How do I use this solar panel?
Our solar panels are designed with pre-drilled holes for easy installation. The solar panel must be connected to a charge controller, which in turn connects to a battery to store the energy. You will need an adapter kit cable to connect the solar panel to the charge controller, and a tray cable to connect the charge controller to a deep-cycle battery. After that, you need to connect an inverter to supply power.
What are the possible applications for this solar panel?
Tempered glass panels are very versatile and can be used in homes, on rooftops, RVs, farms, boats, sheds, or other locations requiring power management. Foldable solar panels are generally used for outdoor settings, such as RVs, boats, and camping scenarios.
Can this solar panel generate power in cloudy conditions?
Yes. This WERCHTAY solar panel is made from high-quality materials and can still function in cloudy conditions. However, please note that its power conversion rate will be lower compared to sunny conditions.
What other equipment do I need to power a load with the solar panel?
You will need a charge controller, a battery, and an inverter to connect and complete the solar panel's power generation system.
Can the solar panel withstand strong winds and snow loads?
Our solar panels use corrosion-resistant aluminum frames, ensuring they operate under various weather conditions. They can withstand winds up to 2400Pa and snow loads up to 5400Pa.
Why is my solar panel's output low?
The performance of solar panels can be affected by various factors. Common environmental conditions, such as indirect sunlight, higher temperatures, cloudy skies, and dust or dirt accumulation on the glass, can all lead to reduced power output.
How should I connect the solar panels in the circuit (series or parallel)?
Solar panels can be connected in series or parallel to meet your circuit size and power requirements. Connecting panels in series will add their working voltage output together while keeping the current output the same as a single panel. Connecting panels in parallel will add the current output of each panel while keeping the voltage output the same as a single panel. To achieve the best power output and system rating, you may use a combination of series and parallel connections.
How many solar panels do I need?
The best way to determine how many solar panels you need is to understand and define the power load required by your system. Power is measured in watts, and capacity is usually measured in watt-hours (watts output multiplied by the required operating hours, then multiplied by a safety factor of 1.5-2). Therefore, it is wise to first determine the size of the battery bank based on the minimum required capacity, and then decide how many solar panels or how much power input is needed.
What is the difference between off-grid and grid-tied systems, and how are they used differently?
An off-grid system, also known as a standalone solar power system, does not rely on an external power grid and forms a self-sufficient power supply system. A grid-tied system, or grid-connected photovoltaic system, is connected to the external power grid and works together with it to supply power.
How do I complete an off-grid solar power system?
The solar panels must be connected to a charge controller to regulate the current and to a battery to store the energy. You will need an adapter kit cable to connect the solar panels to the charge controller and a tray cable to connect the charge controller to a deep-cycle battery.
How many kilowatt-hours does the solar panel generate per day?
Under ideal conditions, i.e., ample sunlight and no energy losses, watt-hours = power per panel * hours of sunlight per day. The actual power generation will be affected by various factors such as weather conditions and light intensity. For example, a 100W solar panel exposed to direct sunlight for 5 hours a day can provide an average of 400-500 watt-hours of electricity (depending on sunlight availability).
