How Reliable Is Solar Power?

Improvements in solar panel technology have increased the reliability of solar power.

Solar power does not require the burning of fuels, massive factories or heavy industry to facilitate power production. It is viewed as a more environmentally friendly power source compared with coal or natural gas, but some question its reliability.

The Source

The fossil fuel supply is finite, but as long as the sun exists, it will generate solar power. Solar power is not burdened by cumbersome logistical obstacles, such as human transport and storage. Solar power is absorbed, not harvested, which eliminates intermediaries. The source of solar power is reliable.

Technology

New solar concentrators use lenses and mirrors to focus solar energy, and new solar batteries are using lightweight lithium air technology, according to the Massachusetts Institute of Technology. A solar-powered home can be free of the power grid. Properly placed windows can also passively absorb solar power to heat the interior.

Reliability Speed Bumps

Location, weather and maintenance impact solar power reliability.

Weather and geographic location can affect the reliability of solar power. Clouds, rain and snow can obstruct the collection of solar power. Solar panels must be cleaned and cleared of dirt, snow and other debris to operate at top efficiency, and solar batteries require ongoing maintenance.
