It seems you're providing specifications for a solar-powered lamp system, likely for a project or product development. Here's a breakdown of what you're describing:
15W Poly Solar Panel:
This solar panel is designed to convert sunlight into electrical energy at 15 watts of power. Being polycrystalline (poly) means it is made from multiple silicon crystals, which is usually cost-effective but slightly less efficient than monocrystalline panels.
3.7V 5000mAh Lithium Battery:
The battery is a lithium-ion type, with a capacity of 5000mAh (milliampere-hour). This would store the electrical energy generated by the solar panel, with a voltage of 3.7V. It indicates the battery could supply 5000mAh of power over an hour (or less if more devices are connected).
This battery could be used to power devices that need low to medium power, like small lamps or electronics.
Lamp Size: 13013055mm (4 pcs):
Each lamp is 130mm by 130mm in width and length, with a depth of 55mm.
With "4 pcs," it suggests there are four separate lamp units.
Possible Use Case:
This setup is likely for outdoor or off-grid lighting solutions, such as garden lamps, street lamps, or emergency lights. The solar panel would recharge the battery during the day, and the stored energy would be used to power the lamps at night.
Would you like help with anything specific, such as calculations for energy usage, possible configurations, or something else regarding your setup?
