Somewhere around 10 years. But it's not a simple calculation. You need to take into account the interest you would have earned if you had saved the money instead of buying solar panels.
In brief energy payback time for solar panels is how long does a Photovoltaic system have to operate to recover the energy and associated generation of pollution and CO2-that went into making the system.
If you install the panels yourself, you can do the installation for about $3.75 a watt plus the cost of inverters and power switching equipment. Payback time on my system is roughly twenty five years, assuming power buy back at $0.10 a KWH.
Payback Time was created in 2000.
Payback is usually a specified amount at a specified time. If money is to be gained at an average rate of return, the amount of the return could fluctuate due to inflation or interest rates.
the average of the mean solar time for a particular time zone
payback period , it is to pay your period on time jajajaja
At the time, the Solar System was believed to be fake. People believed only Earth was real.
If we do not consider the rebates that some countries offer on solar panels, the payback normally runs between 20 and 25 years. The long payback though ignores the increased benefits to the planet and the possibility of increased electric costs over that time period. Panels will also degrade with time. Warmer climates may see a slightly longer payback period, due to the decreased performance of solar panels. I have several panels on my home and they actually produce more power in the winter months, despite the shorter daylight periods, due to the cooler temperatures
Payback Time - 2008 was released on: USA: 15 May 2008
Because solar panels/ cells which collect the solar energy are expensive also they are very unreliable when the sun is not out. .Payback time is expensive .time consuming .It does not produce that much power which we need. . it does not produce energy in night. . The amount of energy obtained changes depending on the climate.
Simple payback method do not care about the time-value of money principle while discounted payback period do take care of this principle in calculation.
Something is meant by the payback period. It is the length of time taken to recover the cost of an investment. This is what is meant by the payback period.
