FAQ

 

Q1: How to choose a right inverter?

A1:Tell us your demand, then our sales will recommend a suitable inverter to you.

Q2: What's the different between inverter and solar inverter?

A2:  Inverter is only accept AC input, but solar inverter not only accept AC input but also can connect with solar panel to accept PV input, it more save power.  

Q3: How about the delivery time?

A3:  7 days for sample; 25 days for bulk order.

 

 

 


Q: What is the principle of solar panels to convert solar energy into electricity?
When the light is irradiated on the surface of the solar cell, a part of the photon is absorbed by the silicon material; the energy of the photon is transferred to the silicon atom, so that the electrons are moved and the free electrons are formed on both sides of the P-N junction to form a potential difference. When the circuit is used, the current will flow through the external circuit to produce a certain output power. The essence of this process is the process of converting the energy of the photon into electrical energy.
Q: Can solar panels be installed on a sloped roof?
Yes, solar panels can be installed on a sloped roof. In fact, sloped roofs are quite common for solar panel installations. The angle and direction of the slope can affect the efficiency of the panels, so it is important to consider the roof's orientation and shading when planning the installation.
Q: I want to make 2V 4.5A solar panel to charge my battery used in my RC car project. I just like to know how should I amplify the current for 4.5A. I need the total circuit diagram. Can anyone help me. Please. I need some affordable methods please.
The simplest way to use these panels is simply to connect the panel to your battery, with a diode in series to prevent the battery from discharging through the panel (no sunlight condition). Just connect the battery for the required charge time then disconnect it. Full sun is required, no shadows on the solar panel! ---------- .
Q: Can solar panels be used in off-grid systems?
Yes, solar panels can be used in off-grid systems. Off-grid systems are independent from the main electrical grid, and solar panels are a popular choice to generate electricity in such systems. They capture sunlight and convert it into usable electricity, which can then be stored in batteries for use when sunlight is not available. This allows off-grid systems to meet their energy needs without relying on traditional power sources.
Q: i'm making a small solar panel powered fan but it cant run the cellphone vibration motor even i have place two x2 solar panel.
A solar cell's purpose is to generate electricity through the release of electrons from a material that is bombarded by electromagnetic radiation or photons. Most crystalline solar cells are sensitive to visible radiation from 400 - 700 nanometers, which correspond to 3. - .8 electron volts, of the visible region as shown by ACEPT W3 Group (999) and also into the near infrared spectrum. As the wavelength of the electromagnetic radiation increases, the amount of electron volts decreases. This means that infrared radiation has less electron volts than the visible spectrum of light (because it has a larger wavelength than visible light) and ultraviolet and gamma radiation has more electron volts than both the visible spectrum of light and infrared radiation (because they have a smaller wavelength than both infrared and visible light). Abramowitz, M., Davidson, M., Neaves, S. (2003) wrote that all forms of electromagnetic radiation originate from the atom which contain orbiting electrons around its nucleus. When those electrons absorb more external energy than they can contain in order to be stable, the extra energy is released in the form of an electromagnetic wave. That electromagnetic wave contains a magnetic field and an electric field, one offset by ninety degrees to the other along the propagation plane.
Q: Why should I have a Generator if I have Solar Panels.....?
Well the sun don't shine at night does it. Nor much on cloudy days. You either need a generator or a whole lot of batteries. The batteries are a pain to maintain, they're expensive to install and they have to be replaced periodically. Generator's probably a decent alternative. I'm sure most people just stay on the grid for their backup. Even better if you live in an area where you're allowed to sell back excess capacity. If you're looking to spend this kind of money anyway you could look at a household fuel cell that runs on natural gas. Awesome technology, though if you buy the unit all prebuilt and ready to go it's going to run you like 50,000 bucks.
Q: Can solar panels be used in areas with high levels of shade or obstruction?
Solar panels can still be used in areas with high levels of shade or obstruction, but their efficiency and power generation may be significantly reduced. Shadows or obstructions can cause partial or complete shading on the panels, which can lead to a decrease in energy production. However, advancements in technology, such as the use of microinverters or power optimizers, can help mitigate the impact of shading by allowing each panel to work independently and optimize energy production. Additionally, proper placement and angle adjustments of the panels can also help maximize sunlight absorption, even in shaded areas.
Q: How can solar panels be used for heating water?
Solar panels can be used for heating water by using the energy from the sun to heat up a fluid, typically water or antifreeze, which then transfers the heat to a storage tank. This heated water can be used for various purposes such as showers, washing dishes, or heating indoor spaces.
Q: I don't remember what number exactly but it's in the single digits. This number represents how efficient solar panels are at capturing the sun's rays and converting it into electricity.Why?
There are a lot of solar panels available today's. The problem of the efficiency is the proccess of converting, these cells use the photons of the sun to react with the ( Si compound inside the cell) due to the little thing that cell's are only a fraction of these energy is converted, remember that solar cells are paper thin and the really problem of these cells are the voltage not the amps. A single 3x6 inches solar cells can produce 3.6 amps but only 0.5 volts.
Q: Ok, so my homework was to research and write about how solar panels and solar furnaces work and about their construction. We didn't even take one lesson on it in class and we are not allowed to copy and paste much and have to keep it simple wtf? Its soo annoying as we have hardly took it in class. Please can someone help.
Well solar panels conduct electricity from the suns waves and turns it into dc current then it is either put into a grid tie inverter to change it to AC and it makes you meter go backwards instead of forwards. or if its not a grid tie inverter it is just put into batteries as dc then changed into AC from the inverter and then used for household appliances. nothing really does run on DC that is why it has to be changed. and for solar furnaces if you mean a water heater that works by a substance here in Pa its antifreeze is heated up by the sun in the panel it is in a continous loop and that is what gets heated up the water then flows over tow of the tube that contains what ever substance such as antifreeze and heats the water.were the water and the tube that changes the water from cold to hot is called the heat exchanger. the substance is actually get heated first then the water. solar heating for water accounts for 29% of water heating in the us. Now if you mean solar furnace as in passive solar thats completely different because here in Pa if we want it our houses have to face to south to get the suns rays. (alot more windows) and there is a cement slab placed only on the south side of the house and it has insulation covering it. There is a certain type of glass that is used for this that will allow the suns rays to come in and let the heat in for the summer and also for the winter. the main place for that would mostly be the first floor of the house due to the height of the windows and the angle of the sun(pa in the summer is 73 degrees and in the winter its 27 degrees) thats when the second floor would be ok to heat the rooms. Hopefully i helped and i explained it in a way that you can understand.
