Q:Solar Panels!!???!!!?
Solar Power. There is no denying it, solar power works. Not only is it energy efficient, it is also safe and extremely clean. Whether it may be for a home, business or a community, there are no limits to the energy that the best solar panels are able to offer.It is a guarantee that once this medium is applied, you would easily slash your greenhouse gas emissions and electricity bill.
Q:How do you make a homemade solar panel?
Did okorder.com/ . Possibly this could immediately instruct each and every one!
Q:How can I run my house purely off of solar panels?
There are a variety of factors that come into play in order for you to calculate the answer. Additionally, there are a number of variables that can make the answer change over time. The number of solar panels you need to install to power your home will depend upon your electric power demands, the weather in your area, the angle of your roof, shade issues from nearby trees or buildings and the size of the cells. All of these factors are important and must be built into your calculations so that you can create the best solution for your home and your future needs.
Q:Need help with building a project involving solar panels?
Solar panels are designed to be used to recharge a battery or series of batteries, not for direct power. That is the inherent weakness of solar systems. The only way to have it work in low light conditions if to have several cells wired in series and have a voltage regulator to limit the amount of voltage that can be supplied. Other than that, add a battery and a charging circuit that the cell would supply power to.
Q:Solar panel experiment ?

Q:Solar Panels in Abu Dhabi, UAE?
I know where in Dubai , just go to Naif road where they sell the satellite equipment , there are a couple of shops that sell all kind of solar panels and dish equipment stuff. Sorry can't remember the name, But it is right in front of the paid parking lot (the private not public one).
Q:Any help financially to buy solar panels?
I don't believe that there is any help yet.
Q:How many Solar panels?
Quite a bit to run 480 volts @ 50 amps. Ohms law will give you the basic level your looking for but also you need to consider power storage ... Conversions .... Start up power vs running power levels ... it can be done but this is a bigger system then what I need so I cant just give you an number your panels will be rated in wattage and amperage you then take that power and put it in storage (battery) to inverter system (mine is 20 volt) you will need to have a 480 inverter for your power level. good luck hope I was of some help.
