Use this guide to understand what should appear in a residential solar quotation. WattPK still reviews the complete combination because a strong brand alone does not make a complete system.
Panels determine how sunlight is converted into electricity and how much roof area the system needs.
The inverter controls how panel power is used by the property, battery, and electricity connection.
A battery is mainly about usable backup, not simply the largest number shown on the box.
A complete quotation should also explain the work that makes the main equipment safe and usable.
