Q:I have a 6v solar panel , but a 3v dc motor doesn't run with that!!!!?
It may well be that the motor demands more *current* than the panel can provide. Can you measure the voltage from the panel with the LEDs across it, and then with the motor across it? I suspect that you'll find that the motor makes the voltage collapse.
Q:How to setup my home on Solar Panel?
good okorder.com lots of good ideas there
Q:how many solar panels needed for Heater and AC?
There are many, upon many variations of equipment needed for a complete solar home. I would call several contractors in your area that deals with it and get estimates. You have to look at what your wattage diet is at your home. How many watts are you using for your AC and heat. Which can vary by age, efficiency, insulation of home, etc. Look at your electric bill for a normal summer month and a normal winter month, then estimate your heating and cooling (Sometimes can be as much as 70% of the bill). You will see on your bill your toal kilowatt hours. ( Kilowat = 000 Watts) Solar systems can start as low as $2.00/watt, but can rapidly approach $20.00/watt depending on the difficulty of application etc.... Here is the great thing, in many areas of the country there may be rebates from the county or state. And what you don't use can be fed back into the grid, and you get paid for it. But as always - Call a quailified contractor and get the right system for your home.
Q:Solar panels.......Earning potential.?
it depends on your solar panel, but you can sure supply most if all of your electronics and electric stuff in your house on a sunny day. If you want to know exactly how much power it supplies and how much $$ you can save you simply have to calculate how much power your home consumes per day/month. I know of people totally reliable on solar power for their home and I too will put solar panels on my home one day.
Q:Does a solar panel work on a cloudy day or a rainy day?
Yes, they work but if it's real rainy they won't work as well. I don't know much about Solar Panels but I do have them in my home, and they work amazing! Once in a while if it's pouring rain, they won't work AS well but still work! I If you really want a good answer, the company I used was actually very helpful and knowledgeable. I'm sure they wouldn't mind to answer some q's! If your interested -- 866-276-7222
Q:Solar Energy Panels, a good idea?
The panels are relatively easy to install. The batteries and the inverter tend to be heavy and you will need many people or mechanical assistance. You are talking about high current DC thus if you touch the wrong wires it's CC (Cancel Christmas - Rescue Squad Term). You also also dealing with lead acid batteries so they need to be well ventilated or we have another CC situation. Should you have a short, the batteries will overheat and explode projecting sulfuric acid... And the best part is when all is said and done, you are only paying twice to three times the cost for the electric over the life of the system as compared to buying the electric from the power company.
Q:Will my 8watt solar panel charge a car battery and how fast?
8w will be .5 amps or so.That would charge a .5 amp battery in an hour.scale that up to whatever your battery amp-age is and you will have an idea.But given that car power is upwards of 40 amp/hour,your looking at 60 hours+ for a full charge on small battery.I run a 400w inverter for emergency lights and tv (get the occasional power cuts)from an old truck battery with big amps and charge it with an optimate,but in doing so I found that I had to run a amp check on power draw to find the lowest use lights.and tv,Some of the so called low power consumption compact fluorecents had widely variable draws,after testing one was found that drew .68 amp and I chose the lowest mesured tv amperage draw.not exactly an answer to your qu,but end use is the same.Running the lamp only I eventually gave up checking on the drain after about 30 hours and now just periodicaly charge the battery.Rounding off.tv draw maybe 3 amps for a small set and watched for say 6 hours would be 8 amps drawn.that would need -2 hours on your proposed set up in ideal conditions.I have kept the figures rough because there is always losses in any system .so it comes down to how much tv you watch and how much the sun shines
Q:Do they make solar panels like this?
Solar panels only put out electricity when they are in the sunlight. If you need electricity after peak solar hours, you will need a battery storage system or a connection to the grid. You can run a DC device directly off of solar panels if the device uses the same voltage and amperage that the panel puts out. Your 600W lights use a ballast that takes AC current and will not work with the typical panel. Also, a 600W light will take at least 3 high output/high efficiency panels to run, and you will need more than that if you want to store energy in batteries. You are talking at least 60 sq. ft. of solar on your roof. Aside from the power you need, you are also asking for an AC current, while most solar panels put out a DC current. This is what inverters are for. There are some newer panels that output AC, but you are still talking about a lot of PV to power your needs.
Q:Solar panel question..?
Little solar panels on lights are very low power. The battery in one such may be 0.5 Amp-hours and .2 V ; it may be different but it should be marked on the panel/battery/manual. An outlet in your house is designed to run on 20 V (typically in N. Am.) and they run on alternating current (AC) whereas the panel generates direct current (DC). (If you don't know the difference, do not worry to much but just understand that they are not directly compatible.) You therefore need an inverter to change DC to AC (and lose some although inverters are now very efficient). But the amount of power generated by those panels is still very small. That is why solar lights are low power (just a few watts in most cases). To make things even more irritating, phone chargers do not work off 20 V AC as you are charging the battery and need a low voltage DC -- which is what the solar panel is giving you. It is almost certain that the voltage from the panel will be less than the voltage required for the phone. The charger is mostly cable but there is a black box incorporated and it should say what the voltage and current output are (the input will be 20V). So you should be able to overcome this not by hooking up the panel to a 20V outlet and then plugging the charger in but by hooking up the panel to the phone directly if you can get enough voltage out of the solar panel (or hook up several) and if you fashion a connection device. They already make them -- solar battery chargers and I am sure you can enter that into a search engine and find loads. Typically the panel alone is much more than a solar light -- which shows the relative power requirements.
Q:Solar Panel Watts?? help!?
This is not a precise analogy, but think of it this way: Volts is the pressure of the water in a pipe. Amps is the gallons per minute that come out. Watts is how much water you have after a certain length of time the pipe is open. a 200 watt solar panel under ideal conditions ( bright daylight between , say 0 am and 2 pm, held exactly flat to the sun ) will produce enough energy to run 2 00 watt light bulbs. You hardly ever have perfect bright sunlight; the length of the day varies during the year, and the angle of the panel to the sun changes from hour to hour; all this leads to a typical home in the US /Europe having only about 4 hours a day of maximum solar available. So, your 200 watt panel would give you 800 watts a day, enough to run one 00 watt light bulb for 8 hours If you are trying to run a house off solar, there are unfortunately other things needed between the panels and the lights / appliances; inverters, batteries, controllers sand each one eats up a little energy so you may get only 75 useful watts. See why more homes don't have panels? The other poster who said $30-50,000 to completely run a home on panels is about right.
