During the last 5-10 years we are listening that solar will become the cheapest source to produce power in many countries. Unfortunately this is not the reality yet here in the USA, despite many states are trying to push hard the system. California, for example, is thinking about a law that will put an obligation for every new home to have a solar panel system to generate energy. I can image how home builders there are afraid of this proposal – and probably the price for customers there to buy a house will jump more.
I am a big believer in solar energy, and in my opinion this has to be a matter of study. Nevertheless the panels are still very expensive, and even with some government incentives it takes a lot of time to have your money back. In Massachusetts, depending on your house will be built, you just will have your money back in no less than 7-10 years, depending on the amount of panels you installed.
Gas continues to be the cheapest way to move in terms of energy, even in the New England region (where the prices are among one of the highest in the US). But I think that if you can afford the price it is worthy. I have them here in my home (12 panels) and for a house of more than 3,000 sf I pay no more than 150 dollars per month during the summer time. Also, every quarter, I have a deposit of 250 dollars in my account, because of the energy that can be sold in the market. But when I remember that I’ve paid of it around 18,000 dollars I also remember that the investment will take some time to break-even (around 8 years in my case).
As I mentioned I am a strong believer of solar panel energy, but I think the companies and the government has to continue to put efforts to find the best way to provide customers a more affordable price.
