System size should follow how a property actually uses electricity through the day, not just its annual total. Here is how that sizing actually works.
In short: this article is general information for the fictional Solara Energy portfolio demo. A specific property always needs assessment against its own roof, wiring and usage.
An annual total hides the one number that matters
Two properties with identical annual consumption can need very different systems if one uses most of its electricity at midday and the other in the evening. Sizing against the annual figure alone tends to produce a system that is either oversized for self-consumption or undersized for the load.
Daily and seasonal shape drives the array size
Usage data broken down by time of day, and ideally by season, shows how much of a property's consumption solar generation can realistically cover, and where a battery or shifted usage would close the remaining gap.
Usable roof area is the ceiling, not the target
The maximum array a roof can physically hold is rarely the right size to install. A system sized to the load, within the roof's limits, generally makes better economic sense than one sized purely to the available surface.
Size against the load, confirm against the roof
A well-sized system starts with how a property actually uses electricity, checked against what the roof and the electrical installation can support. Either factor considered alone tends to produce the wrong answer.

Property-specific next step
Turn the article into a useful question about your own property.
Send the roof, electricity context and the decision you are trying to make. The next step should be an assessment, not another generic article.
