When I read that solar systems only transforms %5-%15 of sunlight energy to actual energy!?
Answer:
This is already calculated in to the size of the collector. A 10% collector that is rated at 100w is being hit with 1000w of light. But here is the key thing you need to think of. Not all locations get hit with the same amount of light. The earth is a curved surface and depending on where you live you will either get more or less light per hour. Some locations also have more clouds than others and clouds change the amount of power generated by a more than you might think. There are websites that will give you numbers for major cities. Some cities get little sun energy which would greatly change the amount of your power. So you might have a 100w cell but because of clouds and your position on the earth you might only be able to get a fraction of that over time.
It is already calculated. Of course there are assumptions like amount of light incidence on the panel.
You will get 1 watt in normal use.
NOpe it's already calculated be-4 it's not only %5-%15 but it's has their Efficiency electricity which I think will change all the time, it's really ignoring though
Already calculated.
the 1kW is the max. output rating of the pannel.
5% efficiency means that to get that 1kW out there has to be 20kW of solar energy (light&heat) falling on the collector.
The 1KW panel(S) should produce 1KW output maximum. This is usually under perfect conditions which can seldom be achieved for any significant amount of time. The sun has to be at exactly the correct angle. The panels are new (they degrade with time). The covers are clean. The batteries or power receiver has to be low enough to allow max amperage flow.
lol already calculated...1kw is the amount it produces over peak sun hours. you will get *4 that amount for 4 peak sun hours.
The 5-15% figure is how efficent your panels are rated at and how much they would cover in area over your roof.
That figure is maily talking about area efficency.
So this is how you would work out a systems area size.
1kwh * per M square of sunlight hit the earths surface per square meter...
Therefore 5-15% of that will be used by your 1kw system providing you 50-150watt per square meter with a total of 1kw......
No, it means that your solar panel will generate 1Kw on average (sun conditions change). If the solar material was 100% efficient, then the same panel would generate a whole lot more. The efficiency rating is just how much of the potential energy striking the panel gets converted. The highest efficiency solar cells generate between 20 and 40%, but so far this level of result has only been achieved with very expensive custom made cells under laboratory condiditions.
