1. glass

 Its main role is to protect the power generation ( solar cells ) , there is a selection of light transmittance requirements : 1 ) must be high transmittance (typically 91% or more ) ; 2 ) super white steel processing.


2. EVA

 For bonding glass and power generation fixed body ( such as cells ) , transparent EVA material directly affect the life of components exposed to the air EVA prone aging yellow , thus affecting the transmittance components , thus affecting in addition to generating the quality of the components itself, the quality EVA lamination process on the component manufacturers is also very large, such as EVA plastic viscosity of non-compliance , EVA and glass, back bonding strength is not enough, can cause premature aging EVA, the affected component life.


3. Solar cells

 The main role is to generate electricity , the electricity is the main market mainstream film crystalline silicon solar cells , thin-film solar cells , both have their advantages and disadvantages . Crystalline silicon solar cells , the equipment costs are relatively low , but the high cost of consumption and cells , photoelectric conversion efficiency is high, the next generation in outdoor sunlight is more appropriate ; higher thin-film solar cells , the relative cost of equipment , but the cost of consumption and battery low, relatively low photoelectric conversion efficiency of crystalline silicon solar cells , but the effect is very good low-light , in the ordinary light can also generate electricity , such as solar calculator .


4. backplane

 Sealing, insulation , water ( usually with TPT, TPE , etc. ) the material must be resistant to aging , component manufacturers generally have warranty for 25 years , tempered glass, aluminum is generally no problem , the key lies in whether the backplane and can meet the requirements of silica gel.

Q:what do we mean by efficiency of a solar panel?
Photo-voltaic solar cells use the visible light range (photons) for the conversion of sun's rays to electrical energy. The potential of solar radiation is ,353 Watts per square meter, but that is mostly a measure of heat, or infrared radiation. The visible light is actually a small portion of the spectrum. You have struck on a problem associated with photo-voltaic cells. Infrared radiation acts to heat up p-v cells (heat stress), causing them to be much less efficient. It would be interesting to see a hybrid p-v panel that is cooled with fluid or air running through it. This would increase efficiency of the p-v process while providing a heating source. This in turn could be used directly for heating or for production of electricity through a generator system.
Q:What solar panels are the most efficient?
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:How do you use solar panels?
Custom solar-heating systems are unique. Does yours have a circulating pump? Does it have a storage tank? Is the fluid that goes to the panels separated from the household water and transfers heat through a heat-exchanger radiator, and the fluid has antifreeze in it? If it does, is the antifreeze of the variety that won't poison your family if there is a leak? Does your system have a thermostat-controlled pump that turns on when the water in the panels are hot? Does it have a limit-thermostat to turn off the pump when water in the storage tank is hot? There are many more variations to operation of solar-heating panels. Find out who designed it or who knows how to operate it and ask them.
Q:help setting up a solar panel system?
ever looked at the light from a 45 watt bulb? it's true that in a cabin, if you're in the right place, you can read from it. however, assuming that you get 6 hours of sun, you can run your light for 4-5 hours. and nothing else. if you're hoping to run a stove, you're going to need several hundred watts. not sure what tools you're thinking of, but i don't know of many that run on 2v DC. (not sure that i know of a stove that runs on 2v DC either, but you can look that up.) for tools, you might want to consider a gas powered compressor and air tools. that'll give you the strength that you need. yes, i know that's not what you were thinking, but pretty obviously you're going to need to do a bit more thinking. even a minifrig is going to use considerably more than 45 watts. and that would be 24 hours a day. remember, a minifrig has considerably less insulation. you can't save much and per pound, it takes more juice.
Q:What is the principle and structure of solar panels?
solar panels: solar panels is the core of solar power generation system, solar power system is the highest value of the part. Its role is to convert the sun's radiation capacity into electricity, or sent to the battery to store, or to promote the load work.
Q:How can I power 5v or .08 amps in a remote loaction via solar panel.?
First things first. 5 Volts @ .08 amps would be .2 Watts. therefore you would need at least the same amount from a solar panel to replenish the batteries. But what puzzles me is the notion that plugging it in a wall outlet ? If you use 20 V @ 0.08 then the power consumption is 9.6 Watts And what is a meraki wireless repeater? I never heard of one. I'm a FCC licensed Ham and have some idea what is available. If you need 5 volts DC, you could use twelve Ni-cads in series and just keep them trickle charged with the solar panel That would make it compact. If you were to use an automotive battery (or motorcycle), then you would need a DC/DC converter.
Q:Solar panels?? I need 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:Will a 3w Solar Panel Charge A 55ah Car Battery?
To charge a 2V lead acid battery, you pretty much have to put almost 24V across it and it's only 50% efficient at charging so if your solar panel does put out 3W, you can expect 3/24/2 or /6th of an amp in usable charging. Therefore, from a flat battery, it would take 55*6 or 880 hours to charge the battery. If you assume about 6 hours of usable sunlight per day, that would be 47 days not taking into consideration the normal leakage that lead acid batteries have. It's quite likely that the leakage rate will be greater than the charging rate and the battery will never charge. You'll need a bigger solar panel.
Q:What are the properties of Solar Panels?
Solar power Power Can Help Preserve You Money The cost of power is going up, and will only keep going up. Reaction Solar power Power Systems will help you save a large number of kWh each season by utilizing screen technology. Power created by your program are kilowatts you don't need to pay for! Every electricity program will make a number of Small-scale Technology Accreditations (STCs) upon purchase based on the size of the program and the location where it will be set up. These STCs have a market value and can be exchanged and marketed just like stocks. Power created by your solar PV program can be marketed to the lines for a top quality cost via Feed-in charges. These feed-in charges are different in every state, but the primary idea is te same, to compensate entrepreneurs of small-scale power creation. You are eligible to sell some or all of the ability you produce for more than you would normally pay for it. Would you like to decrease costs with solar power? Contact Reaction and get it done these days. Solar Power Can Help Preserve The Environment click to enlarge Producing usable direct sunlight generates no dangerous pollutants. Every season coal-fired power vegetation belch a large number of loads of as well as contamination into the weather so we can run our refigerators, toaster ovens, and have hot bathrooms. Taking your power form your own ceiling means you are no longer leading to that contamination. In fact, power companies will be paying you for electricity! Help Sydney accomplish its 5% green energy focus on by 2020 and international objectives of 20%, by changing to solar power and decreasing your own effect on international warming. Compared with other small-scale turbines, solar power is completely quiet. Turn the team radiation into power without making a audio and decrease environmental disturbance.
Q:Solar Panel, what is the catch ?
using solar panel in your life, you can save the electricity bill, also you are saving energy for our later generations. If more and more people are using solar energy, the mother earth will become more beautiful.
