quotes in three days
I put it off for a year because I had no idea even roughly what it would cost. The calculator gave me the ballpark in two minutes and the quotes arrived within three days. The gap between the most and least expensive quote was almost 2,000 KM for practically identical equipment — I only found that out because I had them side by side.

years to payback
We rent out two apartments in summer and the air conditioning runs all day — exactly when the panels do best. That made it pay off faster than the calculator shows, because we consume nearly everything we produce on site.

contracts per lead
We used to get calls along the lines of “how much does solar cost” and spend half an hour on basic education. Now people arrive with an estimate, they know the ballpark, and the conversation starts at the roof and the grid connection. We closed four contracts out of eleven leads in the first three months.
