Solar panel working process

In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.


Specification of Solar Monocrystalline  Series

- Optimal permutation on solar cells to keep enough heat diffusion, decreases hot spot effect.
- High quality and anti-ageing EVA, weather resistance backside raw materials assure reliable solar panels.
- Passed 5400Pa mechanical loads testing by UL, can withstand bad and high mechanical load working environment.
- With good sealed performance, moisture resistant, aging resistance, high/low temperature resistant, the inner terminals of our junction box owns good electrical performance transmission. Bypass diodes used can avoide hot spot effect and damages to panels. Output cables and mating connectors are safe and reliable for installation application. Adopt weather resistance, sealed, good sticky silica gel when assembling.
- Strict quality inspection on each procedure and 100% electrical performance test to meet power requirements.
- 0~+3% power tolerance.
- classification for all the panels in order to improve the integral performance of system and solar panel life span.
- TUV、UL、MCS、CE、ROHS、Golden Sun certified
- Underwriting of 25years output power warranty by The People's Insurance Company of China.

Q:How would you build a Solar Panel that can convert Sunlight to Energy, just being on your house roof?
The panels themselves- no. Minimal. For most it is just hosing them off with water as needed to remove dust. Battereis on the other hand are usually needing attention every week to maintain the electrolyte levels. The exception being AGM types. Periodic desulphating may be needed on older setups, but beyond that keeping chickens are more demanding. Batteries are how you store your energy for periods when demand exceeds what the panels can deliver, and at night. How many varies. Factors of how you use energy has most impact. Some people can get by with a few hundred Watts, for others 3 to 5 Kilowatts are needed. For the average American, 5 to 7 Kilowatts as a minimum without some serious changes to how energy is used.
Q:how long do roof solar panels last?
Ive been using the same solar panels for 5 years, have move a few times so they last a lot longer than the roofs weve had over us. I am teaching my kids how to build wind generators, because we keep having power failiures when the wind blows. and recently its got very windy. I charge banks of battery's and keep my office running from dc-ac converters.
Q:How much was the price of solar panels 5 years ago compared to now?
I okorder.com to register for free and lock in long term costs. The increasing demand and competition is helping reduce costs.
Q:Want to power this with solar panels?
You won't get very far with THAT lash-up. First of all.. WHY would you want to use diodes to drop the voltage.. they DRAW CURRENT and that is something you don't have to spare. That draw of 4.5v@0.66A (660 ma) comes out to just under 3 watts. You DO KNOW that you can get that 4.5 Volts by driving a NAIL into the THIRD CELL in a 6 Volt wet cell battery... right? and for what you are doing, you have more current available with a 6 volt battery than a 2 volt battery. Anyway, you could use two 6 Volt batteries and tap them at the 4.5 volt point then tie them in parallel, but you could still use the 6 volt solar panel to charge them. Trying to use an inverter is just an exercise in futility.. With TWO of the LARGEST DEEP CYCLE BATTERIES you can buy at AutoZone running in Parallel and being charged by solar panels.. if you hook a 75 watt inverter to them, they will go flat in about 4 hours of use during the night. This is not rocket science. Back when cars were changing over from 6 volts to 2 volts, I powered up more than one 6 volt car radio off a 2 volt battery... when you grow up as poor as I did.. you get inventive. I later used the same trick on the 24 volt electrical systems the Jeeps were using, to power up clandestine repeaters in places where no repeaters should have been. About 25 years ago I was living in the Denver area and built up a 0 watt 2 meter repeater on a split channel and took it up to Mt. Evans during the summer and hid it in a pile of rocks. I used tone control, so we were the only ones using it and, as I said, It was a split channel.. so it wasn't on a regular repeater channel. That thing was still running when I moved from the Denver area about 3 years later and for all I know, It's still up there on Mt. Evans (find the Brittlecone Pines and look towards that small peak about a mile to the west)
Q:Whats the annual energy output of the average solar panel.?
The Sun provides about 360 W per square meter above the atmosphere (Solar Constant). Approximately 2/3 of the energy is lost in passing through the atmosphere, which means you should anticipate at best about 450 W per square meter arriving at a solar panel directly facing the Sun on a clear day. You can anticipate an efficiency of approximately 30% for a typical solar collector, or about 00 W to 40 W per square meter of solar collector being delivered as electricity under the best of conditions. These are estimates, but we need better information on the actual power delivered per square meter of a particular solar collector under the best of conditions before we can begin to estimate the amount of energy per meter squared collected over a typical year for a given location.
Q:I need help with solar panels?
Even if you can buy solar glass, you CAN'T properly repair the panel for the cost of having a professional do the work.
Q:have you ever installed solar panels for your home?
Yes I have. We have a little Labrador on the front steps(you know, a thing to hide keys under.) In his mouth is a little lantern that absorbs the solar energy from the panels and it turns on at night. Really saves you money, much more than regular electricity. The bill won't be so high this way, oh, and it's also good for the environment����
Q:Designing 3d Solar Panels?
I don't know anything about the 3D thing. You cannot get more energy out, than goes in. Energy will only hit the mirrors. With some loss of efficiency they would reflect a focused beam into the chamber, where with some more losses would reflect it to the solar panels. It would be more efficient just to expose all the panels to sunlight.
Q:How much do solar panels generally cost and are they efficient for my home?
At the present time, even with the government paying some, they are not cost effective. If you live in middle of nowhere and you want to be prepared in case all Hell breaks loose, and you can install your own, then I might consider them as a backup plan only if I did not have a running stream with 0 feet of drop. You can make a water generator really cheap if you have that creek. Call a solar panel company and get a quote. Do the math and see how long it takes for pay back. They are also allergic to hailstorms. My son did and it was something like 40 years to break even.
Q:What home appliance can be powered by a solar panel?
Solar panels could supply an air conditioning unit but it would be SUPER expensive to do. Air conditioners are power hogs.
