Product Description:

Solar panel material

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:Are solar panels only effective in places where there is an abundance of sunlight?
Solar panels generate power only during sunshine hours. But they only need sunshine, they don't like the heat, that comes along with the sunshine. So its a trade off, the places that have a lot of sun, also have a lot of heat, and places that do not have a lot of sun are not that hot. But you do need sunlight to run solar panels. There's a lot of tools available which can tell you how much power you are able to generate given your location.
Q:Does It really cost that much to Install solar panels?
Are they saying that the panels cost $5k and the installation cost $35k? Or are they saying the panels were $50k, plus another $35k for installation, making the total $85k? Possibly the data was from several years ago. $5k buys 6 kW of panels today, larger than goes on most houses. Installation depends on local labor costs, but should not be more than about $5k in the US, unless the system is huge, or unusual, such as a standalone system on a concrete pad, instead of just on the roof. The system on our roof is roughly 3 kilowatts. If installed today, the parts would cost about $9k. After federal tax credit, $7k. Labor depends on the local situation. We installed our own, so didn't pay any labor cost.
Q:How can I be part of the solar panel industry?
Manufacturing your own electrical solar panels is out of the question. They are built much like computer chips and setting up a plant to do this would cost millions of dollars. You could become a solar system installer. These businesses install solar systems on homes and are paid for this service. You will need a significant amount of technical training to do this though, I would guess at least two years (the last thing you would want to do is damage someones home or design a system that is dangerous). I would suggest that you go into business making energy improvements to homes that do not involve solar energy. Most people can get the best value for their money by improving the air tightness of their homes (several tubes of well placed caulk). Other things you could offer would be the upgrading of door, Windows and electrical box seals. Insulation jackets around hot water heaters is also something a small firm could offer home owners. Other energy improvement are also possible and you could offer a whole shopping list of improvements to a customer. Good luck
Q:How efficient are solar panels?
Q:how effective & efficient are home made solar panels?
I had a system installed recently, so I would suggest starting by getting a quote from a licensed contractor. Even if you are planning on doing the installation yourself, a contractor will have a lot of useful info. I got 3 quotes and they were all about the same cost. I was able to get a 2 year usage history from our utility so the contractors were able to suggest a system based on that. They were able to tell me about rebates and tax credits, were the best location would be and the estimated amount of production. They have a nifty gadget that can tell if there will be any shade cast on the roof at any time during the year. I decided to maximize my rebates and got a system that reduced my utility bill by about 50%, although my production has cut it much more than that, my highest electric bill was $35, and that was in Dec. with cloudy short days. I got a $0K rebate and a $2K tax credit. This year the fed. tax credit is 30% of the total installed price. My system cost $26K, I paid $6K out of pocket and I'm saving about $2K per year.
Q:Solar panel help please?
Q:Pls is it ok to connect a 0watt and 20watt solar panel together into a charge controller port?
Tobi, generally yes, solar panels are like beer, all the europeans get along fine, you can put two Belgiums in the same room as one German and three Englishman. As long as the panels have roughly the same open circuit voltage, usually around 8 volts, then go for it. If you're not sure about this, or the panels voltage disagrees dramatically, then they can still work through the same charge controller, the only other thing you need is a bypass diode in the junction box on the back of each panel. Most modern panels come with these already installed. They are simply electrical check valves, allowing current flow in one direction but not the other. The reason these matter is when the sun is first coming up, the higher voltage panel can force its power backwards through the lower voltage panel, at least until they both reach a voltage higher than the charge controller is set at. This is not a desirable thing to have happen, the 20 watt panel, if its voltage is higher, can damage the 0 watt panel without these diodes if the 20 watt has a much higher open circuit voltage, or Vmax. Look on the back of the panel for these ratings. The only other concern is maximum current. A charge controller has a maximum current it can handle, they are generally model numbered this way, a Xantrex C-60 for example has a 60 amp rating. Add up the Imax numbers on the back of all your panels, this is the maximum amperage the panel should put out. As long as it is not above 80% of your charger controllers maximum amperage, your good. Take care, Rudydoo
Q:Can you overload solar panels with too much light?
yeah, as you shine light over a solar panel, it begins to lose electrons to the circuit. if you shine light with enough intensity (that means not strong light, the photoelectric effect makes no distinction between a powerful photon and a weak one, as long as they're both over a certain energy, but a lot of it, as in, a lot of photons), the material may not recover electrons at the same rate it loses it, and would stop working, until you gave it a rest.
Q:Improvising Solar Panel Made from Old CD or DVD? Possible or not?
A solar electric panel? No. Solar electric cells, or more properly photovoltiac (PV) cells, are made from specially prepared (doped) wafers of silicon, much like transistors and diodes. CDs and DVDs are made from plastic plated with aluminum. They don't have anything to do with each other. Of course you can make a reflector out of CDs or DVDs, and you could use a bunch of them to focus sunlight on a water tank or something - this is called solar thermal generation. (That's what that ehow page is talking about, not generating electricity.) But there are much better things to use for mirrors.
Q:Solar Panels for Jacuzzi?
You can do this by isolating the jacuzzi, you will need a solar array adequate for the power draw of the jacuzzi, a charge controller, battery bank, off-grid inverter and switch gear. This is the expensive way to go--especially if you are planning to heat the water with the solar. A better option would be to heat the jacuzzi with solar thermal panels. It is plumbing instead of electrical, but the cost would be much less. If you still want to do PV (electric) solar, think about putting a non-isolated grid-tie solar array on your home. They are much cheaper, and if you think about it, it really does not matter if you use the solar electricity to run a light, a fridge, a TV, or a Jacuzzi, that amount of power is subtracted from your overall house power bill. Just size the array for the power output of the jacuzzi, and let the power meter do the rest. Your overall result will be the same and the system will be half the price, or less.
