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.

Q:Solar power panels?
It sounds like you nor anyone at your home knows enough about solar to be able to hook them up no matter what type they are. I have to agree with others that they could be hooked up and you just can't see the connections. So the best thing for you to do is get a contractor to come out and check them out. It don't have to be a Solar Dealer because I am a dealer and I use electrical contractors to do the installs. A solar dealer is not always legal to install and normally do like I do and just design and sell the systems. However most any dealer can easly install a solar power system because they are trained just not legal to do the work. Having someone other then an electrician work on it could void the warranties.
Q:Please differentiate b/w mono & poly crystalline silicon solar panels.?
In the practical sense, the differences are trivial. I'd buy on price per watt, unless space is at a premium (it isn't for most installations).
Q:How does solar panel help/affect the economy?
As other sources of energy become more expensive due to declining rates of production, or increased costs for safety or pollution controls, solar energy becomes more practical as a method of gathering inexpensive supplemental energy. Look at the german experiment, where rooftops in germany were covered in solar panels and wired into the house system to supplement energy needs. In some places, I'm not sure about Germany, you can actually sell back surplus electrical energy to the power company if you have more capacity than you can store in the batteries attached to the panels. Keeping energy costs lower than they would otherwise be helps the economy by making growth less difficult for new and existing companies, and puts money in the hands of consumers that they otherwise would have had to spend on electricity. We need some additional innovations in battery technology and solar panels to make solar a mainstream source of energy, but replacing roofing with solar panels is a very interesting idea that might become a mainstream building practice if the cost of other kinds of energy keeps rising.
Q:How Do solar panels work?
Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .
Q:Solar Panel Question?
Your local installer will estimate this much more precisely than I can. Your main problem, as I see it, is not that you need this many solar panels. Your main problem is that you consume WAY too much electricity. You should probably cut your energy consumption in half BEFORE you invest in solar because it will be way more economic to eliminate the main consumers than to generate that wasted energy. I, for example, need no more than 80kWh/month for a household of two.
Q:how can you make your own solar cells for solar panels?

Q:What is the most efficient solar panel?
Most Solar Panels are roughtly 6% efficient. Since the sun gives out about 366 watts per square meter, a good panel would be 200+ W/square meter. If you want to save a bunch of money, I suggest you have a look at this tutorial I'm linking. The guy explains how you can assemble your panel yourself. It's far easier than I first thought !
Q:How much is the average solar panel?
Completely self-efficient and autonomous??? Forget it. Too expensive. It's only worth if you use like 8 lights (2-20w) about 4 hours a day, a fridge, a tv about 4 hours/day and basically nothing else or a few low consume stuff. Forget about microwaves, dryers, or other stuff. Too much watts. And that would cost you no less than 5000-6000$. You need panels (about 4 or 6 20w would suit maybe), 2 batteries (about 600Ah at least), inverter(500w/24v) and a regulator, lets say a 30A one. Just stick to normal energy supply. A single 20w panel may cost about 750$ at least.
Q:Information on Solar Panels?
If you hope to get a solar panel that can run appliances and air conditioning.. then you are not even close to being realistic about what solar panels can do. If you really want to install a solar panel array on your home, then you need to talk to a company in your area that designes and installes them because every installation is different.. so you won't get an answer here on Yahoo. You can expect to spend $20,000 to $30,000 that will provide enough solar power for the average home.
Q:Solar panel placement idea?
outside is going to be much better. You can't tell but glass is actully opaque to many ranges of 'light'. If you look at advertising for windows you may see claims to reduce sun fading of your carpet/ furniture. That is because the glass blocks UV. Solar panels get some of their energy from UV light. Also some windows are engineered to block IR to help insulate better when the house is cooler than the outside. Again, solar panels get some of their energy from light in the infrared range. And finally if you're charging batteries the 'off angle time' is still important. The amount of light absorbed is pretty closely related to the cosine of the angle that the sun is 'off' of the direct. so when the sun is 45 degrees off of perpendicular the panels still get cos45 =.707 or about 70% of the available energy. (In practice it's a little less than that because not as much energy gets to the panel to be absorbed as at midday). But anyway, you can figure two hours of morning or late afternoon sun will give you as much energy as hour of midday sun. So if the panel is inside, you miss out on that available energy.
