    How much power yield can you really expect from your solar panels 10 years later?

    When Next Hydraulics planned the design and construction of their second production plant in 2008, their goal was to make the building energy self-sufficient.

    The company designs and manufactures mobile lifting equipment for the global market and is based in Boretto, Italy. As early adopters of clean power generation on an industrial site, they sought a system that could convert sunlight to usable electricity and offer some level of autonomy from the energy distributed through the grid.

    The result was the installation of a photovoltaic (PV) system comprising 481 SunPower Maxeon rooftop solar panels. And according to the company, the system continues to produce a higher energy yield 14 years later than initially estimated.

    Dependable solar panel performance over time

    It had long been a priority of Next Hydraulics CEO Oreste Masetti to invest in clean energy and a system that would produce as much peak power as possible and dependable performance over time.

    Like any industrial equipment, installing a PV system is a major investment and should deliver savings. Hence reliability and energy yield of solar panels are essential deciding factors.

    To achieve their vision, Next Hydraulics engaged the services of Project Group, an expert in installing residential and industrial photovoltaic systems since 2006. A SunPower Premier Partner, Project Group has installed more than 400 industrial PV systems, attesting to the quality of SunPower Maxeon modules in the field.

    Higher-than-expected energy outputs

    At the Next Hydraulics production site, 481 SunPower Maxeon panels were installed on a surface area of 742 sqm. The system design took advantage of every available space in the roof pitches with southern exposure.

    much, power, yield, really, expect, your

    Using SunPower Maxeon modules allowed Project Group to install 108 kWp in total, about 30% more than the conventional technology available at the time, using the same space.

    According to Next Hydraulics, the modules have produced an average of 1204 kWh/kWp in the last five years. This is higher than what the modules produced in their first years following installation. Not one single module has been replaced since the panels were installed in 2008.

    Yearly output of the SunPower solar installation on Next Hydraulics rooftop over a decade.

    Solar energy contributes to more predictable production costs

    Minimal maintenance of the panels and a continuous power supply are critical to Next Hydraulics’ operations, which rely on automatic painting equipment running nonstop inside the production plant.

    According to the company, the solar system benefits production for two reasons: it guarantees an autonomous energy supply for round-the-clock operations and using PV-generated energy allows for stable and predictable production costs.

    For Next Hydraulics, the choice to invest in photovoltaics in 2008 was an economic and ecological decision. The constant solar power output over time has resulted in more significant payback from the panels and, therefore, reduced energy costs. And the move to clean energy generation aligns with the company’s vision to reduce its impact on the environment.

    Thanks to the superior performance in terms of yield and energy efficiency of SunPower panels compared to competing products, we were able to achieve our goal. I would advise other company directors to invest in a PV system for every newly constructed building and whenever work is done on existing buildings for renovations, re-roofing, [or] energy upgrades. This move toward a more sustainable future allows us to reduce energy costs and be as self-sufficient as possible.

Each of them has its own potential and its own characteristics that they define through their products. A comparison has been listed down below, which defines both companies.

    Jinko Solar Panels

    Jinko is the largest producer of solar panels in the globe. Jinko supplied over 14GW last year, which is almost 7 times the total market for systems with 100kW or less in Australia.

    Massiveness: There are no bigger than Jinko. They transport more than anyone else on the planet.

    Range: If you want to install solar panels, you will have many choices, thanks to Jinko’s wide selection and numerous distributors.

    Price: One of the more affordable solar panel brands among the selection of reliable solar makers is Jinko.

    Manufacturer: Jinko Solar is not a diverse manufacturer. They are also relatively recent (2011).

    Performance: Nothing problematic with this as Jinko produces adequate panels. Some of them are superior to others in their price bracket, but they are volume producers, not performance panels.

    Build Process: Jinko purchases cells for their screens from a variety of sources. They purchase from various sources in order to achieve the enormous volume that they do possess. Although, better quality control can be provided by a vertically integrated company.

    SunPower Solar Panels

    Maxeon still has sights set on U.S. solar manufacturing hub

    Maxeon Solar Technologies, the solar panel manufacturing spinoff of installation company SunPower, has a complex American origin story, but its modules aren’t especially popular in the United States. The organization is trying to change that by increasing production at its Mexican module assembly plants and scoping sites for a U.S. manufacturing hub. The demand is there, said Maxeon CEO Jeff Waters in an exclusive Solar Power World interview, but of course everything is dependent on U.S. trade laws and climate legislation.

