With rising interest in alternative green forms of energy, more and more people are taking a closer look at solar energy advantages, disadvantages and both sides of the argument. On the whole, the advantages far outweigh the disadvantages, but the differences are important for discussion.

Probably the largest advantage of using solar power is that the sun is available as an abundant renewable energy source. As our most powerful star in the solar system, the sun is estimated to have enough energy to power the entire needs of the globe for over 40 million years. When compared to traditional energy sources powered by fossil fuels, the power of the sun is an unending readily available power source.

Another advantage of solar energy is that it is being recognized as a legitimate option for providing an abundant and unending source of energy for homes and businesses. As a result, governments are offering financial incentives to homeowners and businesses willing to invest in a solar power system and install one in their home or business. Today, major companies like Frito Lay, Johnson and Johnson and others are proving that solar power can be a sustainable source of energy as part of an ecologically friendly approach to business.

While the initial outlay of money for a solar power system can be substantial for the average homeowner, government incentives help offset the cost and most homeowners quickly realize a return on their investment within a short period of time. In fact, they may discover that they are easily able to sell power to their local utility company, resulting in a profit for themselves.

One of the best advantages of solar energy is that not only is it a green sustainable energy source, but it also reduces dependency on foreign sources for energy. This means that countries willing to invest in solar energy and other green renewable energy do not need to be at the mercy of geopolitical events or agreements. Instead, they can focus their attention on being energy independent.


The primary disadvantage of solar power is the needed initial outlay of money to install a solar power system. However, offsetting this is the availability of governmental tax incentives to help with the cost of installation.

Another disadvantage can be the need to install numerous large solar panels for solar energy collection. Many homeowners choose to have solar panels installed conveniently on their roofs and this is also one of the preferred locations for solar panels for many businesses.

Also, solar panels have the distinct disadvantage over other green power sources like wind in that they do not collect energy when the sun is not shining, whether it is during evening hours or when clouds or pollution are present to block the sunlight.


With increasing interest in the availability of green alternative energy sources, interest in solar energy has increased in recent years. While there are distinct solar energy advantages, disadvantages have merit too and bear discussion. Overall, however, the advantages of solar power outweigh the disadvantages.
