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.

Why did India will not use the solar energy?
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.
What are bad things about solar power?
Its expensive to build, or put solar panels on house roofs. It has a long payback time. Solar panels are ugly and big. The sun isnt always out, especially in places like UK, where as Spain it would be perfect.
How long does it take for a solar panel to pay for itself?
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
What is the average payback time for a solar pv system?
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.
Are ultraviolet rays not a harmful disadvantage of solar energy?
Ultraviolet rays are generally considered a harmful disadvantage of solar energy. These rays cause damage to the solar panels over an extended period of time.
Why does the Mars rover have solar panels?
As the Mars rover would be on the planet for a long time it would have to use solar energy alone to move around.
How does solar hot water heating save energy?
this saves energy because solar panels are used that absorb the suns energy for long periods of time. and since energy is needed for hot water it is given off by the sun.
What does energy payback time mean?
You need energy to make a solar panel. Put it on your roof and see how long it takes to generate that same amount of energy. That's the energy payback time.Energy payback time means the length of time that a solar panel (or other device) will take to produce that same amount of energy that was used to make it.This is used with renewable and non- renewable energy solutions to describe how long it takes for the device to generate the amount of energy that it took to make it in the first place. It can also be used to measure the amount of energy your save by using an energy efficient device.payback time = total costs/ total saving or money made or energy produced per year. You can thing of payback time in both economic and energy terms - how long it takes to pay back in money terms the costs, or thinking about the costs being the energy needed to produce the device.A wind turbine's energy payback time is about four months. The estimated life of a wind turbine is about 25 years.Devices like:solar panelswind turbineswater turbinesgeothermal power plantsbiofuel plantsbiomass power plantswave and tide power plants

How many solar energy companies in Ontario Canada?
Solar energy is not a practical idea for Canadians as the average full sunlight hitting most of Canada is too short. There is also a maintenance issue with the snow and ice buildups. The payback time for solar in most areas is decades long. In Canada this would increase. Solar panels have a fairly short life span. Twenty years is considered a very old panel and through it's useful life span. It would be environmentally irresponsible to use solar voltaics in virtually all of Canada.
What is the problem with solar energy?
Solar energy, while being quite useful, can also have it's own problems. For example, how does solar energy work if you occupy a place that rains most of the time? The sun is never out so, no solar-power. Furthermore, the rate of efficiency with solar panels is only 40%, is it worth all the money that is paid for them?
Is solar panel an expensive or cheap method to use?
It depends. If you only use solar panels for a little bit of time they seem very expensive but if you use solar panels for years and years they seem less expensive. If the prices stay the same they do now, in 15 years solar panels would still cost a bit more than regular energy but the keyword is if. Since there will be more demand in energy and less supply of fossil fuels the prices of those will probably rise. Also since there will be more demand for energy, solar panels will probably cost more to install in the future than now.
