50 Watt 12 Volt Polycrystalline Solar Panel
HQST 50 Watt solar panel adopts premium grade A polycrystalline solar cells and offers 19.3% cell efficiency, outperforming the 16% efficiency of other polycrystalline panels on average. The integrated bypass diodes and anti-reflective transparent low iron tempered glass provide high efficiency even in accidental shading or weak-light conditions. With its durable multi-layer construction and waterproof, dust-proof components, the panel offers long service life and withstands extreme outdoor weather for 25+ years.
The panel is suitable for water pumping systems, gate openers, barns, workshops, tool sheds, signaling systems, parties/festival lighting, battery charging in RVs, marine boats, trailers, cottages, cabins, and other off-grid applications.

Yes, you can leave the panel connected when driving the car, but the panels should be mounted parallel to the car roof, without tilt mounting brackets, or dangers may occur. The power output could be affected by local peak sun availability.
Yes, a 12V battery will surely work with this HQST 50W solar panel. Yet solar panels can't be connected with the battery directly. To build a complete solar system, you need to connect the solar panel, charge controller, battery, and inverter in sequence. For a 48V battery, you need to connect at least 3 HQST 50W poly solar panels in series, then connect one charge controller that's compatible with the 48V solar system. The controller's output current should not exceed the battery's maximum charge current, and the whole solar system works normally
You can connect them in series or parallel. To wire the solar panels in series or parallel depends on your needs and application.
In series connection, connect the positive terminal on the first panel to the negative terminal on the next, and so on; their output voltages add together, and the output current remains the same. Series connection is optimal in unshaded conditions. If shade covers a single panel of the array, it will reduce the system’s power output.
In parallel connection, connect all of the positive terminals on each panel, then do the same for the negative terminals; their output currents add together, while output voltages stay the same. Parallel connection is the best option for mixed-light conditions or when you want a low voltage system using a lower-cost PWM controller. If shade covers one or two of the panels, the remaining panels in the array will continue working as expected.
Yes, and you need a battery for power storage; then connect your solar panel, charge controller, and the battery to power your pool filter. Calculate how much power you need per day, then buy compatible components to build your own solar system, or you can turn to HQST service team for a convenient solution.
