From cars to streetlights to irrigation pumps to remote communications towers, solar photovoltaics have many applications in our every day lives. Have you seen the inexpensive landscape lights you can buy at your favorite hardware store? They are actually quite an impressive combination of solar photovoltaics, LED light and reflector, rechargeable storage battery and control circuitry. Did you know that the typical rooftop photovoltaic panel can have a warranted life of 25 years and will likely produce 80% of its output up to 50 years or longer? With every day that we expand their use, envoronmentally clean and sustainable photovoltaics become more and more commercially viable.
