Produces about 0.6 volts in direct sun *by S***E on December 4, 2020* The media could not be loaded. Both sides produce a voltage in sunlight. They are rated at half-volt. I got about 0.3 volts with indoor shop light and about 0.6 volts in direct sunlight--see 10 sec video. They are fragile, I broke one right away. All solar cells are fragile, and the product description makes it clear they are fragile so that's fair. I had some trouble (maybe my own lack of skill) with soldering tabs, so I tried using clear wrapping tape and it made a good connection and much easier. The picture shows tabbing wire taped on to the cell, producing 5 to 6 volts charging a battery using the 5v micro USB charging port. ### ⭐⭐⭐ Mini Solar Cells *by M***E on December 31, 2024* Purchased this set to use for a college project. Good thing you get 100 of them because they are so fragile. They do what the description states, but the item is very brittle. I had to use quite a few to finish all my connections because of this issue. I would look for something else the next time I need to build a solar project. ### ⭐ How these solar cells Rate 4.5...? *by S***L on June 23, 2023* Cells were very brittle and shattered while soldering.1/2 dozen tries... ManagedWiring,1 cell 📱 bright light0.000 output. 3 of them failed.I am s professional with strong electronics background. Seashells are much much too thin for building a panel. So what did I miss and trying to solder...? ## Frequently Bought Together - SUNYIMA 100pcs Mini Solar Cells 0.5V 0.4W Micro Thin Polycrystalline Silicon Solar Panels DIY 52 x 52mm/2x2inch - Vikocell Solar Panel Solder Kit 20M Tabbing Wire with 2M Busbar Wire and 1 Pcs Flux Pen for DIY Solar Cells Soldering - SUNYIMA 10pcs Mini Monocrystalline Solar Cells Solar System Kit 50mm X 50mm/1.96" X 1.96" 2V 160MA for DIY Charge Solar Panels --- ## 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.gr/products/212364869-sunyima-100pcs-mini-solar-cells-0-5v-0-4w-micro](https://www.desertcart.gr/products/212364869-sunyima-100pcs-mini-solar-cells-0-5v-0-4w-micro) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-27*
