The disadvantages of solar cells and solar panels by starting with the disadvantages we can address them up front in the spirit of transparency.
Photovoltaic solar panels disadvantages.
Here s a list of the top 7 disadvantages of solar energy.
Not shining at night but also during daytime there may be cloudy or rainy weather.
Compared to other renewable energy sources such as solar thermal pv systems have a relatively low efficiency level ranging between 12 20.
Solar power depends on daylight shining on them in order to generate electricity a natural consequence of this is that solar cells and solar panels cannot generate electricity at night.

Another one of the disadvantages of solar energy is the huge upfront costs.
When you build your new solar power system you will have to pay for the panels batteries wiring the workers that installs them and so on.
Installing solar panels on your roof will save you money in the long run but it s not a cheap purchase upfront.
Consequently intermittency and unpredictability of solar energy makes solar energy panels less reliable a solution.
This will cost money and you will have to pay anything between 3000 30 000 depending on how large of a facility you are building.
Disadvantages of solar pv in a nutshell as in all renewable energy sources solar energy has intermittency issues.
Perhaps the biggest disadvantage of photovoltaic pv panels is their limited efficiency levels.
