N-Type Bifacial 2PCS 590W Monocrystalline Solar Panel

To build a complete off-grid solar system, you need a bifacial solar panel, a charge controller to regulate power flow, and a battery to store energy. Additionally, you'll need adapter kit cables to connect the solar panels and charge controller, as well as tray cables to link the charge controller to a deep-cycle battery.

An on-grid solar system is connected to the utility grid, allowing you to draw power from the grid and send excess energy back. In contrast, an off-grid solar system is completely independent, storing generated power in batteries for later use. Off-grid systems ensure uninterrupted power and are not affected by grid outages.

A bifacial solar panel may generate less power due to indirect sunlight, excessive heat, cloudy weather, or dirt buildup on the glass surface. These factors reduce energy absorption and overall efficiency.

Solar panels can be wired in series or parallel, depending on your system voltage and current requirements. Series wiring raises system voltage, ideal for high-voltage setups, while parallel wiring boosts current for battery-based systems. In contrast, a parallel connection increases the system’s current while maintaining the same voltage, making it better suited for battery-based systems that require higher amperage. To achieve the best power output and system efficiency, a combination of series and parallel connections may be used based on your solar energy storage and inverter requirements.

To determine the number of bifacial solar panels required for your setup, start by calculating your daily energy consumption in watt-hours (Wh). Divide this by the average sunlight hours per day in your location to estimate the necessary solar capacity. To account for efficiency losses and ensure sufficient power generation, it is recommended to apply a safety factor of 1.5 to 2 times the estimated requirement. Additionally, sizing your battery bank first allows for more accurate panel selection, ensuring your off-grid solar system operates efficiently and meets your energy needs.

• Captures sunlight from both sides • More efficient and powerful than monofacial panels • Performs better in overcast weather • Installs in any direction"
