  • Performs well in weak light for reliable daily charging

DIY Solar Panel for Small Projects

The crystalsolar SW4506N is a compact monocrystalline silicon panel rated at 4.5W with a 6V working voltage and 0.75A working current. It measures 165 by 135 by 3mm and weighs 0.089 kg. The supplier notes a maximum conversion rate of 17 percent and highlights excellent weak light performance for consistent output in varied conditions.

Hobbyists and Off-Grid Experimenters

This panel suits makers building solar powered water pumps, home lighting prototypes or small off-grid demonstration systems where a 6V source is required. Builders who need higher voltage, greater wattage or integrated battery management should look at other solutions because this unit provides only the raw photovoltaic output.

6V Working Voltage Defines Compatibility

The fixed 6V working voltage is the single specification that determines whether the SW4506N matches your circuit. Every downstream component — charge controller, pump, lighting module or microcontroller board — must be designed for a 6V input or the system will not operate correctly.

Questions about this item

Should I pick the 4.5W 6V panel or a different wattage for my DIY lighting project?

Choose the 4.5W 6V model when your load draws around 750mA at 6V; its 17% conversion rate and 165×135mm size suit small home lighting, toys or water pumps.

What does the 4.5W rating deliver once the panel is mounted on my shed roof?

Under full sun the panel produces 6V at up to 0.75A, giving 4.5W; in weak light output drops but the monocrystalline cells still generate usable current for battery charging.

Does the 6V output work straight into a 5V USB charger board?

The panel’s 6V working voltage feeds a 5V regulator or charge controller directly; no extra converter is needed, just add blocking diode and capacitance for stable USB power.
