Solar Electric Systems are Modular!
When you purchase a system, you can oversize the inverter, meaning that if you want a 5kw system in the future, but can only afford 1kw worth of solar panels today, you can buy a grid tie inverter that has a maximum capacity of 5kw and purchase 1kw worth of solar panels, as your budget increases you can buy more solar panels until you max out your inverter. I call this a “staged investment in a solar electric system” the end investment goal is to eliminate your entire electric bill, but you chip away a little at a time. There is a common misconception out there that all your capacity has to be purchased upfront which is totally not true. Go ahead, get started with a small system today, but don’t worry you have the ability to expand it later!
