Technical Advisors


Client & Location: Private Customer - Leicestershire

Project: 2.35 MWp Solar PV System with Module Optimisers

Year: 2016


As Technical Advisors, LHW Partnership assisted with the Ofgem pre-accreditation process, developed high level designs for the preparation of a technical specification for securing project funding. LHW Partnership undertook system modelling, procurement analysis, prepared construction drawings, liaised with the local DNO and upon commissioning, conducted a site acceptance inspection.


The design of the system overcame a number of on-site obstacles, including a National Grid gas main which crossed the site. The system design incorporates JA Solar modules with on-board SolarEdge optimisers and due to the use of some of the most innovative technical solutions currently available, the solar PV system is considered to be one of “the most efficient solar farms in Europe”. Working in close collaboration with Solar Advanced Systems Ltd. and Hopley Electrical Services Ltd. the development transformed from a green field site to a fully commissioned solar PV system in just three weeks.
