Solar Planning App

A planning tool that does the math for solar installers.

A web app for a solar company, built for the people who install the panels. It calculates system size, costs, and savings, measures roofs on a map, and generates client-ready reports.

Context

Confidential client, built by David before Redtekk.

Role

Lead engineer in a team of 6 to 8 developers

Stack

Angular · Laravel · Azure · Scrum

Installers did energy and cost calculations by hand. It was slow, easy to get wrong, and every client report had to be put together manually.

The team built a calculation engine behind a simple interface. Installers measure roofs by drawing on a map, see cost and savings projections instantly, and send out branded reports the app builds for them.

Inside the build
01

Calculation engine

Energy output, costs, and savings computed from location, energy needs, and panel specs.

04

Automatic reports

Client reports generate themselves with the company branding and layout.
