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:
(1)What price for each watt?
It depends on the quantity, delivery date and payment terms.
(2)What 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.
(3)Can 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.
(4)Do you have the CE, TUV, UL Certification?
We’ve already passed all the tests, and any certificate is available.
(5)Have 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.
(6)When 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.
(7)Can 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.
(10)Can we visit your factory?
Surely, I will arrange the trip basing on your business schedule.
- Q: Solar panels do good more then bad?
- It is like running a single large power plant instead of all of us having our home small fossil fuel electricity generators. You can have better and effective environment at a single source at large scale then at smaller sources. Most would just not care much. On separate line if the solar panels were to become more common in use, industries will be efficient and environment friendly ways to make them. Thus increasing their effectiveness as good green cause.
- Q: Do solar panels require a specific orientation or angle for optimal performance?
- Yes, solar panels do require a specific orientation and angle for optimal performance. Generally, it is recommended to install solar panels facing south and at an angle equal to the latitude of the installation location. This allows the panels to receive maximum sunlight throughout the day, maximizing their energy production. However, panels can still generate electricity when facing other directions or at different angles, although their efficiency may be slightly reduced.
- Q: How much space do I need for solar panels?
- The amount of space needed for solar panels varies depending on the size and capacity of the panels. On average, a typical residential solar panel system requires about 100-400 square feet of roof space, but it can also be installed in a backyard or ground-mounted depending on available space. It is best to consult with a solar installation professional who can assess your specific needs and determine the exact space requirements for your solar panels.
- Q: What i would like to know is if you were using commercially available solar panels, clustered as close together as possible and spread out on one acre, how much electrical energy is produced? if u can 'translate' this into terms of ( hour of average daylight = powering a ____ for X units of time)
- Solar Power Per Acre
- Q: Monocrystalline panels are sooo expensive! Thanks for reading.
- Since you are asking for a rather technical answer you should be aware that solar panels come in several varieties. Two broad categories are photovoltaic panels which have achieved marketable efficiencies of around 24% and solar thermal panels which are routinely achieving efficiencies of between 60 to 80% while they are also much cheaper than photovoltaic panels. So the short answer is solar thermal panels. But what can you do with solar thermal energy. The answer is just about everything you can do with light energy. Sometimes additional equipment makes the efficiency drop to near that of photovoltaic panels. The trick is to keep the devices as simple and as efficient as possible. Solar thermal can of course be used to heat our homes. But it can also be used directly for air conditioning. The type of air conditioner uses a slightly different principal but it is one of the oldest that was once used in ice houses before refrigerators. It is known as an absorption system. At some point you may want to make electricity from the sun's heat. The most efficient commercial systems are not photovoltaic but solar thermal. There are several commercial systems where increased scale improves efficiency. The most efficient is a solar parabolic dish system combined with a stirling engine. At around 30% efficiency it beats photovoltaic and other thermal systems. At this level of commercial development, the various systems are more often described as solar collectors rather than panels.
- Q: Can solar panels be installed on a military base or facility?
- Yes, solar panels can definitely be installed on a military base or facility. In fact, many military bases around the world have already adopted solar energy as a means to reduce their reliance on fossil fuels and increase their energy independence. Solar panels can be installed on rooftops, parking lots, or open fields within the base, providing a sustainable and reliable source of clean energy. The use of solar panels on military bases not only helps to reduce carbon emissions but also enhances the resiliency and security of the base's energy infrastructure.
- Q: What is the typical warranty period for solar panels?
- The typical warranty period for solar panels is around 25 years.
- Q: Can solar panels be used in multi-story buildings?
- Yes, solar panels can be used in multi-story buildings. They can be installed on the rooftops or facades of these buildings to harness solar energy and generate electricity. Additionally, advancements in solar panel technology have made it possible to integrate them into building materials, such as windows or cladding, allowing for even more flexibility in their use in multi-story structures.
- Q: Can solar panels be used in areas with limited space?
- Yes, solar panels can be used in areas with limited space. There are various options available, such as rooftop solar panels, solar canopies, or even solar panels integrated into building materials. These solutions are designed to maximize the utilization of limited space while still harnessing solar energy efficiently.
