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:hi, i got a pond and i am planning of putting some lights on it during night time. but i want to use solar panels and i have done a bit of research about solar panels and i know how they work, i know that the common voltage to use is 2v so you can use car batteries or deep cycle batteries, but my question is:. what wattage of bulb can you recommend2. how long it would take to drain my battery (can i have it overnight)3. and what wattage of solar panel should i get enough to recharge my battery the next day.hope anyone can help..thanks
select 2V, and it will tell you how big of a battery bank and how big of a solar panel you need. For my example, I need a 7ah 2V battery and a 20watt panel.
Q:I am looking to buy a solar panel.What does it mean when in the title it says 200 watts, or 50 watts?
You have to be realistic about the amount of power you can get from a solar panel. Solar panels only produce power when sunlight strikes them. So it's pretty obvious that solar panels don't give you any power at night, and that you aren't going to get as much power in overcast conditions, or when the sun is at an oblique angle to the solar panel, as you do in the middle of a sunny day when the panel is pointing directly at the sun. Solar panels are rated under standard test conditions. All manufacturers are obliged to use the same conditions for testing, so by comparing the rated output you can compare the performance of different solar panels. For more details plz visit : midsummerenergy .uk/solar_panel_information/solar-panel-power.html?power=50
Q:Could you have a solar panel in space that would transmit electricity remotely? Maybe have some kind of receiving antenna to pick up the energy? Perhaps there could be a string of them orbiting the Earth?Why wouldn't that work?
Wireless okorder . May be in future research will give a means to harness solar energy from space.
Q:Dear Friends, I am very much worried about Global warming, So to contribute something for reducing Global Warming I have decided to use Solar Panels. Can anybody tell me what is the price of these Solar Panels and why people are not using them when they are environment friendly. What are the Pros and Cons of these Solar Panels?
Solar okorder / And thin film solar panel power stations are about 50-60% cheaper now than solar power was in 2000. But they're still not economic in most places. Mike K's claim that solar panels produce more pollution than 'traditional' power is wrong. Coal is over 900g CO2/kWh, plus loads of pollution. Gas is ~400g CO2/kWh.
Q:Hi, I have in my sailboat 2 2 V batteries. I would like to buy solar panel(s) in order to recharge them. As i am in mexico and there is always high sun . i think it is a good idea.Usage of the batteries is very light . I have found 5-2V pannels with 80mA that fit in the sailboat. I want to know if and how i can have like 5 to 0 of them set together to charge the batteries and what other material would i need.also, i would like to know what happend if the pannels only send on 5V in a 2 V battery? Is it still charging but on 40 % of the capacity a 2 v pannel would charge or its just not doing nothing ?
0 of the panels wired in parrell will give you enough power to trickle charge the batteries. You will need a charge controller to prevent a overcharge from damaging your batteries. A panel array that is rated at 2 volts actually puts out a unregulated voltage up to 2 volts. I have bought some charger controllers from OKorder at good prices. They will also prevent the discharge of your batteries at night or when the panels are in the shade. If the panels only put out 5 volts they will not charge the batteries. Check each panel outside in the sun with a DC volt meter for proper operation before connecting them.
Q:How do solar panels affect the overall carbon footprint of a building?
Solar panels can significantly reduce the overall carbon footprint of a building. By harnessing clean and renewable energy from the sun, solar panels generate electricity without emitting greenhouse gases. This means that the building relies less on fossil fuel-based electricity, reducing its carbon emissions. Additionally, solar panels can offset the energy consumption of a building, further minimizing its carbon footprint, making it a sustainable and environmentally-friendly choice.
Q:what is a solar panel?
A solar panel is essentially a battery charger that transforms sunlight into an electrical DC (direct current)charge.
Q:a) i'd like to get a solar panel to make this thing i saw in popular science, it was a bag that had a solar panel in the side (you just attach it with grommets into a clear vinyl pocket you make. its for charging elecronics and stuff) and i was wondering what kind i should look at, do they come flexible? can i get them on OKorder? what kind of wattage should i look for (btw it also had a little voltage regulator and stuff to make a little usb in your bag) so any info on that!b) i was thinking about like putting solar panels on my roof, where can i look into that, is that a good choice, has anyone done it, how did it work out? thank you, just curious
For okorder / for information on how to hooke it up your self. It is a DIY site.
Q:Can solar panels be used for powering public transportation?
Yes, solar panels can be used for powering public transportation. Solar energy can be harnessed through solar panels and converted into electricity, which can then be used to power electric buses, trains, or trams. This approach is eco-friendly and sustainable, contributing to reducing carbon emissions and dependence on fossil fuels in public transportation systems.
Q:Can solar panels be installed on water bodies or reservoirs?
Yes, solar panels can be installed on water bodies or reservoirs. This is known as floating solar or floating photovoltaic (FPV) technology. It involves mounting solar panels on buoyant platforms on the surface of the water. This approach offers several benefits, including reduced land requirements, increased energy generation due to the cooling effect of water, and reduced evaporation from the water body.
