Solar Energy Cons:
• The major con of solar energy is the initial cost of solar cells. Currently, prices of highly efficient solar cells can be above $1000, and some households may need more than one. This makes the initial installation of solar panels very costly.
• Solar energy is only able to generate electricity during daylight hours. This means for around half of each day, solar panels are not producing energy for your home.
• The weather can affect the efficiency of solar cells.
• Pollution can be a con of solar energy, as pollution levels can affect a solar cells efficiency, this would be a major con for businesses or industry wishing to install solar panels in heavily polluted areas, such as cities.
Overview
Above is a list of many solar energy pros and cons, and although not definitive, you can see how the number of pros relating to solar energy, greatly outweighs the cons of solar energy.
The main reason we are not seeing a large amount of solar energy technology installations is due to cost, and unfortunately, as the price of fossil fuels remains lower than the initial investment towards the currently available solar panels, we will not see a mass shift towards solar electricity production.
