Q:Does a solar panel work on a cloudy day or a rainy day?
This Site Might Help You. RE: Does a solar panel work on a cloudy day or a rainy day? I've heard that solar panels have back-up batteries for when it is cloudy or rainy that day.. is this true?
Q:Solar Panel Question?
I like TBS0's answer, but 5KW isn't going to hack it. We don't live life on the average. If you turn on the oven, the dryer, the iron, a bunch of lights, and the TV, you are going to shut the system right down. You should not count on running everything with solar cells, but the most critical circuits. And you are lucky to have 25% of a day in optimum solar alignment for photocells. You need to think outside the Al Gore crazy box. Our modern way of life requires a lot of power! If you switched to coal or wood for cooking and heating and ironing, sunshine for drying clothes, heating the hot water heater, and for daytime lighting, then you could use the photocells for some lighting and the washing machine and anything electronic. You might stand a chance.
Q:how to know the voltage level of solar panel?
The voltage rating and current rating are part of the specifications for the panel. You will have them listed on the spec sheet. The voltage number is usually the open circuit voltage of the panel, the voltage with no load. The current number is the short circuit current of the panel. In use, you need special electronics, called a Maximum Power Tracker (MPT) controller, which adjust the load to get the most power from the panel, and adjust the voltage output via a DC-DC converter to the optimal conditions to charge the attached battery. how to take batteries as per solar wattage ? sorry, don't understand this.
Q:solar panel efficiency in space?
Solar panels on spacecraft are a lot more efficient than ones made for home use. That doesn't include the effect of the atmosphere.
Q:Solar panels on the roof?
Just had them installed on a development of 4 homes and they look goood! So far each user has free electricity during daytime for 3/4 of the year. If you live in a hot country - that's free A/C to keep you cool. The downside is that it is grid-tied so there is no storage, which means that if you use electricity to cook the evening meal - you don't get that free. What we advise to do instead is to make use of slow cookers that cook meals during the day - for FREE, and just serve it up in the evening as it keeps the heat. It would be more effective if you used storage radiators and heated hot water tanks for washing/bathing using it but this hasn't been added yet. It's free power all day - so what is there to complain about? The only catch I have found is that some power companies charge YOU if you export power to the grid - so just watch out for that, and design your system to avoid this if this applies, but most just don't pay anything - so you may as well use what you get.
Q:What to do with a solar panel?
Hey AJ, Tom is quite right, a panel that size is a great trickle charger at .2 amps. If you have a good sized 2 volt battery, like from a truck, or for a boat trolling motor (it should be at least 60 amp hours) you can hook it to the battery and it will charge it slowly anytime the sun shines. Don't worry about the voltage, most 2 volt nominal volt panels are wired for 8 - 9 volts, and if you hook them to a battery, the panel voltage comes right down to the batteries charging curve voltage anyway, they are designed for that. What you do need is a diode. A diode is an electrical check valve, allowing current to flow in one direction, but not the other. This will prevent the battery from discharging through the panel at night. Many panels today come with diodes inside the junction box on the back of the panel. If yours does not have any, go to Radio Shack, look for a 6 amp silicone diode, usually around75 cents. Put it in series between the panel and the battery, then, while you have a voltmeter hooked to the battery, connect the panel/diode to the battery and see if the voltage goes up slightly. If it does, you're all set. If not, turn the diode around and try it again. It has to be connected into the circuit the correct direction. Many people will state that you need a charge controller, but this is not necessary if your panels max current, ISC is less than 2% of your batterys amp hour capacity. In your case, if you have a 60 AH or larger battery, skip the controller. There is a great discussion about this in Richard Perez's book, I will list it below. If you want to learn more about these devices, there is a great magazine that gets into the nuts and bolts of renewable energy, it's called Home Power Magazine, the link is below. We started by hooking a slightly larger panel to some golf cart batteries 2 years ago, reading that magazine and going to some energy fairs. Today our home is completely powered by the wind and sun. Check it out sometime. Take care, Rudydoo
Q:Is it truE thet solar panels. . ?
It is a system, you can get a small scale panel that can do things like charge cel phones and ipods. The type of system I have installed on my home needs a converter that turns the dc current that is produced by the panels into ac current to run in my home. I don't have a battery system because I'm not off the grid. When I'm generating more electricity than I am using I sell it back to my utility and at night when I'm not gernerating any electricity I buy it back again. Basically my meter runs backwards durning the day and frontwards during the night.
Q:When I make a solar panel what kind...?
You can make your own solar and wind power for less than $200. You can your power bill by making your own solar panels. You can save thousands of dollars and go green at the same time. 93.9% of the energy that is consumed by US is NOT from renewable sources. The best choices when it comes to home power are solar and wind power. These count for only 0.2% of the energy that is consumed. You can generate your own energy and send it on the power grids. If you don't use all the energy you produce the power company will pay you.
Q:The voltage and power problems of solar panels
3, charge 12V battery when the power is really small, if it is a normal controller, then the equivalent of 18V voltage in the charge, probably 18 x (240 / 30.2) = 143w solar panels.
Q:What are the properties of Solar Panels?
American scientists have developed a new coating, which allows the solar cells to cool on its own, without relying on costly cooling and ventilation. Coating increases the output power and prolong the life of solar batteries .
