SunPower 345w solar panels for grid tie, off grid, boat, shed, trailer, van, RV, DIY, or pro solar installation

Price: $175 each Discounts available for purchases of 11 or more! This is the SunPower SPR-X21-345 solar panel, the *highest* efficiency Tier 1 solar panel manufactured today, comparable only to the LG Neon R which sells new for more than twice the price. This is not the lower wattage Maxeon 2 327 watt panel, nor the very older Maxeon 1 305w panel which was manufactured 10 years ago that needs to be positively grounded. This is the latest version SunPower panel, and the performance is exceptional, especially if you have a small roof, or want to minimize the number of panels on your roof, and save on wiring, racking, and labor costs. These panels are used, with normal signs of wear from installation and removal on the frame and glass. There is no impact to the mounting, functionality, or electrical output. The panels are in very good cosmetic condition, and in excellent electrical condition: I tested the voltage output in full sun in the late morning, and voltages were in the 66.5 to 67.5v range. This is *excellent* performance, as the ideal Voc under STC (standard test conditions) is 68.2v, and the nominal voltage under NOCT (normal operating cell test) conditions is 64.9v. Based on the very low degradation, these panels were probably manufactured 1 to 2 years ago. The panels have the manufacturer label, with UL and fire rating, so they can be used in a normal grid tie aplication. Or ground mount, off-grid, boat, shed, trailer, food truck, van, or RV application. No serial number label, and no warranty from Sunpower nor me is included or implied. It’s not needed, as SunPower's failure rate is 27 in 1 million; ie: only one panel in 37,000 is defective. I have inspected every panel; no broken glass, bent frames, brown cells or snail trails on cells. No nicks or cuts on the junction box cables or back sheet. The junction boxes have standard MC4 connectors, and I’m happy to test panels with you before purchase. Dimensions: 61.4" tall, 41.2" wide, 1.81" deep 41lbs
