What do I need to complete my off-grid solar power system?
Components, controllers that match the components, batteries that meet system requirements, and cables of corresponding specifications are required. If AC power is required, add an inverter to provide AC output.
Why can't my solar panel output in accordance with nameplate power?
The amount of electricity produced by solar panels can be affected for a number of reasons. Such as sunlight, temperature, glass surface dirt and stains.
How should I connect the solar panel to the system (series vs parallel)?
Solar panels can be connected in series or parallel to meet your circuit size and power needs. Connecting the solar panels in series will make their operating voltage outputs superimposed, and the system current output will be the same as one panel. Connecting solar panels in parallel has a different effect; The operating current output of the individual panels will be added.
Can I walk on bendable/border components?
We suggest no. Walking on a solar panel can put too much pressure on a small area, potentially causing cracks and damage to the panel.
How to clean solar panels?
Clean up with alcohol only. Dust and sediment are cleaned with a dry cloth.
Are these Mono-cells or poly-cells?
Mono-component cells are round chamfered and Poly-components are straight chamfered.
Can this panel generate electricity on cloudy days?
Normal power generation, but the generation efficiency will be reduced.
Can these panels be used in grid-connected systems?
All components can be used with off-grid and grid-connected systems (except portable rechargeable PV products).
Are there pre-drilled holes in the back of these panels?
There are mounting holes, leakage holes, and ground holes on the frame of each component , but the modules are sold without matching brackets, you need to buy "Z" brackets from the official website to install, and you need to pay attention to whether the brackets match the mounting holes of the modules. Does the solar panel contain all the wiring?
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.
Can different brands of panels be mixed?
It is not recommended and must be used in accordance with the instructions.
How many solar panels do I need?
The best way to measure how many solar panels you need is to understand and define the electrical load required for the system. Power is measured in watts and capacity is usually measured in watt-hours (multiply the watt output by the number of working hours required, and then multiply by a safety factor of 1.5-2).
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 (not exceeding).
What kind of extension cord should I buy on this panel to make my RV more flexible?
The extension cable between the component and the component is kept with the same specifications as the component connector wiring. At the same time, be careful not to extend the cable more than 2M, because the longer the extension cable, the higher the line loss, and the temperature of the cable will rise and there is a safety hazard. For the extension cable connected to the controller after series/parallel connection of the components, please confirm the specification of the extension cable according to the current of the components after series and parallel connection.
How many kilowatt hours can this solar panel produce in a day?
In the case of STC, the power generation is the product of standard power and time (W*H).
If the original mark/sticker no longer exists, how can the customer visually tell which cables are positive/negative?
Positive and negative labels are marked on the connector heads of the component connectors.
Why do solar panels have higher open circuit voltages than other system components?
Consumers are worried about damaging their controllers. The open voltage is a standard value, which is determined by the physical characteristics of photovoltaic modules; After the controller is actually connected, there will be a normal voltage drop, so the controller will not be damaged.
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. T
What is the difference between flexible and framed components?
Flexible components: easy to install, applicable to more scenes, lightweight, easy to move and place does not occupy space, the disadvantage is that the mechanical properties are slightly weak load resistance is not strong. Bezel assembly: advantages of strong load resistance mechanical properties. Disadvantages: installation on the roof of the car requires drilling, installation trouble. Electrical performance.
