Solar Energy Facts – Advantages and Disadvantages

Some solar energy facts that will help you know better about how to make better use of different alternative energy sources.

The sun beams enough energy on the Earth to satisfy worldwide energy needs. Solar energy is the technology used to convert sun’s energy and make it useable. It can be used with restorable solar technologies to replace energy systems that consume fossil fuels, thus help reduce harmful release into the atmosphere helping reduce greenhouse effect. Today, solar energy facts are important to know as they help us in using the resources in a better way.

Solar Energy Facts

Most of us are familiar with solar panels, found on handheld calculators, rooftops and spacecraft. The cells are made of semiconductor materials. When sunrays fall on the cells, they set electrons loose from their atoms allowing electrons flow through the cell produces electricity.

Solar thermal power plants utilize various techniques to gather the sun’s energy as a source of heat. Thus generated heat is used to boil water to drive a steam turbine that produces electricity. Solar energy is praised as an unlimited energy source that is noise and pollution free.

Solar energy is used directly for generating power or indirectly as stored thermal power with solar power network photovoltaic panels; stored thermal energy can in turn be used for supplying hot water for use. In U.S. 18% for water heating and 45% of residential energy usage was for space heating. The rest 47% was consumed for space lighting, cooling, electronics, computer, refrigeration, and others. The following is a list of advantages and disadvantages of solar energy.

Solar energy facts – Advantages

  • Solar energy is plentiful and freely supplied by nature,
  • Solar energy systems are eco-friendly,
  • Solar panels can be simply placed in residential
  • On grid solar panel installations supply generated electricity to the power network
  • Off-grid solar panels accumulate produced power for own use
  • Cost of solar panels has been falling and is expected to continue in the future, which as a result will slowly become reasonably more feasible without any need of subsidy incentives, and
  • The US offers Federal solar tax credit, utility incentives, rebates and subsidies to house owners interested in solar power.
  • Solar power is dependent on climate conditions; thus it is considered extremely unstable and undependable energy source.
  • The cost of solar panels is high and needs to be supported by financial incentives for solar energy initiatives to balance their initial investment, and
  • The system requires lot of land or surface area to collect suns energy.
