Product Description
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. Features: 21.5% EFFICIENCYSunPower X21 panels are the highest efficiency panels on the market today, providing more power in the same amount of space.MAXIMUM SYSTEM OUTPUTComprehensive inverter compatibility ensures that customers can pair the highest efficiency panels with the highest-efficiency inverters, maximizing system output.REDUCED INSTALLATION COSTMore power per panel means fewer panels per install. This saves both time and money.RELIABLE AND ROBUST DESIGNSunPower’s unique Maxeon TM cell technology and advanced module design ensure industry-leading reliability. SunPower X21-345W 345 Watt Solar Panel Module power output and efficiency The graph below shows the typical power produced (in Watts) for the SunPower X21-345W 345 Watt Solar Panel Module at maximum available sunlight (irradiance). The SunPower X21-345W 345 Watt Solar Panel Module has a maximum output of 345 watts. The graph below also shows the efficiency of SunPower X21-345W 345 Watt Solar Panel Module.
