SOLAR PANEL Kilowatts- how many kilowatts does a 1x1 sq meter photovaltaic panel create?
Question:
Answer:
It depends on the efficiency of the panels as well as the anxillary connections.
i.e. The inverter (to produce AC from DC)
Battery system (if not used to feed into grid)
Other control functions (for disconnection and monitoriny).
Typical efficiency of system is around 10 to 12 %
If the sunlight you recieve is around 1000W/m2, you will get around 100 to 120 W of power.
However, research are being done to increase this efficiency. Hopefully, we get them soon!
Depends on the panel construction; 100 watts would be typical with direct sun at noon on a clear day.
You need more information, too many variables that greatly influence the answer
it depends on the panels efficency and its location. The amount of energy hitting the surface of the earth is variable from place to place and season to season.
Normally the good PV panels give an output of 15W per Sq.Foot,
1 meter = 3.28 Ft
1Sq mt = 10.76 SqFt
Watta output = 10.76 x 15 = 161 Watts approximately
This is under peak sunlight .
There are a great many different solar electric panels around and no two would give the same output. It depends on the efficiency of the panel - how many cells it has and how efficient each of them is. Light intensity also affects output. They don't work in the dark and as the sunlight gets weaker so the output drops.
Research different brands and you'll see a vast difference in output for a given size, and these are only the "claimed" figures at optimum performance.
The sun produces about 1kw of energy on 1m x 1m but the photovoltaic cells are not very efficient 6% for cheap ones to 12% for good ones. So you will get only 60w for the 6% and only twice that for the good ones.
The other drawback is you only get 1kw or more for part of the year and only in the middle of the day, hardly the time you need most power so you would need a way of storing the electricity. Batteries is the normal way but charging a battery is also inefficient so you loose even more power.
In research laboratories they have managed to get some cells to over 40%, when commercial cells get to this level of efficiency then it will be a very interesting idea.
