When using solar power, you do not have to worry about harming the environment in any way. Fossil fuels send harmful greenhouse gases off into the atmosphere, and they contribute to global warming and climate change. However, solar cells have no impact on the environment and are safe to use.
To realize even better savings, purchase grid tied panel systems. If your panels are connected, you might be able to sell extra power to the local utility. This should help you pay for your solar energy system and will also give you the option to draw power from the main grid in case your panels are not functioning.
