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.
Specification of Solar Monocrystalline Series
- Optimal permutation on solar cells to keep enough heat diffusion, decreases hot spot effect.
- High quality and anti-ageing EVA, weather resistance backside raw materials assure reliable solar panels.
- Passed 5400Pa mechanical loads testing by UL, can withstand bad and high mechanical load working environment.
- With good sealed performance, moisture resistant, aging resistance, high/low temperature resistant, the inner terminals of our junction box owns good electrical performance transmission. Bypass diodes used can avoide hot spot effect and damages to panels. Output cables and mating connectors are safe and reliable for installation application. Adopt weather resistance, sealed, good sticky silica gel when assembling.
- Strict quality inspection on each procedure and 100% electrical performance test to meet power requirements.
- 0~+3% power tolerance.
- classification for all the panels in order to improve the integral performance of system and solar panel life span.
- TUV、UL、MCS、CE、ROHS、Golden Sun certified
- Underwriting of 25years output power warranty by The People's Insurance Company of China.
- Q: what is a solar panel?
- a electronic collection grid that turns solar energy into electric power
- Q: I want to build solar panels for my house.Dose anyone try okorder is this really work?
- Build okorder
- Q: Ok so i have to solar panels to charge a battery however the panels hooked up in series does charge the battery very slowly because series connections only multiplies the voltage but leaves the current the same. Is there a way i can also hook both of them up in parallel at the same time to multiply the current for faster charge? I know i can do this with 4 panels but i dont want to spend extra. So is there a way to hook up 2 solar panels in series and parallel at the same time? Thanks in advace
- never hook up solar panels in series, you reduce the total power produced, and may hurt them, only voltage out, never voltage in. Don't forget to vote for best answer!
- Q: My project needs to build a thermal solar panel that would be used as a demonstrational rig. The dimensions i am allowed do not allow me to use a normal thermal solar panel so i have decided to use the heat exchanger from the back of a fridge. Although this is possible to use what equation would i use to prove the power of the sun would actually heat up the water. More importantly when the rig is demonstrated to students, they will need to be able to determine if the raise in temperature given by the thermometers is what should be given. Variables of the rig will include: Angle of the panel, Light intensity, Direction of panel, and more importantly the flow rate of the water travelling through the pipes. What equation includes those variables (change in temperature, flow rate) and would allow me to incorporate the angle of the panel. The light source would be a lamp so i would also need to know how much of the energy from the lamp is actually being used by the panel?
- Forget the long winded discussion above. There are so many variables that you cannot calculate the outcome. This does not mean that the experiment is a failure. It gives you information on the fact that water can be heated in this manner, and that you can vary the result by modifying the variables.
- Q: I have a home made 24 volt electric cart. It is powered by two 2Volt deep cycle batteries. Since the motor runs on 24 volts the batteries are wired in series to produce the 24 volts. I only have a 2 volt battery charger, but I also have two 2 volt solar panels. It is a pain having to unhook wires, rewire it, or charge them one at the time.HERE IS THE QUESTION REALLY... Can I wire the two 2 volt solar panels together in series (ie: negative to positive) then connect it to the existing 24 volt system and have it charge the batteries fine. I know basic wiring, but I know nearly nothing about solar panels, will it work fine? will it cause them to break? or short out?(additional info, the solar panels are only rated at 5 amps so it will not overcharge the batteries or anything)
- You should be fine with the series as long as you use a multimeter and verify configuration Get a charge controller. Will be worth the small cost and prevent many issues.
- Q: Can solar panels be installed on electric fences?
- Yes, solar panels can be installed on electric fences. The panels can provide the necessary power to keep the electric fence operational without relying on traditional electrical sources.
- Q: I recently bought a house with very old solar panels (about 25 years old) that don't appear to work properly. They are supposed to heat the hot water heater but they don't always work, and recently have staretd leaking. So, I have had them turned off and now we're just using electricity to heat the hot water. My question is, is there any tax credit money (stimulus or otherwise) available for people to (a) repair old solar panels or (b) replace them with new ones? How does the credit work?
- Congratulations okorder /
- Q: I was thinking of having some installed on our rooftop and was wondering if it would be worth the cost? The house is located in Sac, Cali. The panels would face the sun 2 months out of the year and in the summer roughly 4 hours of straight sun.
- You can log in alibaba,i purchased about 20000watts 2 years ago and solar panels work efficiency is fairly high. I hope my answer help you !
- Q: Can solar panels be installed on a museum or cultural institution?
- Yes, solar panels can be installed on a museum or cultural institution. Many museums and cultural institutions have embraced solar energy as a sustainable and environmentally-friendly solution for their energy needs. Installing solar panels not only helps reduce their carbon footprint but also saves on electricity costs in the long run.
- Q: Could you have a solar panel in space that would transmit electricity remotely? Maybe have some kind of receiving antenna to pick up the energy? Perhaps there could be a string of them orbiting the Earth?Why wouldn't that work?
- Amazing how antique technology is so easily forgotten. Nikola Tesla first introduced the idea of wireless energy transmission in 89 and proved it by 899 in Colorado Springs, CO. He proved the Earth itself was a conductor of electricity. He also successfully conducted long-distance wireless energy transmission and reception. He wrote about the ability to wirelessly send electricity from a few central sources using longitudinal waves and magnetic flux all around the globe to be received at any point therefore electricity could be accepted by all uniformly. Although the means by which to do it was extremely far fetched, his theories are solid.
