Going solar is an exciting journey, but the paperwork can be daunting. Here is exactly what happens when you sign up with Trexon.

Week 1: Consultation & Site Survey

Our engineers visit your home to inspect your roof structure and electrical distribution board (DB). We use drone technology to create a 3D model of your roof for accurate panel placement.

Week 2-3: SEDA Quota Application

We submit your technical drawings to SEDA for Solar ATAP quota approval. This usually takes 5-10 working days.

Week 4: Installation Day

The exciting part! Our team arrives at 9 AM. Complete installation for a standard terrace house takes 1 to 2 days.

  • Day 1: Mounting rails and panels.
  • Day 2: Inverter, AC/DC cabling, and Earthing.

Week 5-8: TNB Meter Swap

Once installed, we notify TNB. They will process the application and come to your home to swap your old meter for a bi-directional Solar ATAP meter. Once the meter is swapped, you can turn on the system!

Before you begin, use our solar calculator to find the right system size for your home. Then browse our packages to choose a bundle that fits your budget and energy goals.
