Where do the default numbers come from?

The 1,600 kWh/kWp specific yield and €0.13/kWh are typical Maltese values used as a starting point. Both are editable on the page, and both are listed in the assumptions under every result.

Why does payback need my quoted cost?

Because we will not invent a system price. Payback is only honest when it is divided by a real quote, so the customer supplies that number.

Does it account for feed-in tariffs?

Not separately. The current model values generated energy at the electricity price entered, and says so in the assumptions. Tariff-specific logic can be built in per market.

Is the estimate binding?

No. It is a planning figure. Real output depends on pitch, orientation, shading, weather and equipment — which is exactly why the shading factor is a visible input.

Industry · Solar

Show the payback before the sales visit.

Consumption, system size, generation, annual saving and simple payback — computed from the customer’s own bill, with every assumption on screen and editable.

Why this exists

Solar is sold on one number the customer cannot work out themselves: how long until it pays for itself. Most sites answer it with a brochure figure that assumes a roof nobody has.

This estimator starts from the customer’s actual bill, sizes a system, and shows generation, offset and payback — with the electricity price, specific yield and shading all visible and editable. Payback uses the cost the customer types in, so it reflects a real quote rather than an invented one.
