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:I'm thinking of these solar panels that people have on their rooftops in domestic properties. I suppose I mean after how long do you break even with respect to just carrying on without them and getting you electricity from the utilities companies? Or answer in any way you think is pertinent. The more info the better.
Hi Warne, Payback period of solar panels depends on three main factors: ) Amount of solar radiation available: the more solar resource available at a site, the shorter the payback period will be. The insolation level is a function of latitude, cloudiness, elevation and some other factors. 2) Availability of grants, incentives and tax credits. Reducing the initial cash outlay is a great way to speed up profitability. For example, in the US, the 30% federal tax credit greatly reduces the payback period as it puts some of the cash back in your pocket in a short amount of time. Minimizing the initial cost has a big impact, since money in your pocket today is always worth more than money down the road. 3) Net metering or feed-in-tariff. If you are able to sell back your excess power, or all of the solar electricity to the grid, then you can also improve the payback period. Feed-in-tariffs are not very common in North America, but net metering is an option. Investing in energy efficiency measures (e.g., LED lights) at the same time as solar may help generate more excess power and help with the bottom line. There are some online calculators which may help you put all these together for a specific site. I'm including a link below.
Q:Hi, I want to put some solar light in my yard, and wondering if a 00w solar panel could work for a few 3w dc lights....do i need a battery so they run at night, if so how many lights do u think i can run/ also i see elading solar light
No longer just any bulb will work on DC power. Any light bulb that's for 0voltage won't work on DC energy due to the fact that the element has too much resistance for a DC vigor provide to create ample heat to generate mild from the aspect. Nonetheless the do make mild bulbs that are designed to function on a DC energy supply and i might extremely recomend making use of the proper bulb with the proper vigour provide. Purchase some 2volt bulbs to be dependable......
Q:Can solar panels be used in areas with high levels of air turbulence or strong winds?
Yes, solar panels can be used in areas with high levels of air turbulence or strong winds. However, it is essential to ensure that the solar panel installation is designed and mounted properly to withstand these conditions. The panels should be securely fastened and angled correctly to minimize the impact of strong winds. Additionally, using durable and wind-resistant materials for the solar panel structure is important to ensure their longevity in such areas.
Q:Hi there. I live in Colorado, and we obviously get a ton of snow there. I im looking into a solar power system for my home, and I am wondering if the snow will accumulate on the panels, or if, because of the energy passing through, it will melt on contact? By the way we get about 20' of snow each year, and it comes on often. I will also be putting them on my roof. Thanks for your help.
Good news and not so good news. You need to be able to access the panels to clean the snow off. There is not any heat generated other than the heat of the sun hitting the black colour - which would amount to some melting ability during a sunny day - but it isn't sunny when it snows! Apparently, solar panels work better in the cold and where snow can reflect light so to increase the amount of light - photons - hitting the panel.
Q:What are the supplies needed in a solar panel field, i know there are the panels. But what about batteries, and converters. Possibly other things, and how many will i need, for a certain amount of panels?
Short answer.. alot. A solar field is a big undertaking, and you'd be better off going with a solar consultant. I found this site and would recommend their services as they offer consulting, and are pretty big into solar (or atleast in my area..)
Q:What makes them stop working after a while?
could be temperature, poor design and U-V damage If they are outdoor lamps like mine it is more likely the rechargeable batterys are bad.
Q:Hi, I am very interested in solar panels and would like to know more.Can someone please give me a basic explanation of how solar panels work?Thank you
A solar panel is made up of many small solar cells. Each solar cell uses light to make electricity. The solar cell uses light to make electrons move. The cell is made up of two different layers that are stuck together. The first layer is loaded with electrons, so the electrons are ready to jump from this layer to the second layer. That second layer has some electrons taken away. It is ready to take in more electrons. When the light hits an electron in the first layer, the electron jumps to the second layer. That electron makes another electron move, which makes another electron move, and so on. So the light started a flow of electrons, or electricity.
Q:How do solar panels perform in extreme temperatures?
Solar panels can still generate electricity in extreme temperatures, but their performance may be slightly affected. High temperatures can cause a decrease in efficiency, as the heat reduces the panel's ability to convert sunlight into electricity. However, modern solar panels are designed to withstand a wide range of temperatures, and their efficiency losses are generally minimal. In extremely cold temperatures, solar panels can actually perform slightly better due to the improved conductivity of the solar cells. Overall, while extreme temperatures can have a small impact on solar panel performance, they are still a reliable and efficient source of renewable energy in various weather conditions.
Q:How can I determine the size of solar panel system I need?
To determine the size of the solar panel system you need, you should consider factors such as your energy consumption, available roof space, and geographical location. Start by analyzing your average monthly electricity usage to estimate the amount of energy your solar panels should produce. Next, assess your roof's orientation, tilt, and shading to make sure it can accommodate the necessary number of panels. Lastly, consider your location's sunlight hours and climate conditions, as they affect the efficiency and output of solar panels. Consulting with a professional solar installer can also help you accurately determine the size of the solar panel system you need.
