Client & Location: Private Customer - Leicestershire
Project: 2.35 MWp Solar PV System with Module Optimisers
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.
System Modelling, Design & Export Constraint TA
Client & Location: Topbond Group plc / The Environment Agency
Project: 25 kWp Solar PV with 10 kVA Export Capacity
LHW Partnership LLP were engaged to provide detailed system design and grid connection services for the devlopment of a 25 kWp solar PV system within limited export capacity. LHW undertook export constraint modelling and a 10kVA export limited system with 90% non-constrained generation output was agreed upon and allowances were made for the future adoption of on-site energy storage.
Feasibility, Design & Project Management
Client & Location: Private & Northamptonshire
System: 250 kWp Tracked Solar PV System
LHW Partnership were employed as Project Managers and Technical Advisors to deliver a 250kWp solar PV system with single axis tracked framing system and module optimiser inverter based strategy.
The role included modelling, options appraisal, mechanical and electrical design, vendor selection, procurement and installer selection and management, system commissioning, site acceptance testing and O&M strategy.
Due Diligence Review & Inspection
Client & Location: British Gas Solar – Wrexham, North Wales
Project: 2.6MWp Solar PV
Year: 2014 & 2016
LHW Partnership were engaged to act as the client’s independent Technical Advisor and to undertake due diligence review of the proposed 2.6MWp ground mounted solar PV project for a Local Authority.
The DD review included a main and balance of system equipment verification, design review, PR verification, shading analysis, yield analysis, system modelling, design review, cable losses verification, HV system review, P50-P90 appraisal, grid connection offer review and a post-installation inspection.
ESOS Energy Audit and Appraisal
Client & Location: The Landmark Trust
Project: ESOS Energy Assessment - Building and Fleet Assessment
LHW Partnership, working in partnership with CLS Energy, were engaged by the Landmark Trust to undertake an ESOS audit and appraisal report for a number of the Trust's properties. The portfolio of 195 buildings and associated transport infrastructure are some of the most unusual in the UK encompassing accommodation in Castles, Chapels, Light Houses, Gothic Temples, Railway Stations, Historic Towers and a wealth of interesting historic buildings.
Client & Location: Private Customer - Henley on thames
Project: Ground Source Heat Pump
LHW Partnership LLP was instructed by a private customer to act as Technical Advisors for the installation of a GSHP system to deliver the property’s heating and hot water demands. As TA, we undertook an independent heat loss survey, assessed collector options, developed a technical specification and ITT, assisting the customer throughout the installation period.
The system was commissioned in December 2015 and will generate a total of 77,500kWh of renewable heat energy per year.
PV System Inspection and Acceptance
Client & Location: Various
Project: Rooftoop & Groundmount PV Systems
LHW Partnership LLP have undertaken on behalf of Asset managers, Local Authorities, Businesses and end user clients, over 75 site accetpance inspections of PV System instalatons from 10kWp to multi MW comprising over 200MW in total in line with MCS and IET PV Code of practice standards.
The work undertakn included design, documentation and site installation review and reporting.
Client & Location: Prater / BSkyB - London
Project: Commercial Rooftop Solar PV System
Year: 2014 – 2016
LHW Partnership was employed by Prater as specialist engineers to undertake all preparation and design works for the solar PV system at the BSkyB HQ. Services provided by LHW included applying for grid approval, full mechanical, electrical and plant room designs and a technical submittal. The role required integration with the project design team and post-installation inspection.
London Southend Airport – Stobart Group
Client & Location: Stobart Group / Syzygy Renewables Ltd
Project: Yieldworks - Export Constraint Modelling
LHW Partnership was instructed by Syzygy Renewables Ltd. on behalf of the Stobart Group to undertake export constraint modelling for a solar PV development at London Southend Airport.
The project had secured grid connection with the DNO however the connection agreement was subject to a limited export of 200 kVA. LHW undertook a Yieldworks analysis that assessed the site's half-hourly demand profile, generation profile, export constraint and load variance, determining the optimal system size to be 2500 kWp.
Unmanned Aerial Vehicle Infrared Aerial Inspection
Client & Location: Multinational Consultancy
Project: 8 MWp UAV Infrared Solar PV Farm Inspection
LHW Partnership LLP was instructed by a multinational consultancy to conduct an infrared inspection of an 8MWp solar PV farm located in Bedfordshire using UAV technology. IR UAV surveys combine aerial photography and infrared thermal imaging to quickly and safely assess the health of solar PV systems. The survey was quick and non-intrusive and the technology was able to identify underperforming or faulty modules invisible to the human eye.
LHW Partnership is certified by the Civil Aviation Authority and BNUC-S to pilot UAV for commercial purposes and staff members are Level 2 certified Thermographers.
Client & Location: International Developer – Democratic Republic of Congo
Project: Solar PV & Diesel Hybrid System
LHW Partnership were engaged to produce a feasibility report for the development of three 30MW solar PV parks in the Democratic Republic of Congo. The proposed solar farms were part of a large new town development and supplying three local mines. The objective was to review the project feasibility of the large scale PV parks in order to provide cost effective electrical energy to offset the expensive diesel based generation in an area where there are both intermittent grid supply and capacity restrictions from the local grid operator.
