Yes but missing the angle that if you don't get it and wait for 5 years, then you've just paid for 5 years of higher costs and that's money that could have been going towards paying for the panels.
Solar is great if you can install it for a reasonable price and have the affordability to get it, and the main benefit is the piece of mind it brings with monthly electric costs being lower.
Full solar install though is best if you can make good use of most of the energy generated, they will work better for people who use a lot of electric. Light users won't see much of a benefit.
