Solar Panel and Charge Controller
This solar system utilizes a 50-watt solar panel, capable of delivering a charging current of 2-3 amperes. This is a significant aspect of the system's power generation capacity.
Paired with the solar panel is a solar charge controller, purchased separately for cost-effectiveness. This controller manages the charging process, ensuring optimal battery life.
The controller also features two USB ports, allowing for convenient charging of mobile devices directly from the solar system.
Mini Power Inverter
The system incorporates a 200-watt mini power inverter, converting 12V DC power from the battery to 220V AC for household appliances.
This inverter is compact and includes an output socket and a 5V USB port. A power on/off button and an LED indicator light are also present.
The inverter features a cooling fan to manage heat dissipation during operation, extending its lifespan. It's designed for car use, but this review demonstrates its applicability to small home appliances.
Battery and Connections
A 25Ah lead-acid battery provides energy storage for the system. Its voltage level and charge status are displayed on the charge controller.
Connecting the battery, solar panel, and inverter to the charge controller is straightforward; clear plus and minus markings facilitate easy installation.
The system's simplicity means the installation process is relatively easy, suitable for average DIY enthusiasts.
Load Testing and Performance
Load testing was conducted using a power meter, demonstrating the system's capacity to handle various appliances.
The system successfully powered a 40W TV, a 100W bright light, and a high-wattage Farada fan simultaneously, reaching a combined load of approximately 150W.
While the system performs well under test conditions, the small battery capacity limits extended use of high-power appliances like the fan.
Pricing and Conclusion
The estimated cost of the entire system, including inverter (₹1500-1600), charge controller (₹400-500), battery (₹1500-2000 offline, ₹3500 online), and solar panel (₹1700-1800 offline, ₹2000-2500 online) varies widely based on purchasing method.
This system is best suited for low-power applications like lighting and mobile charging due to its small battery capacity. A DC fan could be a better option than an AC fan with this setup.
For higher power demands, consider upgrading to a larger battery and solar panel. Overall, this inexpensive kit offers a convenient, entry-level solar solution for basic power needs.
