The average cost of an IGS Photovoltaic (PV) Solar System is between 20 and 25K. As seen in the graph below, this customer paid approximately 200 dollars per month for their non-renewable energy supply. With their new PV Solar System, their energy bill dropped from 200 dollars per month to 15 dollars per month. Let’s assume your system costs 25K. In the 25-year lifetime of your PV Solar System, you will save 36K. Solar energy is a long-term, low-risk investment for you, the purchaser, and the planet.
