Solarapex 2 Pack 100W Flexible 18V Solar Panel
The Solarapex 2 Pack 100W Flexible 18V Solar Panel set is a portable, lightweight, and adaptable solar charging solution designed for a variety of outdoor and mobile applications. With two flexible 100 W panels, this kit provides up to 200 W of combined power, making it ideal for charging batteries, powering solar generators, or supplementing energy systems in RVs, boats, camping setups, and off‑grid locations.
Unlike rigid panels, these flexible solar panels bend slightly, allowing easy installation on curved surfaces like boat decks, RV roofs, tents, and other non‑flat mounting areas. The 18 V output is perfect for charging 12 V batteries and solar chargers with the appropriate controller.
How It Works
Each solar panel contains photovoltaic cells that convert sunlight into electrical energy:
- Light hits the solar cells and creates electric current.
- DC power (18 V max) flows from the panel’s output cable.
- Panels can be connected in parallel to increase total current (up to ~200 W).
- Power is fed to a solar charge controller to safely charge batteries or power stations.
- The stored energy can then be used to charge devices or run appliances.
This makes the system versatile for off‑grid energy needs.
Key Features
☀ 2 Panels × 100 W Output
A total of 200W solar power generation (if used together), delivering significant energy for outdoor and backup systems.
🌞 18 V Operating Voltage
Designed for ease of use with 12 V battery systems, solar generators, and controllers.
🔄 Flexible & Lightweight Design
Panels can bend up to ~30°, enabling mounting on curved surfaces like RV roofs, boats, and tents.
🔋 Monocrystalline Solar Cells
High‑efficiency cells capture maximum sunlight, even in limited space.
📦 Easy Installation
No heavy frames — the panels can be glued, taped, or strapped to surfaces with minimal effort.
💪 Durable & Weather‑Resistant
Built with protective films and lamination for outdoor use — resistant to moisture, dust, and UV exposure.
📌 Parallel Connectivity
Panels can be connected together (parallel wiring) to increase total power while maintaining safe voltage.
Pros and Cons
| Pros (Advantages) | Cons (Disadvantages) |
|---|---|
| 2 panels for increased power (200W total) | Flexible design slightly less efficient than rigid panels |
| Lightweight and easy to mount | Requires a solar charge controller |
| Works on curved surfaces (boats, RVs) | Must align with sunlight for best output |
| Compatible with 12 V systems | Not suitable for heavy appliances |
| Ideal for portable and mobile setups | Efficiency reduced in shade/cloudy weather |
| Weather‑resistant for outdoor use | Folding and handling require care |
Best Uses
The Solarapex 2 Pack 100W Flexible 18V Solar Panels are ideal for:
- RV and camper solar installations
- Boat and marine solar charging
- Camping and outdoor power needs
- Off‑grid cabins or workshops
- Solar generator charging
- Emergency power backup systems
The flexibility of the panels opens up mounting options that rigid solar panels cannot accommodate.
Installation Tips
✔ Use a Solar Charge Controller — Essential for safe battery charging and preventing overcharge.
✔ Optimal Sun Exposure — Angle the panels toward direct sunlight for maximum output.
✔ Mount Carefully — Flexible panels should be secured flat to the surface for the best performance.
✔ Parallel Wiring — If combining both panels, ensure correct polarity and use suitable connectors.
