This might be a good time to buy a solar energy system for your home. Consider leasing rather than buying equipment to reduce the initial investment needed. Companies such as Sunrun and SolarCity install solar energy systems for little or no payment, then charge for the power generated at lower cost than most utilities. Solar equipment prices are dropping fast – about half price from one year ago. At the same time, technological advancements are improving the performance. And since fossil fuel costs are expected to continue rising in the future, renewable energy alternatives such as solar become even more attractive.
