When you're considering a solar installation for your home, it's crucial to make sure the solution has a superior solar panel.


  • 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.

Have you ever heard that you don't start a house from the roof? Well, for engineers, when we talk about solar energy and energy self-sufficiency, it's just 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

alt.faqs-question

What makes SunPower Performance panels superior to other panels?

alt.faqs-arrow


SunPower Performance solar panels stand out due to their advanced technology and robust construction. Their key features include:

  • N-Type TOPCon cell technology: They use phosphorus-doped silicon with a special layer that reduces energy losses.
  • Shingled cell design: The cells overlap to maximize surface area, and in case of shading, the panel continues to produce energy in other areas.
  • Flexible connections: These prevent the cells from breaking or developing micro-cracks, a common issue in other panels caused by temperature changes.
  • Glass-on-glass construction: This structure makes them extremely resistant to hail impact, moisture, and fire. Additionally, it allows for energy generation on both sides (bifacial).
alt.faqs-question

How do shadows affect energy production with SunPower Performance panels?

alt.faqs-arrow

The shingled design of SunPower Performance solar panels significantly reduces the impact of shadows. Unlike conventional panels, which work like a series circuit and can stop producing almost completely if one part is shaded, the shingled design creates multiple parallel circuits. This means that if a shadow affects a small area, the rest of the panel continues to generate energy at almost full capacity.

alt.faqs-question

What is the warranty for SunPower Performance panels?

alt.faqs-arrow

SunPower Performance panels come with a 30-year triple warranty, which covers:

  • Product: A warranty against manufacturing defects.
  • Power: A generation warranty, ensuring the panels will maintain 87% of their original power after 30 years.
  • Service: The warranty includes full panel replacement, covering shipping costs and installer labor.
alt.faqs-question

Are SunPower Performance panels more expensive?

alt.faqs-arrow

While the initial cost may be slightly higher, their technology and durability make them a very profitable long-term investment. Their ability to produce more energy for more years, minimal degradation, and extensive warranties result in substantial savings and greater peace of mind for decades.

alt.faqs-question

How resistant are these panels to weather conditions?

alt.faqs-arrow

Thanks to their glass-on-glass construction and POE encapsulant, SunPower Performance panels have extreme durability. They are certified to withstand hail impacts of up to 45 mm, exceeding usual standards. They are also highly resistant to dust, sand, and salt spray, making them ideal for coastal areas.
