- Q:How much candle lights is required to operate a 205 watt solar panel?
- That's hard to tell. A solar panel produces somewhere between 7 and 0W per square foot under sunlight exposure. You should calculate the light intensity of sunlight, and then calculate the light intensity of a candle (You'll have to look that up in some physics book or the internet) and then just multiply the number of candles until you match the intensity of sunlight. Realistically, you would need so many candles that you wouldn't be able to fit them in front of the solar panels, assuming you don't end up with a huge fireball.
- Q:who would win in this battle?
- Trees for sure. Their already plotting the overthrow of humans.
- 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:i am asking about the solar panels?
- First of all, make sure that you are taking readings in the dark (with the solar panel indoors and covered). 0.433 is a reasonable forward voltage for a Schottky diode. Ideally, it diode should read open one way (possibly OL for your meter), and 0.4 the other way. If it's reading OL both ways, the diode is bad. You can either unsolder it or cut it out and verify that it is bad.
- Q:solar panel webcam?
- Q:Can you overload solar panels with too much light?
- A photovoltaic cell will only be 'sensitive' to a band of radiation...and would probably not even 'see' the energy from a heat lamp. So, no, the solar panel would not be 'overworked' if somehow you could put 2 or 3 suns in the sky at once. It would simply ignore, so to speak, the photons that it didn't need. But, the heat from the heat lamp, or the extra photons, would eventually heat up the glass and the plastic the thing is made of, and it would fail prematurely.
- Q:Solar Panel Current=Battery Current+Load Current?
- Current rating of a piece of supply equipment is the maximum current that can be supplied. you may have the capacity to supply 8.75 amps total but your load may draw a lot less than that. like if you fill your cup from a bottle. the bottle may hold 5 gallons but you only use one quarter of a pint to fill the cup. I hope that makes some kind of sense.
- Q:How much does it cost to install Solar Panels?
- The North American Board of Certified Energy Practitioners (NABCEP) is the “gold standard” for PV and solar heating installation certification. Cost vary on the size and difficulty of the project. The price of the panels are dropping and technology is getting better. A rough rule of thumb estimate would be $3 per watt for all the hardware and then double that to cover labor and overhead (insurance, permits, gas for the truck etc) Solar thermal has a faster payback than PV. The panels themselves go up fairly quickly. Installing roof mount attachments can take some time. This is also one of the points of liability. If done improperly the roof may leak and cause more damage than the profits on that job could pay for. There are a number of kits and pre-bundled packages available. You might try installing one of those on a friendly first. Make it a weekend project for yourself or on a friend or relatives house.
- Q:How does a solar panel charge controller work for batteries?
- The battery is probably 2v 7amp-hour, not 7 amp. 7amp-hour is basically just how big the battery is. You can charge that battery with as little current as you want, it'll just take longer. The 7 amp-hour tells you that it'll take a long time to charge. 7 amp-hour means it can discharge 7 amps for hour. If you were charging it at 7 amps, it would take hours to charge, but I don't recommend that. You could charge it at .5 amps for 4 hours or .25 amps for 28 hours. The smaller the current, the longer it will take, but it will get there eventually assuming your voltage is high enough (which it should be with the charge controller).
- Q:Can a solar panel be used as a NiCd cordless tool battery charger?
- Your 5W solar panel has to put out about 5 volts or higher to charge a 2 volt battery. 5 watts at 5 volts is only 0.3 amps, which is only enough to handle the internal leakage inside a large battery, plus a bit. If you have a 00 amp-hour battery, that panel would take 300 hours of bright sunlight to charge it. But I do agree that it will keep the truck battery charged as long as it gets sun. Make sure you put a diode in series between the panel and the battery to prevent the battery from discharging through the panel when the sun goes behind a cloud. I'd be worried that if you charged the 8 volt battery frequently, the panel would not be able to replace the lost charge, and your 2 volt battery would wind up discharged. That 8 volt battery is .2 amp-hrs (if I got the correct one). That is 27 watt-hours. Allowing for losses, you car battery will have to deliver over 30 watt hours to charge it. Your solar panel will take over 6 hours of bright sun to make up that difference. That is over 24 hours this time of year. So if you recharged it more than once every 2 days, you will lose charge in the truck battery. .
