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: what do I need to do to disconnect a solar panel from a battery to protect the panel?
Know that solar panels almost always incorporate a blocking diode to prevent a battery from back-feeding through an un-illuminated panel. Know that solar panels are usually connected to a battery via an electronic switching charge controller, not directly connected. Know that when a solar panel is open-circuited (disconnected from everything) it's terminal voltage will rise to almost twice it's nominal voltage. (22V is common for a 2V panel), unless it is stored in total darkness.
Q: Hi, I am starting to get curious about the pros/cons of installing solar panels - has anyone done it and is it worth it?
Solar is mroe expensive than just about every other form of generation for a centralized plant, but can still be cost-effective for a consumer living in the right place. This is because while a coal-fired plant may produce electricity for 2-3 cents per kWh, by the time it's marked up to retail, distributed, and taxed to get to a residence, it may be 5 cents per kWh - a figure which solar can match in many places.
Q: Can solar panels be used to power a telecommunications network?
Yes, solar panels can be used to power a telecommunications network. Solar power is a sustainable and renewable energy source that can be harnessed to generate electricity for various applications, including powering telecommunication infrastructure. By installing solar panels, the telecommunications network can operate with minimal reliance on the grid, reducing energy costs and environmental impact. Additionally, solar power can be stored in batteries to ensure uninterrupted power supply even during periods of low sunlight.
Q: Can anyone give me a link to a website that sells really big solar panels? Enough to run a small cafe on entirely solar power.
I think you may be surprised how much energy a little cafe like that uses. Since the air conditioning, refrigerators, and other appliances are going nonstop, I'd expect the energy usage to be several times that of a normal house. If you have access to the electric bills of the cafe while it was in operation, look up the kWh's used per month. For scale, I will say that our house uses 500 kWh per month, and needs 3 kW of panels to keep up with that. Scale up to match the restaurant, as a ballpark estimate. If you don't have access to the electric bills, then go visit a similar cafe in town, or a nearby town, and ask them how much their electric bill is. If the ballpark estimate still looks doable to you, then contact a professional solar installer to get an accurate, no-obligation estimate. Most likely, the cafe will use gas heat for cooking. But if not, electricity from solar panels is probably the most inefficient way to cook. Consider having solar ovens for most of the cooking, if you have land, with gas as a backup on cloudy days.
Q: Are solar panels safe for the environment?
Yes, solar panels are safe for the environment. They produce clean and renewable energy by converting sunlight into electricity without emitting harmful greenhouse gases or pollutants. Additionally, the manufacturing process of solar panels has become more sustainable over time, reducing their environmental impact.
Q: Can solar panels be used in areas with high levels of pollution from transportation?
Yes, solar panels can be used in areas with high levels of pollution from transportation. While pollution can affect the performance of solar panels by reducing their efficiency, they can still generate electricity even in polluted areas. Regular cleaning and maintenance of solar panels can help mitigate the impact of pollution on their performance. Additionally, installing solar panels in areas with high pollution can contribute to reducing the carbon footprint associated with transportation and help improve air quality over time.
Q: Do solar panels work at night?
No, solar panels do not work at night as they rely on sunlight to generate electricity.
Q: Can solar panels be easily removed and relocated?
Yes, solar panels can be easily removed and relocated. They are typically designed to be modular and can be disassembled and reinstalled in a new location with relative ease. However, it is important to consult a professional to ensure proper disconnection, transportation, and reinstallation to maintain their efficiency and safety.
Q: And how do you choose the best one for the best price?I saw a 400 watt monocrystalline solar panel
In regards to my research about these two types of Solar Panels, I suggest that the Monocrystalline Solar Panel would be great! It is affordable and also more convenient to install. Using a 400W Panel means fewer panels and less installation time, in addition to fewer connections and transmission losses which results in big savings and a faster return on your investment.The Topsun Solar Panels boasts efficiency of up to 6.77% and use cutting edge technology for the best heat dissipation in the industry.
Q: Are solar panels worth it?? I mean the price you by for them up front is a lot, so you properly need a loan for it. So how does it work? Won't the loan be just as much as you electric bill?Im just really confused about it.
solar panel is a good product which can use clean energy and convert it into electricity for people use. and will decrease the pollution to the environment.
