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.

Surely, I will arrange the trip basing on your business schedule.
- Q: Can solar panels be installed in a desert environment?
- Yes, solar panels can be installed in a desert environment. In fact, deserts are often ideal for solar panel installations due to their high levels of sunlight and minimal cloud cover. The dry climate also helps to minimize dust buildup on the panels, making maintenance easier.
- Q: Hello, I have been trying to go green, I Have purchase somesolar panel they are about 45watts I been putting it against my window and getting ok power out of it enough for my lights and a couple of low watts gadget (cellphone, 2v light, portable dvd) for couple of hours.But its seem to drain the 2v faster then I can charge Am I getting the most power out of my panel?Or should I place it on the roof? I'm in Texas and it gets hot and sunny the sun beam my room windows pretty good during 4pm-6pm.
- outside is going to be much better. You can't tell but glass is actully opaque to many ranges of 'light'. If you look at advertising for windows you may see claims to reduce sun fading of your carpet/ furniture. That is because the glass blocks UV. Solar panels get some of their energy from UV light. Also some windows are engineered to block IR to help insulate better when the house is cooler than the outside. Again, solar panels get some of their energy from light in the infrared range. And finally if you're charging batteries the 'off angle time' is still important. The amount of light absorbed is pretty closely related to the cosine of the angle that the sun is 'off' of the direct. so when the sun is 45 degrees off of perpendicular the panels still get cos45 =.707 or about 70% of the available energy. (In practice it's a little less than that because not as much energy gets to the panel to be absorbed as at midday). But anyway, you can figure two hours of morning or late afternoon sun will give you as much energy as hour of midday sun. So if the panel is inside, you miss out on that available energy.
- Q: I know that there is a life expectancy for solar panels, and I suppose, the technology involved. Any information?
- Great okorder
- Q: Is there any way to charge my laptop with a solar panel? Is there any panel like that. Or if I work on panels can I do something like that. If you know anything about it, can you just help me? Thanks a lot.
- Deep Cycle Series batteries are designed to have a large amount of stored current discharged between charging sessions, with very heavy non-porous battery plates to withstand repeated major discharging and charging cycles (deep cycles). They are typically used where the battery is discharged to great extent and then recharged.
- Q: I have a solar energy panel that works in every room except mine. I have those severely bright, energy efficient bulbs and it doesn't work at all.What do I do? Is the bulbs really causing this? Why?
- It's giving off a good chunk of its energy as light in the range 800-00nm which the solar panel can efficiently harvest into electricity. As a lightbulb though, this energy is being wasted because you can't see light of those wavelengths!
- Q: How long does it take to recoup the cost of solar panels through energy savings?
- The time it takes to recoup the cost of solar panels through energy savings varies depending on factors such as the cost of the panels, the amount of sunlight in the area, the energy consumption of the household, and available government incentives. On average, it can take anywhere between 5 to 20 years to recoup the initial investment. However, with technological advancements and decreasing costs of solar panels, this payback period is steadily decreasing, making solar energy an increasingly attractive and financially viable option for many homeowners.
- Q: Can solar panels be used for large-scale power generation?
- Yes, solar panels can definitely be used for large-scale power generation. As technology has advanced, the efficiency and capacity of solar panels have greatly improved, making them a viable option for generating significant amounts of electricity. In fact, many countries and companies are already utilizing solar farms and large-scale installations to harness the power of the sun and contribute to their energy needs.
- Q: Can solar panels be installed on a government building or facility?
- Yes, solar panels can be installed on a government building or facility. In fact, many governments around the world are actively promoting the use of renewable energy sources, including solar power, to reduce their carbon footprint and promote sustainability. Installing solar panels on government buildings not only helps in generating clean and renewable energy but also sets an example for the community and encourages others to adopt green energy practices.
- Q: Is this a good kit for building a solar panel?
- Guide okorder /
- Q: Do solar panels require a battery for storage?
- No, solar panels do not necessarily require a battery for storage. While batteries can be used to store excess energy produced by solar panels for later use, it is not a mandatory component. Solar panels can also be directly connected to the electrical grid, allowing the excess energy to be fed back into the grid and credited to the owner.
