Solar panels have been used as an alternative source of energy for over 40 years, and solar cell technology has improved significantly over the years. With this, the cost of installing solar panels has plummeted, with some states in the United States even offering incentives to households that use them.
Globally, Germany leads in terms of solar energy utilization, having 17 times more solar panel installations than the United States. However, federal and state incentives have led to a 69 percent increase in solar panel installations in the United States since 2011.
