Solar Module Introduction

Solar Module is the core part of solar PV power systems, also is the highest value part of it. The function of Solar Module is to convert the sun's radiation to electrical energy, or transfer it to battery and store in it, or to drive the load running.
The Product has been widely used in space and ground, it mainly used for power generation systems, charging systems, road lighting and traffic signs areas. It could offer a wide range of power and voltage, and with high conversion efficiency, and long service life.

Solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells. These early solar modules were first used in space in 1958.

Electrical connections are made in series to achieve a desired output voltage and/or in parallel to provide a desired current capability. The conducting wires that take the current off the modules may contain silver, copper or other non-magnetic conductive transition metals. The cells must be connected electrically to one another and to the rest of the system. Externally, popular terrestrial usage photovoltaic modules use MC3 (older) or MC4 connectors to facilitate easy weatherproof connections to the rest of the system.

FAQ:

（1）What price for each watt?

It depends on the quantity, delivery date and payment terms.

（2）What is your size for each module? Can you tell me the Parameter of your module?

We have different series of panels in different output, both c-Si and a-Si. Please take the specification sheet for your reference.

（3）Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?

Actually we are only manufacturer of solar panels, but we could try to source them for you in China if you need. We could provide you an optimal system design to instruct you how to install.

（4）Do you have the CE, TUV, UL Certification?

We’ve already passed all the tests, and any certificate is available.

（5）Have you ever sold your products to companies in my country?

Of course, we have customers in all general PV markets, but I think we should expand our market share along with the market growth.

（6）When did your company set up? You are a new company, how can I believe your quality?

We entered into Solar PV industry in 2005, now we have several plants in manufacturing of a-Si and c-Si panels, and our capacity is 220MW per year. Till now we have already passed all the tests by authorized laboratories, e.g. TUV, VDE, UL.

（7）Can you help us install the module if we cooperate with you?

We haven’t entered into installation sector, but we have the plan in near future.

（8) How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

(9) Can you do OEM for us?

Yes, we can.

（10）Can we visit your factory?

Surely, I will arrange the trip basing on your business schedule.

Q:Can solar panels be installed in rural areas?: Yes, solar panels can be installed in rural areas. In fact, rural areas are often ideal for solar panel installations due to the availability of open spaces and ample sunlight. Installing solar panels in rural areas can provide clean and renewable energy to these communities, reducing their dependence on traditional energy sources and improving energy access.

Q:Can solar panels be used in areas with high levels of saltwater exposure?: Yes, solar panels can be used in areas with high levels of saltwater exposure. However, it is important to take certain precautions to prevent corrosion and maximize their performance. This can be achieved by using materials that are resistant to saltwater corrosion, such as stainless steel or aluminum frames, and encapsulating the solar cells with durable and protective coatings. Regular maintenance and cleaning can also help ensure the longevity and efficiency of solar panels in such environments.

Q:Can solar panels be used for off-grid living?: Yes, solar panels can be used for off-grid living. They provide a reliable and sustainable source of electricity by converting sunlight into usable energy. This makes them ideal for powering homes, cabins, or even recreational vehicles in remote areas where access to the utility grid is limited or unavailable. Solar panels enable off-grid living by storing excess energy in batteries, allowing for electricity usage during nighttime or cloudy days.

Q:Most solar panels (the flat ones that go onto roofs of houses) reject electricity produced by the panels if they are too low in voltage. For example, on a cloudy day, although the panels may still get some sunlight to produce some electricity, it is rejected because its too low in voltage. So, does anyone have any ideas?: apart from, the way image voltaic panels are under pressure jointly can impact the voltage output. If the panels are under pressure with the output of one connecting to the enter of the subsequent, or in sequence, the voltages of the panels upload up. case in point, in case you have 4 2 Volt panels under pressure in sequence, the finished voltage of the array could be 40 8 Volts. If the panels are under pressure so as that each and one and all their inputs and outputs are linked, or in parallel, those comparable 4 panels could have a entire voltage of 2 V, however the gadget could have 4 circumstances the present (Amps) of one panel.

Q:Can solar panels be damaged by birds or rodents?: Yes, solar panels can be damaged by birds and rodents. Birds may nest, perch, or peck at the panels, causing cracks or scratches on the surface. Rodents, on the other hand, can chew through the wiring or insulation, leading to electrical issues. Regular maintenance and bird deterrents can help minimize the risk of damage.

Q:Do solar panels produce noise?: No, solar panels do not produce noise as they generate electricity without any moving parts.

Q:Can solar panels be installed on a shopping mall or retail center?: Yes, solar panels can be installed on a shopping mall or retail center. Many commercial buildings, including shopping malls and retail centers, have ample roof space that can be utilized for solar panel installations. Installing solar panels on these buildings can help offset energy costs, reduce carbon emissions, and provide a renewable energy source. Additionally, it can also serve as a visible demonstration of the business's commitment to sustainability and environmental responsibility.

Q:Are solar panels safe?: Yes, solar panels are safe. They are designed and installed to meet strict safety standards. They do not produce any emissions, and the risks associated with solar panels are extremely low. However, it is important to ensure proper installation and maintenance to maximize safety.

Q:I want to replace my electricity with solar and wind. I live just right outside the city, the roof about 000 square feet. How many windmills/solar panels would it take to get me off the power grid?: If you are in the desert and near the equator you will need fewer panels than if you live in a rain forest or Alaska. If you live in a wind tunnel with consistent strong wind, you will have better results than if you live where there often is a lull in the wind and changes of direction of the wind. If you already pump your water by hand, generate your own electricity by cycling using your legs, and go to bed whenever it gets dark out, you might make it. But if you tend to cook and launder on the grid, run a refrigerator, perhaps heat your house or air condition it, own various gadgets you plug into outlets to use, like lamps, puters, toaster, shaver, blender, dishwasher etc, you may not be able to get off the grid.

Q:Can solar panels generate electricity during a blackout?: No, solar panels cannot generate electricity during a blackout unless they are connected to a battery storage system.
