Before we discuss about the Solar Energy Advantages and Disadvantages let’s have a quick talk about What is solar energy?
Solar energy is radiant light and heat which directly comes from the Sun. This energy is the form of solar radiation, which makes the production of solar electricity possible.
Electricity can be produced directly from photovoltaic, PV, cells. (Photovoltaic literally means “light” and “electric.”) These cells are made from materials which exhibit the “photovoltaic effect” i.e. when sunshine hits the PV cell, the photons of light excite the electrons in the cell and cause them to flow, generating electricity. [1 Noted]
For the kind information, the earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere. And approx 30% of the energy s reflected back to space while the rest is absorbed by clouds, oceans and land masses.

Advantages of Solar Energy
- One of the most considerable advantages of Solar energy is it’s most promising energy forms and also renewable, non-polluting and it also contributes to sustainable development and job creation.
- Solar power or developing a solar energy plan which helps in creating a pollution free place causes no greenhouse gases to be emitted after installation.
- Termination of foreign dependencies like oil and fossil fuels. Solar energy can be used as a fuel.
- The renewable clean power that is available every day of the year, even cloudy days produce some power.
- Return on investment unlike paying for utility bills.
- Virtually no maintenance as solar panels last over 30 years.
- Creates jobs by employing solar panel manufacturers, solar installers, etc. and in turn, helps the economy.
- Ability to live grid free if all power generated provides enough for the home/building.
- Can be installed virtually anywhere; in a field to on a building.
- You can use batteries to store extra power for use at night and other works as well.
- Solar can be used to heat water, power homes and building, even power cars.
- It will be much safer than the traditional electric current.
Disadvantages of Solar Energy
- High initial costs for material and installation and long ROI.
- Needs lots of space as efficiency is not 100% yet.
- No solar power at night so there is a need for a large battery bank.
- Sometimes if something goes wrong with the connection maintenance will be a burden for the solar panels.
- Depending on geographical location the size of the solar panels vary for the same power generation.
- As it depends on the solar energy if whether changes to cloudy and rainy day then there may be lower production in power.
- Solar panels are not being massed produced due to lack of material and technology to lower the cost enough to be more affordable
- Solar powered cars do not have the same speeds and power as typical gas-powered cars
- Lower production in the winter months.
That’s all for Solar Energy Advantages and Disadvantages, Solar energy will be very useful to people where they can’t produce electricity by building hydro powers. Solar energy is one of the easiest sources to utilize for the electricity.
