Preliminary system estimate

Size a home solar system from your appliance list

List what you run and for how long. This worksheet estimates your daily energy use, then the PV array, inverter and battery a system would need to cover it — the same way GoKoval scopes a job before a site visit.

These numbers are a planning estimate. GoKoval confirms final sizing with a site visit — roof space, shading, wiring and surge loads all affect the real design.

Figures are preliminary planning estimates generated from the inputs above and standard sizing assumptions. They are not a quotation and do not account for site-specific factors such as shading, roof orientation, wiring distance or appliance surge current. Contact GoKoval Solution Unip.
