Q:Are solar panels only effective in places where there is an abundance of sunlight?
Solar panels generate power only during sunshine hours. But they only need sunshine, they don't like the heat, that comes along with the sunshine. So its a trade off, the places that have a lot of sun, also have a lot of heat, and places that do not have a lot of sun are not that hot. But you do need sunlight to run solar panels. There's a lot of tools available which can tell you how much power you are able to generate given your location.
Q:Question about solar panels?
Good question. Something to keep in mind is that modern solar electric works _alongside_ the grid, so you don't need to displace your entire 2300 kWh. The best financial return, if any, might come at a point where you generate only 500, 000, or 500 kWh per month. How many panels you need strongly depends on your location. Speaking for the location of my house in San Jose, Ca, that amount of usage would be about a 2 kW array, and if you divide 60 into that, you get 200 panels. In a perfect location, you would need slightly less, in a northern state, you might need double that. If this was a real project, you would probably not use 60-watt panels. The choice of panels is not simply a matter of getting enough watts. 2 kW is a large system today for residential. The usual advice is to go for energy efficiency first, then consider solar after the usage is down.
Q:how many 45 watt solar panels would I need?
Lets say, for a simple approximation, that the 45 watt panel produces 45 watts /3 of the time and nothing the rest of the time. Each day, this will produce 8 hours times 45 watts = 360 watt hours. Also assume the battery charge controller and inverter waste half of that power, leaving 80 watt hours per day. If you use compact fluorescent lamps, that would allow you to burn 80 watts worth for an hour every day, or 90 watts for 2 hours, etc. That is a lot of light for a shed. You might consider using much less efficient tungsten filament lamps, but eliminate the inverter and choose low voltage (automotive) lamps that can run directly across the battery and lower the total cost, but give you only about half the light times time. The main advantage of the inverter might be that it would allow you to use small power tools or appliances in the shed. -- Regards, John Popelish
Q:SunPower Solar Panels?
Power from solar panels depends upon its proper installation and the brightness of the Sun.
Q:Do you know that China is the largest producer of solar panels in the world?
Solar voltaic panels are not 30,000 dollars each, a good panel, 24.4Vmp, times 95 watts, is about 900 dollars. Solar electric generation, makes sense, not because of the myth that the energy transmission companies 'buy' the energy you produce in excess (energy companies, zero out the balance at the end of the year, so that it only makes sense to design a system that equals your needs, not exceeds them). Solar electrical generation, is the future of energy freedom, but the powers that be, do not have yours' and my economic freedom in their portfolio. They are actively pursuing the globalization, to push down the working class, to the 'post industrial age', where the working classes, can once again, be relegated to serfdom, while the super rich, drink DOM, and watch us toil in the sun.
Q:Maintenance of Solar Panel?
I don't know if the guy is right about cells burning out if they are covered. You should look on the Internet for insolation tables for your area to see the effective hours of sunlight. Then guesstimate the percentage of time the panels will be shaded. Those trees may make the solar thing a poor idea. He is right about the trees reducing you efficiency. If a panel is shaded about 0 percent, its output drops to close to zero. My panels are five years old, and I have washed them twice. There as been no noticeable dropoff in output.
Q:How many solar panels do we need to power the US?
Annual power consumption in the US is approximately .2*0^5 Watt-hours. The average solar panel can generate 80W continuously. We can break up the calculation into parts: .2*0^5 Watt-hours per year 925 hours per year .3*0^ continuous watts 80W per panel 64383566 panels 000 sq. inches average solar panel area 650 million square miles (!!!) To give you a better idea, the total surfacre area of the United States of America is 3 million square miles. The surface of the earth is 96 million square miles. Not even 3 planets full of solar panels would be enough. Maybe it is easier for people to start using electricity more responsibly?
Q:Solar panel cable setup?
How long is the run? 2 gauge is a good choice for runs up to 25 feet at 20 watts, if you are much further in your run, move to 0 gauge to reduce resistance of the wire itself in the circuit. Otherwise refer to the prevailing electrical code of your local unit government. This is a must if you plan to maintain insurance. At lower voltage, a little resistance means a lot. 4 gauge might be okay for 20 VAC, but the voltage drop on a low voltage system from resistance of the wire itself is measurable at 20 feet. It is the difference between a light fixture working or not. If you are planning on adding additional panels in the future, you can get terminal buss with screw hold downs at various vendors like Mouser or Digi key. Each panel can be on it's own screw, while the buss is common on the other side of the connection. one for the positive and one for the negative.
Q:where can i get a small solar panel to power an outdoor water pump?
You will need more than a small solar panel to run a pump continuously, unless you don't mind that the pump only comes on during the day while the sun is out. st you need to know what the power demands are of the pump in question. Not only do you need to know the rate of the power draw from the pump, but you will also have to calculate how much power the pump will draw from your solar system every day. You will have to factor in that the sun doesn't shine brightly every day, of course there's also night, so you will need a storage battery, charging system to go along with your solar panel. Now most pumps like the one you described are 20vac. Most solar panels, the batteries, the chargers are 2vdc. In order to get 20vac you will need an inverter. Once again, you will have to make sure that the inverter you get can handle the demands of the pump. A solar system that actually works for you takes some carefull planning, it's not something that you can just hang from a tree. None of what I just descibed will be inexpensive by my definition, so if it were me, I'd dig a trench across the driveway, install some direct bury cable on a GFCI circuit out of my main power panel save a bundle.
Q:Computation of Solar panel requirement?
The power output of a solar panel uses a formula to determine kilowatts produced per hour per square meter per day. This calculation is important because, if you plan to install a solar power system for your home, you will want to know how many solar panels will be needed. To calculate solar power requirements correctly, you need to gather the data that is needed for the calculation. First you have to find the average amount of solar radiation available for your area. You can use a solar radiation chart. This can range from a 4 to a 7 depending on the area you live in. Write the number down on a piece of paper and indicate it with the letters RA. Next is determine the amount of electricity that you use daily. Add the kilowatt-hours used per month from your utility bill. Multiply this number by ,000 to get the watt hours in a month. Divide the total by 30 for the amount of electricity you use daily. Write this number down and indicate it with the letters DE. Determine the percentage of your home that you want to power with the solar power system. Write this number down and indicate it with the letter P. Determine the system inefficiency factor for the solar power system. You should be able to find this on the brochure for the system or from the manufacturer's web site. Write this number down and indicate it by the letter I. Determine the power or yield that is required for your home. Use the equation P = I x (DE x P) / RA to find the power requirements in kWh. Divide the number from Step 5 by the peak wattage for a single solar panel to determine the number of panels you will need for your home. Goodluck! :)
