Q:Mono-crystalline or poly-crystalline solar panel?
All solar photovoltaics drop in efficiencies with higher temperatures but it isn't the 45+ C you have to worry about but rather the heat from the sunlight striking the panels. There are hybrid systems which passes water in pipes attached to the back of the solar panels to cool the panels and preheat the water for solar thermal collectors. The difference between mono-crystalline and poly-crystalline are that mono-crystalline are more efficient and more costly to make.
Q:Which solar panel should I choose?
the last one has highest wattage. that will bring down the total number of panels you need to meet 40 KW. you probably need 220 panels
Q:What does solar panel power?
Solar Panels have a large range of prices. You can get a 0W panel for approx. $00 to 200W solar panels at $2000 and beyond. You would want to figure out how much electric heat you use. Then from there, figure out how many solar panels it would take to compensate that. If you need help figuring this out, I would suggest reading a Solar Panel How to Guide and/or looking at a Solar Panel Forum. Best of luck to you!
Q:What is the most efficient solar panel?
Most Solar Panels are roughtly 6% efficient. Since the sun gives out about 366 watts per square meter, a good panel would be 200+ W/square meter. If you want to save a bunch of money, I suggest you have a look at this tutorial I'm linking. The guy explains how you can assemble your panel yourself. It's far easier than I first thought !
Q:Why are solar panels placed on the roof of houses?
The roof is the most popular location for panels, I'd imagine because: ) The space is not otherwise being used. Panels in the yard would take up play space, or shade the garden or lawn. 2) The roof is usually more free from shadows because it's high up. Something low to the ground could more easily be shaded by trees, fences, or nearby buildings. 3) The roof often has a built-in tilt that is more ideal for panels. Take a good look at your roof, especially if there is a south-facing side. The roof could be bigger than you think. Only 0% of our roof area is dedicated to solar panels, and that keeps up with our yearly electrical usage.
Q:Anyone have or know someone who has solar panels installed in their home? Is it worth getting?
Our neighbor has solar paneling, and he absolutely LOVES it! It is pretty much the same as having electricity, just better for the environment, and your electricity bill goes down to only about $7 a month!
Q:how many solar panels do I need for my house if in average i consume 880 kwh?
how many solar panels do I need for my house if in average I consume 880 kwh
Q:Where are solar panels used?
Solar panels can be used anywhere in the world. The only requirement is that there is sufficient sunlight to power the solar panels and in many developing countries, solar energy is used to heat water.
Q:what is one benifit in a solar panel?
In the UK, the only real benefit comes from the subsidies given to owners of solar panels. I believe the same is true elsewhere in the world. I suppose smugness might be a benefit though it is not justified.
Q:Opinions on Solar Panels?
I have a boat in a sunny place and four 80 watt panels. These will run my fridge Tv and a few LED's. I still have to run my engine for hot water and washing machine. My Batteries only last a few years and are a real pain. I go on the mains when I can to get the batteries topped up. The panels are ok if there is nothing else, they are not the answer to the future of energy supply. There is also the moral aspect of the feed in tariff. For the rich to load their electricity bill onto the less well off is not acceptable and those panels on the roof tell all your neighbors that you are doing it. That will show a greedy selfish attitude. If they are any good why don't the power companies buy them and save buying coal?
