With a new wafer facility coming online in Michigan in Q3, the US can now produce every major component of the solar module supply chain.
“We expect 250 GW of solar to be installed from 2025 to 2030,” said Michelle Davis, head of solar research at Wood Mackenzie and lead author of the report. “But the US solar industry has more potential. With rising power demand across the country, solar could do even more if current constraints were eased.”

The spiritual successor to the beloved Chevy Geo Tracker, production of the new-for-2026 electric Spark EUV has officially begun in Brazil with more than 200 miles of range.
That’s right, kids. To know the Chevy Tracker is to love the Chevy Tracker. The tiny, top-heavy Suzuki-based SUV combined bold colors, fun styling, (relatively) good fuel economy, and real off-road chops (especially in ZR2 trim) with an affordable price tag to make the Tracker an early favorite among the serious rock-crawling crowds.
GM Brazil invested the equivalent of $73 million to get the PACE factory ready to assemble GM’s modern, zero-emissions Chevy crossover for the South American and Middle Eastern markets – an investment big enough to earn a visit from Brazilian president Luiz Inácio Lula da Silva, who was on-hand for the December 3rd kickoff event.

“It’s not a car factory,” said Comexport Vice President and PACE shareholder, Rodrigo Teixeir. “(The) goal is to develop technology there, not simply assemble a vehicle.”
Production of the new Spark EUV began last week, with production of the equally new Chevy Captiva EV set to begin as early as Q1 of 2026.
2026 Chevy Spark EUV
The Made in Brazil Chevrolet Spark EUV is heavily based on the Chinese Baojun, and is powered by that vehicle’s single 75 kW (101 hp), 180 Nm (130 lb-ft) motor driving the front wheels. Power comes from the Baojun’s 42 kWh LFP battery that, with regenerative braking, is good for up to 360 km (220 miles) on the NEDC driving cycle.

A federal judge on Monday struck down President Donald Trump’s sweeping ban on new wind power projects in the U.S., a major victory for an industry that has been singled out by the White House since the administration’s first day.
Judge Patti Saris of the U.S. District Court for the District of Massachusetts ruled that Trump’s ban is “arbitrary and capricious and contrary to law,” tossing out the president’s action in its entirey.
Trump issued a memorandum on Jan. 20 halting permits and leases for offshore and onshore wind farms, pending federal review. Saris said that federal agencies had failed to provide a reasoned explanation for such a drastic change in U.S. policy.
Seventeen states led by New York Attorney General Letitia James sued Trump in May to overturn the president’s ban. They argued that it created “an existential threat to the wind industry.”
“This is a big victory in our fight to keep tackling the climate crisis and protect one of our best sources of clean, reliable, and affordable energy,” James said in a post on social media platform X.
States in the Northeast and Mid-Atlantic in particular have been pursuing offshore wind projects to meet future energy demand as they seek to reduce carbon-dioxide emissions.
White House spokeswoman Taylor Rogers said in a statement that “offshore wind projects were given unfair, preferential treatment while the rest of the energy industry was hindered by burdensome regulations.”
