The Challenge
Nick bought a new build home but had missed out on spec-ing solar panels. He was conscious that this large house would be expensive to run so he wanted to reduce his electricity bills. He had also recently purchased an Electric Vehicle and wanted to ensure he could charge it for less.

"I regretted not adding solar when the house was built, but our installation partner made the retrofit process seamless. Having panels on both the house and garage roof maximises our generation, and the EV charger means I barely pay anything to charge my car."
