Solar planning for Waimea homes
A production estimate should reflect the actual property rather than assuming the same conditions as the Kona coast.
What we review first
- Recent electric-bill history and major household loads.
- Roof or site orientation, shading, available area and equipment location.
- Grid-tied solar versus solar + battery backup versus off-grid goals.
- Future loads such as EV charging, additional air conditioning or home improvements.
- Backup priorities: essential loads, larger load groups or broader whole-home goals.
Why battery sizing is separate from solar sizing
Solar array size is primarily about energy production. Battery design is about stored energy, discharge power, backup duration and which loads must remain available. Treating them as separate but coordinated design decisions produces a clearer plan.
