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:

（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:Can solar panels be used on a backpack or portable device?: Yes, solar panels can be used on a backpack or portable device. These panels are designed to be lightweight and flexible, making them ideal for use on backpacks or other portable devices. They can convert sunlight into electricity, allowing you to charge your devices on the go, making them a convenient and environmentally-friendly option for powering your portable devices.

Q:How much electricity can a solar panel produce?: The amount of electricity a solar panel can produce depends on various factors such as the size and efficiency of the panel, the amount of sunlight it receives, and the location. On average, a standard solar panel can produce anywhere between 250 to 400 watts of electricity per hour.

Q:260 watt solar panels on an rv?: What are you going to power with your 260w solar panels? Tools? They generally use more than 260w. The panels will generate electricity. The problem is that your tools likely don't use DC. And if you're asking here, it's not likely that you have the background to hook everything up correctly. You'd need both batteries and a pretty good sized inverter.

Q:How much space do I need for solar panels?: The amount of space you need for solar panels depends on various factors such as the size and efficiency of the panels, your energy requirements, and the available sunlight. Generally, you'll need around 100 square feet of unobstructed roof space per 1 kW of solar panels. However, it's best to consult with a solar installer who can assess your specific needs and provide an accurate estimation.

Q:Can solar panels be installed on carports or pergolas?: Yes, solar panels can be installed on carports or pergolas. In fact, these structures provide an ideal space for solar panel installation as they offer ample sun exposure and can optimize energy generation while providing shade or protection for vehicles or outdoor spaces.

Q:Can solar panels be installed on data centers?: Yes, solar panels can be installed on data centers. In fact, many data centers are increasingly adopting solar energy solutions to reduce their carbon footprint and dependence on non-renewable energy sources. Installing solar panels on data centers helps generate clean and sustainable electricity, thereby promoting environmental sustainability and cost savings in the long run.

Q:I know that if I put solar panels in my home I will get 30% back from the govt. Does that mean if I pay 2K I will get back around a 3K check? Or will my income play a roll where I may not get back as much?: Not a good answer: CNBC had a news bit, that it can take 0 to 20 years for you to break even in energy costs after installing solar panels. Please don't buy them just for the tax deduction. See if you can google a calculator for this - do research. I have a brother in law that buys anything under the sun just because he gets a tax deduction. I'm sure you're not like that though. Run the numbers of what you will save vs the 2K you will spend You may never break even

Q:wondering if i should get them?? not sure if its worth leasing? also anyone know anything about solar city?: They are absolutely worth it. I had a town house in Boston with solar panel shingles and they were able to supply enough energy for me to feed back the grid-- literally making money off of them. I am building a very large home in the suburbs now and we are doing solar shingles on that. Our contractor estimated that with our geotherm heat pump and energy efficient lighting we should still be able to throw back more energy to the grid all year round! As for leasing it is not worth it. For one thing, most leasing contracts prevent you from selling your energy to the grid yourself but rather they take a cut. But a bigger issue: the government gives you a tax credit on solar panel installations but only if you purchase them! I did the math myself the first time I did solar panels and with the tax credit I saved 25% over leasing. Something else to consider is that with your own panels you can connect a variety of other systems to your home and modify them as needed.

Q:How do solar panels affect the homeowner's insurance policy?: Solar panels can have an impact on a homeowner's insurance policy as they are considered an additional structure or improvement to the property. While they may increase the overall value of the home, they also introduce potential risks such as damage from storms or accidents. Homeowners should inform their insurance provider about the installation of solar panels to ensure adequate coverage and potentially adjust their policy accordingly.

Q:I'm curious to know if the small solar panels on a calculator (ie TI-32) could produce a voltage similar to what is used in a single-use (disposable) camera, approximately 4V.: It isn't Volts that matter if you're trying to put the calculator solar panel on the camera. It would be the amps. The calculator's solar panel will put out however many volts or very close to what the battery puts out. If you want you can test it out with a Volt/Ammeter. You see, those cameras use 2 double A batteries. They are going to put out a higher current than the small dime shaped battery in the back of your calculator; a higher voltage perhaps too. Those disposable cameras have a photo flash capacitor in them that has to charge. You can hear them charge up when you tell it to turn on the camera's flash. Sounds like a winding then the little orange light comes on. That light means the capacitor is charged. You SHOULDN'T be able to change out the batteries in the camera with a solar panel from a calculator without having to wait days for that flash capacitor to charge. Sorry. EDIT: HOWEVER, you can take multiple solar panels and wire them in a parallel circuit to get more current(amperes) or wire them in a series circuit to get a higher voltage. If you were to do this you could power whatever you wanted with them. Even your house if you were to get a rectifier to convert the power from DC to AC.
