ShadowFlux 12V Solar Panel Anti-Shadow 200W / 120W

Shadowflux Anti-Shading technology helps maintain high power output even when the solar module is partially shaded, significantly boosting the total power generated. It also protects the module from damage that shading may cause.

To set up an off-grid solar system, you’ll need a solar panel connected to a charge controller to regulate the current, and a battery to store the power. You’ll also need adapter kit cables to connect the solar panels and charge controller, plus tray cables to link the controller to a deep-cycle battery.

On-grid simply means solar power equipment (array or solar panel) is connected to the electrical grid, while off-grid refers to systems that are not connected to the grid and therefore store the generated power for later use. Off-grid systems are not affected by grid blackouts.

Several factors can cause solar panels to underperform, most commonly environmental conditions like indirect sunlight, high temperatures, cloudy skies, or dirt and debris on the glass surface, all of which reduce output.

Solar panels can be connected in series or in parallel to meet your electrical circuit size and power demand. Connecting solar panels in series will have the effect of adding up their operating voltage output, while system current output will be the same as that for one panel. While, connecting solar panels in parallel will have a different effect; individual panels operating current output will add up to be the system output current, while system output voltage will be the same as the output voltage of one solar panel. To meet the optimum power output and system rating for your power system, you can use both parallel and series connections.

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 Watts, 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 12V/24V in product titles (ex. 150W 12V CIGS Solar panel) does not refer to the actual voltage (Voc or Vmp) of the solar panels, but rather to the voltage of the solar system or energy storage system to which the panel is best suited. The voltage of the solar panel must be higher than the solar system voltage. "
