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:

（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: 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: I'm curious, for those who have had solar panels installed on the rooves of their houses:How much did you pay? How much energy do the panels produce? Did it dramatically cut down on your electricity bill? Was it worth it? Thanks!: No, but if you have the money, go for it. In Germany, people get a government rebate (much like the Prius rebate our own government offered) and so you see solar panels everywhere. If the Obama administration pushes for a rebate for solar panels, you will see them here in the state. It's the initial cost that puts off most potential solar panel customers. Upkeep isn't too expensive, and they ultimatley pay for themselves. (after about a decade)

Q: please no dumb answers and list where you got the info.Also how much does it cost to install solar panels for a regular sized house?: Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .

Q: Can solar panels be used in cloudy regions?: Yes, solar panels can still be used in cloudy regions. While they work most efficiently under direct sunlight, they can still generate electricity even on cloudy days.

Q: I have an inverter and a battery 20 Amperes.Daily sun shine approx. 7 Hours.Do I need to buy anything or should I connect the solar panel to the Battery direct?: No, don't connect the panel directly to the battery. You need to isolate the solar panel charging output from the AC-powered charger. A couple of high-current diodes arranged with their anodes connected to the charging sources in the positive supply line will allow either the charger or the solar panel to lift the voltage high enough to charge the battery, albeit with about 0.6 volts dropped across the diode. Both cathode ends would be connected to the battery. This arrangement allows a positive current to flow from either or both charging sources at the same time, although in practice, one will generally be higher than the other. Also, if the AC charger's voltage is significantly higher than the solar panel, the charger may always charge the battery. You would need to regulate its output to be slightly lower than the solar panel when it's near it's minimum useful operating voltage. (note that the 0.6 forward bias voltage on the diode might prevent the solar panel from completely charging the battery if it has any voltage regulation on its output)

Q: Can solar panels be used in areas with high temperatures?: Yes, solar panels can be used in areas with high temperatures. In fact, solar panels are designed to withstand a wide range of temperatures, including high heat. However, it is important to note that excessive heat can slightly reduce the efficiency of solar panels. Therefore, proper installation and regular maintenance are crucial to ensure optimal performance in hot climates.

Q: how big of an solar panel do i need to power/charge my laptop?would one from canadian tire sell the right one?: Most decent laptops can use 50W of power or more....so you'd actually need a large solar panel with good sunlight. I just looked up how big a 50W solar panel is....it's about 64x64 centimeters...which is very big and expensive! So, solar power may not be the best solution to power, or charge a laptop battery. Maybe there are some solar powered chargers that charge the battery very slowly, but probably not.

Q: Can solar panels be used to power a restaurant?: Yes, solar panels can be used to power a restaurant. Solar panels generate electricity by capturing sunlight and converting it into usable energy. This energy can be used to power various appliances, lighting, heating, and cooling systems in a restaurant. By installing solar panels, restaurants can reduce their reliance on traditional energy sources and lower their electricity bills while also contributing to a more sustainable and eco-friendly operation.

Q: Can solar panels be installed on museums or cultural centers?: Yes, solar panels can be installed on museums or cultural centers. In fact, many museums and cultural centers are embracing solar energy as a sustainable and cost-effective solution for their energy needs. By installing solar panels, these institutions can reduce their carbon footprint, lower energy costs, and demonstrate their commitment to environmental stewardship. Additionally, the installation of solar panels on such iconic buildings can serve as a visual representation of their dedication to renewable energy, inspiring others to follow suit.
