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: My home uses an average of 2400 kW per month (28,800 per year.) How much can I expect it to cost to install solar panels of this amount? (It is not my intention to go off of the electric company's grid. I would like to generate what I can / possibly sell back extra power)What quot;hiddencosts are there? What is the average life of them?What is the quot;best(cost effective and green) solution / approach?(BTW.... I am in southern LA if that makes a difference)Best answer will go to clear answer WITH links/resources to back it up!)THANKS A MILLION!!! I hope you have a safe and happy holiday season!!!
Power inverter to change 2VDC panel power to 220VAC House power. (~$600) You are also going to need various switches and a meter to keep track of how much you are sending back to your power company. Final answer... Expect to pay ~$7,000.00 with installation by a qualified electritan.
Q: Are there any tax credits available for installing solar panels?
Yes, there are tax credits available for installing solar panels.
Q: My family and I are looking into solar panels for our home. But I'm unsure how it would be priced. This month our home used ,623 kwh. The solar panel company said we should expect $6-$9 per watt used. What would that put as at?
With out doing the math,, I think I would ask the solar panel company to explain it to you as they are trying to sell it to you. And see if you have some sort of warranty of savings. Make them work for the sale!!
Q: I made three 36 solar cell (3x6 .5V 3.5A) panel and had it hooked a up to an old car inverter. I was on line looking for a cheap grid tied inverter. I came across the Enphase micro inverter and was wondering if i could use one of those. Will it work?

Q: Can solar panels be installed on historical buildings?
Yes, solar panels can be installed on historical buildings. However, it requires careful planning and consideration to ensure that the installation does not compromise the building's historical integrity. Various techniques can be employed, such as integrating solar panels into existing structures, using non-penetrating mounting systems, or placing panels in less visible areas. Preservation guidelines and local regulations should be followed to maintain the historical significance while promoting sustainable energy.
Q: Can solar panels be installed on a church or religious building?
Yes, solar panels can be installed on a church or religious building. In fact, many religious institutions have embraced solar energy as a sustainable and environmentally friendly solution to meet their energy needs. Installing solar panels on these buildings not only helps them reduce their carbon footprint but also promotes a message of stewardship and responsibility towards the planet.
Q: What is the typical warranty period for solar panels?
The typical warranty period for solar panels is around 25 years.
Q: What is the proper diode to use on an 5v 500ma solar panel?
At least a 2 amp diode. rated above the 2 volts that are commonly found on the market. A blocking diode must be able to stop a higher current and voltage than the panel maximum. A diode will work on any voltage and current lower than it rating.
Q: The intensity of sunlight at the distance of the Earth's orbit is 380 W/m2. An Earth-orbiting satellite has a solar panel that measures .35 m by 4.86 m, which converts solar energy to electrical energy with an efficiency of 26%. In one hour, how much electrical energy does the panel produce? Assume that the satellite's attitude control jets keep the panel oriented perpendicular to the incoming sunlight.
380 W/m2. An Earth-orbiting satellite has a solar panel that measures .35 m by 4.86 m, which converts solar energy to electrical energy with an efficiency of 26%. In one hour, how much electrical energy does the panel produce? 380 W/m? x .35 m x 4.86 m x 0.26 = 2354 watts energy is watts*time E = 2354 watts x 3600 sec = 847472 Joules or, E = 2354 watt-hours
Q: can i put a solar panel on a projector. if nt wat is a low energy projector that i can watch movies and play games on
Solar panels put out DC voltage, like a battery. The projectors that plug into the wall require AC voltage. Unless you got a travel projector that plugs into a cigarette lighter (does that exist?), you would need to convert the DC power from the solar panel to AC for the projector with an inverter. And if you want to use it when the sun isn't shining, you'd need batteries to store the power.
