How Solar Sizing Works In GridGap

The Solar tab brings together day loads, battery recharge demand, solar production assumptions, panel count, and advisory string-related outputs.

Energy requirement

Solar energy for day loads, battery recharge Wh, solar energy for battery recharge, and total solar energy required show how the app builds the solar burden. Required solar W converts that burden into a practical array-size target under the chosen assumptions.

Panel count outputs

Raw minimum panel count is the energy-based minimum before practical string cleanup. Installed panel count is the final clean installed count the app suggests. Day-only panel count and battery-recharge panel count help split the burden conceptually.

Panel Size, Panel Voc, and Panel Vmp remind you which panel assumptions the output used.

Cloud and surplus interpretation

Cloud factor and the cloud sensitivity section show how changing conditions can affect the required panel count. Solar surplus / shortfall is a planning interpretation, not a guarantee of performance under every real-world condition.
