With shorter days and getting darker earlier, LHW are now providing seasonal electroluminescence testing and inspection surveys to determine health of PV modules. This is in addition to a range of other testing services. Already offered.

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.

After a 30 year gap, LHW have added load bank testing to the range of testing services in its portfolio,

LHW are providing Technical advisory services on a number of large scale  PV-Wind hybrid projects both in UK and overseas.

Following successful PV installation of 75kWp, a local authority engaged LHW to undertake a feasibility for adoption of heat pumps at a large 85 bed education and outdoor centre. This included IR verified heat loss, and full review of ASHP, Borehole and Ground collector systems.

Though PV Farm IR surveys are not core business, LHW offer this service as part of a more integrated offering involving electrical testing at ground level. This encompasses IV Curve, Series, Shunt and Riso, as well as EL.and system performance verification.
