Building a calculator

I have enjoyed building a “solar panel calculator” this week. The client wanted a tool that allows visitors to their website to enter their postcode, be presented with a map of their house, click the four corners of the roof and be given back an estimate of how much money they could make from solar panels.

Phew, quite a challenge, but by breaking it up into steps I have now got the prototype working well. Now just need to make it look pretty before handing it over to the client.

Do you need a tool for your website or a smartphone app?  Why not challenge me to make something cool for you.
