Good question. Most systems use 16 to 18 panels, depending on wattage.
Each panel produces roughly 370–420W.
So, 6.6kW = 6,600W ÷ 370W ≈ 18 panels.
You’ll need around 30–35 square meters of roof space.
Flat roof? Sloped? Doesn’t matter. Installers figure it out for you.
On average, you’re looking at 24 to 27 kWh per day.
That covers your daily life — lights, fridge, washing machine, even your A/C.
And on good sunny days, you’ll have extra power feeding back into the grid. Yep, the power company
pays you. That’s a role reversal worth bragging about.
Honestly? For most families, yes.

Well, it’s not an exact number — depends on your sunshine and habits.
