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: And I'm tring to decide if I should buy it. Let's say my house would need Megawatt per hour. That's 000 megawatts per hour. This solar panel produces 36 watts. I don't know how if that means per hour or what???: Build okorder /

Q: If a solar panel (using 36 3x6 solar cells) puts out 60 watts, how many panels would I need (for a house) if I use a max of 2300 kWh in a month? I checked my electric usage for the past 2 years and the kWh is usually lower but I wanted to use the most kWh used (2300) for my question. Thanks!: Good question. Something to keep in mind is that modern solar electric works _alongside_ the grid, so you don't need to displace your entire 2300 kWh. The best financial return, if any, might come at a point where you generate only 500, 000, or 500 kWh per month. How many panels you need strongly depends on your location. Speaking for the location of my house in San Jose, Ca, that amount of usage would be about a 2 kW array, and if you divide 60 into that, you get 200 panels. In a perfect location, you would need slightly less, in a northern state, you might need double that. If this was a real project, you would probably not use 60-watt panels. The choice of panels is not simply a matter of getting enough watts. 2 kW is a large system today for residential. The usual advice is to go for energy efficiency first, then consider solar after the usage is down.

Q: who has solar panels on their home and are they worth it: Depends where you live. Solar hot water is good for anywhere that doesn't get hard freezes, and will also work (slightly different technology) in colder areas, but will take longer to pay back. Hawaii probably has the best payback for solar water heaters of any state.

Q: Solar panel packages have different levels of power. For instance you can get a kw system but is this kw per hour or day. How does this work?: it would be an instantaneous rating at maximum output. To get the the amount of power produced, you would multiply the number of hours at near peak output. kw X 5 hours = 5kwh or about 50 cents of electricity.

Q: I want to make 2V 4.5A solar panel to charge my battery used in my RC car project. I just like to know how should I amplify the current for 4.5A. I need the total circuit diagram. Can anyone help me. Please. I need some affordable methods please.: Have okorder / . It could obviously explain everybody!

Q: Is there such a thing as portable solar panels? Can these be obtained for say a mobile homes / caravans etc.: Yes there are lots available in many different types for instance take a look at www.okorder

Q: Are there any government incentives or rebates for installing solar panels?: Yes, there are various government incentives and rebates available for installing solar panels. These incentives can include federal tax credits, state and local grants, and utility rebates. These programs aim to encourage the adoption of renewable energy sources and can significantly offset the upfront costs of installing solar panels. It is advisable to check with local authorities and utilities to determine the specific incentives and rebates available in a particular area.

Q: I have a solar panel 7.5V .25W 50mah, connect 2 in parallel to power a RC boat. The boat use to run on 6cell battery pack - 7.2V 800Mah.The dc motor requirement based on the provided battery pack, i assume would be 7.2V and rated at (7.2V * .8Amp) = 2.96 Watt.Would two of my solar panels run this DC motor ?are my calculations or understanding correct ?do lend a hand dear ''world'': Wood? Steel tubing could be a lot lighter. Use the hardest narrowest tires you can find bicycle wheels and tires would work nicely and they can be had with really light disc breaks. As for a motor a golf cart motor is made to order. You can get an old electric golf cart and have almost all the parts you will need. Hell cover the roof of the cart with photo voltaic and have a ball. Note I stress weight savings as weight will cost you energy and with photos you won't have much to spare. You will need a battery pac of some sort lithium are a better choice than lead acid. there is a ton more to consider good luck with your project.

Q: Can solar panels be used for street lighting?: Yes, solar panels can be used for street lighting. Solar-powered street lights use photovoltaic panels to convert sunlight into electricity, which is then stored in batteries for use during the night. This renewable energy source helps to reduce electricity costs and carbon emissions associated with traditional street lighting systems.
