They are Big & Heavy! Had a problem with the 3rd party deliverer, the driver showed up in a truck with a lift gate that wasn't big enough for this X-Large pallet to fit completely on. If it hadn't been for a neighbor helping with his front-end loader/forks, we would've never gotten it offloaded. Haven't tested them yet, but look to be of good quality. Just wish the cables were longer. Review: Excellent solar panels - Best bi-facial Solar Panels I’ve bought to date high-quality high production shipped on time.

Excellent product. ### ⭐⭐⭐⭐⭐ Solar panel installed *by R***N on March 22, 2026* The first set of panels arrived damaged during shipping, so I refused the order without any issues. I reordered them, and the second shipment came in perfect condition. The output has been excellent, especially given my limited space. These panels complete my system, and I don’t expect to ever need to add anything else. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/807937044-sungoldpower-ul61730-n-type-4pcs-450w-bifacial-solar-panels-16bb](https://www.desertcart.jp/products/807937044-sungoldpower-ul61730-n-type-4pcs-450w-bifacial-solar-panels-16bb) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-13*
