SunPower solar panels – are you ready for a giant leap in solar technology? SunPower Corporation, part of the Maxeon Solar Technologies Group, manufactures the highest wattage panels available on the market, including the world’s first 400W solar panel for the home: the SunPower Maxeon 3 400W. These premium, highly efficient SunPower solar panels will help you save more in energy bills compared to conventional solar panels, harnessing clean, free energy for your home or business.
SunPower solar panels, Unbeatable warranties
SunPower panels come with three market-leading warranties for complete peace of mind:
- Power: The power output of all solar panels gradually decreases over time. Most panel manufacturers guarantee no more than 20% degradation over 25 years. SunPower Maxeon 3 panels, on the other hand, offer a remarkable 8% maximum degradation guarantee over the same 25-year period.
- Product: The SunPower Corporation also employs next-level manufacturing techniques in order to deliver expertly finished panels. As standard, Maxeon panels are covered for defects relating to materials and workmanship for 25 years.
- Service: Finally, in the unlikely event of a SunPower solar panel failing, the defective panel would be repaired or replaced free of charge for the full 25-year period. If no suitable repair or replacement were available, you would be reimbursed for the cost of the panel.

SunPower Maxeon 3 solar panels
SunPower Maxeon is the most advanced type of solar panel on the market.
The SunPower Corporation has been developing the most efficient solar panels in the world for over 10 years.
After manufacturing over 3.5 billion solar cells and 30 million panels, its top-of-the-range Maxeon 3 panels (product code: SPR-MAX3-400) offer unrivalled performance and longevity.
The unique SunPower Maxeon solar cells eliminate 86% of the reasons that normal cells could fail, and deliver up to 35% more energy from the same roof space over the first 25 years.


Elimination of grid lines
Maxeon solar cells incorporate ‘back-contact conductivity’, eliminating ugly metal grid lines on the front of the panels, and helping them to absorb more light.
Solid metal backing
Metal reinforcement adds considerable strength to each solar cell, enabling them to resist corrosion and, at the same time, making the whole panel much more durable.
Robust connectors
SunPower solar panels have built-in strain relief and triple-redundant connectors, thereby controlling the expansion and contraction caused by daily temperature swings.

More Power = more Savings
Example: 29% more power from the same roof space
15 conventional 310W panels produces a 4.65 kWp solar array. However, using SunPower 400W panels, you create a 6 kWp solar PV system. That represents 29% more power form the same number of panels.
SunPower solar panels – Unmatched reliability
SunPower panels may cost more, but panel quality is guaranteed. In real-world testing of 800,000 panels at 264 locations over 8 years, SunPower Maxeon panels demonstrated the lowest cell degradation rates in the entire industry, with almost 4x stronger reliability than conventional panels.
Moreover, all panels are backed up by the industry-leading SunPower Corporation ‘Complete Confidence Panel Warranty’.

To complement your SunPower solar PV system, we can design a battery storage solution
Most solar panels systems generate more electricity than you can use at any given moment. The upshot? A considerable amount of precious solar energy is lost to the grid.
The way around this problem is to install battery storage, such as the Tesla Powerwall. Advantages include:
- Capture surplus solar energy
- Provide electricity in a power-cut
- Store cheap, off-peak electricity
- Charge your electric car from the sun even when the sun isn’t shining
