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:I have a solar panel that puts out 00v, .5 amps in full sun. Before I thought it would charge a 2v battery without a solar charger but then I talked to someone and they said that it was wasting a lot of power and could potentially hurt the battery. A second part to this question is what happens if I put it on a 72v battery without a controller. Thanks!

Q:Can solar panels be installed on waste treatment plants?
Yes, solar panels can be installed on waste treatment plants. In fact, waste treatment plants provide ample space and suitable infrastructure for the installation of solar panels. This can help offset the electricity consumption of the plant and reduce its carbon footprint, making it a sustainable and environmentally friendly option. Additionally, solar panels can contribute to cost savings by generating clean energy on-site.
Q:Can solar panels be installed on a museum or cultural institution?
Yes, solar panels can be installed on a museum or cultural institution. Installing solar panels can help these institutions reduce their energy costs and carbon footprint, while also showcasing their commitment to sustainability and environmental stewardship. Additionally, solar panels can be installed on rooftops or in nearby open spaces, minimizing any aesthetic impact on the museum's architecture or surrounding areas.
Q:What direction do solar panels usually point? North? East? South? West?
South in the northern hemisphere. - this gives you sunlight on the panel a major portion of the day without the need for a mechanism to follow the sun or change direction from E to S to W as the day progresses
Q:Can solar panels be installed on agricultural irrigation systems?
Yes, solar panels can be installed on agricultural irrigation systems. They can provide a sustainable and renewable source of energy to power irrigation pumps, reducing reliance on fossil fuels and lowering operational costs for farmers. Additionally, solar panels are compatible with various irrigation system configurations and can be easily integrated to support the water needs of crop production.
Q:Can solar panels be installed on a tennis court or sports complex?
Yes, solar panels can be installed on a tennis court or sports complex. These areas often have large open spaces with ample sunlight, making them ideal for solar panel installations. Additionally, integrating solar panels into sports facilities can help offset energy costs and promote sustainability.
Q:Can solar panels be used in areas with high levels of wind-blown debris?
Yes, solar panels can be used in areas with high levels of wind-blown debris. However, it is important to install the panels in a way that minimizes the impact of the debris. This can be achieved by using protective measures such as installing wind deflectors or choosing panels with stronger frames and tempered glass. Regular maintenance and cleaning may also be required to ensure optimal performance in such conditions.
Q:How do solar panels impact wildlife?
Solar panels have minimal impact on wildlife compared to other forms of energy generation. While there may be some concerns about the disruption of habitats during installation, once operational, solar panels do not emit greenhouse gases or pollutants, reducing air and water pollution that can harm wildlife. Additionally, solar panels typically occupy a small fraction of land and can be installed on rooftops or in areas with limited biodiversity, minimizing the impact on wildlife habitats.
Q:How can solar panels be used for heating water?
Solar panels can be used for heating water by capturing sunlight and converting it into electricity. This electricity can then be used to power heating elements or heat pumps that warm up water for various purposes, such as domestic use or swimming pools.
Q:Can solar panels be used for powering a manufacturing facility?
Yes, solar panels can be used to power a manufacturing facility. Solar panels convert sunlight into electricity, which can be utilized to run various equipment and processes within a manufacturing facility. By installing a sufficient number of solar panels, a manufacturing facility can significantly reduce its reliance on traditional grid electricity and lower its carbon footprint. However, the feasibility and effectiveness of solar panels for powering a manufacturing facility would depend on factors such as the facility's energy requirements, available sunlight, and the size of the solar panel system installed.
