I have installed Enphase solar photovoltaic systems for 7 years. I have taken solar courses at SEI in Paonia, Colorado, and I have volunteered with GridAlternatives in Colorado installing Enphase solar systems on low-income family houses. I have a ~20,000-Watt solar system on my home and have no utility bill. I am a huge fan of solar PV, and believe free energy from the Sun is the only way to go to insure a bright future for the Earth. The fossil fuels should be left in the ground where they belong, and disasters like Fukushima and Chernobyl should be a wake-up call for the human race! We must embrace renewables for the human race's energy needs.
