You can get started with solar power by installing a small system to light your exterior lights or get a solar powered hot water heater. These little lights soak up the sun's rays during the day and shine a path through the darkness at night. These are very simple to put in, and they light up your outdoor space in a charming way.
This is a brilliant DIY hack for creating an off-grid water heater with just a simple handmade rocket stove, water barrel, and copper pipes! No pump! No propane!
