The cost of photovoltaic solar panels is expected to drop another 36 cents per watt by 2017, according to new research by cleantech market research firm GTM Research.
While this drop in solar panel prices will help to make solar affordable to more people, which will increase the size of the solar market, this ongoing cost reduction means much more than that.
Currently, solar panels are backed up by natural gas and various other types of power plants on the electricity grid. However, solar panel costs of $0.36 per watt make it more feasible to install additional solar panels to back each other up instead of using any other type of power plant (for off-grid setups), reducing the need for batteries.
