Pros and Cons of Solar Energy

July 13, 2019

Solar energy is becoming a popular source of power in most parts of the world. It is a clean, eco-friendly and a renewable type of energy. It is ideal for remote areas and in industries to reduce the cost of production. Solar energy is energy captured through solar panels from the sun and converted into electricity. The energy is usually in form of solar radiation. The photovoltalic solar panel receive the solar radiation and produces direct current which cannot be used by most appliances. An inverter converts the direct current into alternating current. Large batteries store the electricity for future purposes. Wiring is then done to power various appliances.


Reduces carbon emissions

In comparison to electricity generated from fossil fuel solar energy produces no harmful emissions after installation that depletes the ozone layer. Hence, its more environmental-friendly.

Cuts on electricity bills

If you produce electricity from solar you don’t incur bills that are charged for using electricity from the grid hence it is a return on investment. Surplus energy can also act as source of income by supplying excess energy to the grid.  The use of solar energy in manufacturing reduces the cost of production incurred, increasing the profit margins.

Low maintenance costs

Solar system requires very little maintenance and repair work because there are no moving parts hence no wear and tear. Cleaning of the panels can be done twice in a year therefore maintenance is generally easy. Solar panels have a long life span of between 25 – 30 years.

Renewable resource

Sunlight is readily available in most parts of the world during the day. Therefore, it can be harnessed adequately as long as the sun is shining. This makes it a very reliable source of power.

Technology development

Innovation in quantum physics and nanotechnology will see effectiveness in solar panels increase hence more output in future.

Diverse application

Solar energy is not only used in generation of electricity but also in thermal dynamics. It is also used in most building for heating. Solar panels are also used in pumps and other appliances which are becoming rampant.

Better option in marginalized areas

Solar energy is an appropriate technology for marginalized and hotter part of a country which are not usually connected to the grid. This ensures continuity of business even at late hours, stirring economic growth. Students from such areas are able to use clean energy that will not harm their health.

Reducing fires and destruction

High voltage involved in the grid at times causes fire and destroys highly valued appliances especially when faulty. This incidences can be highly reduced while using solar energy thus saving properties and lives.



A solar system has a relatively high installation cost. This is due to its components which include the solar panels, inverter and batteries. Installation and wiring done to complete the system also increases the cost.

Weather dependent

Solar energy is highly dependent on the availability of sunlight. Although the energy can be can be captured during cloudy days the output is limited. If there is no storage mechanism e.g. large batteries an alternative source of power is necessary.

Storage is expensive   

Large batteries are used to store solar energy through charging them during the day and using them later but it is an expensive way of storage.

Space consuming

Space is required in order to install the solar panel. Most panels are usually placed on the roofs which are not always enough. If you require more power, more panels are needed hence need for space. The space available must be clear to ensure that the solar panels receive the maximum amount of radiation otherwise  the output will be compromised.

Associated with pollution

Emissions of greenhouse gases do occur during transportation and installation of solar system although not to greater extent as compared to other electricity generation method.

Prone to destruction

Solar panels can be a target of destruction during war or conflict which can lead to huge loses. Extremely harsh weather such as strong winds and hurricanes can also destroy solar panels.
