Essential Mounting Considerations:

For optimal installation and crucial cooling performance, please be aware that the integrated junction box on the rear of the panel protrudes approximately 0.5cm beyond the main frame. To ensure adequate airflow and prevent potential overheating, we highly recommend maintaining a clearance of 1.0 to 1.5cm between the panel and any flat mounting surface. Adhering to this guideline is vital for maximizing the panel's efficiency and extending its operational lifespan.

Enhancing Your 12V Battery System:

If your primary objective is to charge a 12V battery, the inclusion of a solar charge controller (also commonly referred to as a regulator) becomes an indispensable component of your system. This critical device safeguards your battery against the risks of overcharging and ensures the efficient, regulated transfer of power from your solar panel. Should you not possess such a device, we invite you to explore the diverse range within our shop’s dedicated category for solar charge controllers. All our solar charge controllers are accompanied by comprehensive instruction manuals, complete with detailed wiring diagrams, which simplify the entire installation process.

Seamless Power Expansion:

Already utilizing one of our 20W solar panels or a complete kit featuring a solar controller? You possess the convenient option to effortlessly augment your power capacity, effectively doubling your output to 40W, by connecting this additional panel in parallel. The connection process is intuitive: simply align the positive ("+") terminal of this panel with the positive ("+") terminal of your existing panel, and correspondingly, connect the negative ("-") terminal to the negative ("-") terminal. Subsequently, integrate this combined array into your solar controller. This method presents a straightforward means to significantly bolster your renewable energy capabilities!
