Innovations in Solar Panel Technology You Should Know About
The importance of solar energy in the fight against climate change cannot be overstated.
Although improvements have been made in solar panel technology, conventional silicon-based solar cells generally achieve an efficiency rate of approximately 15-20%. This means a large portion of the sunlight they capture is wasted.
The latest technologies in solar panels for homes are pushing beyond traditional silicon cells to increase efficiency, flexibility, smart integration, and new applications.
The global demand for clean energy is growing, and we need solar panels that can generate more power from less space. Improved efficiency means that we can produce more electricity without requiring large land areas, which is especially important in densely populated or urban environments.
Cost is one of the most significant barriers to the widespread adoption of solar energy. While the cost of solar panels has decreased dramatically in recent years, there is still room for improvement.
In this blog, we will examine some of the most recent innovations in solar panel technology.

World's largest electric carmaker BYD accelerates expansion drive in Africa
Chinese electric vehicle giant BYD is accelerating its expansion in South Africa, plans to triple its dealership network by 2026 and solidify its position in Africa's largest automotive market. BYD is expanding rapidly in South Africa, aiming to triple its dealerships by 2026. The company launched operations in South Africa in 2023 with the ATTO 3 electric vehicle. New energy vehicle (NEV) sales in South Africa doubled to 15,611 units in 2024. The world's largest electric vehicle manufacturer, BYD is aggressively expanding its presence in South Africa's rapidly evolving new energy vehicle (NEV) market, where it faces intensifying competition from other Chinese brands such as GAC, Chery, and Great Wall Motors (GWM). The automaker, which launched in South Africa in 2023 with its BYD battery electric ATTO 3 vehicle, currently operates around 13 dealerships nationwide. According to Steve Chang, General Manager of BYD Auto South Africa, the auto company plans to significantly expand its presence: " By the end of the year, we will have about 20 dealerships around the country, and we aim to grow that to around 30-35 by next year." In an interview with Reuters, Chang said that the expansion will help BYD become a familiar and trusted name as South Africa transitions to electrified vehicles. New models, improved sales in SA As part of its dual-powertrain strategy, the automaker introduced three new models in April: the plug-in hybrid Shark pick-up, the hybrid SEALION 6, and the fully electric SEALION 7 SUV, bringing its total South African offerings to six models that cover both hybrid and battery electric vehicles. Industry figures reveal growing local interest in new energy vehicles (NEVs). According to the National Association of Automobile Manufacturers of South Africa (NAAMSA), NEV sales more than doubled in 2024, reaching 15,611 units, up from 7,782 in 2023. Although NEVs still account for a small fraction of total vehicle sales, the significant growth highlights a shifting consumer mindset that BYD is positioning itself to capitalize on. Regarding the current market landscape, Chang stated, " While the share of NEVs to total car sales is still low, BYD is hoping to capture the market early on, in preparation for a meaningful transition' He further emphasized, " We want to educate and cultivate the market of South Africa and make sure that the South African consumers can catch up with the rest of the world ' Despite the momentum, challenges persist. Limited charging infrastructure, unreliable electricity supply, and higher import duties on electric vehicles compared to traditional combustion-engine cars continue to slow down EV adoption across the continent. However, the Chinese auto giant remains optimistic. 'South Africa is one of the most important automotive markets in the southern hemisphere—and probably the biggest in Africa,' said Chang. 'So it's a market that we have to look at and see how we can develop the market," Chang added.

