Advantages and Disadvantages of using solar panels?

We Answered:

Solar energy is a renewable energy resource and there are no fuel costs. No harmful polluting gases are produced.

Disadvantages
Solar cells are expensive and inefficient, so the cost of their electricity is high.
Solar panels may only produce very hot water in very sunny climates, and in cooler areas may need to be supplemented with a conventional boiler.
Although warm water can be produced even on cloudy days, neither solar cells nor solar panels work at night.

Explain the advantages and disadvantages of installing solar panels on your house.?

We Answered:

Advantages - fights global warming, saves having to run a power line to a remote house.

Disadvantages - more expensive (not counting the line) than just using the power plant.

They're mainly used by well off people who don't mind spending money to help the environment, and people who don't want to pay for running a line to a remote house in the country.
