9V 5W Polycrystalline Solar Panel | 330x175mm Aluminum Frame

9V 5W Polycrystalline Solar Panel | 330x175mm Aluminum Frame

Product Overview

The 9V 5W Solar Panel from Pro Tronix is a heavy-duty energy solution for makers who need more than just a small hobby cell. Measuring 330mm x 175mm, its larger footprint allows for better energy harvest even during cloudy days or in partial shade.

Unlike flexible or epoxy-coated cells, this panel is encased in a rugged 17mm anodized aluminum frame with a tempered glass front. This industrial-grade construction protects the polycrystalline cells from impact, dust, and moisture, making it ideal for permanent outdoor installations. The 9V output is specifically optimized to provide enough “headroom” for 5V regulators to maintain a constant output even as the sun’s intensity fluctuates.

Technical Specifications

Key Features

• Rigid Aluminum Frame: Provides easy mounting points and protects the panel from bending or mechanical stress.

• Optimized for 9V Systems: Perfect for directly powering 9V devices or charging 6V lead-acid and 7.4V Li-ion battery packs via a controller.

• Weather Resistance: Built to survive the harsh Egyptian climate, featuring UV-resistant materials and a sealed junction box.

• High Efficiency: Polycrystalline cells offer a great balance between cost and energy conversion rate.

Common Applications

• Smart Agriculture: Powering long-range LoRa sensors and water valves in remote fields.

• Outdoor Security: Keeping battery-operated wireless cameras or motion-activated lights charged.

• Arduino Power Supply: Providing a constant source of renewable energy for “always-on” outdoor weather stations.

• Portable Power Banks: Integrating into a DIY solar briefcase for charging phones or small gadgets in the desert.

💡 Pro Tip: To maximize efficiency, tilt the panel at an angle approximately equal to your latitude (around 30° in Egypt) facing South. For charging 5V USB devices, we recommend using a DC-DC Buck Converter to step the 9V down to a stable 5V.
