Frequently Asked Questions
1. Do these panels have brackets attached to the roof?
The component itself is equipped with a junction box connector output voltage. If you need to access the off-grid system, you need to purchase additional appropriate wiring.
2. Can this solar panel accommodate 12V/24V/36V/48V batteries?
It can be used, but must be connected to a controller. When selecting the controller, it is necessary to adapt the maximum component input power that the controller can access (without exceeding it).
3. How many kilowatt hours can this solar panel produce in a day?
In the case of STC (Standard Test Conditions), the power generation is the product of standard power and sunlight exposure time (W * H).
4. What is the difference between high power modules and low power modules?
The biggest difference is that the efficiency of the cells used is not the same, which will result in different power generation efficiency of the PV modules. At the same time, due to the different efficiency of the cells used, their open voltage will not be the same. In addition, at the installation end, the high power module needs less quantity to meet the customer's demand compared to the low power module, which is also convenient for the wiring and installation at the installation end.
5. What are the operating parameters and conditions for these solar panels?
The panels operate reliably at temperatures ranging from -40°C to 85°C, with a normal operating cell temperature of 45±2°C. They can withstand up to 5400Pa static loading on the front side and 2400Pa static loading on the back side, with a safety level of Class II.
6. What materials are used for the frame and glass panels?
The panels are engineered with a heavy-duty anodized aluminum alloy frame and a 3.2mm coated tempered single glass layer to maximize durability and weather resistance while ensuring high light transmission.
