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:

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:0W solar panel can use on what?
Graham is on the right track. However, you need to factor in a 80% DC to AC conversion loss. But yes a 0W CFL is about the size of it... Harbor Freight sells a system consisting of panels, battery, inverter, and TWO CFL's for $250. (You can power 2 CFL's off the grid for a very long time for $250)
Q:How do you use solar panels?
Custom solar-heating systems are unique. Does yours have a circulating pump? Does it have a storage tank? Is the fluid that goes to the panels separated from the household water and transfers heat through a heat-exchanger radiator, and the fluid has antifreeze in it? If it does, is the antifreeze of the variety that won't poison your family if there is a leak? Does your system have a thermostat-controlled pump that turns on when the water in the panels are hot? Does it have a limit-thermostat to turn off the pump when water in the storage tank is hot? There are many more variations to operation of solar-heating panels. Find out who designed it or who knows how to operate it and ask them.
Q:how long does it take for a solar panel to make one watt?

Q:What kind of Solar Power panel setup do I need for this?
Unfortunately solar panels are low output,generally only 2 volt and very low amperage,so you would need to build a multi panel array with a DC-AC converter all together costing several hundred dollars which would only work during sunlight.Just roughly figuring,about $800. Plan2-Solar charger,battery bank,and DC-AC inverter so it would work 24hrs a day,also several hundred $$. Solar power does just not seem feasible(to me)in this application.By far the cheapest set up here would be an extension cord fromhouse to the bucket.260 watts per hr is a fairly lightweight draw,even not figuring the thermostat's cycling it on and off as needed.Electricity is sold in kilowatt hours(000W/hr).This bucket would use(not allowing for thermostats control lowering it)appx 6000watts or 6KW per day.Depending on your electrical cost per Kwh it would cost very little to run.(In my location appx 50cents a day) or appx the same amount as my computer(325watts total)) Note that that would be a maximum rate,and would actually be less due to thermostat cycling off and on as needed.
Q:Can I get free solar panels?
Do not touch free solar panels with a barge pole. The installer keeps the feed-in tariff and owns the panels on your roof, a problem when you come to sell the house. Your only benefit is the free use of the electricity generated, if you happen to be in, or use time clocks, on dish washer, washing machine etc. My system has a target of 6 kWh per day. At 43.3p per unit this is a theoretical payment of £6.92 a day. All you could gain, assuming you use every available kWh generated, would be £.92, assuming a tariff of 2 p per kWh. The feed-in tariff goes down for new installations next April. In my opinion its a good buy, and should show an 8% return on our investment. I would not like to give the main benefit to someone else.
Q:does vibration affect solar panels?
probably not much. If you had it at an optimal angle to the sun and it vibrated out of that position then you could be loosing some efficiency.
Q:How to wire solar panels?
You will have to wire them in such a way that provides the battery with the optimal voltage for it to charge, which on a car 2v battery is around 4v. You said you have some background in electronics so this shouldnt be too difficult. You can connect them straight to the battery yes. Like you said, I believe a power inverter from 2VDC to 0VAC would work just fine. PS3 pulls a lot lot lot of current though so it probably wouldnt last too long. Look up the specs for PS3 and see how many amps it is pulling and purchase your inverter based off of that. I remember trying to run an xbox in my car one time and the inverter I had didnt work because of that. Be careful working with batteries, I had one explode in my face about a month ago.. scariest moment of my life! Good luck!
Q:What type of wires should i use for a solar panel?
6 gauge wire would be a good size. Just solder it on and run it wherever you want.
Q:Should the value of solar panels be included when appraising a home?
Are you trying to sell it - is that why you're wanting to change the appraised value? Your home is only worth what someone is willing to pay for it. Before anyone buys it, they'll have their own appraiser make an evaluation. Rarely do you get back upgrades $$$ when you sell. This likely includes solar panels.
Q:Do grid-tied solar panel systems have to be installed professionally?
For safety purposes and liability, I do suggest that you should hire a professional solar panel installer. The solar panels has a lot of engineered like work, So better hire someone who has a fully aware for this work.
