Solar Energy Advantages Disadvantages

The solar energy advantages disadvantages in view of the technological and economical aspects.

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. It is expected that utility electricity will be more and more expensive in the future; therefore securing a free of charge electricity during the expected future escalation of energy prices is really a benefit
• UP to 50% more solar power. Request a free residential solar evaluation.Eliminate high electric bills

Disadvantages and Limitations

The disadvantages, or better call them limitations are:

• Present time price of solar generation equipment and especially of solar electric panels is still high. There is a clear trend of price reduction though and the available tax credits and grants can mitigate the high cost impact
• It is a prerequisite that solar panels are installed on a south facing unshaded roof (or an unshaded area of the backyard)
• Solar panels produce electricity only during daylight. A grid connected system doesn’t need batteries back up because the utility can supply the night time needs. Off grid solar systems (for homes not connected to the grid) however do need to have storage batteries backup. Batteries need more care and they present shorter life span between 5 to 10 years
