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:What is a good solar panel to buy?

Q:Nuclear reactors vs. Solar panels?
You should research nuclear reactors and their emissions. Mostly it's waste heat, and if they use a water-based cooling reactor, there can be significant emissions of water vapor. Some might consider the spent fuel an emission too. Waste nuclear material disposal is a problem. Research it. Solar panels have no emissions during operation, but there is some nasty stuff emitted when they are manufactured. 2: Maintenance of solar panels is pretty straightforward: keep them clean, trim overhanging trees, shrubs, etc., check for and clean corrosion, contaminants, etc. regularly. Maintenance of nuclear power plants, so far, is a full time job for many technicians and engineers. The recently developed portable (the size of a shed) nuclear generators claim zero maintenance for 20+ years. That's a big improvement.
Q:Can cold light make solar panels power
permanent, clean and flexible three major advantages of solar cells long life, as long as the sun exists, solar cells can be an investment and long-term use; compared with thermal power, Solar cells do not cause environmental pollution
Q:Solar Panel load resistors?
Photovoltaic cells have a load curve that gives the power conversion based on the current drawn. This makes it harder to calculate. For instance, at infinite resistance, the solar cell will have a peak voltage that produces no power (P=I*V=V^2/r). At short circuit, the voltage collapses to essentially nothing and so the power is almost nothing. There is an optimal load (sweet spot) where the resistance applied will draw the most power out of the cell while not overloading it. This measure is either given by the manufacturer or found experimentally. Upon taking a lit panel that has no load and applying a 00 ohm resistance, the voltage will drop. By how much is entirely dependent on the array layout and specific cell characteristics. As the resistance drops from the optimal load point, the voltage collapses fairly sharply. As the resistance increases from the optimal load point, the voltage will rise more at first and then level off to the peak or no-load voltage.
Q:Please explain KW Solar Panels. What does it mean.?
It means that it will produce (at best) 5kW when the sun is shining in an ideal position, in hour that's 5kWh so, on a good summer day it may produce a total of 25kWh nothing at night see the link for a 5kW system, you need at least 0 possibly 20 times that.
Q:How many Solar panels?
Quite a bit to run 480 volts @ 50 amps. Ohms law will give you the basic level your looking for but also you need to consider power storage ... Conversions .... Start up power vs running power levels ... it can be done but this is a bigger system then what I need so I cant just give you an number your panels will be rated in wattage and amperage you then take that power and put it in storage (battery) to inverter system (mine is 20 volt) you will need to have a 480 inverter for your power level. good luck hope I was of some help.
Q:Why are solar panels so expensive?
The only way I know of is to invest the money in the stock market. Most savings accounts only pay 3% intrest. While stocks float and if you don't know what you are doing you will never make as much money as you could save on your electric bill. Then the fact that you have to pay the electric bill out of the money. In the end you rented electric and can never get your money back. You can always sell the solar electric system and get your money back plus a profit. Not many people live in the same house even 20 years so it will sell. Toss the coin. It is what ever is best for you.

Q:how much do solar panels cost and r thay worth buying?

Q:Solar panel wiring, materials?
the solar panel should state it, you dont need a inverter to charge, only to use the power from the cell.you do need an amp regulator, so it tells if the battery is on full charge and so the sun doesnt over power the battery through the solar panel
