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: I have a cabin that is way out in the middle of no where, it would cost 000's of dollars to get power to it. If I have a 8,000 BTU air conditioner that runs on 25 volts and 5 amps (or 875 watts)How many solar panels will I need to run this during the day, plus charge the batteries to run it all night? How many batteries would I need
OK, in addition to the solar panels, you wil need an inverter (DC to AC; 2V t0 20V) capable of delivering 20A continuously and as much as 40A for the compressor starting surge, and a fairly large battery bank capable of delivering something over 2000 watts continuously (losses in the charging and conversion process) as well as the surge. So, if your actual demand is now calculated around 2000 watt/hour, and you need to both run the unit and charge batteries during the daylight hours - and considering that the ideal charging rate for a lead-acid battery is on the order of 0% of its capacity, you will need a huge reserve on the battery section and a huge excess on the solar section to make up for the 5 hours maximum input. So, the average high-quality deep-discharge battery will do about 400Ah @ 2.6V. Which comes to 5040 watts for one hour. For round figures, it will give you 2000 watts for 2.5 hours. You will need a minimum of eight of them just to make your system run for the 9 hours you are anticipating. Given that you do not want to run the batteries to zero each night, a 50% reserve would be a wise investment - comes to now twelve (2) batteries. Now, you will have to make 2000 watts (to run the unit) and also produce and another 8600 (per hour for five hours) watts to charge the batteries for the next night. Again, for round figures, you will need 0,000 watts of solar power, or seventy (70) panels. At ~0 watts/s.f. (00 watts/meter), that comes to about 000 square feet or 00 square meters. Modern non-crystaline panels may reduce this by 20%, or so but no more than that. You will be charging the batteries at roughly 20% of their discharge capacity - which will pretty much cut their service live in half, or so. As the average deep-discharge battery has about an 8-year life span under ideal conditions (and your situation will be far from ideal) you may expect to replace them every four years or so with good care. Much less with no care.
Q: I am working on a project and I have to build a house with solar panels. My teacher asked me how would I get solar energy if it is rainy or cloudy? I looked it up but didn't understand. Please help me!!

Q: we are doing a fundraiser to have students pledge to make donations for a solar panel instalation on one of the school buildings. I am looking for a slogan for the campain.
Build okorder
Q: Can any body tell me how much Electricity can 0 Standard solar panels produce in a day( in terms of Watts)Or else please tell me how many Watts is 5 volts of electricity?
You have to know the amperage to figure out the watts. Volts x Amps= watts
Q: Can solar panels be used in areas with high levels of snowfall?
Yes, solar panels can be used in areas with high levels of snowfall. However, the efficiency and performance of solar panels may be reduced during snowy conditions due to reduced sunlight exposure. Regular snow removal and tilt mounting options can help mitigate the impact of snow accumulation and ensure optimal energy production.
Q: im trying to run my house with with solar panels, is it possible? if so please let me know how....i have a 6000 w inverter
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: My Grandfather just purchased a cheap solar panel kit for his ranch that could not muster enough power to run his mini fridge.He has two 6 volt batteries running positive to negative and would like to add more batteries. Probably 2volt. How would he go about hooking up the other batteries and what kind of wire or coil should he use.Also, I saw on youtube a guy recommending a lead-acid battery from walmart for under $20. I was just going to go to ecology and just pick up some used batteries but I may be wrong.Any help for a first timer might help me and my gramps out will be appreciated.Thank you
Solar charger employs solar energy to supply electricity to devices or charge batteries. They are generally portable. Solar array: electrical device consisting of a large array of connected solar cells Solar Panel is a group of solar cells arranged into a panel that can be installed onto a flat surface. The panel captures sunlight and converts it into DC power.
Q: Can solar panels be installed on data centers or IT facilities?
Yes, solar panels can be installed on data centers or IT facilities. In fact, many data centers and IT facilities are increasingly adopting solar energy as a sustainable and cost-effective power source. Solar panels can be installed on rooftops or in open areas surrounding the facility to generate clean electricity and reduce their reliance on traditional grid power.
Q: How do solar panels impact the environment?
Solar panels have a positive impact on the environment as they generate clean and renewable energy without emitting harmful greenhouse gases or pollutants. By reducing the reliance on fossil fuels, solar panels help combat climate change and improve air quality. Additionally, their installation requires minimal land disturbance, and they have a long lifespan, making them a sustainable energy solution.
