Solar panels are environmentally friendly and do not contribute to climate change like this is the case with fossil fuels because they do not emit harmful greenhouse gases such as carbon dioxide.

Solar panels harness Sun's energy and Sun is the most abundant form of energy available on our planet.

Solar panels are easy to maintain and have extremely low maintenance costs because there are no moving parts.

Solar panels do not contribute to noise pollution and operate extremely silently.

Solar panels are relatively easy to install.

Many countries across the globe offer favorable tax incentives and rebates to homeowners for using solar panels. The large number of U.S. states offer tax breaks for both residential as well as commercial solar panel applications.

You don't have to buy all required solar panels in the same time but can instead buy them gradually meaning you don't have to make an instant multi-thousand-dollar investment.

Solar panels do not lose much of their efficiency during their lifespan of 20+ years.

The typical warranty for solar panels lasts 25-30 years which is more than enough to make money savings on the long run.

Solar panel disadvantages:

Solar panels are still relatively expensive, even despite the recent decline in prices. The price of solar panel rooftop system in United States for average home is currently around $12,000-18,000.

If not installed properly solar panel can overheat itself.

Solar panels are made of several materials that are not environmentally friendly.

The recycling of old solar panels could cause some damage to environment if not done carefully because of silicon, cadmium, selenium and sulfur hexafluoride (a potent greenhouse gas), all of which can be found in solar panels and released during the recycling.
