You have likely already made the choice to remove your reliance on fossil fuels and start a new life using solar energy as your main source of power. The technology used today is less-harmful on the environment and more efficient than what was in use years ago. Breakthroughs occur every day and every day you could be saving even more.
Don't walk on solar panels unless you really need to. They cost a lot of money, and you don't want to inadvertently damage them. Do not walk on the ends, as they are the most unstable parts.
One of the major benefits of solar energy is that it is renewable. The sun (generally) shines each and every day, and there is no reason to worry that drawing power from the sun will somehow render it unusable in the future. Using solar energy, therefore, is a safe and reliable way to power the Earth.
