Q:what is a solar panel?
A panel that is attached to the top of a roof of a house that converts the suns rays into electrical energy that can be harnessed and used to power appliances, light rooms etc. through silicon particles.
Q:Solar Panel watts needed?
With you up to solar panel, then things go downhill. Your Water pump will be rated at gal/hr but how about the air pump? 600watt LED? What you need to know in order to select your solar panel is how much current you will be draining. You can work this out if you know how much power and how long they need to run. Please, a bit more information (that is relevant!).
Q:Efficiency of solar panels?
The Sunforce 50048 60-Watt solar charging kit is designed as an “out of the box” solution to your solar power needs.The Sunforce 50048 60-Watt Solar Charging Kit gives you several more reasons to love the sun.It provides the power you need, while helping you save money and protect the environment. This kit is ideal for cabins, recreational vehicles, remote power, back-up power, and 2-volt battery charging. It comes with everything you need to start producing up to 60 Watts/4 Amps of clean, free power in all weather conditions.
Q:How much would solar panels cost for these?
They would cost quite a bit but the user would likely be eligible for some energy credits from the power company and their cell phone carrier which would bring down the costs
Q:How to setup my home on Solar Panel?
good okorder.com lots of good ideas there
Q:I have a 6v solar panel , but a 3v dc motor doesn't run with that!!!!?
It may be that the power output of your solar panel is not enough to drive the DC motor. It is producing up to 6 volts but it may not be producing many milliamps. LEDs need very little power to work but DC motors often need quite a high current to get them turning. If you can run several solar panels in parallel, you can probably increase the available current. Alternatively, can you expose the existing panel to much more light so as to get it to work at its maximum output? That might work. Good luck with your science exhibition.
Q:How efficient are solar panels?
Solar okorder.com
Q:What is the main material for making solar panels?
If you make your own, in addition to buying silicon also need to buy for the packaging of silicon photovoltaic glass and EVA film.
Q:Solar Battery System?
A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