Apple's two biggest problem areas ahead of its WWDC 2025
Ahead of Apple's (AAPL) 2025 Worldwide Developers Conference kicking off this Monday, June 9, Needham analysts downgraded the iPhone maker from a Buy rating to Hold while removing its price target on the tech stock. Needham & Company senior media and internet analyst Laura Martin — the analyst behind the call — examines several of Apple's biggest problems as it faces pressures in China's consumer market and the team-up between OpenAI and former Apple designer Jony Ive. Here's a look at what to expect from the 2025 WWDC event. To watch more expert insights and analysis on the latest market action, check out more Morning Brief here. Let's take a look at Apple here. It's down 19% year to date, the lowest performing member of the magnificent seven and trailing the S&P 500, which is now up for the year. Ahead of Apple's company, uh, Worldwide Developers Conference, Needham and company cut its Apple rating from buy to hold and removed its $225 price target for the stock. We've got the person behind that call, Laura Martin, Needham and Company senior media and internet analyst joining us now. Really appreciate you making the time to break this down for us, Laura. What was the single biggest driver behind this call on Apple? So I think, I think we're focusing on two things. There's like an urgent problem for Apple and then an important problem for Apple. The urgent problem is, a, it's really expensive today at 26 times next year's earnings, which is twice its normal multiple over the last 10 years, and about a 25% premium to the S&P 500. So it's too expensive. Second, there are real risks to their fundamentals over the next 12 months. Not only tariffs, but, um, but also like the Chinese demand, which used to be 19% of their total iPhone sales, went to 17% last year. We expect it to go to 15% of total sales this year. So there, um, there really is issues with the rising nationalism in China and Chinese, uh, consumers buying competitive products and not Apple products. Um, also, we have risk of fundamentals services revenue because you may have seen that epic, uh, the epic court decision, which allows all these apps to actually get direct payment and not pay the Apple 30% tithe on, on these app payments. So that actually threatens services revenue. Anyway, lots of fundamental risks, um, coming from the outside world in the near term, again, to their fundamental earnings per share, a risk in addition to just tariffs. And the important problem here that isn't as urgent, but it is really important is competition. So what's happening is generative AI is opening up the possibility of replacing the smartphone with, if you think meta and Google are right, glasses, like these Ray-Ban glasses that Meta's already sold a million units of. Or, more importantly, um, Jony Ive, who used to was actually the designer behind every major Apple product on the market today, he was at Apple for 27 years, has recently, his company's been bought by Sam Altman's OpenAI, and they're talking about a new form factor that isn't a smartphone and it isn't glasses, but it's going to compete and replace, I mean, I think over the long term replace the iPhone because Jony Ive, who invented the iPhone as a design fact, uh, hardware, said he doesn't like screens. He wants to move consumers away from screens, which would be lovely if you could have a conversation with a 15-year-old where they weren't looking at their screens. So I'm completely supportive, but all of this is a competitive is a competitive threat to the largest iPhone maker, you know, the largest smartphone maker in the world.

The only ‘Made in America' smartphone maker has a message for Apple about manufacturing in the Trump tariff era
Todd Weaver has an important message for Apple as it faces growing demands by President Donald Trump to reshore some of its smartphone production: Don't listen to the conventional wisdom. Experts have long said that manufacturing iPhones in the U.S., rather than Asia, as Apple does, would be logistically impossible and ridiculously expensive. But Weaver argues companies can indeed do it successfully, and at a similar or only slightly higher cost—if given several years to navigate the inevitable complications. Weaver should know: His startup, Purism, is among the few, if not the only business, that assembles smartphones in the U.S. In fact, the U.S. pedigree is the main selling point of his company's Made in America device, the Liberty Phone. 'It is challenging to do this in the U.S.,' Weaver acknowledges. 'It's probably the reason I'm the only one.' And yet, he says his company has managed to make it work and has been profitable for the last two years—a real world example of what's possible on a hot-button topic in which political talking points and vested interests often dominate the debate. President Donald Trump recently put U.S. smartphone production in the spotlight as part of his global trade war. On May 23, he used social network Truth Social to publicly attack Apple for importing iPhones into the U.S., rather than making them domestically, and then threatened the company with a 25% tariff if it continued to do so. Whether any of the import taxes will become permanent is unclear given Trump's whiplash decision-making and court challenges by third parties. Still, Apple has long assembled its iPhones overseas, mainly in China, and has resisted relocating any of that production to the U.S. In April, when Trump announced his tariffs, Apple went so far as to shift the sourcing of most U.S.-bound iPhones to India, which faced lower import taxes. U.S. assembly was never publicly mentioned as a possibility. In the past, Apple CEO Cook explained the reluctance by saying the abundance of skilled labor and top-notch suppliers overseas would be difficult to reproduce at home. Weaver's company, of course, is no Apple, which has sold more than 2 billion iPhones globally since introducing the first models in 2007. The devices unleashed a new era in the tech industry in which mobile devices became the prime focus. Purism, in contrast, has sold just tens of thousands of phones since debuting its first model in 2018, according to Weaver. And the company is barely-known outside the world of tech nerds. Its Liberty Phone, manufactured near San Diego, comes with U.S.