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:

（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:I was watching an idiot abroad, and I saw a family that lived in tent like huts, with no plumbing. And they had a solar panel, now if they can afford it, I know I can. Where do you get cheap ones?: I okorder Hope this helps.

Q:Can anyone give me some info on how to figure how many panels needed for a 0 volt 2 amp pool motor. Thanks/ Run 5 hours a day: I don't think heating a 70,000 gallon pool with solar panels is practical. My husband has designed and built our solar hot water system. It works quite well. We live in Arizona. There's no way we could heat that much water using sun energy. You have to heat the water and compete with the outside air.

Q:Can solar panels be installed on a hotel or hospitality facility?: Yes, solar panels can certainly be installed on a hotel or hospitality facility. In fact, many hotels and hospitality facilities have already embraced solar energy as a sustainable and cost-effective solution to their energy needs. By installing solar panels, these establishments can reduce their reliance on traditional energy sources, lower their carbon footprint, and potentially save on energy costs in the long run. Additionally, solar panels can be integrated into the design of the building or installed on the rooftop, making them a viable option for hotels and hospitality facilities of any size.

Q:Can solar panels be used in areas with high levels of dust or dirt?: Yes, solar panels can be used in areas with high levels of dust or dirt. However, regular cleaning and maintenance of the panels may be required to ensure optimal performance. Dust or dirt accumulation on the panels can reduce their efficiency and affect the amount of sunlight they can convert into electricity.

Q:Can solar panels be installed on educational institutions?: Yes, solar panels can be installed on educational institutions. In fact, many schools and colleges are embracing solar technology as a way to reduce energy costs, promote sustainability, and provide educational opportunities for students. Installing solar panels on educational institutions not only helps in generating clean energy but also serves as a tangible example of environmental responsibility and renewable energy solutions.

Q:Why can not the solar panel load directly?: Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.

Q:i am trying to get it to work on solar power They are outdoors and we dont feel like running a few hundred feet of power cables. Thanks and best answer will get 0 points.: Research using solar panels on stock tank water pumps. Same concept - you use a solar panel to power a remote something or other, only you would have to use a battery charged by day to run the camera at night. It does not look like you would need too powerful of a solar panel, the camera server says it needs less than 5w, no idea on the cameras, so check that out, but the whole system looks rather low power. You could easily get the necessary panels, maybe the battery too, for... I would say $200 (not in one package, you would have to get separate things). Connection of everything would be simple, no electrician needed (but keep that to yourself, depending upon state rules and regs).

Q:Are solar panels a good investment?: Yes, solar panels are a good investment for several reasons. Firstly, they can significantly reduce or eliminate your electricity bills, resulting in long-term cost savings. Additionally, solar panels are environmentally friendly as they harness clean and renewable energy, reducing your carbon footprint. Furthermore, government incentives and tax credits are often available, making solar panel installation more affordable. Lastly, solar panels can increase the value of your property, providing a return on investment if you decide to sell in the future.

Q:Can solar panels be used for air conditioning?: Yes, solar panels can be used for air conditioning. By converting sunlight into electricity, solar panels can power air conditioning units, reducing reliance on the grid and providing a renewable energy solution for cooling purposes. However, the efficiency and capacity of solar panels may vary depending on factors such as the size of the system, available sunlight, and the energy demands of the air conditioning unit.

Q:Can solar panels be installed on factories or manufacturing facilities?: Yes, solar panels can be installed on factories or manufacturing facilities. In fact, many industrial buildings are ideal for solar panel installations due to their large roof space and high energy consumption. Installing solar panels on such facilities can help reduce electricity costs, decrease reliance on traditional energy sources, and contribute to a more sustainable and environmentally friendly operation.
