Perlight Black Grid solar panel review: best for long warranty
This Perlight Black Grid review explores why this panel is a top choice for homeowners seeking both long-term performance and an extended warranty. It's part of our expert-reviewed guide to the best solar panels for UK homes. If you're weighing up whether solar panels are worth it, this review — and our full guide to the best solar panel installers — will help you make an informed decision. The Perlight Black Grid solar panel stands out in a crowded market, not only for its sleek design and solid efficiency but for offering one of the longest warranties available. Choosing the best solar panels for your home involves more than just headline specs, especially as installation is often the most expensive part of the total cost of solar panels. That's why long-term durability matters. Commercial solar growth has driven significant tech advances in recent years. Many panels now offer similar specs on paper — comparable power output, 25- to 30-year lifespans, and sleek all-black designs. But with installation often being the largest part of the overall , and British weather posing its own set of challenges, the stakes for getting the right system are high. While solar panel prices have dropped dramatically, thanks in part to China's manufacturing scale and innovation, installation costs remain high due to labour, scaffolding, and system integration. So it's worth considering the total system cost, not just the price per panel, when selecting the best panel for your home. Why choose the Perlight Black Grid? Price, installed: £895 to £1,195 per kW Efficiency: 26 per cent Wattage per panel: 500W Type: N-Type Made in: China Degradation: 87.4 per cent after 30 years Warranty: 30 years Founded in 2006, Perlight is a Chinese manufacturer of solar panels with a long track record. Its Black Grid solar panel offers an impressive 30-year warranty — five years longer than the industry standard — making it ideal for those looking to maximise long-term savings and reduce replacement concerns. This longer guarantee can offer extra peace of mind, particularly if you're financing your solar panel system over time or plan to remain in your home for decades. That said, many panels rated for 25 years will likely keep performing beyond their warranty period. In terms of performance, the Perlight Black Grid solar panel also offers better efficiency and a higher power rating, delivering 500W per panel, than other solar panels on our list. While the degradation rate is slightly lower than other top-tier models, it still holds up well, retaining nearly 87 per cent of output after 30 years. The company is also somewhat shy about filing facts about itself compared to its competitors, although it passes all the necessary regulatory hurdles. One downside is that Perlight isn't a Tier-1 manufacturer, meaning it hasn't been ranked by BloombergNEF for financial transparency and bankability. However, it has a long track record and its global footprint — shipping to over 100 countries — and compliance with international standards suggest a reliable product. The panels also have high pressure resistance, meaning they should be able to withstand the bumps, bangs and weather that 30 years on a roof will throw at them. The panels are built with high pressure resistance, which should help them withstand the UK's often unpredictable weather over several decades. Like most solar panels on the market today, these are manufactured in China, which has invested heavily in clean energy production and now dominates the global solar supply chain. China's lead in silicon refinement and solar R&D means many of the world's best solar panels come from Chinese firms. While the cost of panels has fallen by about 90% since 2000, installation costs have risen due to labour and inflation, so total system cost still needs careful budgeting. Pros: Market-leading 30-year warranty High efficiency and power output Cons: A 30-year product warranty is hard to come by in any product but Perlight offers one of the longest warranties available in the market Paul Evans, head of renewables at solar panel fitter Glow Green How we compiled our guide To compile our list, we spoke to experts on the ground and have broken down the top-performing brands based on real-world value, not just technical specs. We've prioritised long-term performance, value for money, and the reputation of the best solar panel installers in the UK. And if you're wondering if solar panels are worth it for your home, this guide is designed to help you make a smart, informed decision that pays off over time, whether you're upgrading an old array or fitting solar panels for the first time. Most panels are guaranteed for 25 years and offer similar power output, size, efficiency and looks. So we've weighted our judgement towards cost and degradation, which describes how much power the cells will provide after a number of years. The higher the percentage, the better. Much of your decision will also depend on which installer you go with, as many have preferred brands they work with due to bulk purchasing. You'll also see a lot of unfamiliar Chinese names as you do your research, but many of these are Tier-1 manufacturers in clean energy with strong track records in quality and durability. Why trust us

Renewable energy is a lifeline for many U.S. farms, but Trump's cuts to wind and solar are putting that at risk
