Most domestic solar panel installations take 1–2 days from scaffolding going up to system commissioning. A straightforward 4kW system on a standard pitched roof is usually completed in a single day.
Here is what happens during the installation:
Scaffolding goes up first thing in the morning. Our team fits the roof mounting rails, then the panels, then runs the DC cabling down to your inverter location (usually the garage, utility room, or loft space). We connect the inverter, wire it into your consumer unit, and commission the system. If you are having a battery installed at the same time, that adds a few hours but is usually completed on the same day.
After installation, we handle the DNO notification (G98 for systems under 3.68kW, G99 for larger systems) and register your MCS certificate. The DNO notification can take up to 45 days for G99 applications, but your system is generating from day one.
Larger systems (6kW+), commercial installations, or properties that need electrical upgrades take 2–3 days. We agree a schedule with you in advance and Tam Mackie manages every project personally.
