If I get solar is it recommended that I stay connected to the electricity grid?
Solar systems can be operated with batteries and it is conceivable that you disconnect from the grid. These systems are called off grid solar systems. Nevertheless such systems require a substantial battery bank which adds significantly to the cost of the solar power system. In most cases an off grid system only makes sense in remote areas. It is anticipated that in the future small storage system for homes will come to the market at more reasonable prices and this will allow you to use your stored solar power during sunless periods during the day and at night.
