If you have started to research solar power systems, you may have come across expandable solar power systems. An expandable solar power system is designed to allow you to increase the number of solar panels at a later stage. You may have enough room on your roof to install a 5kW system (20 x 250 Watt solar panels or equivalent) however your budget may only allow you to purchase 3kW worth of solar panels.
