Q:Do you need to pay for electricity if you have solar panels?
Okay--here it is (without the techie buzzwords!) Solar power has a start up cost--the panels and related equipment. But the amount it cost to operate is virtually zero--pretty much jsut servicing th equipment o keep it working properly--much as you do any other appliance. How much electricity you will still have to buy depends on four things: a) how much your system can produce. If you have a 4000 watt system, you'll still buy a fair amount of power. Abigger one--and you will need less from the power company b) how efficient you (your home and appliances are). The more efficient, the less electricity you use. Obviously, things lie CFL bulbs are very helpful here c) Are you willing to invest in a battery storage system to store electricity from the system for use at night? Right now, that's still pricey. But these are starting to come on th emarket more. If you aren't ready to do tha tnow, you can always add it in later. d) can you sell excess power back to the power company.? In California, the law requires utilities to do this--but its not a universal yet, so it depends on where you are. How this works: you are still hooked up to the power company. Any time you need more power than the solar system produces, yur system jst draws it off the power grid--jsut as always. But--any time you are using LESS than the amount of power your system is producing, the excess automatically feeeds back into the electric grid and a special peter credits you with the power. There are cases wwhere people have goene on a long vacation in California and when they got home, the power company owed them several hundred dollars! You'll need to do some research, price thngs, take your own lifestyle into account, and decide what the best choices for you are. It sounds complicated--and to an extent it is. But the reason is tha tyou have a lot of choices tha tyou can make work to your advantage, instead of jsut writing a fat check to the power company every month!
Q:Whats the annual energy output of the average solar panel.?
The energy output is highly dependent on the location. For a specific area, you can look up the equivalent peak sun hours per day here: rredc.nrel.gov/solar/old_data/nsr... Let's say that it says the peak sun is 5 hours / day in your location. Then a typical 200-watt panel would have 5 x 200 = 000 wH = .0 kWh per day, or 365 kWh annually. The tables above already take into account average cloudy days, and seasons. A typical size installation would have perhaps 6 of these panels, but it could be less, or much more.
Q:List of new solar panel manufactures?
Leading vertically-integrated PV company. Manufactures top-quality Poly-Si/Mono-Si modules in India. The company distributes/provides solar-power systems services worldwide. USAManufacturer and developer of high-performance silicon solar cells. Their proprietary Bright Point technology utilizes impurity-enriched silicon to efficiently convert the sun’s power into electricity. Suniva develops, manufactures and markets high-efficiency silicon photovoltaic (PV) cells. Suniva's focus is solely on silicon PV cell technology and manufacturing and does not engage in any of the downstream integration or manufacturing of modules or products which use its cells.
Q:I need help finding Solar panels for a boat.?
Rate ,power , voltage and effencicney are four important iterms to choose one battery.
Q:Solar Panel System companies at the swapmeet?
Hard to say. Solar panels are becoming more common these days. May want to ask if the vendor is licensed and bonded contractor (if he's doing installation as well as panel sales). Find out the name of the equipment that this guy is selling (panels and other hardware) and do a search. For that matter, get the guys name and do a search on it to see he pops up elsewhere.
Q:Need help with a solar panel?
In order: .  Just about any wire will do.  You can handle 50 mA over just about anything, even 28 gauge telephone wire.  Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.  You need a diode.  If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.  The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.  You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.  This gives you maximum current output from your panel.
Q:Information Regarding Solar Panels?
366 W/square meter on March 2 and tweaked based on lattitude eff = W out/Sun W in there are special heat meters to measure W in ======== IEC 62688 Certification; and UL cert in USA
Q:2V Solar panel directly to 2V inverter...and restult.?
. A 5 WATT panel can NOT power a 300 WATT inverter. 2. IF using 2 volts, then you need a 2 volt battery in the circuit as well. Panel charges battery which powers inverter. When the inverter pulls more power than the panel puts out, it gets it from the battery until the voltage drops low enough to shut down the inverter. NOTE: SOME cheap units do NOT have protective circuitry, and when the voltage drops, the current rises and burns them up.
Q:how to build a solar panel?
Can you show us how to build a solar panel ?
Q:Solar panel trouble?
Most solar panels convert the energy collect from the sun directly into usable DC current. So no, you do not need a capacitor to test a light if you are in sunlight. You will need a capacitor or rechargeable battery if you plan on testing the solar panel away from a light source after the capacitor or battery has charged. Solar panels cannot store electricity.
