Technical Training - PV analysis

LHW have been engaged by a forward thinking Asset owner & their O&M provider to provide technical training on PV testing methodologies used to help root cause analysis of PV system underperformance.

PV System modelling

In a month when travel was challenging, LHW were engaged and completed over 30 PV simulation models for clients ranging from 30kWp to over 300MWp, including roof top, and ground mount in locations from Columbia, Ireland, Lake District and a pan national warehouse portfolio. In all over 400 MWp of projects were modelled.

Building Heat Loss Surveys

In March, LHW undertook a number of building heat loss surveys in the City of London, and elsewhere. The work resulted in a development of a system modelling tool for pragmatic determination of building "U" values of ageing building stock, fundamentally important for heating system improvement.

PV Installation Site Acceptance services

LHW is providing Technical Advisory services and Siite Acceptance inspection and reporting for a London Community Energy organisation and one of the UK's largest County Councils for nine PV rooftop and ground mount installations comprising over 500kWp of installed capacity

NHS Trust PV Feasibility

LHW have completed a detailed feasibility assignment for two NHS Trust Hospitals in England reviewing a range of options including rooft top and retrofit of car ports. As a large energy user the NHS is loooking at ways to energy reduce costs and CO2 emmisions in a cost effective manner.

PV System performance investigation

In the first PV farm investogation of 2020, LHW undertook a range of daylight testing on a system, identifying low shunt resistance (PID) as the probable reason for system under performance. The testing , a scientifically correct and yet not a recognised mainstream IEC testing methodology helps provide a large amount of additional information on PV system performance issues.

Technical Advisory Role Wimpole Hall - National Trust

Since 2016 LHW have been providing Technical Advisory services to The National Trust for a large 30 borehole Ground Source Heat Pump and 400kWp PV array. In February the PV was connected to the grid concluding a very successful technical assignment

PV Feasibility

LHW have completed a detailed feasibility study with granular PV modelling of a large retirement home in London. The feasibility demonstrated that if careful Half Hour demand modelling is undertaken, the viability of solar is now in context undisputable even without subsidy.

PV Car Port, EV & Energy Storage strategy.

LHW have undertaken a detailed energy study, technical and commercial feasibility and strategy for the adoption of EV charging, solar PV car ports and energy storage on a new build project for a local authority
