New T H WHITE HQ Solar PV System

Posted by & filed under Solar Case Study, Solar PV News.

September saw the big switch on of our fourth T H WHITE solar system on one of our own buildings, this time on our new Nursteed Rd campus for the Energy Fire and Security, Cranes and Projects Division buildings.

The system was design and constructed by our own solar engineering team using solar panels and inverters from our partners Hanwha Qcells and Fronius respectively.

In total the system uses 928 solar panels and has a peak output of 248.48kwp, able to generate over 232,000units of electricity a year.

We expect the system to provide enough electricity to make the buildings self-sufficient in some months of the year and overall make a significant dent in our electricity overheads.

The system will save 80 tonnes of Carbon a year alone which is important for our ISO50001 and ESOS energy management accreditation as part of a range of measures we have incorporated in our renovation of the site which has included new insulated roof panels, low energy lighting, high efficiency gas boilers, PIR lighting controls, energy efficiency glazing.

T H WHITE Energy Fire and Security are still active installers of solar systems and we provide a comprehensive range of solar maintenance and cleaning services. Call us on 01380 726656


Solar Panel Cleaning

Posted by & filed under Maintenance News, News, Solar PV News.

Solar Panel Cleaning For Improved Yield


The UK now has over 750,000 solar installations and people have witnessed first-hand the stable income and savings it can generate. As the years go by solar panels will continue to generate and like every piece of infrastructure there are times when they need a check up and a clean to keep them generating at their optimum potential.

T H White’s energy specialists have been involved in thousands of solar projects and after seeing an increase in demand from customers for our maintenance services we have now expanded the range to include solar panel cleaning.

Our trained staff use specialist cleaning equipment which we have taken time to test and review to ensure it complies with solar panel manufacturers warranty requirements. Solar panels come with a 25 year performance guarantee, provided they are operated and used in the correct approved way.

Why clean solar panels?

As part of our annual inspection we recommend a visual inspection of systems and in the first year we recommend checking quarterly to make sure you are monitoring the site for dust and dirt build up. Some businesses have very high levels of dust which may mean cleans more than once a year. Similarly someone with a heavily wooded area may have leaf litter build up which can impede solar pv performance as well.

Clients who have had arrays cleaned within the last year have experienced yield increases of over 10% from having their solar systems cleaned.

We are able to clean all sizes of roof-mounted solar systems except for extreme hi-rise buildings and also tend to small to medium ground mounted systems. Depending on the size of building we can either clean from ground-level, attached to mansafes and harness or via other mechanical access equipment.

If you have a solar system all we need to know is the system size, approximate size of building and if there are any access requirements we may choose to visit the site to provide a quote.




New 250kwp Solar System

Posted by & filed under News, Solar PV News.

Work has started on T H WHITE latest solar pv array in Devizes. This is the fourth solar system the T H WHITE Group has invested in and will power up the Energy, Fire and Security, Lorry Cranes and Projects Divisions.

The system is using 270w high performance Hanwha Q-Cells polycrystalline modules, Renusol and K2 frame and brackets along with Fronius Symo inverters.

We have chosen the products for this installation based on their proven track record for this kind of installation and strong guarantees. T H WHITE has traded for over 185 years and has to ensure it selects products for long term performance and we apply the same rules and criteria that we would recommend to our customers.

The Hanwha modules have a strong 25 year linear performance warranty offering a minimum of 83% of performance capacity at the end of the 25 years. This is really important for solar investors as solar panels can operate successfully for a long time and if anything were to go wrong T H WHITE is more likely to be around than most and therefore needs to be able to rely on their partners to be there too to honour the guarantee.

Electric vehicle chargepoints

Posted by & filed under News, Uncategorised.

T H WHITE now offer electric vehicle (EV) chargepoint installation as part of our range of specialist building services. The systems include domestic and commercial solutions and are installed by our own in house engineers.

We have trained staff to ensure we are compliant with the new regulations concerning this new type of EV chargepoint technology and this has also enabled us to be able to offer clients government OLEV grant funding for qualifying residential or commercial installations to help pay for them.

The UK government has serious ambition to ensure all new vehicles will be ultra low emissions which includes electric vehicles or EVs. EV’s have been growing quickly in recent months and only recently the EV market grew by 20% in January 2017, far outstripping the conventional petrol and diesel fuelled markets. There are some recent media forecasts openly discussing 80% of new vehicles being Electric vehicles by 2050 and the Queen’s Speech this week indicates a clear sign that the government is backing this important trend.

With such growth of electric vehicles (ev’s) predicted to continue more and more commercial and public buildings will require electric vehicle chargepoint infrastructure as will the homes of the drivers who own them. T H WHITE will be able to offer a range of devices to cover the range of vehicle brands, charger solutions, charger speeds, voltage sizes, breaker sizes, physical site requirements, site specific safety requirements for individual or multiple installations of EV chargepoints.

174.4kwp Commercial Solar PV South East

Posted by & filed under Case Study, Commercial Case Study, Solar Case Study.

2014 saw the completion of one of T H White Energy, Fire and Security’s most prestigious commercial rooftop solar PV installations with 174.4kw of Commercial solar pv in the South East of the UK with Remet UK.

Remet UK are a materials technology provider that specialises in materials for the precision Investment Casting Industry. When relocating to a new manufacturing site it was important to minimise the carbon footprint and reduce energy costs. This was to be achieved by the installation of a solar system. The system will also provide a good level of return on investment.

The installation was part of a major retrofit of the electrical connection for the site as Remet UK were refurbishing the site. The building is a considerable size and close to the coast in Kent, requiring considerable safety planning of access, scaffold and rescue planning for working at height. T H White handled the complete installation from start to finish with our traditional turnkey approach including design, procurement, project management, roofwork, CDM planning and site management and electrical installation and commissioning.

The PV system itself uses highly bankable Hanwha QCells 260w solar pv modules with their powerful warranty and decades of high grade solar cell manufacturing quality, Renusol Mounting system and two Fronius Agilo 75kw central inverters. The Fronius Agilo central inverters are high efficiency commercial grade inverters building on the pedigree of Austrian manufacturer Fronius family of inverters which has had many years of experience in the UK solar market and the system is fully remote monitored.

Remet UK are setting a great example for other commercial property owners and manufacturers looking to reduce carbon emissions and lower their overheads and with the strong sun hours in Kent they are set to see some of the best solar pv yields in the UK.
