SOLAR POWER Sizing Your Solar Power System A solar power system can reduce the amount of electricity you draw from the grid, thus saving you money. However, to get the best return on your investment, your new solar power system needs to be sized according to the amount of electricity that is being used in your home while the sun is shining. An over-sized system will export substantial amounts of electricity to the grid to the benefit of your electricity provider, unless that surplus power is being stored in batteries for overnight use.