-made electronics installed on a metal chassis from China. It retails for $1,999. Another phone, the Librem 5, is mostly the same design, except it's made in China with Chinese parts, and costs $799. The company also produces tablet computers, laptops, and servers. Purism pitches its Made in America device as more secure and privacy friendly than those from major manufactures like Apple. Because all the critical parts and assembly are domestic, it's easy to verify that they haven't been tampered with by a foreign adversary that wants to snoop or stuff them with explosives. The phones also run on a Linux-based open source operating system. Anyone with technical know-how who is worried about the security can review the code—unlike with more popular phones, which come with operating systems that can't be easily inspected. Additionally, Purism's phones come with three kill switches that lets users physically disconnect their device from cell service, Wi-Fi and Bluetooth, along with its microphone and camera. When turned on, the switches sever the electrical circuit to the features they control and make it impossible for them to be accessed by hackers, Weaver said. Toggling on Airplane Mode, as users often do on more mainstream phones, is less secure, he said, because it's a purely software feature that doesn't cut power to the device's chips. Customers who are especially security conscious can pay extra to have their devices shipped with 'tamper evident tape' on the packaging, among other options, to flag any monkey business during transit. Purism's biggest customers are government agencies, many of which require high security, and individual consumers. The company's clients, Weaver said, include the FBI and the House Select Committee on Intelligence. Weaver said the cost of manufacturing the Purism's two phones is largely the same, despite one being made overseas and the other domestically. The phone that's made in China costs around $600 for parts, manufacturing, and assembly while the U.S.-made one comes in at $650. 'Producing goods in China vs. the U.S. is the same plus or minus 10%,' said Weaver, based mostly on automation. The difference between what Purism charges customers for its two phones is partly due to the higher profit margin the company collects for its U.S.-made device. People who want stronger security are often willing to pay extra for it, Weaver said. It also covers the extra overhead from some customers wanting to verify that Purism's supply chain is secure and the small additional cost of U.S. manufacturing. Purism's assembly line is in Carlsbad, Calif., where up to a dozen workers put together devices. The area is home to a pool of skilled labor thanks to the local defense industry and manufacturing for other mobile carriers. That relatively modest assembly line is a major contrast to the factories that make iPhones, operated by contract manufacturers, mostly in China. Those facilities can be the size of several football fields and employ over 100,000 people who work around-the-clock shifts. Weaver said the U.S. is at a huge disadvantage to China when it comes to skilled workers, who make up a significant part of the workforce in smartphone factories. The only way to reverse the shortage and lay the groundwork for companies to reshore their production is to encourage more people to learn skills that are useful in the manufacturing process, he said. 'If you go over to China you can find buildings and buildings of thousands of electronics engineers. If you look here, you can find maybe five total,' Weaver said. Apple, for example, would risk a catastrophe if it suddenly, in 2026, needed to ramp up staffing in the U.S. to produce millions of iPhones, he said. Training enough people for such a massive undertaking would take years. Weaver said Purism, founded in 2014, took several years to develop its domestic supply chain. The company's small size means it only needs limited quantities of components, which makes it impossible to achieve the economies of scale that come from producing huge numbers of devices. Manufacturing in the U.S. also comes with higher labor costs than in China. But with the help of automation, those extra costs can be kept to a minimum by reserving human labor for tasks performed after production is complete, such as soldering, assembly, repairs, and testing. Apple, on the other hand, would need vast amounts of components to keep its assembly line humming. While the company would likely be able to cut deals with domestic suppliers for most iPhone parts, some, such as high-quality cameras, may be impossible to quickly source in the U.S. and it would therefore have to import them, Weaver said. One analyst has said iPhones could end up costing $3,500 if made in the U.S., to account for the extra costs and hassles. Weaver agrees that it would cost Apple substantially more to produce iPhones in the U.S., if it had to move production quickly. But given enough time, Apple could substantially reduce the cost after developing a new supply chain, finding enough workers, and by relying on extensive automation. For Apple, opening a domestic manufacturing plant would therefore need to be a years' long process, Weaver said. That's why he criticized Trump's tariffs for taking effect almost immediately. Yes, many of those tariffs have since been delayed. But the takeaway for businesses is that they can't plan ahead. And yet, that's exactly what's required for something as complex as shifting manufacturing to the U.S. Trump's tariffs would be far more effective if phased in over many years, Weaver said. In that scenario, companies would have a clear and increasing incentive to reshore production—without being punished right off the bat. Weaver argues his U.S. manufacturing effort is already paying off and that it will gain momentum over time. He hopes the recent scandal involving U.S. officials using the chat app Signal to discuss a military strike against Yemen, and then accidentally inviting a journalist to join them, will help lift sales by encouraging the federal government to focus more on security. Weaver wouldn't get into the specifics of Purism's financials other than to say it has millions in annual revenue and turned profitable in 2023. The Liberty Phone is its biggest seller. Wayne Lam, an analyst with market research firm TechInsights, gave a mixed take on Purism's prospect. In an email, he said: 'They can be a successful niche player, but the odds of success are lower thanks to the bigger brands. They won't be able to compete in the consumer market but government/enterprise/military are all niche markets they can address.' To fund the expansion of his business, Weaver is trying to raise additional investment after taking in $16 million in funding over the years. Some of that money would go to fixing a shortcoming with his phones. Because they don't use Apple's iOS or Google's Android operating systems, they are incompatible with many of the most popular mobile apps like Uber. To get such apps work on its devices, Purism must make technical tweaks for each one. Purism can at least claim one small advantage over the giant companies that dominate the smartphone industry. If Trump's tariffs become permanent, it won't feel much impact from its U.S.-made phone, while the big players and their foreign-made devices could be hammered.
