 FAQ of Polycrystalline Silicon Solar Panel Type CR290P-CR250P

(1) Can you offer the test report of the module?

     Sure. All the solar modules must pass necessary tests including EL test and ultra-red test and other visual test of the apperance, and the test report presents all the detailed data of the modules.

(2) How  to confirm about the quantity and the type of solar module?

     It depends on the solar system where  you want to put into use the solar modules. We have experienced engineers to design for your order and you need to give more information to fix the details.

 



Solar panel working process

In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.

The basic unit of a solar panel is a solar cell, which usually consists of one or two layers of silicon-based semiconductor wafers. When struck by the photons in sunlight, the solar cell generates an electrical charge due to the "photovoltaic effect" – which is a pretty good name, since it produces voltage from photons. The flow of these electrons moves in a steady electrical current from one side of the cell to the other.




Q:Can solar panels be installed on greenhouses?
Yes, solar panels can be installed on greenhouses. In fact, it is a popular practice as it allows for the generation of renewable energy while utilizing the available space on the greenhouse roof. The solar panels can help offset the energy needs of the greenhouse and contribute to a more sustainable and environmentally-friendly operation.
Q:Can solar panels be used to power a construction site?
Yes, solar panels can be used to power a construction site. They can provide a sustainable and renewable source of energy, reducing the need for traditional fuel-based generators and minimizing carbon emissions. Solar panels can be installed on rooftops or on portable structures, providing electricity to power tools, lighting, and other equipment required on a construction site. Additionally, excess energy generated by solar panels can be stored in batteries for use during non-sunlight hours, ensuring continuous power supply.
Q:Okay, so I have a science fair coming up soon and I need help with my project. SO - What should I use to demonstrate with the propeller? A toy boat? Plane? And I only have mini solar panels ; so how do I put the solar panels on the toy boat/plane to make the propeller move off of the sun's energy? Thanks. Steps please!
Solar panels produce electricity. To move the propeller you need mechanical motion. An Electric motor converts from electrical to mechanical power. Most Solar Panels produce DC electricity as do batteries so you need a DC motor that is sized to match the Output of your solar panels. For small temporary projects like this I find that hot melt glue is great to assemble parts. Using a voltage meter you can expose your solar panels to a strong light (or one equal to what you expect during your demonstration) and measure the voltage across the terminals. This may help to size the motor. It depends upon the size of your propeller and how it is made. Your three choices are to use it to power an airplane, to power a boat underwater or to power a boat like an air boat. You might also use the air boat concept to make a car. (air car) The air boat might be the simplest to make but you will need a body of water to demonstrate the concept. The air car doesn't have such a requirement.
Q:How do solar panels affect the overall carbon footprint of a building?
Solar panels can significantly reduce the overall carbon footprint of a building. By harnessing the power of the sun to generate electricity, solar panels reduce the reliance on fossil fuels for energy production. This means that less greenhouse gases, such as carbon dioxide, are released into the atmosphere during the building's operation. Consequently, solar panels contribute to a cleaner and more sustainable energy system, helping to mitigate climate change and reduce the building's environmental impact.
Q:Can solar panels be used on commercial buildings?
Yes, solar panels can be used on commercial buildings. In fact, many businesses are embracing solar energy to reduce their carbon footprint and save on electricity costs. Installing solar panels on commercial buildings not only helps generate clean and renewable energy but also provides long-term financial benefits for businesses.
Q:I have:4- 5v 200ma solar panels5- 3v ,000ma solar panels- 7amp charge controller- 400watt inverterNow I have all my solar panels linked in series which in theory should give me 35v, 5.8 amps at 203 watts. Is this correct?The main question is, what kind of battery should I get so I can run my miscellaneous electronics off of it?I may not have explained it so well so if you need more information, feel free to ask.
I okorder and they have deep cycle batteries exclusively made for solar panels. but in theory you should get more than one because it only takes around 4-5 volts to charge the battery and you do not want to have it that high even with a charge controller which i would also recommend getting which is like $50 on OKorder but a charge controller is used so you do not overcharge the batteries and fry them or undercharge the batteries and weaken its life it gets it just perfect. it lets the current go in and when it is charged fully nothing goes in an nothing comes out.... for a inverter the one i was going to get was $70 500 watt inverter but changes it from dc to ac...hope i helped
Q:okay so my teacher is trying to install a solar panel but we have a problem we don't know where to ground it because it will be a movil house. guys do you have any ideas?
Typically you mount it with the frame as a ground and you ground the frame with a wire or cable tied into the ground when the mobile home is parked.
Q:Photosynthesis is fairly inefficient, but efficient enough to power all life on earth.
Si is a neutral semiconductor, and, when combined with the other metals in the solar panel, it the panel polarizes, and releases electrons form one end, and accepts them back at the other. Like a water pump. Mg is not the major ingredient because it doesn't have the easily altered semiconductor properties Si does. To put it simply, Si is easier to work with.
Q:For those solar panels that you install on your rooftops, do they generate electricity when it's cloudy? And if yes, how much electricity does it generate compared to sunny days? For example...like only 25% electricity generated compared to sunny days?
No, silicon photovoltaics reacts to a very specific frequency of infrared light which matches the bandgap energy of it's outer electron shell. This frequency is reflected by clouds. However, thermal solar collectors such as evacuated tube collectors can function under cloudy skies albeit at a lower rate and there is at least one hybrid photovoltaic and thermal panel designed to take advantage of this.
Q:Heard you can put solar panels on laptops Anyone know if it can work on a Dell mini 0v? I've seen he USB slot solar pana but can someone tell me where to gt these?
That strikes me as completely impractical for most circumstances. The power output of your mains adapter is 30W and to do that you are looking at at least five or six square feet of solar panels costing in the region of $600 even from a surplus supplier I know. You could do it cheaper (maybe $50 on panels) but then you would be looking a more primitive panels and need perhaps thirty square feet of solar panels. This is a completely different exercise to creating a solar powered USB charger - the power requirement is a lot higher. Astronomy and space?