    Since the split from SunPower in 2020, Maxeon has only had access to the U.S. residential and small commercial market through its exclusive supply agreement with SunPower. Through the end of 2022, SunPower dealers can only install Maxeon panels and Maxeon can’t work with any other U.S. residential installers. Beginning in 2023, Maxeon will have the ability to sell products into the residential market and SunPower will have the option to source non-premium panels from other manufacturers.

    In the utility-scale market, Maxeon has mostly been shut out due to its Chinese manufacturing partners. When Maxeon set out on its own, it received an investment from Chinese silicon wafer manufacturer Tianjin Zhonghuan Semiconductor Co. Through the joint-venture, Maxeon has a steady supply of wafers and the ability to assemble modules nearby. That Chinese involvement has made Maxeon’s entrance into the U.S. utility-scale market difficult.

    “By virtue of them being produced in China, we really couldn’t sell them into the U.S. because of tariffs and AD/CVD, so we’ve been excluded from the U.S. market,” Waters said. “Soon after we spun off, we started looking into the potential for us to build a panel for that Performance series that could go into the U.S.”

    much, power, yield, really, expect, your

    Maxeon has two product families: Maxeon solar panels for residential and light commercial, and Performance solar panels for cost-sensitive markets and utility-scale installations. The Maxeon panels use interdigitated back contact (IBC) technology and are the premium panel class that SunPower installers are familiar with. The Performance line uses shingled, mono-PERC cells and has a bifacial offering.

    To get the Performance panels into the U.S. utility-scale market, Maxeon shifted production of PERC cells to its Malaysian facility and expanded its module assembly capacity at its plant in Mexicali, Mexico, to 1.8 GW. Taking production out of China has already led to major U.S. supply contracts: Cypress Creek has agreed to take 300 MW, Origis Energy and Total Energies both signed for 400 MW each and the nearly 1-GW Gemini project outside Las Vegas will use Performance panels.

    “This gives us a great avenue into the U.S. that allows us to sell cost-competitively and avoid a lot of the tariff issues,” Waters said. “We found there is a huge appetite to work with a Nasdaq-listed, public company that has more traditional Western business practices when it comes to long-term contracts and business dealings. We’ve had an immense amount of demand for product coming out of [Mexico].”

    Greater volume in Malaysia and Mexico was Phase 1 of Maxeon’s U.S. plans. Phase 2 is opening a 3-GW cell and module manufacturing plant in the United States. The company first announced the U.S. manufacturing plans in early 2021 and has been waiting on favorable legislation (like the Solar Energy Manufacturing for America [SEMA] Act) to pass through Congress ever since.

    “When we calculated the cost increase due to producing in the United States — and it’s not just labor, it’s everything from infrastructure to energy costs — you need those incentives that were in SEMA to justify producing in the United States, otherwise the cost delta is just far too much,” Waters said. “For us, we want to go big in the United States — 3 GW. Doing that in the United States would be a shot in the arm for the solar supply chain. We know there’s activity going on with others trying to get into ingot wafering and other parts of the supply chain, so we hope that we can be a part of building this tidal wave to get a supply chain back up and running here in the U.S.”

    Maxeon has also applied for a Dept. of Energy loan through the Energy Policy Act of 2005 Title XVII program. The DOE loans, which have previously gone to “ground-breaking” projects like early utility-scale installations, stipulate the recipient be working with new or significantly improved technologies. Maxeon is complying with that requirement with its next-generation product that Waters said is “a new technology that’s not done in China or broadly across the [other solar panel brands].” Specifically with Maxeon 7, the company is innovating back-end metallization processes.

    “We’ve told the DOE we’re waiting on SEMA to come through. If they come through mid-year, we’re aggressively prepared. We’re already doing final site selection and looking at how to construct the plant as fast as we can,” he said. “If it were mid-year 2022 approval on SEMA and the DOE loan guarantee, you would see us being in production early 2024.”

    The U.S. factory would likely set up in the Southeast to serve the eastern side of the country while the Mexicali facility will continue to supply the West.

    Until then, Maxeon continues its global reach. It released the thin, frameless, glassless solar panel Maxeon Air to the European market and bumped its performance warranty outside the United States to a 40-year guarantee. Success in Europe, Asia and Australia could eventually lead to the U.S. market — ultimately where Maxeon wants to be a leading player.

    My experience with Mexican made electronics and auto parts is they are inferior quality products. It makes me hesitant about them and might just use Q Cells instead on my current project.

