Why worked examples help
Calculators give you a number, but a full worked example shows you the whole picture: which panels and inverter go together, how much energy the system makes across the year, what it costs to install, and how quickly it pays for itself. Each example links to the exact calculators used, so you can plug in your own numbers and adapt it to your home.
Start by finding your system size with the panel calculator, then design the whole thing in the system report builder. For local tariffs and payback, see Solar by Country.
