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:How to build solar panels?

Q:How much would solar panels cost for these?
in case you recognize the place to look you get get image voltaic panels for 0 expenses. as an occasion, numerous sign companies use image voltaic panels. touch your interior sight sign company and tell them you will haul off all their broken image voltaic panel for loose. they're oftentimes extra beneficial than keen to assist you are trying this.
Q:How can I run my house purely off of solar panels?
I ve been researching this myself! I need appr 6000w per year. I live in MN which a zone 5 on a solar map (4.4 hrs of sunlight per day). I would need 56 panels at 300w each!!! pffft - I d be dead before I recouped my cost, plus my roof isn t even that big! Sure, I can reduce my bill, but then again the $ to reduce it..... I m now looking into wind turbine since it always seems windy here.
Q:solar panels for my home.?
the st element to comprehend is that there is no longer something complicated some photograph voltaic panel. this is not something greater beneficial than a selection of of photograph voltaic or PV cells on a board this is suited for the main spectacular area of your abode, generally on the roof. There are publications obtainable that coach you the thank you to construct a photo voltaic panel and a windmill for basically $a hundred and fifty, and it’s truly difficulty-free to make. appropriate of all, you may save 70% or greater on your potential invoice, including as much as hundreds of dollars each and each 2 months in reductions. I reviewed the two unfastened publications and paid publications and have arise with our ideal to construct your individual photograph voltaic panels.

- Radiation from the sun is mostly Ultra- Violet. - There are 2 types of solar panels, Solar thermal collectors and photovoltaic cells. - Put simply, photovoltaic cells take the UV rays and produce electricity. - Solar thermal collectors (which is probabl
Q:Solar panel help please?
Solar water heating is low technology. There are do it your self plans for it all over the internet. There is no electricity involved. Simply laying a garden hose on the ground in the hot Sun can heat the water to really high temperatures. Just have a shutoff nozzle on the hose, turn on the tap and open the nozzle until water comes out and then close the nozzle at the end of the hose. Let the hose full of water sit in the sun for an hour or so and then open the nozzle and feel how hot the water is that comes out. Be careful, because it can be so hot you can get a burn! When the gallon or so that can fit in the hose has all come out and is replaced by other water from the tap, it will feel cold again. Close the nozzle and wait another hour to heat it up again. A solar hot water heater is just a very long coil of pipe in the Sun, maybe with a pump to slowly circulate water from a holding tank so you can make and store more hot water that fits in the hose. Solar electric power is completely different. It uses semiconductor devices called solar cells to make electricity directly from light. Many of solar cells are usually arranged into large panels to make larger amounts of power. In electricity, Watts = Volts * Amps. Battery capacity is usually measured in Amp-hours. Small solar panels are often designed to produce electricity at 2 volts. A 60 Watt, 2 volt panel makes 5 Amps of electric current, because 2*5=60. So if you use it to charge a 2 volt battery with a capacity of 5 Amp-hours it will take hour to charge. A 0 Amp-hour battery would take 2 hours to charge with the same panel.
Q:Are DIY Solar panels legitimate for saving electricity?
Your location could effect this answer significantly.If you are in an area that requires considerable amounts of heating,and you are looking to save some money with a homemade project,try solar-thermal.S-T is easy and cheap ,can be built from common scrapyard materials,and will give you a great knowledge gateway . The orientation and tracking skills you will learn can be used later with PVs if you choose,or you can make better concentrators for the solar-thermal and build yourself a sterling or rankin cycle engine to generate electricity.If u need heat,or even hot water, u can start saving the money u put into the system immediately. Concentrated PV is here and now ,but, in a year or 2 it will be cheap and readily available and thats when PV will start to approach the efficiency of solar-thermal.there a great sites and groups on just S-T out there ,join 'em,check 'em out,read the free info from those who have built working systems,and you will probably find a more useful method of saving money and the planet at the same time.Just remember to approach it as a hobby/learning experience at first.Start with solar-thermal....theres a reason the anti-greenies point at the ROIs on PVs,great arguement against alt energy,but over the last 30 years I've shut up quite a few skeptics with my solar-thermal projects ,esp. when coupled with geothermal...have fun,make a local scrapyard owner/worker ur freind..................GEOD
Q:Do solar panels make electricity from light intensity or watts?
For a particular solar panel, you can't choose between the intensity and the power in terms of which determines the energy produced in a given time, because the two concepts are related. Intensity is the power per unit area. So if you have twice the intensity on a particular panel, solar energy is being delivered at twice the rate. However, if you were to compare two solar panels on which the same light intensity was falling, the panel with greater area would produce electrical energy at a greater rate, as power in intensity times area. In that sense, I'd say that the solar power input determines the electrical power output.
