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: Do solar panels work in cloudy weather?: Yes, solar panels do work in cloudy weather. While they may not produce as much electricity as they would on a sunny day, they can still generate power from diffused sunlight. Cloudy conditions can reduce the efficiency of solar panels, but they are still capable of converting light into electricity, making them a viable option for renewable energy even in less sunny areas.

Q: Do solar panels require batteries?: No, solar panels do not require batteries. They generate electricity directly from sunlight and can be connected to the electrical grid to supply power or utilize net metering to offset energy consumption. However, batteries can be used to store excess energy for later use when solar generation is low or during power outages.

Q: Dont/Cant work alone?when you buya asolar panel you mUST GET bATTERIES, voltage regulators and many else stuff?cant they just work directly? or can i use normal batteres like Car batteries?The one who Really knows 0 pts. thanks: It is a system, you can get a small scale panel that can do things like charge cel phones and ipods. The type of system I have installed on my home needs a converter that turns the dc current that is produced by the panels into ac current to run in my home. I don't have a battery system because I'm not off the grid. When I'm generating more electricity than I am using I sell it back to my utility and at night when I'm not gernerating any electricity I buy it back again. Basically my meter runs backwards durning the day and frontwards during the night.

Q: Can solar panels be used to power a school?: Yes, solar panels can be used to power a school. By installing solar panels on the school's roof or surrounding areas, sunlight can be converted into electricity, providing a clean and renewable energy source. This can help reduce the school's reliance on fossil fuels, lower energy costs, and contribute to a more sustainable and environmentally friendly learning environment.

Q: Can solar panels be installed on warehouses?: Yes, solar panels can be installed on warehouses. In fact, warehouses are ideal locations for solar panel installations due to their large roof spaces and minimal shade obstruction, allowing for maximum exposure to sunlight and optimal energy generation.

Q: Does anyone own any and would you recommend them? right now i only own solar stake lights and i use them during the summer in my yard. But during the winter i take them out because they don't charge well. I live in toronto canada where it snows a lot during the winter, would it even be worth it to buy solar panels? Would they get covered with snow if the were mounted on my roof and get ruined? I plan on buying some when i purchase my own home.Any info would be appreciated:): Toronto would not be higth on my list of solar panel worthy locales. They are a bit pricey and are only cost effective in climates and locations with lots of direct sunlight. But if you could safely say you get direct light on your rood nearly every day, they could work. Wind turbines are getting better... especially omnidirectional dome type turbines. But again they are a bit costly, and work best if you believe you get direct wind for at least half the day. If your roof is reasonably flat and structurally sound, a solar hot water generator can be quite cost effective. Essentially it is a panel of corrugated metal under two thin transparencies of plastic. Water is pumped up to it and as it runs along the corrugation, the trapped heat under the plastic heats it up nicely. They are cheap to buy and easy to build and install, and will completely remove the need for a dedicated hot water heating system. Once again, it really depends on the precise location and construction of your house. Do a search for solar heat in your area. If it is cost effective, someone will be offering...

Q: Can solar panels work during cloudy or rainy days?: Solar panels can still generate some electricity during cloudy or rainy days, although their efficiency may be reduced. The panels can still absorb and convert diffuse sunlight into electricity, albeit at a lower rate compared to sunny days.

Q: Can solar panels be used to power a water pump?: Yes, solar panels can be used to power a water pump. Solar panels convert sunlight into electricity, which can be used to power various devices and appliances, including water pumps. This allows for a sustainable and environmentally friendly way to pump water without relying on traditional energy sources.

Q: How are solar panels made?: Solar panels are made using a complex manufacturing process that involves several key steps. First, high-quality silicon ingots are sliced into ultra-thin wafers. These wafers are then treated with various chemicals to enhance their electrical properties. Next, metal contacts are added to the front and back of the wafers, allowing for the flow of electricity. The wafers are then assembled into a module, encapsulated in a protective layer, and sealed with a glass cover. Finally, the completed solar panels undergo rigorous testing to ensure their efficiency and durability before being ready for installation.