Drive through the plains of Iowa or Kansas and you'll see more than rows of corn, wheat and soybeans. You'll also see towering wind turbines spinning above fields and solar panels shining in the sun on barns and machine sheds. For many farmers, these are lifelines. Renewable energy provides steady income and affordable power, helping farms stay viable when crop prices fall or drought strikes. But some of that opportunity is now at risk as the Trump administration cuts federal support for renewable energy. Wind power brings steady income for farms Wind energy is a significant economic driver in rural America. In Iowa, for example, over 60% of the state's electricity came from wind energy in 2024, and the state is a hub for wind turbine manufacturing and maintenance jobs. For landowners, wind turbines often mean stable lease payments. Those historically were around US$3,000 to $5,000 per turbine per year, with some modern agreements $5,000 to $10,000 annually, secured through 20- to 30-year contracts. Nationwide, wind and solar projects contribute about $3.5 billion annually in combined lease payments and state and local taxes, more than a third of it going directly to rural landowners. These figures are backed by long-term contracts and multibillion‑dollar annual contributions, reinforcing the economic value that turbines bring to rural landowners and communities. Wind farms also contribute to local tax revenues that help fund rural schools, roads and emergency services. In counties across Texas, wind energy has become one of the most significant contributors to local property tax bases, stabilizing community budgets and helping pay for public services as agricultural commodity revenues fluctuate. In Oldham County in northwest Texas, for example, clean energy projects provided 22% of total county revenues in 2021. In several other rural counties, wind farms rank among the top 10 property taxpayers, contributing between 38% and 69% of tax revenue. The construction and operation of these projects also bring local jobs in trucking, concrete work and electrical services, boosting small-town businesses. The U.S. wind industry supports over 300,000 U.S. jobs across construction, manufacturing, operations and other roles connected to the industry, according to the American Clean Power Association. Renewable energy has been widely expected to continue to grow along with rising energy demand. In 2024, 93% of all new electricity generating capacity was wind, solar or energy storage, and the U.S. Energy Information Administration expected a similar percentage in 2025 as of June. Solar can cut power costs on the farm Solar energy is also boosting farm finances. Farmers use rooftop panels on barns and ground-mounted systems to power irrigation pumps, grain dryers and cold storage facilities, cutting their power costs. Some farmers have adopted agrivoltaics — dual-use systems that grow crops beneath solar panels. The panels provide shade, helping conserve water, while creating a second income path. These projects often cultivate pollinator-friendly plants, vegetables such as lettuce and spinach, or even grasses for grazing sheep, making the land productive for both food and energy. Federal grants and tax credits that were significantly expanded under the 2022 Inflation Reduction Act helped make the upfront costs of solar installations affordable. However, the federal spending bill signed by President Donald Trump on July 4, 2025, rolled back many clean energy incentives. It phases down tax credits for distributed solar projects, particularly those under 1 megawatt, which include many farm‑scale installations, and sunsets them entirely by 2028. It also eliminates bonus credits that previously supported rural and low‑income areas. Without these credits, the upfront cost of solar power could be out of reach for some farmers, leaving them paying higher energy costs. At a 2024 conference organized by the Institute of Sustainability, Energy and Environment at the University of Illinois Urbana-Champaign, where I work as a research economist, farmers emphasized the importance of tax credits and other economic incentives to offset the upfront cost of solar power systems. What's being lost The cuts to federal incentives include terminating the Production Tax Credit for new projects placed in service after Dec. 31, 2027, unless construction begins by July 4, 2026, and is completed within a tight time frame. The tax credit pays eligible wind and solar facilities approximately 2.75 cents per kilowatt-hour over 10 years, effectively lowering the cost of renewable energy generation. Ending that tax credit will likely increase the cost of production, potentially leading to higher electricity prices for consumers and fewer new projects coming online. The changes also accelerate the phase‑out of wind power tax credits. Projects must now begin construction by July 4, 2026, or be in service before the end of 2027 to qualify for any credit. Meanwhile, the Investment Tax Credit, which covers 30% of installed cost for solar and other renewables, faces similar limits: Projects must begin by July 4, 2026, and be completed by the end of 2027 to claim the credits. The bill also cuts bonuses for domestic components and installations in rural or low‑income locations. These adjustments could slow new renewable energy development, particularly smaller projects that directly benefit rural communities. While many existing clean energy agreements will remain in place for now, the rollback of federal incentives threatens future projects and could limit new income streams. It also affects manufacturing and jobs in those industries, which some rural communities rely on. Renewable energy also powers rural economies Renewable energy benefits entire communities, not just individual farmers. Wind and solar projects contribute millions of dollars in tax revenue. For example, in Howard County, Iowa, wind turbines generated $2.7 million in property tax revenue in 2024, accounting for 14.5% of the county's total budget and helping fund rural schools, public safety and road improvements. In some rural counties, clean energy is the largest new source of economic activity, helping stabilize local economies otherwise reliant on agriculture's unpredictable income streams. These projects also support rural manufacturing – such as Iowa turbine blade factories like TPI Composites, which just reopened its plant in Newton, and Siemens Gamesa in Fort Madison, which supply blades for GE and Siemens turbines. The tax benefits in the 2022 Inflation Reduction Act helped boost those industries – and the jobs and local tax revenue they bring in. On the solar side, rural companies like APA Solar Racking, based in Ohio, manufacture steel racking systems for utility-scale solar farms across the Midwest. An example of how renewable energy has helped boost farm incomes and keep farmers on their land. As rural America faces economic uncertainty and climate pressures, I believe homegrown renewable energy offers a practical path forward. Wind and solar aren't just fueling the grid; they're helping keep farms and rural towns alive.

