When the space and resources are available, your best bet for maximum solar energy gathering is a panel system with sun tracking. This type of system tracks the sun's movement across the entire day, and even the entire year. This may cost you a little more at first, but the results in the end are worth it.
If you decide to put solar energy panels on your home, remember to keep them clean. Your solar panels must reflect the sun's rays in order to store the sun's energy for use in your home or business. If they are dirty, they can not effectively do this. By keeping them clean, you will get the most bang for your buck!

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.
