FellDen Micro Solar Panels Kit 5PCS 5V 200mA — Thin Epoxy-Encapsulated DIY Panels

FellDen's 5PCS Micro Solar Panels Kit delivers five compact 5V/200mA polycrystalline solar cells with leads for DIY low-power projects and small off-grid setups.

This kit groups five slim, weather-resistant photovoltaic panels designed for hobbyists, educators, and makers who want an easy-to-integrate power source for low-current DC devices. Each panel measures 110mm x 60mm and is only 2.5mm thick, making them simple to mount, combine, or embed into models, small solar chargers, or demonstration rigs. The panels are encapsulated in epoxy resin to improve durability, resist light precipitation and particulate wear, and extend usable life compared with bare cells.

How will these panels perform in a small solar project?

Each panel produces approximately 5 volts at up to 200 milliamps under ideal sunlight, which makes them suitable for charging small batteries, powering LED lighting, or running low-draw DC pumps and sensors. Connecting panels in series raises voltage; wiring them in parallel increases current. Performance depends on sun exposure, angle, and shading, so placement matters for real-world output.

• Output per panel: ~5 V, 200 mA (peak sunlight)
• Combine in series for higher voltage or parallel for higher current
• Thin profile (2.5 mm) fits into compact builds and enclosures
• Epoxy encapsulation improves resistance to weather and handling

What mounting and wiring options work best with these cells?

The kit includes wires attached to each panel so you can quickly test or connect panels without soldering, though adding solder or MC4/quick-connects can give more durable joins. Panels can be fixed with silicone adhesive, double-sided tape, small brackets, or within 3D-printed mounts. Ensure good ventilation and avoid permanent occlusion of the active surface to maintain output.

• Pre-attached wires for fast prototyping and testing
• Mount with adhesive, tape, brackets, or custom mounts
• Avoid full shading and allow airflow to limit heat buildup
• Seal connections for outdoor installations to prevent corrosion

Which low-power devices and projects are these panels suited for?

These micro panels excel with hobby electronics and educational demonstrations—think LED strips, small water pumps, microcontrollers on low duty cycles, and battery top-ups for NiMH or Li-ion packs when paired with proper charge management. They are not intended to run high-consumption appliances but are excellent for proof-of-concept systems and solar learning kits.

• LED lighting arrays or indicator lights
• Small DC water pumps and solar fountains
• Sensor stations and small microcontroller setups
• School projects, prototypes, and maker builds

Who is this for? The FellDen Micro Solar Panels Kit is built for DIY enthusiasts, educators leading hands-on solar lessons, tinkerers building compact solar chargers, and model-makers adding realistic powered features. If you need lightweight, easy-to-handle photovoltaic cells to experiment with series/parallel configurations or to add renewable power to small devices, this five-piece set offers a cost-effective, durable starting point. For larger or continuous-load applications, plan to combine multiple kits and include proper charge controllers and storage batteries to manage energy safely and reliably.
