What are the disadvantage of the solar energy?

Answer 1

what are disadvantages of solar distillation

Answer 2

Disadvantages are:

• The biggest disadvantage to solar energy is the fact that the sun has to be shining to take full advantage of it. Since the sun only shines about half of the time, the other time is totally unproductive. There are also a number of areas in the world that don't have many sunny days in a year. Only areas of the world with lots of sunlight are suitable for solar power generation
• No energy at night time is another disadvantage of solar energy. There is no solar energy to be collected which means you'll have to have adequate battery backup to get you through the nights.
• The other big disadvantage is the initial investment that is required to buy solar panels. This disadvantage is offset by a lot through government incentives in the form of tax credits and rebates. Another thing that offsets this initial cost is the value of your home increases dramatically. My home appraised for an additional $70,000 following the installation of my system. A solar PV system costs a lot of money, but this is "expensive" because we are used to paying a small amount for electricity from utility companies.
• A solar thermal system uses electricity to run the pump, but the net effect is so largely positive that it is safe to say that this doesn't really count as a "con"
• The biggest "con" is that if people invest money in them they can have a tendency to use energy more freely rather than continuing to try and be economical with resources as they feel they have "done their bit
• Solar cars are not currently a viable option, although advancements are being made. They may or may not ever be a good option.

Solar panels are fragile and very expensive (they pay off in12 years).