This Plane Is Bigger than a 747. It Can Fly for Months on Its Own.
Here's what you'll learn when you read this story: Flying on solar power isn't easy, but the U.S.-based startup Skydweller Aero thinks they may have a winning design. Called the Skydweller, this autonomous drone sports a 236-foot wingspan laden with 17,000 individual solar cells, and is capable of flying for at least three months without stopping, thanks to its quadruple redundant flight software and 1,400 pounds of batteries on board. This isn't a play at cross-country sustainable flight—Skydweller Vero sees their aircraft as primarily a spy tool for loitering over conflict zones or other areas of interest. Decarbonizing various forms of human transportation has been a relatively straightforward process. Lithium-ion batteries packed inside electric cars deliver mileage per charge similar to gasoline-powered cars, and electric trains have been around for nearly 150 years. Flying, on the other hand, has been a bit more difficult. Turns out you need a lot of energy to keep things running in mid-air, and that can be quite the engineering challenge. It's a difficulty that's been thoroughly explored by solar-powered electric planes like Solar Impulse, which completed a piloted round-the-world flight back in 2016. And now, a new kind of a solar plane—called the Skydweller—is following in its footsteps. Although more of a drone than a plane (since it's designed to be autonomous), the Skydweller—built by the U.S. tech startup Skydweller Aero—contains 17,000 individual solar cells placed across its gargantuan 236-foot wingspan, which is wider than a Boeing 747 tip-to-tip. Of course, seeing as it has no human cargo, it's also 160 times lighter (thanks to its carbon fiber construction), and can carry only 2.5 metric tons at max capacity. In April 2024, Skydweller successful performed its first unmanned test flight at Stennis International Airport in Mississippi. 'This is a true, world-changing first in the aerospace industry,' Skydweller Aero CEO Robert Miller said in a press statement at the time. 'We are applying cutting-edge, 21st-century materials science, artificial intelligence, and software development to an industry that has spent more than 100 years building piloted, combustion-based aircraft.' While it sounds a bit like the main character from some schlocky Star Wars ripoff, the name is an apt one, as Skydweller isn't designed with human passengers in mind. Instead, Skydweller Aero sees its aircraft primarily as a surveillance machine, circling the sky and providing much-needed eyes over conflict zones or other areas of interest. Powered by the Sun, the company estimates that it can stay airborne for at least three months at a time—if not longer. To survive those long nights when the Sun isn't shining, the aircraft is equipped with 1,400 pounds of batteries, and it also drops to lower elevations, descending from its typical operating range of between 25,000 and 35,000 feet down to between 5,000 and 10,000 feet. Of course, power is only part of the issue—the Skydweller's aviation software also has to continuously run without error. According to Skydweller's website, the aircraft's vehicle management system maintains quadruple redundancy by using 'advanced self-healing algorithms within the VMS' to autonomously shut down, fix, and resurrect while the drone is in flight. The U.S. military has invested in a variety of surveillance balloons and blimps in the recent past. The Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System (JLENS), first requested in the late 90s, was meant to fulfill a similar role, but was effectively cancelled in 2017. Recently, the U.S. Army has worked with the private company Aerostar to develop spy balloons capable of staying aloft for a month (and were last seen not over a warzone, but instead the city of Tucszon, Arizona near the U.S.-Mexico border). No doubt the Skydweller would add another tool to that surveillance arsenal. Whether that's a good or bad thing remains to be seen.

Australia boosts underwriting scheme for renewables to meet clean energy target
SYDNEY, July 29 (Reuters) - Australia will expand the volume of solar and wind projects it underwrites in the race to stabilise an ageing power grid and hit a target of 82% renewable energy generation by 2030, the energy minister said on Tuesday. Energy Minister Chris Bowen said the Capacity Investment Scheme, the government's flagship program to boost private investment in clean energy projects, would be expanded by 25%. That will help underwrite an additional 8 gigawatts of generation and storage projects, taking the scheme's total coverage to 40 GW. "As our ageing coal-fired power stations only become more expensive and more unreliable we need new generation now," Bowen told the Investor Group on Climate Change. "Our energy grid's transition remains urgent," he added in an excerpt of a speech released to media. Analysts project Australia will fall far short of its goal of 82% renewable energy generation by 2030, thanks to inadequate investment and grid connection delays. Under the scheme, the government calls for competitive tenders and agrees floor and ceiling limits on project revenue, paying the difference if it falls below the floor, while sharing in profits if the ceiling is exceeded. The six tender rounds held since the scheme's 2022 launch were "consistently and massively" oversubscribed, said Bowen, who is also the minister for climate change. The declining costs of batteries and solar power gave the government an opportunity to "supercharge" the transition to renewable energy, he said. Underwriting an additional 5 GW of dispatchable capacity, such as batteries, is expected to support investment of A$21 billion ($13.7 billion). A further 3 GW of wind and solar projects is expected to help to power an additional 1 million households. ($1=1.5333 Australian dollars)
