Purchase batteries to store excess solar energy. These batteries are similar to rechargeable batteries; however, they use the sun's energy to power up the batteries. This energy can be used in the evenings and at night to help power your appliances, televisions and lighting requirements. These batteries are relatively inexpensive making them a great choice for the beginner.
A charge controller is a great addition to any solar array, specifically those that are working above 10 watts on a regular basis. These small devices act as "ON" and "OFF" switches to protect your batteries. They prevent overcharging from damaging your batteries and can provide more advanced charging options depending on the make and model.
If you are thinking about having a solar system installed, make sure that your home or business is suited for it. Sometimes the layout of the roof will not accommodate the proper angle for maximum energy production. Talk to more than one company to ensure the contractor is being honest about your solar situation.
