Best answer

Intermittency. One of the biggest problems that solar energy technology poses is that energy is only generated while the sun is shining.Land Use. Another concern is that solar energy may take up a significant amount of land and cause land degradation or habitat loss for wildlife.Scarcity of Materials. Certain solar technologies require rare materials in their production. This,however,is primarily a problem for PV technology rather than CSP technology.An Environmental Downside. The one environmental downside to solar technology is that it contains many of the same hazardous materials as electronics.

But before you go and install a solar system on your house, some major disadvantages need to be weighed in. With solar power having the highest initial costs of any other renewable energy source, you would think it would be pretty good. But in reality, solar panels have low efficiency.

The environmental impacts associated with solar power are land and water use and pollution, habitat loss, and use of highly hazardous materials in the manufacturing process. Thinking back to the installation area, land use by solar fields can be massive, and unlike with wind power, sharing the land for agriculture uses is not an option.

Although solar energy has some flaws like inconsistency, inefficiency and high initial capital outlay, the upsides pretty much dwarf the downsides. The upsides to solar energy include low greenhouse emissions, beneficial to remote locations that are not connected to the main power grid, and the provision of green jobs.

Another method used by some solar panel systems is to use a backup from other non-renewable energy sources. These types of systems, however, cannot be considered as purely environment-friendly.
