Q:solar panels, wattage?
The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.
Q:thermodynamic question that includes heating water with solar panels?
Good points. I'm new to the solar energy world, but solar just makes sense. Who wouldn't want to make it work? The more I learn the more I think its a great alternative to some of the energy we use. This info really helps.
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:what is solar panel? full description needed?
Solar panels are devices that convert light into electricity. They are called solar panels because most of the time, the most powerful source of light available is the Sun, called Sol by astronomers. Some scientists call them photovoltaics which means, basically, light-electricity. A solar panel is a collection of solar cells. Lots of small solar cells spread over a large area can work together to provide enough power to be useful. The more light that hits a cell, the more electricity it produces, so spacecraft are usually designed with solar panels that can always be pointed at the Sun even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going. DS's solar cells are even more efficient than regular solar panels made for satellites because they use solar concentrators.
Q:Does anyone know a good company to buy solar panels from?
a few months ago there was an article in pop sci about a company that has started to make solar panels at a fraction of the cost of what they used to be by using a printing style process instead of glass panel style they should hit the mass market soon that would be the best bet for a starting point to beat out price problems to allow a competitive edge they also had a article for low wind high power residential windmills for that could help in the alternative fuel push
Q:how much energy does a 70x70 sq ft area of solar panels collect?
Considering capital outlays, such a system might never recover its initial investment. That's why we don't see such small photovoltaic plants popping up around the country - the economic case isn't there. One of the problems is that you would have to sell your electricity wholesale, at a ridiculously low price like 2 cents / kWh. If you were displacing electricity that you would otherwise use, then the financial case is different. Retail electricity could be 20 cents / kWh, 0 times as much, and you could get your money back over time, and start to make a profit. I've assumed you're in the US, with no special feed-in tarrifs. If you're in a country with a premium rate for solar-generated electricity, the business case could be very different.
Q:A Question about Solar panels?
I am sure someone can tall you.
Q:Solar panels and your opinion?
Regarding okorder.com/.. . In Hawaii, solar is going in like crazy, with long backlogs for installation. If it will be a long time until you retire, then there is no rush. The price of technology tends to go down with time, and in fact, solar panels today are less than half the price of what they cost us in 2006. Also, who knows where you'll be living when you retire? If it's Honolulu, the place may already have solar panels. In the woods of the Upper Peninsula of Michigan, it might never be worth it (but look into wind, there).
Q:How does a solar panel charge controller work for batteries?
7 Amp Solar Charge Controller
Q:Connecting solar panel help?
never hook up solar panels in series, you reduce the total power produced, and may hurt them, only voltage out, never voltage in. Don't forget to vote for best answer!
