Forensic PV Testing.           PV Farms

In 2020 and 2021 LHW have been investigating a number of PV farms at Southwick in Wiltshire, and Ardleigh in Essex, Falmouth in Cornwall, and a number of other locations, to determine reasons for possible performance anomalies. Conclusive evidence was found by field testing avoiding need for expensive mobile laboratory or Test Lab review.

1.3MWp PV Project Peterborough

A 1.3 MWp PV project was successfully commissioned in Peterborough for one of world’s largest industrial diesel engine manufacturers. LHW provided design, vendor selection Technical advisory, grid connection/constraint, and site review and acceptance services. Other similar projects in progress included 2.8MWp PV/Battery system for a large Pension fund, and PV farm projects for a local authority.

PV - Wind Battery Hybrids Major Utility

Since February 2021 LHW has undertaken engineering grade energy reviews on over 60 utility sites in South of England for adoption of PV / Wind & Battery to lower energy import ranging from 100kW to 8 MW per site with varying hourly energy tariff scenarios. The ability to create good quality Half Hour data for both PV & Wind has provided conclusive evidence of the benefits of E-W facing PV Systems, and the massive importance of copowering sites with wind turbines that generate more energy in the winter periods.

Solar PV - Root Cause Performance investigation

In a UK (and very likely geographically wider) first, LHW undertook a full toolbox of field testing to successfully get to the root cause of an underperforming PV system. The testing included Electrcroluminescence, Photoluminescence, UV Fluorescence, IV Curve, IR Thermography, Module Shunt resistance and  Module string series resistance testing.   This full service approach requires a suite of good test equipment and associated operational and analytical competence, but is the only approach to provide the appropriate technical service level to provide the confidence to identify the issue.

Expert Witness - PV- Battery Storage Dispute

LHW are providing technical Expert Witness services in line with the requirements of Part 35 and Practice Direction 35 for a solar PV and battery project dispute.

PV Farms Technical Advisor

LHW have been appointed as Clients TA on 2 new PV farms 20MWp & 3MWp for Kent County Council being installed in 2021.

Recommendations for fire safety with photovoltaic panel installations

LHW has been appointed to update and harmonise the document published by the Fire Protection Association and RISC Authority - "RC62 Recommendations for fire safety with photovoltaic panel installations" 

Transactional Due Diligence

LHW has been engaged as technical advisor on a number of roof mount  , and ground mount  PV farms in USA to provide transactional due dilgence expertise. The projects incude fixed, tracked, and rooftop systems and comprise over 200MWp of capacity.

Fuel Cell Storage System

LHW have preordered a LAVO 40kWh Hydrogen Fuel Cell system to gain familiarity with hydrogen technology as an energy storage medium and will be installed in Bedfordshire. The system developed in Australia will ship in 2022.

Engineer grade inspections

As probably one of the more focused field specialist engineering organisation in UK with focus on engineerng grade forensic review of asset, LHW have been busy again undertaking inspection and testng on PV farms  and roof top sytems. The image aboe is a 15MWp installation near Reading. 

Detailed PV modelling

LHW have undertaken a number of highly detailed PV models for large rooftop systems, modelled to a level not normally undertaken for such projects.

Engineering Surveys

With lockdown restrictions easing, in May LHW will be undertaking a significant number of engineering site surveys having already pre-determined the optimal PV/Battery mix for a range of Waste water, Potable water, Reservoirs and Pumping Station locations for a client in UK.

PV - Demand Modelling

LHW has undertaken multiple models of 18 sites for a large energy user both  South & East West facing at various pitched both including  and without battery storage to maximise on site consumption of generated electricity to determine optimal PV system sizing.

Technical Advisory Role

LHW is acting as Technical Advisor for a 2.8MWp “Behind the meter” PV , Battery & EV charging station addition to a business park in East Anglia.

PV System performance investigation

LHW undertook testing on a number of installations that were suspected of underperfoming. The tests involved both string and module level testing, and provided very conclusive trends and results to affirm the issues. 

 

A number of tests were undertaken, and Electroluminescent testing will be undertaken at a later date.

Salix GSHP Funding

Working with a local authority and CLS Energy. LHW successfully undertook the modelling to successfully secure £2m grant funding for a 200 kWe GSHP, 400 kWh battery & 500kWp PV array to provide renewable energy to a sports and leisure centre eliminating nearly all the gas demand. 

Wind Turbine Modelling

To supplement a global leading position in PV, and energy simulation modelling, LHW has invested in Windpro wind simulation software. This will enable more accurate half hour energy appraisals combining PV, wind, batteries and demand side management. LHW has experience in onshore wind going back to Delabole and Carland Cross wind projects in 1990. 

UAV/Drone inspections

Holding the latest CAA approval and regulation changes on 31/12/20, LHW can legitimately undertake drone rooftop PV inspections in nearly all urban and rural areas. This makes the use of drones almost obligatory if correct feasibility, design and operational issues are considered.
