The Survey

In order to establish the suitability for an off-grid installation then a survey will need to be conducted by our engineers. It is important to realise that not all properties and locations are suitable but we will do our very best to find a solution that works for you. There are many factors that influence the suitability of a location for an off-grid system, mainly relating to the generation ability in particular the orientation of your roof or plot, its pitch (slope) and any objects that could cause shading (trees, chimney, other buildings typically). We will discuss and explain our findings with you.

System Design and Quotation

Based on our survey findings, we will design a system that optimises your off-grid opportunity and maximises the generation potential to meet your consumtoin requirements.  We will calculate, using the Government’s Standard Assessment Procedure (SAP) the estimated annual generation of your system and provide these along with your quotation.


On acceptance of the quotation, an installation date will be agreed with you. Prior to the installation Greenmaze will organise for the delivery of the system components to your installation address. Scaffolding may be required for a roof mounted solar installation and will be erected they day before installation. We factor in a maximum of 2 days for a normal installation.  Our roofing specialists will be responsible for the mounting of the solar panels, while our electricians will install the isolators, inverter, generation meter and wiring inside your building
