Understanding Partial Shading Impact
The Problem with Conventional Solar Panels
in the real world solar panels regularly undergo partial shading sticks leaves dust even bird droppings and what happens when a solar panel is partially shaded that depends on which solar panel for some a shaded cell can lead to significant power loss why because a shaded solar cell can't generate power and it can't properly pass the power generated by its unshaded neighbor cells instead it dissipates that power resulting in additional power loss for the entire panel
SunPower Maxeon Cell Technology
for this conventional panel partial shading on just one cell shuts down a third of the entire panel but sun power is designed differently sunpow patented maxion cell technology is optimized with built-in protection so that if and when a leaf or anything else Shades a cell only the Shaded cell Powers down resulting in far less power loss
Initial Shading Experiment Results
let's look at the power output of two panels under shading in this experiment sunow panels are more efficient than conventional panels to begin with so they produce more power now let's see what happens when we shade a small portion of the panel sun power is operating at 89% while the conventional panel is down to 66%
Long-Term Performance and Reliability
Protection Against Continuous Shading
and if shading continues over time a conventional front contact panel will fail resulting in 100% power loss but sunpow maxion technology has built in protection for each cell ensuring consistent power production even if shading continues
Designed for Real-World Durability
bottom line sun power panels are designed for the real world and sunpow exhaustive testing ensures that their systems perform consistently hassle-free for well over 25 years sun power designed for life in the real world

Frequently Asked Questions
Q1: What happens to conventional solar panels when partially shaded?
A1: When a conventional solar cell is partially shaded, it can't generate power and it can't properly pass the power generated by its unshaded neighbor cells. Instead, it dissipates that power, resulting in additional power loss for the entire panel. For some, a shaded cell can lead to significant power loss, sometimes shutting down a third of the entire panel.
Q2: How does SunPower Maxeon cell technology address partial shading?
A2: SunPower's patented Maxeon cell technology is optimized with built-in protection so that if and when a leaf or anything else shades a cell, only the shaded cell powers down. This results in far less power loss and ensures consistent power production even if shading continues.
Q3: What is the expected lifespan and reliability of SunPower solar panels?
A3: SunPower solar panels are designed for the real world. SunPower's exhaustive testing ensures that their systems perform consistently and hassle-free for well over 25 years.
