· Characteristics of Polycrystalline Silicon Solar Panel
I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.
II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.
III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.
IV AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.
V Junction box: Multi function junction box with water proof.
VI Long lifetime: ≥25 years; Less power decrease.
VII Good performance of preventing from atrocious weather such as wind and hails.
VIII Resisting moisture and etching effectively, not effected by geology.
IX The certificate issued by international authority: UL, TUV, IEC, VDE, CE.
- Q:I know that one LED can't power a solar panel. I have found 40 kmcd LED's on OKorder. I know that several of them (28 totale each one with a 470 ohm resistor all at 2 VDC) can show a reflection on a wall in daylight 60 feet away..

- Q:Can solar panels be installed on a boat or RV?
- Yes, solar panels can be installed on both boats and RVs. In fact, they are a popular and efficient option for generating electricity in these mobile settings. Solar panels can provide a sustainable and renewable energy source, reducing the reliance on traditional power sources while providing power for various appliances and systems on board.
- 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?
- The most important thing is for how much time the sun shines at your place. If you are living at a place where the sun shines just for to 2 hours then installing a solar panel will be of no use. But if sun shines at least 9-0 hours then solar panels will be in use.
- Q:Can solar panels be used in areas with high levels of air humidity or moisture?
- Yes, solar panels can be used in areas with high levels of air humidity or moisture. While excessive moisture may slightly reduce the efficiency of solar panels, modern panels are designed to withstand a variety of weather conditions, including high humidity. Furthermore, regular maintenance and cleaning can help mitigate any potential impacts on performance.
- Q:ok so when a solar panel is marked as a certain wattage dose that mean it makes that much in a day in an hour or constant, dose it still work at night or what ? is it worth it or is it more of a pain? can some one tell me what all the watts and volts mean ?? and can some one tell me what a kilowhat is in refrence to some thing i understand like howmany loads of laundey can you do wt a watt? i need help understanding this stuff?

- Q:I am building a solar car for the energy wiz competition and I was wondering how I could possibly get my solar panel to shift sideways
- having solar panels move like that on a mobile platform is inadvisable -- especially if there is a dynamic wind load resulting from the motion of the mobile platform. Even having a tilt mechanism is dubious at best. think of what limited marginal gain would be gained by mounting a small solar panel on the moon roof of a car. (ultimately, the best answer is to turn the car so that it's angle to the sun is optimal -- but the road/travel direction constraints are what ultimately prohibit that.) while there are ways to build sliding panels, the weight constraints would interfere with your weight/thrust ratios to the point of futility. if you really need that panel somewhere else, don't slide it out of the way, just buy another panel and mount it there. it's more expensive, but it's actually the cheapest solution in terms of design on a mobile platform.
- Q:lately i have been interested in solar power. i own my own home and in Texas it's HOT, so my A/C is always on and that light bill is like $300.00 a month. i was looking at other light companies but then i remembered that there are the so called solar power but i dont knowknow to start or how it would work to power the a/c machine...pls help
- I live near a community in Mexico where hey have no power. It is in the desert and is perfect for solar because they only have 3-4 in. rain a year. It is on the beach so many wealthy have homes there that are on solar systems. I have helped my friends set up and work on many of them. Solar systems WILL NOT normally support air conditioning unless you install a gas powered ammonia or lithium Bromide system. In these systems the refrigeration cycle heat is supplied by the gas instead of a compressor, so the only electrical power is a small circulation pump which will not drain batteries fast. These are a problem in some areas because not many people know how to maintain and repair this type of system. Some of my friends claim they can run a very small one room AC on their solar systems just to at least have a place to sleep that is cool. Others say it is questionable. Please understand these systems are not cheap. Most of them paid $20,000 - $35,000 and even more if you use the ammonia cycle AC. The systems usually have 0-2 panels, a 0-5 KW gas generator, and large bank of large batteries like ones you use in a golf cart or bigger. I also must apologize to all the environmentalists for the inconvenient truth.
- Q:If i took a lazier pointer and aimed it a solar panel would it take in the light. Also what types of lights would work on a solar panel like L.E.D, uv light bulbs.
- lazier ? Do you mean laser? Solar panels are made to respond to all visible wavelengths as well as IR frequencies. So yes, it will respond to a laser, if the beam were not too bright. Too concentrated a beam could burn out the cell.
- Q:Can solar panels be used for powering public transportation?
- Yes, solar panels can be used for powering public transportation. Solar energy can be harnessed through solar panels and converted into electricity, which can then be used to power electric buses, trains, trams, and other forms of public transportation. This helps reduce dependence on fossil fuels, lower greenhouse gas emissions, and promote sustainable and clean energy solutions for transportation systems.
