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: My house is aligned exactly North-South, so I have no roof facing South. Is it worth installing solar panels? Are there any good options for dealing with this situation?
The answer is NO. We can install PV solar panels to properties that are South East – South West facing. Of course it helps if you are 00% South facing but it’s not the end of the world. In fact I would say that the majority of solar panel installations across Britain are not 00% South facing.
Q: How many solar panels would it take to run an electric motor the needs 480 volts and pulls about 45 to 50 amps?
Quite a bit to run 480 volts @ 50 amps. Ohms law will give you the basic level your looking for but also you need to consider power storage ... Conversions .... Start up power vs running power levels ... it can be done but this is a bigger system then what I need so I cant just give you an number your panels will be rated in wattage and amperage you then take that power and put it in storage (battery) to inverter system (mine is 20 volt) you will need to have a 480 inverter for your power level. good luck hope I was of some help.
Q: They have been around long enough to be cheaper. Unless they are made out of a natural material that is rare and hard to find, there is no reason why they should be so expensive. On another note, I think that all low power devices like cell phones and even laptops should have solar panels. Even if it is not enough to fully power the device for a long period of time, it will provide some electricity savings and with millions of people saving a little power adds up.
We all would love to have solar panels, I wish I could afford them for my house! The fact of the matter is that the amount of energy used to make solar panels doesn't really make it beneficial. They would have to have a better way of manufacturing them, a way that uses less energy. Basically they don't make up for the energy lost in their production .Despite our efforts there is no fuel like fossil fuel.
Q: Can solar panels be used in apartments or condominiums?
Yes, solar panels can be used in apartments or condominiums. However, the installation process may vary depending on the specific building structure and ownership arrangements. In some cases, individual units can have their own solar panels installed, while in others, a shared or community solar system may be implemented to provide renewable energy to the entire building.
Q: Can solar panels be used for powering a water treatment plant?
Yes, solar panels can be used to power a water treatment plant. Solar energy can be harnessed and converted into electricity to provide a sustainable and renewable power source for operating the various equipment and processes involved in water treatment. By utilizing solar panels, water treatment plants can reduce their dependence on traditional energy sources and contribute to a more environmentally friendly and cost-effective operation.
Q: All I want to power is a small ice-maker (250 watts) for 25 minutes per day. That's all!!!Can I do that by using a 00 watt panel with 2-3 deep cycle batteries and getting 0 hours of quality light per day.(BTW) what size converter would you recommend? I want more than I need to grow the system

Q: I was told by a veteran that jcpl had a program that installs free solar systems for disabled vets.If this is true who do i contact?
Guide okorder
Q: i was reading the popular science magazine and i saw that they might make a Sun Powered it Absolutely NOT possible to make a car with a Solar Panel? I dont see any harm in making it..
it's possible, but the oil company don't want you to, besides solar-powered cars need to be quite big to have those panels mounted on to provide the needed power, thus it'll take up alot of space on the road. they can't be as powerful as gas-powered cars in terms of speed hauling power. maybe they should make 2-seaters for city users, that'll cut down on the pollution ease up the gas prices. of course, they can make a hybrid car that uses an alternative power, like gas/solar or dry cell/solar to solve the problem... parking-meters with a power-plugs for you to recharge while you park.
Q: How do solar panels impact the environment?
Solar panels have a positive impact on the environment as they generate clean, renewable energy without emitting harmful greenhouse gases or pollutants. They help reduce reliance on fossil fuels, decrease air and water pollution, and combat climate change, making them a sustainable and environmentally friendly choice for energy production.
Q: How much roof space is needed for solar panels?
The amount of roof space needed for solar panels depends on several factors, such as the size and efficiency of the panels, the energy needs of the household or building, and the available sunlight in the area. Generally, it is recommended to have around 100 to 400 square feet of unshaded roof space per kilowatt of installed solar panels. It is best to consult with a solar professional to determine the exact roof space requirements for your specific situation.
