There is one disadvantage to Solar Power systems regarding reliability and consistency. A regular supply of sunlight is essential to keep generating electricity. Although, once the sun goes down, the solar energy level drops very fast.
This makes it important to have a power storage device in the form of batteries so that you can have uninterrupted supply of electricity. If there are no batteries, there is going to be no electricity without sunlight.
The majority of disadvantages about Solar Power are more economical in nature. Even after lots of technological development, the solar panels used to produce electricity are quite expensive. A single solar panel can generate only a small amount of power.
This means a large number of solar panels are required to generate enough amount of electricity to power houses and industries.
It is also required that the panels are angled properly through the day in order to align with the direct sunlight. Hence, it is essential to implement a mechanical adjustment system so as to turn the panels according to the angle of sunlight.
