Solar Module Introduction

Solar Module is the core part of solar PV power systems, also is the highest value part of it. The function of Solar Module is to convert the sun's radiation to electrical energy, or transfer it to battery and store in it, or to drive the load running.
The Product has been widely used in space and ground, it mainly used for power generation systems, charging systems, road lighting and traffic signs areas. It could offer a wide range of power and voltage, and with high conversion efficiency, and long service life.

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: we are planing to move out of the grid. we need to operate constantly 2 laptops online - does any one can tell us how much solar panels we shall need to make sure of that?: My guess is that you might find everything concerning solar power at www.okorder .

Q: ASAP :) as much details as possible: sounds like a homework essay question to me

Q: I am working on a project and I have to build a house with solar panels. My teacher asked me how would I get solar energy if it is rainy or cloudy? I looked it up but didn't understand. Please help me!!: Build okorder /

Q: I want to buy a solar panel from my house and I want to know how much it costs, what I have to buy and everything I need to know: Have you looked at these other answers? Are they kidding? You can build a do it yourself solar panel for under 200 dollars and you can add another one each time you build another one. You can have 0 solar panels built for under $2000, under $2000 that right! Just go to this web site that will give you the details. Good Luck

Q: Can solar panels be installed on multi-story buildings?: Yes, solar panels can be installed on multi-story buildings. In fact, multi-story buildings can provide ample space for solar panel installations, allowing for increased energy generation and potential cost savings. However, it is necessary to consider factors such as available roof space, structural integrity, and shading issues to ensure optimal positioning and efficiency of the solar panels.

Q: Since plants have been populating this earth for the past 475 million years I think they have evolved to gain the most sun with their greenery. If scientists used heat sensors to find the hot spots of trees and trim all of the leaves that don't quot;providefor the plant, then maybe that trimmed tree could be used to become a solar quot;panelquot;. I believe that each individual leaf could be replaced by a small solar panel and the wood of the tree would be wiring that would root all of the solar panels to a generator.: solar panels do not use generators, but i like your idea, very creative.though i don't see the practicality of this being used commercially, i think it would make a great solar promotional piece though! off-subject, it is time we stop looking at the upfront costs of things and start looking at what the long term costs are. most green-technology, although expensive at first, end up saving tons of resources and actually increase profits of businesses! studies show that people who work in a green building tend to be happier which benefits health, more excited to go to work due to the business's environmental ethics, are more productive because of natural lighting, and are more efficient because more work is getting done. green buildings can actually boost the efficiency of a business! thus saving tons of money and reducing tons of waste. Doesn't this just make sense to you?

Q: I am looking to run 2 basic shoplights, each with 2- 32 watt T8 flourecent tubes for 6 hours a day for an indoor garden. Location WI.: I doubt you will be able to get anywhere near the amount of light needed to run anything for 6 hours a day. You will probably need a battery or something as well. At the least, you will need 3 solar panels, but you will probably need more than that in order to charge the batteries to get it to last long enough.

Q: What is the cost of installing solar panels?: The cost of installing solar panels can vary depending on various factors such as the size of the installation, location, type of panels, and additional equipment needed. On average, a residential solar panel system can cost anywhere between $10,000 to $30,000 or more. However, it's important to note that there may be potential tax incentives, rebates, and financing options available, which can help offset the upfront costs and make solar panel installations more affordable.

Q: How much per sq inch do they cost? Will i have to worry about them blowing off during hurricane season? If the sun isnt out for a week will my power go out? Will I have to check them every week and check which ones arent working and replace them? Is there anyway for them to be damaged by acid rain or any type of erosion like hail? When do I have to replace them? How do I dispose of old ones (like recycling)? What is smarter and more economical having few big panels or many small ones? I know I have alot of questions but I want a good detailed answer.: They don't sell them by the square inch. It costs about $0 per watt of generating capacity. Unless you are connected to the grid you will need a battery bank to storage power for rainy days. As for the effects of weather ... you can probably make a cover out of plywood... but if your house blows away the solar panel goes with it. Before you buy one make sure your insurance covers it.

Q: I have two solar panels and I have measured that they produce V by themselves. I am trying to generate .5V, but whenever I hook them up in parallel I get something like .02V. What it happening?: You are probably wiring them incorrectly: with the positive on panel A connected to negative on panel B; and the negative on panel A connected to the positive on panel B. If you want then connected in parallel, connect the positive on panel A to the positive on panel B and the negative on panel A connected to the negative on panel B. But you will only get vdc. You can't get .5 volts from two volt sources. You can get 2 volts by connecting the panels in series.
