A solution for your roof that is very difficult to match
- The solar panel is not just another item.
- It's what determines everything.
- It's the core of the system.
All solar panels look the same. An aluminum frame, a color that's more or less dark. This makes you think that all panels work the same way...
But that's not true.
The real difference, the one that determines the energy you'll produce for the next 30 years, isn't visible, it's inside the solar panel.
Now, with your request you will be able to download the tool that no other company can offer you, the "Solar Solutions Comparator", with a list of what you should keep in mind to make your decision.

Enjoy the energy and savings of an extra panel at no cost and maximize the performance of your roof for three decades.
The payback period for solar panels for a home is typically between 6 and 10 years. Once you recover your investment, which must take into account the installation cost, energy consumption, and available grants, deductions and subsidies, the panels continue to generate clean energy. And this is where the panel quality becomes crucial to maximizing your long-term benefit.
- Although panels like SunPower Performance may have a higher initial cost, their value is superior and gives you absolute certainty about your future savings.
- Production and Durability: They guarantee a longer lifespan with a triple 30-year warranty, far exceeding the 12-25 years of standard panels.
- More Guaranteed Production: Their low annual degradation rate (maximum 0.40%) ensures that these panels will produce more energy for longer, maintaining 87.4% of their performance at 30 years
- A homeowner and/or business owner looking for a long-term investment to increase the efficiency and value of their property.
- A person who values the security of knowing their solar installation is protected by extensive warranties and professional installation.
- A conscious consumer looking for a sustainable and efficient solution, designed to respect the environment from start to finish.
- Someone who prioritizes quality and efficiency over price, seeking maximum performance without compromise.

Hello, I'm Frederic Andreu, Chemical Engineer from the Sarrià Chemical Institute (IQS) and postgraduate in renewable energy from the Polytechnic University of Catalonia (UPC).
For 10 years I worked at Endesa Energía, first managing large industrial accounts and later as head of solar energy for Spain. Currently, I am a managing partner at SolarTradex and I am passionate about developing and sharing this project.
Have you ever heard that houses are not started with the roof? Well, for engineers, when we talk about solar energy and energy self-sufficiency, it's exactly the opposite. And that's because, precisely on the roof, is where solar panels, the key element of self-consumption installations, transform sunlight into the electricity that will power your life.
And not knowing this can cost you a lot of money.

Frequently asked questions
What makes SunPower Performance panels superior to other panels?
SunPower Performance solar panels stand out for their advanced technology and robust construction. Their key features include:
- N-type TOPCon cell technology: they use silicon doped with phosphorus, with a special layer that reduces energy losses.
- Shingled cell design: the cells overlap to make the most of the panel's surface, and in case of partial shading, the panel continues to produce energy in other areas.
- Flexible connections: they prevent the cells from breaking or microfissures from forming, a common problem in other panels caused by temperature changes.
- Glass-glass construction: they are extremely resistant to hail impact, moisture and fire. It also allows energy generation on both sides (bifacial).

Are SunPower Performance solar panels resistant to hail and storms?
The SunPower Performance solar panels offer extreme weather resistance, well above the usual standards of the sector. Their glass-glass construction and POE encapsulant provide them with exceptional durability against the most adverse conditions:
- Hail: certified to withstand impacts of up to 45 mm in diameter, more than double the market average.
- Aggressive environments: highly resistant to dust, sand and salt mist, ideal for coastal areas such as the Balearic Islands or the Catalan coast.
This durability is backed by the manufacturer's 30-year warranty. Check all the features on our SunPower Performance panels page.
How do shadows affect energy production with SunPower Performance panels?
One of the main problems with conventional solar panels is that partial shading can drastically reduce the production of the entire panel. SunPower Performance panels minimise this effect thanks to their shingled cell architecture (tile-type).
How the shingled advantage works:
In a conventional panel, cells are connected in series through busbars and bypass diodes grouped in large blocks. If a single cell is shaded, the entire block drops to minimum. You can lose up to 60-70% of production with a small shadow.
In a SunPower Performance panel, the cells are arranged in overlapping strips (shingles) with much more segmented bypass. When a part of the panel is shaded:
- Only the production of the specific area affected by the shadow is lost.
- The rest of the panel continues producing at full capacity.
- The overall loss is limited to the actually shaded area, not the entire panel.
This architecture makes SunPower Performance especially recommended for rooftops with obstacles (chimneys, antennas, adjacent buildings) or with partial hourly shadows, where other brands would see their performance drop significantly.
Discover all the features on our SunPower Performance panels page.
What is the warranty for SunPower Performance panels?
SunPower Performance panels are covered by a 30-year warranty, one of the most solid in the solar sector. It includes three complementary coverages:
- Product: covers any manufacturing, material or workmanship defect for 30 years.
- Performance: SunPower guarantees the maintenance of performance throughout the three decades, well above the market average thanks to the panel's low annual degradation rate.
- Service: extensive coverage for panel repair and replacement, with agile process management when necessary — something that standard warranties from other brands do not include.
The data supports the reliability: it is 100 times more likely to return a conventional solar panel than a SunPower Performance panel. This translates into total peace of mind for the owner for decades.
Check the details on our SunPower solar panels page.
Are SunPower Performance panels more expensive?
Yes, the initial investment in SunPower Performance panels is higher than that of a conventional panel. However, when analysing the real cost per kWh generated over the entire useful life, SunPower Performance panels usually turn out to be more profitable. These are the factors that compensate for the difference:
- Higher production per m²: they produce more energy on the same roof surface, which translates into more kWh per euro invested.
- Lower annual degradation: they maintain their performance for much longer than the market average.
- 30-year warranty (product, performance and service): the most complete in the sector, with no hidden costs in case of replacement.
- Better behaviour with partial shadows: they take advantage of rooftops with obstacles where other panels would lose a lot of production.
- Extreme durability thanks to the glass-glass construction, resistant to hail, moisture and fire.
In summary: you pay more at the beginning, but you get more energy for more years and with more peace of mind. Discover why we choose this technology on our SunPower Performance panels page.
