If you've already made your home as energy efficient as possible, and you still have high electricity bills and have access to a good solar resource, you might want to consider generating your own electricity with a solar power system. Solar panels can be easily installed onto ground- or roof-mounted racks, and new products are available that integrate solar cells with the roof, making them much less visible than older systems.

You should consider several factors if you want to install a solar power system, such as your solar resources, siting and sizing the system, the type of system (grid-connected or stand-alone), and electrical safety. Because of the complexity and need for proper installation, it's best to have a professional solar contractor install your system.
