    SunPower solar panels review 2023: Maximum efficiency

    Stories of big companies that start with one scientist conducting experiments in a lab are special. They are inspiring in how they prove the importance of creativity, hard work, and devotion to the craft. The story of SunPower, the manufacturer of the most advanced PV modules in the world, is like this. Learn more about the brand and its product in our SunPower solar panels review.

    SunPower history: Silicon Valley breakthrough

    Stanford, California, 1985. Richard Swanson, an electrical engineering professor at Stanford University, experiments with solar cells in the lab. His tests go so well that he breaks a record for cell power efficiency. This inspires him to take a sabbatical and start a solar company that he names Eos. Then it will change its name to Sunpower and become a company with the most efficient solar panels in the world.

    Richard Swanson is credited for creating Swanson’s law,an observation that solar cell decline by 20% for every doubling of solar panel industry capacity.

    Almost 40 years later SunPower is still headquartered in Silicon Valley. Richard Swanson retired in 2012 but remains on the advisory board. The company provides solar systems and batteries, primarily for residential customers. Technically, SunPower doesn’t make panels anymore since it spun off this part of its business in 2020 as Maxeon Solar Technologies in Singapore, but we’ll look at their products as if it is one company.

    SunPower technologies: Shingled design

    American engineers use a wide range of modern technologies to drive up the output of their solar cells. One of the most impressive examples is shingled design.

    To make a shingled solar panel, engineers slice cells into several strips and overlay them to create an electrical connection between them. It’s a bit like laying shingles on a roof. A shingled solar panel doesn’t need busbars or thin metal connectors. The panel gets a more uniform look and becomes more durable.

    The best thing about shingled design is the way it improves the shading tolerance of a panel. Cells in a standard panel are connected in series which means that their performance depends on one another. Shingles are connected in parallel which makes them independent. In general, a shingled solar panel is 40% better at fighting shading than a standard panel.

    Making shingled solar panels is difficult and expensive which is why so few manufacturers use this design — the only one that immediately comes to mind is Solaria.

    SunPower Maxeon panels: Efficiency no matter the cost

    SunPower Maxeon offers monocrystalline panels primarily for residential projects. There are high-output PV modules and bifacial panels but they aren’t the main FOCUS of a company. The brand also experiments with thin-film panels: for example, Maxeon Air is a highly anticipated flexible panel for home that should come out soon. Besides, SunPower designs solar systems and offers energy storage solutions

    SunPower solar panels for home reach the highest conversion rates that are possible at the moment. The panels are just shy of 23% efficiency. If your space is limited and your energy needs are high, high-efficiency panels are what you need.

    SunPower Maxeon always takes top places in rankings like “Top-10 solar panels” and “Best manufacturers”. The customer reviews for their panels are overwhelmingly positive which shows how stringent quality control is in the company.

    The quality and efficiency of SunPower Maxeon panels come at a cost. They are undoubtedly among the most expensive on the market, if not the most expensive ones. They cost from 1.5 to 3 per watt in the US before installation. When you include labor, shipping and equipment expenses, a system made with SunPower panels can cost 5 per watt or more.

    SunPower warranties: Up to 40 years

    The warranties from SunPower Maxeon deserve a special mention. The brands offer 40-year coverage for their products which is something that no one else does. The engineers claim that you are 100 times more likely to return a standard solar panel than the product from SunPower Maxeon.

    The coverage includes repair, replacement or refund for any defective panel for 40 years, including the removal, shipping and installation. It also covers the performance of a panel: the panel retains 88.3% by the year 40. There are nuances though:

    The warranty applies for the SunPower Maxeon product line. SunPower Performance panels get a standard 25-year warranty for product and performance. The 40-year warranty is only available to customers in certain countries. Luckily, the USA is on this list. Customers in Austria, Czech Republic, Denmark, Luxembourg, Malta, Portugal and Sweden are also eligible. Your system has to be registered. Otherwise, it is covered by a standard 25-year warranty.
