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:are biological solar panels possible?
There are, in fact, protozoa that use chlorophyll to harvest sunlight, but the thing is, they also MOVE. So it's not entirely unreasonable that an animal cell could do the same.
Q:Can I join 5 or more solar panels into line to the battery bank. I don,t have a regulator connected, just st?
You can do this, but it isn't the best way to go. There is no problem with joining the solar panels. There are two ways to do this, in series and in parallel. A series combination will add the voltages that each panel is producing together, but not the amperages. For example, if five panels are producing 6V at 300mA each, the end result will be 30V at 300mA for a series array. A parallel combination combines the amperages of all the panels, but not the voltages. So, in our earlier example, five panels at 6V and 300mA would provide 6V and 500mA (.5A) if wired in parallel. Series-parallel combinations are also possible, giving some of the benefits of each method. This would probably better understood by doing a quick search on Google Images for series, parallel, and series-parallel. You CAN connect the solar panels directly to your battery bank with no regulator. Unfortunately, without a regulator, the connection is two-way. When the sun is out and the solar panels are producing more voltage than the batteries, the batteries will charge. However, when the panels are producing less voltage than the batteries, the batteries will instead send power into the solar panels, which will be dissipated and wasted. The panels may charge your batteries during the day, but they will discharge them at night.
Q:It's all about Solar Panels?
here's lot of articles about the questions you just asked about solar panels, enjoy renewableenergyarticles.blogspot....
Q:Where are the best places to put solar panels?
The best place is where they get the most sunshine. Naturally they will be exposed to rain and snow.
Q:Has anyone had roof problems caused by rooftop solar panels?
Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.

Q:if you put solar panels on cars, you'll be able to drive without gas in the summer and part of winter?
Understanding Physics and something about electrical power is normally needed to solve this problem. Here is some info that may help put it into perspective: One average solar panel approx 3ft. X 4 ft may produce 00 watts of power during peak performance times. A VERY small car will require a minimum of say 0-30 HP to be viable. (An old VW had 40HP) 00 Watts continuously will produce about 0. HP (/0 of one HP), so to get 20 HP, I would need how many panels? About 0 panels to get one Horsepower? Where do I put them? note: ONE HORSEPOWER = 746 WATTS SOLAR IS GREAT, BUT NOT CHEAP AND NOT RELIABLE ENOUGH IN MOST AREAS TO DEPEND ON FOR NECESSITIES. IT IS VERY GOOD FOR SUPPLEMENTAL POWER USES AND CAN REDUCE OUR USE OF CONVENTIONAL FORMS.
Q:Im looking at getting solar panels.
Your problem will be the days that are too cloudy, rainy, (snowy won't apply since you will need A/C during summertimes) and the night hours when there is no sunlight. A battery might be okay for a while but if you have to have a good one. Is there is a battery that can run an air conditioner for long without crapping out! I don't think you will ever recoup your investment.
Q:How much energy does this particular solar panel produce?
It's virtually impossible to estimate how many panels would be required, without knowing your electrical usage, and where the house is located. I'll give our house as an example, but it could be off by a factor of 0 (not kidding) from yours. We have gas heat, no air conditioning, and no pool. We live in a dry, sunny area of California, and our roof is ideally oriented for panels. We would need 25 such panels, but we are grid-tied. If we wanted to disconnect completely from the electric company, we would need 20% more panels to compensate for battery inefficiencies. So, the estimate is 30 panels. Here are some caveats: ) Air conditioning, especially central air, could double or triple the estimate. 2) An area that gets less sun per year (northern US, for example) would need more panels. 3) Typically, when a house has grid electricity, they keep grid electricity when they get solar panels. It's much cheaper to use both in tandem. 4) That's a horrible price for the panel in the picture. You can find a 200-watt panel for less than that. 5) Other equipment is required besides the panels to run your house off solar. You can read up on it on the internet, or ask a professional solar installer for a free quote.
Q:can a small solar panel be charged with lamps?
Sure!...did you ever use a solar powered calculator indoors under a lamp?? It works just fine.
