More and more homes are switching to solar energy as their main back up energy source. This can be attributed to recent advances in solar energy components manufacturing that have resulted in cheaper and more efficient solar systems.

1. Solar panel prices have fallen more than 50% in the last 10 years
2. The efficiency of the panels has as well improved massively.
3. The cost advantage of installing a solar system has fast outstripped that of running generators
4. Solar energy is clean and noiseless
5. Solar energy units are low-maintenance units
