Self-building or extending? Solar decisions shift
If your roof doesn't exist yet you have options that retrofit homeowners don't: in-roof mounting (panels flush with the tile line), integrated solar tiles (Tesla, GB-Sol, Solecco), and bundling the install into the main contractor's quote so the VAT works out differently.
The big tradeoff: integrated tiles look better and add property value but cost 2-3x more per kWp than panel-on-roof. In-roof mounting is the middle ground and is what we recommend for most self-builds — it's flush, weather-tight and uses standard panels.
We're building a self-build hub with: in-roof vs on-roof cost comparisons, integrated tile reviews, timing (when in the build to bring solar in), and how to brief your main contractor so you don't end up with an awkward retrofit.
