4. When bigger can be smarter
Why some people choose a larger system
Increasing the size of the system is sometimes not as expensive an upgrade as you might think so it is a common practice among savvy homeowners to choose a bigger system.
The larger system gives more breathing room in poor weather, more headroom for future usage, and stronger self-consumption when paired with battery.
The right answer still depends on the house
Roof space, shading, budget, and electrical scope all matter, so bigger is not automatically better for everyone.
The practical answer is to balance ambition with what the home can support well.
