Every trustworthy solar configuration stands on a load plan: a named, timed and totalled list of what the system must carry. This guide shows how to build one for a home or a building, without inventing precision you do not have.

A load plan has three columns that matter: what the load is, when it runs, and whether it can move. Loads that can move — water heating, pumping, laundry, charging — are planning gold, because moving them into sunshine hours shrinks both array and battery. Loads that cannot move define the system's obligations. Group the plan into essential, daily and deferrable, and total each group separately; a single grand total hides exactly the information sizing depends on.
Be honest about simultaneity. Not everything runs at once, and a plan that pretends otherwise oversizes the system; a plan that assumes perfect staggering undersizes it. Note the realistic worst hour — the evening cooking hour at home, the full-production hour at a factory — and make sure the configuration answers for that hour explicitly.
The home configuration on this site comes with its household load reference, totalled and checked. Ask for the same pairing for your system, and attach your load plan to your inquiry so the reply can be checked against it line by line. If a supplier quotes without asking about loads, the quotation is a guess with a price attached.
Before ordering, confirm the minimum order quantity and lead time for your configuration, and ask which documents apply to the exact system you are quoted.
