Lowe's has begun stocking solar panels at its California stores and plans to roll them out across the country next year. Solar power is now accessible to anyone with a ladder, a power drill, and the gumption to climb up on a roof and install the panels themselves. Buyer be warned, however. The DIY part of solar goes beyond installation. Professional installers typically handle all the necessary paperwork, like clearance from the local utility and applications for a bevy of government subsidies that can make the system a whole lot cheaper.
