Frequently Asked Questions
The ALLPOWERS foldable solar panel can charge most batteries (charge controller needed) and power stations.
It is important to ensure that the open circuit voltage of the panel will not exceed the max DC input voltage rating of the power station or charge controller.
The choice between connecting solar panels in series or parallel depends on your specific setup and requirements.
- Series connection: Connecting solar panels in series increases the voltage output while keeping the current the same. This is useful when you need to increase voltage to match the requirements of your charge controller or inverter.
- Parallel connection: Connecting solar panels in parallel increases the current output while keeping the voltage the same. This is beneficial when you want to maximize the current for charging batteries or powering devices directly.
The best way to gauge how many solar panels you need, is to understand and define the power load needed from this system. Power is measured in Watt, and capacity is commonly measured in Watt-hours (multiplying power output in watts by the required number of hours of operation multiplied by a safety factor of 1.5-2). Therefore, it is wise to size your battery bank first based on the minimum required capacity, and accordingly decide how many panels or how much power input is needed.
The cells of the SP037 solar panel are waterproof with an IP67 rating. It can be used outdoors. However, the back of the folding package is made of canvas, which is prone to aging if exposed to the elements for extended periods. Additionally, the connectors are not designed for long-term exposure to sun, wind, and weather. The folding solar panel is more suitable for on-the-go use and should be stored away when not in use. For long-term outdoor applications, we recommend considering flexible or rigid solar panels.
