What affects solar panel payback?
A useful payback estimate starts with the property, the system design, and how the household uses electricity.
Payback factors to compare
The same system can look different depending on energy use, roof fit, export assumptions, and financing.
Installed cost
Equipment, scaffolding, electrical work, battery choices, and installer scope all change the starting point.
Self-consumption
Solar is usually more valuable when the home can use more of the generated electricity directly.
Export route
Export tariffs can support the case, but they should be compared alongside household usage.
