Solar Energy Advantages Disadvantages

This page is a review of the technological and economical of solar energy advantages disadvantages. The advantages get a lot of publicity, to balance the picture the disadvantages and limitations are highlighted.

Advantages of Solar Energy

In this section I will discuss the solar energy advantages, disadvantages will be discussed in the next paragraph. The advantages are:

  • Residential solar power generators are silent.
  • Photovoltaic generating systems have no moving part therefore they require a very low maintenance effort, they are reliable and the life expectancy of solar generators can exceed 20 years.
  • Domestic solar electricity generation systems do not emit polluting gases and do not produce carbon dioxide. It is expected (we already see the initiatives in Europe) that taxes will be imposed on carbon dioxide emissions. You can preempt these future carbon dioxide taxes by installing a residential solar power system and a domestic solar powered hot water heater.
  • Once the initial investment is covered, electricity supply from the solar generator is effectively free of charge. Based on the last decade trend and with the political turmoil in the Middle East, it is expected that utility electricity will be more and more expensive in the future to reflect the higher prices of fuel; therefore securing a free of charge electricity during the expected future escalation of energy prices is really a benefit
