Solar cell module production process
Line called packaging line components, packaging is the production of solar cells a key step in the packaging process without a good, multi-well battery is also not a good component of production boards. Battery package not only the battery life is guaranteed, but also to enhance the combat strength of the battery. Product quality and high service life is to win can be the key to customer satisfaction, so the quality of components of the package board is very important.
Process is as follows:
1, the battery test
2, positive Welding - Inspection –
3, on the back of cascading - Inspection –
4, laying (glass cleaning, material cutting, glass pre-processing, laying) –
5, laminating –
6, to flash ( to the side, cleaning) –
7, fitted border (glue, loading angle keys, punching, install box, scrub I glue) –
8, the welding junction box –
9, high-pressure test –
10, component testing -- -
11 appearance inspection, packaging and storage;

- Q:Do solar panels require a battery for energy storage?
- No, solar panels do not require a battery for energy storage. They can be directly connected to the electrical grid and the excess energy generated during the day can be fed back into the grid and used at night or during cloudy periods. However, batteries can be used to store the excess energy for later use, especially in off-grid systems or areas with unreliable grid access.
- Q:quot;Does it take more energy to produce a solar panel than what the same solar panel can generate in its useful lifetime?quot;
- No. okorder /... Since then they have only improved. CdTe efficiencies have increased, partly by reducing material use (particularly the depth of the CdS layer)
- Q:About how much would it cost to purchase and install solar panels for the average American house so that the house can be off the power grid and use the same amount of electricity as it normally does?
- I had a survey of my home and it was estimated at $30K with a 30% rebate from the government. It would take about 5 years to pay back the cost. I elected to go solar water heating instead. 2 panels with piping installed to an 80 gallon electric water heater with an internal heat exchanger. One small photo voltaic panel to run the pump. There is ethylene glycol inside the pipe and it circulates and heats the water. Works excellent. I live in Nor-Cal and we get a lot of sun. I need to comment on another statement that photo voltaic cells cost more energy to produce they generate. Maybe once but not true any longer. {Solar cells and energy payback In the 990s, when silicon cells were twice as thick, efficiencies 30% lower than today and lifetimes shorter, it may well have cost more energy to make a cell than it could generate in a lifetime. The energy payback time of a modern photovoltaic module is anywhere from to 20 years (usually under five)[9] depending on the type and where it is used (see net energy gain). This means solar cells can be net energy producers, meaning they generate more energy over their lifetime than the energy expended in producing them}
- Q:right now, you would need a suitable number of solar panels just to power house that can take up a lot of real estate. so my question is, is it feasible to create something that absorbs more of the suns energy like a magnet it would suck it up. the point of doing this would be so that we wouldnt need so much space so many panels just to power home for example.i hope thats coherent.
- we are near the edge of what is physically possible for solar power. You only get so many photons per area you know...and much of this is lost in entropy. Solar panels today are over 80% as efficient as what could ever be theoretically possible. No you will never get an easy solution to the land problem. lol what invisible talker suggests about using a black hole i suppose could be a way to increase the photons per area...but you would get much mroe power by using the tidal forces produced by a black hole than solar power heh...not to mention your panels will get sucked in...and whatever energy they produce wont be able to escape the black hole and power anything outside.
- Q:Photo-Voltaic solar panels are very expensive. Most of a home's energy needs are for heating water, heating and air-conditioning. All of these can be met with thermal solar collectors which are much less expensive. The thermal solar panels would heat water stored in a hot water tank which then can be used as hot water, to heat the home, or as the heat source to a Lithium Bromide Absorption chiller to air-condition a home. With the base line needs met without expensive panels and without inefficient energy conversions, only a small Photo-Voltaic array would be needed for the remaining power needs and since those needs are variable, there would still be power to sell to the grid.
- I agree with you John and for the same reason already put forth as a negative. Solar thermal is a more mature technology. This is the reason why I spent so much of the last winter studying it. I can be reasonably sure that what I learn will not be obsolete tomorrow with a new technological breakthrough. I built a solar addition/greenhouse to personally study the effects. So solar thermal panels are not the only way to go. With respect to electrical production. I have seen parabolic reflectors coupled to stirling engines and solar thermal trough heaters used to supplement steam generation for alternatively gas fired steam / electrical generation plants. On a trip to China over 4 years ago I noticed solar hot water vacuum tube collectors being sold in their local hardware and big box style stores. These were gravity fed package units intended to have the tank on the roof with a supplemental electric backup. The vacuum tube collectors seem to be one of the latest innovations in this technology. Using phase change materials temperatures in these panels can be produced in excess of 400 deg F. and they are useful in colder temps and on cloudy days. While they are still costly for many applications, I have been discussing the use of vacuum tube collectors with the owner of a laundrymat. Solar thermal will not pay back as well as conservation in many cases of older construction, but it currently seems better than photovoltaic panels. Solar thermal requires more understanding of systems and relative efficiencies. In one way solar thermal is more like the electric car while the internal combusion engine is like photovoltaic. The idea of producing electricity from the sun is a sexier idea. It is also more in line with our paridigm of: just producing lots of energy and to H with any conservation efforts. For that reason it seems to get more press.
- Q:Can solar panels be installed on carports or pergolas?
- Yes, solar panels can be installed on carports or pergolas. In fact, these structures provide an ideal space for solar panel installation as they offer ample sun exposure and can optimize energy generation while providing shade or protection for vehicles or outdoor spaces.
- Q:Can cold light make solar panels power
- Solar power generation There are two ways of solar power generation, one is the light - heat - electricity conversion, the other is the optical - electrical direct conversion.
- Q:Can solar panels be used in areas with high levels of sand or dust deposition?
- Yes, solar panels can be used in areas with high levels of sand or dust deposition. However, the accumulation of sand or dust on the surface of solar panels can reduce their efficiency. Regular cleaning and maintenance of the panels are necessary to ensure optimal performance in such environments. Additionally, the tilt and positioning of the panels can be adjusted to minimize the impact of sand or dust deposition.
- Q:I want to know how many solar panels to use to power my AC and Water heater
- you cant use solar panels to power your house, it would take more than you can afford,and space to mount them and all the equip required to hook it up. what they don,t tell you is you need a Battery bank [24 to 48 batteries], deep cycle a inverter ,[one that will convert 2 volts to 0, at the wattage you need ] a transfer switch, rated at 00 amps wiring, a 45 watt panel is around $300
- Q:where to find used solar panels?
- IF used panels are available, they are probably worn out and NOT putting out the power they were designed for. (They DO wear out!) I do NOT know of any place they are sold.
