As research continues to find more reliable forms of alternative energy which are scalable and renewable, some researchers are focusing on concentrating sunlight to boost the energy collected by photovoltaic panels.
It may sound like a simple idea, but using reflective surfaces like mirrors to focus sunlight onto small areas of photovoltaic solar collectors, which minimizes the amount of silicon needed, greatly reduces the production costs per kilowatt.
