Solar system sizer

Get a feel for the right system for your home — panel count, inverter size and whether a battery makes sense.

As a rule of thumb, every solar panel is about 0.475kW, so 10–12 panels make a ~5–6kW system (6kW inverter) and 13+ panels need an 8kW inverter. The inverter brand depends on how you use power: grid-tie now (Deye), battery-ready hybrid (Deye or Sigenergy), or all-in-one battery system (Pylontech Force H3X). Systems of 21 panels or more may trigger DGA compliance — we handle that for you.

Daytime-heavy users get more from solar without a battery; evening-heavy users benefit most from storage.
