More False PV Solar Myths 0

This is the third blog in a series on common myths about solar panels. To read the other two blog entries click here and here.

Myth 11: I will store the excess energy I generate in batteries.

Truth: Almost all of the systems installed today are tied into the electirictysolar panels linked to grid grid. This allows you to reap the benefit of net metering– excess energy you’re your roof produces during the day is sold to the electricity company and you electric meter spins backwards. If you use more than you are producing in the evening and at night, you use electricity from the power company.  This system is more efficient and less costly than bulky batteries that need replacing every five to ten years.

Myth 12: When the power goes out, my home is still powered.

Truth: This would be true if you choose to have solar batteries (see Myth 11 above). However, solar systems tied into the grid go out when the grid goes out. It isn’t safe to have these solar systems pushing energy back into the grid while electric crews might be out trying to fix a problem. Your solar inverter (that Boston Solar installs along with your panels as part of your solar system) recognizes that the grid is down and shuts down your solar system as well.

Myth 13: There are no jobs created by the solar industry.

solar installersTruth: The solar industry currently employs over 100,000 Americans. This number is constantly growing as neighborhoods, cities and states turn to solar energy. Our own local Massachussets solar teamuses crews based locally installing panels fabricated in the United States. The U.S. solar energy market grew 140 percent in the third quarter of 2011 over the same quarter in 2010 making it one of the fastest growing sectors in the economy!

Myth 14:  Solar Panels Have A High Carbon Footprint And Are Not Sustainable

Truth: Solar panels are most often made from silicon – one of the most common elements on earth (it comes from sand!). Of course this silicon needs to be refined. The refinement process takes place in huge ovens that do consume a lot of energy. However, it only takes 1 – 2 years for a solar panel to pay back the energy consumed in its construction. Any power generated after that is completely green, and solar panels can last 25 to 40 years! We consume silicone in many other forms every day – from cell phone covers to pottery glazes to implants. Solar panels are one of the few energy creating uses for refined silicone. Other forms of energy production have much longer pay back times.
