Solar energy is renewable, efficient, and cost effective. How could you not convert to solar energy? Sunlight is a free and infinite source of power, so running out of it is not an issue. Once solar panels are installed, they require a small amount of maintenance a year to keep them in order and are very easy to operate. Finally, solar power can severely reduce one’s monthly utility bill. Solar power is a technology, not a fuel. That stated, prices fall as time goes down.
