The initial cost of purchasing a solar system is quite high. Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system decreases. While solar panels produce clean, renewable energy, the process needed to manufacture them can damage the environment. The mass production of solar panels can cause the burning of fossil fuels and plastic waste.
I agree with your fifth point about the disadvantages of solar panels converting only 20 to 25% of the Sun's energy into energy. But before buying and installing a solar system in your home, there are some major drawbacks of solar energy to consider. Before exploring the advantages and disadvantages of solar energy, it's good to have an overview of solar energy. In general, the disadvantages of solar energy include the high cost, low efficiency, the space needed to install solar panels, the unreliability of exposure to the sun, and the high pollution caused by the manufacture of solar panels.
The main environmental disadvantages of solar energy are the fossil fuels needed for its manufacture and the wide range of toxic chemicals and rare earth metals needed for each panel. So let's go straight ahead and discover the pros and cons (pros and cons) of solar panels. This is a disadvantage of solar panels, but it may be something that will be overcome in the future with new technology. One area I didn't cover in terms of drawbacks is the cost and disposal of panels once worn out.
This means that residents of places such as the northern United States, Canada and Russia are at a disadvantage when it comes to solar energy because there isn't enough sunlight in a day for solar energy to be a complete solution. I've been following a post on Wiki Answers for a while about the pros and cons of solar energy and wanted to share the results. This becomes a disadvantage for solar panels, although they themselves produce green and renewable energy.
