Q:Simplfy it so i can understand pls and put it in stages such as . sun hits solar panel plsHow many different types of solar panels are there?: Sunlight hits the solar panel, and DC power is generated. By the power is not stable. It becomes stronger or weaker according to the strength of sunlight.

Q:Main questions: How can I work out the efficiency of a solar panel and how can I work out if the panel is relatively cost-effective? Also what type of solar panels is considered most effiecient?Let's assume that all relative values are available.Secondary question: What type of safety regulations and licenses are required to be fulfiled in order to import solar panels into the EU from non-EU countries?: The manufacturer of any serious panel should be able to provide an efficiency. That will be the STC power rating of the panel, divided by the area of the panel, divided by 000 w/m^2. But the more interesting figure is cost effectiveness, as you say, which is nothing more than cost per watt for the same class of panels. Most applications are limited by money, not by area.

Q:Pls is it ok to connect a 0watt and 20watt solar panel together into a charge controller port, can i just tie the wires together and run into the controller?? Will damage anything...Thanks guys: Tobi, generally yes, solar panels are like beer, all the europeans get along fine, you can put two Belgiums in the same room as one German and three Englishman. As long as the panels have roughly the same open circuit voltage, usually around 8 volts, then go for it. If you're not sure about this, or the panels voltage disagrees dramatically, then they can still work through the same charge controller, the only other thing you need is a bypass diode in the junction box on the back of each panel. Most modern panels come with these already installed. They are simply electrical check valves, allowing current flow in one direction but not the other. The reason these matter is when the sun is first coming up, the higher voltage panel can force its power backwards through the lower voltage panel, at least until they both reach a voltage higher than the charge controller is set at. This is not a desirable thing to have happen, the 20 watt panel, if its voltage is higher, can damage the 0 watt panel without these diodes if the 20 watt has a much higher open circuit voltage, or Vmax. Look on the back of the panel for these ratings. The only other concern is maximum current. A charge controller has a maximum current it can handle, they are generally model numbered this way, a Xantrex C-60 for example has a 60 amp rating. Add up the Imax numbers on the back of all your panels, this is the maximum amperage the panel should put out. As long as it is not above 80% of your charger controllers maximum amperage, your good. Take care, Rudydoo

Q:Can solar panels be installed on a sports stadium or arena?: Yes, solar panels can be installed on a sports stadium or arena. Many stadiums and arenas around the world have already installed solar panels to generate clean and renewable energy. These panels can be mounted on the rooftop, parking structures, or even integrated into the facade of the building. The large surface area of stadiums and arenas makes them ideal for harnessing solar energy and reducing their carbon footprint.

Q:how does solar panels work?: Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect. The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.

Q:I have purchased a 2 volt LED lantern from argos, it comes with a built in 6 volt 4ah sealed acid battery. What I wanted to know is would I be able to charge it using my 6 volt solar panel?: If it has a 6 volt battery- is it marked 2 volts on an external plug? If so, there is a resistor inside to drop the potential the battery sees. The battery itself could be slipped out and recharged easily from your 6 volt panel. Just determine how much current (in Amps or Milliamps) the panel produces nominally and divide that into 4 and add one fourth of that length of time to make up for system losses. This will tell you how many hours it should charge assuming your starting voltage of the battery is above .5 volts. and the panel is at 3 volts potential or higher. So if your panel puts out amp at 0AM, you would charge for 5 hours. 4 divided by is 4 and one fourth of that is so 4 plus is 5. It is a little more involved than that, but as a rule of thumb. Also do not discharge tha lantern to the point of no light output. LEDs are efficient, but their current will add up. If it is suggest to be able to use the lantern for up to 8 hours on a charge, stick to that value. Lead acid batteries have best longevity when discharged only to 80 percent capacity. Once battery is charged- disconnect from charging source.

Q:I have been thinking about getting solar panels for my house. What do you think I should get? Companies? Prices? I also have another question. How much energy can a small solar panel produce?: You okorder /

Q:I am in the market for buying a home. There is one for salke that actually has solar panels on top. How are they used? Do you need to pay for gas and electric still. Does it really light up the house and keep it warm. WHat about the AC keeping hte house cool in the summer does it work for that too? Please explain in solar for dummy terms. I haveno clue about solar panels other thatn the fact that it needs sunlight to run.: I think that rustoria67 bumped his head on some thing. There are thousands of homes using only solar panels to power their homes, and it no way near an acre of them. With the right setup Kw of panels will work. Remember one can't bring a boat to an airplane race and hope to win. Look at this link.

Q:they are pretty expensive. So does it save you money on electricity in the long run? How easy is it to connect solar panels to your house?: I did. image voltaic capability components approximately seventy 5% of my electricity and decreased my electric powered invoice from approximately $a hundred and twenty/month to basically $35/month. I won a rebate from my state and a few tax deductions so my internet out-of-pocket value became approximately $6000. I stored a team of money via doing lots of the installation myself. As of right this moment my gadget has generated sixteen.5 megawatt hours of electricity simply by fact it became put in. the internet web page the place i offered the gadget is indexed decrease than and likewise an particularly stable mag on residential image voltaic capability is indexed decrease than. the two websites have very stable tutorials for human beings questioning approximately image voltaic. additionally based upon the place you reside wind capability could be an particularly stable option for you. in case you have a stable wind source it is going to be a greater value-effective thank you to generate capability.
