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:Need help with Solar Panels (FAQ's and opinions)?
You need a plan as to what you are going to with 80 watts of power. 80w at the best, it will usually be less. One problem I have is the limited specs, you don't even know the voltage. And you get a Sharp Module but nothing else is mentioned about it. I wouldn't buy it unless you can get full specs on it and on the Sharp Module. With no specs, it's difficult to get a refund if it is defective. If you are going to store it and use it for an AC appliance, a small one, you will need: a charge controller (to control the charge into the battery) a lead acid battery (to store energy for when the sun is out) an inverter (to convert 2 volts DC into 20 VAC) and all of these cost. .
Q:What is a solar panel?
The previous answer stating that a solar panel is a method of collecting, and converting sunlight into electricity is correct, however once sunlight has been converted into electricity, it has to have a way to be stored, so that it can be used. This is accomplished by the use of storage batteries. It is stored in a DC or Direct Current form, and may then be converted to AC (alternating current) through the use of an inverter.
Q:solar panel webcam?
Q:how often do you have to replace solar panels?
Expect a water heating panel to last about the same as a water heater, 0 to 5 years. Actually, my brother's system is coming up on 5 years, and is not giving trouble yet, so maybe technology has advanced. I have actually never personally known of anyone replacing a solar electric panel due to wear-out. I have heard of occasional replacements due to accidents, including natural disasters like lightning strikes. And one brand of panels had manufacturing defects around the year 2000, but that manufacturer owned up and replaced those free of charge to their customers. A standard warranty on a solar electric panel nowadays is 25 years.
Q:Solar Panels?
Actually even if you cover your whole roof with panels, you wont get enugh power to even run a tv, fan and light at the same time. Solar panels give out a very less power output.
Q:can a light bulb power a solar panel?
Yes light-bulbs work, sort of, but you have to illuminate every cell. The output is regulated by the cell with the weakest illumination. Additionally the sun is very strong, 000W of light or more per square meter. A light-bulb is weaker, so less output. A 00W bulb may have only 5W of light, and it doesn't cover the panel, so you can expect something like % of the sun's output. The spectrum of a light-bulb is actually more appropriate for a silicon solar panel, as the silicon panel responds best to red colours.
Q:question about solar panels....?
Solar panels create a current from light. A photon strikes a crystal lattice and anelectron is freed and flows as a current
Q:Do solar panels effect birds and/or other animals?
My solar panels have provided a home for birds, they nest under them. I don't think we should worry about the glare of a solar panel when it is placed on a building that eliminated the habitat that used to be there. Glare is such a minor issue compared to eliminating food and shelter for many animals.
Q:What are the properties of Solar Panels?
Solar power Power Can Help Preserve You Money The cost of power is going up, and will only keep going up. Reaction Solar power Power Systems will help you save a large number of kWh each season by utilizing screen technology. Power created by your program are kilowatts you don't need to pay for! Every electricity program will make a number of Small-scale Technology Accreditations (STCs) upon purchase based on the size of the program and the location where it will be set up. These STCs have a market value and can be exchanged and marketed just like stocks. Power created by your solar PV program can be marketed to the lines for a top quality cost via Feed-in charges. These feed-in charges are different in every state, but the primary idea is te same, to compensate entrepreneurs of small-scale power creation. You are eligible to sell some or all of the ability you produce for more than you would normally pay for it. Would you like to decrease costs with solar power? Contact Reaction and get it done these days. Solar Power Can Help Preserve The Environment click to enlarge Producing usable direct sunlight generates no dangerous pollutants. Every season coal-fired power vegetation belch a large number of loads of as well as contamination into the weather so we can run our refigerators, toaster ovens, and have hot bathrooms. Taking your power form your own ceiling means you are no longer leading to that contamination. In fact, power companies will be paying you for electricity! Help Sydney accomplish its 5% green energy focus on by 2020 and international objectives of 20%, by changing to solar power and decreasing your own effect on international warming. Compared with other small-scale turbines, solar power is completely quiet. Turn the team radiation into power without making a audio and decrease environmental disturbance.
Q:Any tips for protecting my solar panel from high winds?
Solar panels are a costly and significant investment. Therefore, protecting them from harm should be a top priority. Unfortunately, moisture and water are common ways for solar panels to become damaged or broken. Safekeeping solar panels from both of these threats is a simple, inexpensive procedure, and doing so might save the solar panel owner a bundle if carried out correctly Instructions : Set a thick strip of silicone between each cell when putting the solar panel together, in order to prevent moisture seepage. 2: Use Plexiglas instead of glass as the face of your solar panel. Plexiglas is less liable to break and therefore safe from hailstorms or accidents. 3: Glue adhesive silicone to each side of your solar panel(s), adding additional sealant and protection from water to your commodity. :)