    Is Maxeon considering making futher supply chain changes (cell supply) due to the AD/CVD Auxin petition investigation? I find the timing of this article rather ironic, due to the fact that these potential 50-250% duties will hurt any module manufacturer sourcing cells from SE Asian named countries.

    I’m still trying to confirm whether or not Maxeon uses Chinese parts. While they weren’t named in the suit, it appears that they do. Their defense is that they have premium pricing. That’s not what the suit is about.

    The future of solar lies beyond the panel

    Since the world first began to confront the realities of climate change, our relationship with energy has been rapidly shifting. A growing FOCUS on the climate and cost-of-living crisis, coupled with the ongoing conflict in Ukraine and increasing supply chain pressures, has highlighted the fragility of centralized, fossil-based energy sources. Around the world, freedom from these traditional energy sources is top-of-mind, and as energy costs continue to climb, people are looking for alternatives that provide financial savings, energy security, and climate stability.

    As a leader in the solar industry, we are already helping to deliver the tools to transition away from a fossil-fuel based economy. While not all countries and communities have the ability to support hydro or wind power, most countries have much more photovoltaic potential than their current electricity demand requires. Every household that can support solar panels should be able to do so if they wish.

    At Maxeon, we have been engineering and manufacturing the high-efficiency solar panels that capture this energy for over 35 years. While we know that well-made panels are the foundation of the global solar industry, as a business, we need to go further to empower more people to produce their own energy and contribute to positive change.

    From the Roof into the Home

    The release of our 40-year warranty on our Maxeon Line solar panels at the start of the year was a foundational step in beginning this process. Giving consumers panels that can reliably supply them, their home, and their families with green energy for a generation is crucial if we are to unleash solar’s potential. However, many of the challenges consumers face when going into solar lay in the buying journey and system experience.

    That’s why, in the run-up to Intersolar Europe 2022, we announced SunPower One, a new solution aimed at simplifying the adoption of clean energy and addressing some of the key pain points customers face. What does this mean? Reaping the benefits of solar power can now be as easy as flipping a light switch, and in turn, accelerating the clean energy transition.

    Going Beyond the Panel

    We view our industry-leading solar panels as a “door-opener” for customers, the first step in their journey towards energy independence. Through this door lies an opportunity to guide consumers through a multi-generational relationship with their energy, and we are delivering this through an open, flexible ecosystem of category-leading partners. SunPower One is the first step in this journey. than a fragmented system of clean energy components, it is an integrated home energy management solution. It reimagines the consumer experience, keeping homeowners informed with actionable energy insights within their households that help lower energy costs and emissions. Over time, through artificial intelligence, it learns about a homeowner’s pattern of electricity consumption and can identify categories of devices or appliances. With this contextual information, it suggests tips to use them more efficiently, like using them during periods of high solar production or switching them off when electricity are high.

    At launch, Maxeon’s SunPower One experience will be exclusively available with Maxeon’s new SunPower Reserve all-in-one storage offering. Over time, Maxeon’s SunPower One ecosystem will grow and incorporate additional products in categories like electric vehicle charging, as well as software integrations and value-added services designed to expand the customer experience.

    At Maxeon, we believe we have a responsibility to play a bigger role in the clean energy transition, because of our panel leadership, our channel reach, and our lack of “technology debt.” This great advantage means we have the freedom to think outside the box and leverage next-generation technologies to accelerate the democratization of energy production.

    We are eager to welcome new partnerships with category leaders across the industry that will help empower our end-customers to drive more energy savings.

    Our Changing Relationship with Energy

    Powering Positive Change TM around the world, as we enter an age of renewed intensity in the Net Zero transition, will rely on providing customers the tools they need to become energy independent. Residential energy solutions are a key piece of the puzzle, but we cannot do it alone; policy interventions such as the UK government’s decision to reduce VAT on domestic solar panel installations and the council of the European Union’s directive allowing for as much as 0% VAT on solar panels, need to be replicated around the world to drive direct attention towards the need for and advantages of solar. Measures from the recent RePowerEU strategy from the European Commission, such as the European Rooftop Solar Initiative, which would see rooftop solar becoming legally binding on certain buildings symbolise the kind of ambition which is needed.

    Solar is critical when it comes to reducing our dependence on fossil fuels, and gaining energy security and independence. We believe doing everything we can to improve access to this genuinely revolutionary technology and in turn, altering the customer experience so that the barriers to enjoying the value of solar are withdrawn and change the world.
