SunPower X21-345W 345 Watt Solar Panel Module
SunPower X21-345W 345 Watt Solar Panel Module – this is an independent review for SunPower X21-345W 345 Watt Solar Panel Module we have compiled for your reference. Feel free to add your comments or experiences at the bottom of the page.
SunPower solar panels achieve record panel efficiencies of over 21%. SunPower panels convert a greater percentage of sunlight into electricity. This means that over the lifetime of the array, it will generate more electricity and save on electricity bills.
SunPower panels integrate SunPower Maxeon solar cell technology with high efficiency solar cells and a patented, anti-reflective coating to increase sunlight absorption.
This large wattage of 345W means this panel is ideal for domestic roof tops where space is limited as you can still achieve maximum output in small areas.
SunPower X21 panels are the highest efficiency panels on the market today, providing more power in the same amount of space.
MAXIMUM SYSTEM OUTPUT
Comprehensive inverter compatibility ensures that customers can pair the highest efficiency panels with the highest-efficiency inverters, maximizing system output.
REDUCED INSTALLATION COST
More power per panel means fewer panels per install. This saves both time and money.
RELIABLE AND ROBUST DESIGN
SunPower’s unique Maxeon TM cell technology and advanced module design ensure industry-leading reliability.
