I purchased two four pack on Amazon and at seventy seven cents per watt, you just can't go wrong. These panels have performed as well as my top of the line panels and I expect that HQST will be in business for a long time if they consistently produce quality performers like these. ### ⭐⭐⭐⭐⭐ Compact *by C***R on April 23, 2021* These 100 Watt panels are significantly smaller that others I have ordered from other suppliers. They are not set up yet, but the one question I had about the controller was answered quickly and clearly. I think this is my new supplier for my PV solar field. ### ⭐⭐⭐⭐ preforms the same as more expensive ones *by A***R on December 4, 2020* I ordered these as part of a small off grid system for a shed conversion. I've been impressed with the out put even as we've entered the winter months and have less light. --- ## 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.pt/products/180727454-hqst-400-watt-12-volt-monocrystalline-solar-panel-with-solar](https://www.desertcart.pt/products/180727454-hqst-400-watt-12-volt-monocrystalline-solar-panel-with-solar) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-28*
