If you cannot afford a full-scale solar energy system, consider investing in a smaller one. Some vendors offer small systems designed to power a water heater or a generator. This small investment should help you save money within the next few years and you can easily expand your solar energy system by powering more appliances with solar panels.
Panels have to face the sun to draw power. You get the energy from the sun, so it's important for the panels to be located in an area where they can get all the solar energy possible.
For families with four people, a solar energy system should produce approximately 5,000 kilowatts. This allows you to wash and dry five loads of laundry a week, run the dishwasher five times a day and power multiple televisions and lights. When deciding on the system, choose one larger than what you think you need. You can always sell the extra power produced to the electric company.
