Solar Module Introduction

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:

1What price for each watt?

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

2What 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.

3Can 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.

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

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

5Have 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.

6When 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.

7Can 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.

10Can we visit your factory?

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

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.
A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
Q: Can solar panels be used on commercial buildings?
Yes, solar panels can definitely be used on commercial buildings. In fact, many businesses and organizations are increasingly adopting solar energy as a way to reduce their carbon footprint, save on energy costs, and demonstrate their commitment to sustainability. Solar panels can be installed on rooftops, carports, or open land surrounding commercial buildings, providing a clean and renewable source of electricity.
Q: Can solar panels be used to power a data center?
Yes, solar panels can be used to power a data center. Solar panels convert sunlight into electricity, which can be used to power various devices and infrastructure, including data centers. By installing a sufficient number of solar panels and using energy storage systems, a data center can be powered entirely or partially by solar energy. This can help reduce reliance on traditional power sources, lower energy costs, and promote environmental sustainability. However, the feasibility and efficiency of using solar panels for powering a data center may depend on factors such as the location, size of the data center, and the availability of sunlight.
Q: Hi.How efficienent are solar panels? I mean, suppose we install a kw panel.. Wil it produce 5kw in 5 hours of good sun light?Or like if its 80 percent efficient, wil it produce 4kw and so on.Also, do the chinese solar panels give the same results as compared with panels from other countries?I live in india, so we get plenty of sunlight during the day.Thanks

Q: i want to know how to hook up solar panels to my existing power. all i can find on the internet is to use batteries and a inverter. but i want to use all of my existing lights and outlets off of the solar energy. i have heard that you can actually turn the meter backwards and use supplied power when needed. thats what i want to do and is it possible to do myself and if so, how?
Contact your power company. They will advise you of the proper configuration. If you try to attempt this without notifying the power company and something goes wrong, they can and most likely will hold you responsible for all damages.
Q: Can solar panels be recycled?
Yes, solar panels can be recycled. They are made of materials like glass, aluminum, and silicon, which can all be reclaimed and reused. Recycling solar panels helps reduce waste and environmental impact, while also recovering valuable resources for future production.
Q: i am starting to consider getting solar panels instead of paying electric bills which are somewhat higher now than they used to be
Yes its true! electric bills are getting higher and higher. That's why a lot of people or businesses turn to alternative sources of energy. It is a little cheaper but can still provide the same level of energy. It is even good for the environment. If you are considering a switch for your energy provider, learn first about the different alternative sources of energy at businessswitchonline .uk. It might be helpful in making up your decision. Also, solar panels will depend on how large your house is or if it is really qualified for solar energy. You need an energy provider to have an evaluation of your house before you set up a solar panel.
Q: Main questions: How can I work out the efficiency of a solar panel and how can I work out if the panel is relatively cost-effective? Also what type of solar panels is considered most effiecient?Let's assume that all relative values are available.Secondary question: What type of safety regulations and licenses are required to be fulfiled in order to import solar panels into the EU from non-EU countries?
366 W/square meter on March 2 and tweaked based on lattitude eff = W out/Sun W in there are special heat meters to measure W in ======== IEC 62688 Certification; and UL cert in USA
Q: What is the impact of roof shading on solar panels' efficiency?
Roof shading has a significant impact on the efficiency of solar panels. When a roof is shaded, whether by nearby trees, buildings, or other obstructions, it reduces the amount of sunlight reaching the panels. This shading creates areas of lower or no sunlight, resulting in decreased energy production. Therefore, minimizing roof shading is crucial to maximize the efficiency and overall performance of solar panels.
Q: How are solar panels made?
Solar panels are made using a multi-step process that involves the production of silicon wafers, the application of various layers and coatings, and the assembly of individual cells into a panel.
