Q:How does solar panel help/affect the economy?

Q:Solar Panel Efficiency?
I've operated a 25 kilowatt (kw) solar panel system for two years (44 panels, rated at 90 watts each, just about like yours). It averages 0 kilowatt hours (kwh) per day, but clear days get about 60 kwh. My system generates about 3300 kwh per month (we dump directly to grid), worth about $4,000 per year. Payback for my system, which cost $00,000 (after utility rebates and tax credits), is 25 years (the expected lifetime, coincidentally). Under similar conditions, your 200 watt solar panel would average 820 watt-hours per day, or about 25 kwh per month, worth $2.50.
Q:Computation of Solar panel requirement?
The power output of a solar panel uses a formula to determine kilowatts produced per hour per square meter per day. This calculation is important because, if you plan to install a solar power system for your home, you will want to know how many solar panels will be needed. To calculate solar power requirements correctly, you need to gather the data that is needed for the calculation. First you have to find the average amount of solar radiation available for your area. You can use a solar radiation chart. This can range from a 4 to a 7 depending on the area you live in. Write the number down on a piece of paper and indicate it with the letters RA. Next is determine the amount of electricity that you use daily. Add the kilowatt-hours used per month from your utility bill. Multiply this number by ,000 to get the watt hours in a month. Divide the total by 30 for the amount of electricity you use daily. Write this number down and indicate it with the letters DE. Determine the percentage of your home that you want to power with the solar power system. Write this number down and indicate it with the letter P. Determine the system inefficiency factor for the solar power system. You should be able to find this on the brochure for the system or from the manufacturer's web site. Write this number down and indicate it by the letter I. Determine the power or yield that is required for your home. Use the equation P = I x (DE x P) / RA to find the power requirements in kWh. Divide the number from Step 5 by the peak wattage for a single solar panel to determine the number of panels you will need for your home. Goodluck! :)
Q:Solar Panel Circuit Question?
Do you know what is the rated Peak watts of the solar cell and the current needed to operate the relay. The power needed to operate the relay can be found from 9V * operating current, and that should be lower than the peak output power of the cell (perhaps significantly less as the peak power is produced only at high solar radiation levels. Another factor is whether the curves for the solar cell match the load. Typically the solar cells have a knee type diagram for the VI relationship, and that is why they need Maximum Power Point trackers to deliver a good power output.
Q:where could i buy a cheap and low cost solar panel regulator?
try OKorder..i know it sounds corney but someone might be selling one, if not try your nearest hardware store? Like ..lowes..orsomething.
Q:QUestion about portable Solar Panels.. Mine is 2v?
Like others have reported, the voltage may well be 2v, however the amperage is approximately .0 amps Thats the capability of photograph voltaic. relatives shops are monsterously greater useful. yet, the voltage is there, and the amperage is there, including that's- so, that photograph voltaic panel might desire to cost up a monetary business enterprise of four 2v batteries under pressure jointly in parallel.... it in simple terms could take approximately 3 weeks. it can be a great trickle cost. I play around with little 6v photograph voltaic cells, and in case you choose to work out it artwork, positioned a huge can capacitor around the photograph voltaic cellular leads for a minute or 2, then touch the capacitor to the motor leads... it is going to turn- proving the capability is actual. you in simple terms desire the Capacitor to save it up for slightly. interior the tip all of us have been given spoiled on the quite extreme performace capability of plug in electrical energy and chemical cellular batteries. Given the designed capability of those, any option source of capability is confident to be disappointing.
Q:What capacitor should i use to store energy from a solar panel?
If you have a rechargeable AA battery (NiMH or NiCad) that might work. You're not going to get much power from that size array anyway, especially if it is not in full sunlight. A Farad (F) is ,000 times bigger than a milliFarad (mF), which is ,000 times bigger (stores ,000 times more) than a microfarad (mF). pF and nF are so tiny do not even look at them. With your size array voltage might not be a problem, but be sure to check that the voltage rating of the capacitor is less than whatever the array can make. Some people buy those solar yard lights, which seem to break often. You might be able to get some and use the contents for your project (pre-wired circuits).
Q:Charging batteries with a solar panel?
can I use a 2volt .5 amp solar panel on a 2 volt battery in a boat that i use for trolling motor and if I can can I leave it hooked up when using the trolling motor ? Plus how long would it take to charge a half drain battery with this panel??
Q:Solar panel question
The answer is actually quite complicated, but if you're planning on building just a very small system, most likely, the panel will be small and weak. In this case, connecting a panel that is 8 volts open circuit directly to a lead-acid battery is probably the most efficient way to charge. There are charge controllers that you can buy, some of which actively track the maximum power point for charging your battery. Unfortunately, those controllers might eat 5 or 0 watts, just to get you another few percent of charging efficiency. If your panel is only 50 watts in the first place, you can see that this is not a good deal. If you're getting serious panels (clue: price $500 each), then you may very well benefit from a charge controller with MPPT (max power point tracking). Lead-acid, either a flooded cell like your car battery, or AGM, are the standard for solar energy storage. Lithium ion is better in many ways, being less sensitive to temperature, state of discharge, and they are also lighter. Charging them is also more straightforward with the right circuitry. The problem is, they cost like $500 per kWh, compared with less than a tenth that price for lead-acid.
Q:Where can I get free solar panels?
If they're just to be used as an example, go around your neighborhood, and find a yard with solar yard lights. Then ask the owner whether you might borrow one or two. If they say no, move on and find another house. I'm pretty sure someone will say yes, after you explain what it's for. They will trust you, because you could have just stolen the lights, but instead asked. Option B is to have your parents take you to Fry's Electronics, and purchase a solar item, like a motion detector light, or even a standalone solar panel. As long as you don't mess up the box, you should be able to return it later for credit. But that's borderline dishonest, because you never intended to keep the merchandise.
