Carbon Trust Accreditation

Posted by & filed under Solar PV News.

T H WHITE have been awarded prestigious Carbon Trust Certification which recognises excellence in providing specific energy technology to businesses to reduce their overheads and carbon emissions. T H WHITE has been granted this quality certification due to the extensive experience in providing Solar PV to commercial and agricultural properties, specialising in professional installations that support businesses.

The process involves a rigorous technical assessment and means that not only is T H WHITE recognised officially for its special area of expertise but is now also available to offer special funding to clients interested in installing Solar PV.

The new funding is called a capital contribution, qualifying companies can access up to £5,000 towards a Solar PV project and it is eligible for use alongside the feed in tariff. To qualify we can assist clients with applications to the scheme prior to an installation and provided they meet specific criteria and are classified under the scheme as an SME.

There are some forms to fill in, we require copies of your energy bills and the application is then submitted for approval prior to start of works. The capital contribution is paid once you receive a commissioning certificate from us.

If you have a project in mind or one on the back burner you have been thinking about which didn’t stack up before, then it may be worth looking at the numbers again. Please give us a call on 01380 726656 or email energy@thwhite.co.uk for more information

 

T H WHITE attends Smarter E Europe 2018 Exhibition

Posted by & filed under News.

Remaining at the leading edge of renewable energy and smart technology requires insight and exposure to what can be at best a complex supply chain and at worst a melting pot of mixed concepts, products and services. In the UK we have seen a revolution in renewable technology adoption in all sectors and as the market models change the products continue to advance making them viable and competitive with fossil fuels in many cases with no requirement for subsidy support.
This month Energy Fire and Security Division attended the worlds largest show of it’s kind Smarter E Europe 2018 in Munich, Germany. IN attendance were 1.177 exhibitors from 49 countries in eight halls over 86,000 square meters of exhibition space and around 47.000 visitors from 155 countries. The objective was to deepen our insight, stay in touch with new innovation and strengthen partnerships with some of the worlds leading manufacturers.
The event showcased a number of key product areas: Solar PV panel and equipment manufacturers demonstrating resilience and an increased efficiency of panels (5 years ago a 60cell panel would have been around 180-200wp, we can now see a range from 280-330wp and at a much lower investment cost); Battery storage players were there, Powerwall 2 remains the most cost effective per kwp and has the highest power output however other manufacturers are developing their ranges and will catch up in the next couple of years; E-mobility is the biggest change compared to previous shows with the rapid growth of electric vehicles – there were not only chargepoints but also signs of solar players looking at innovative tie ins with solar pv. There were also a wide range of e-vehicles to test drive including e-boats, e-motorbikes, e-vans and batteries you can adapt existing vehicles.
Back in the present, the biggest takeaways from the show were the continued cost effectiveness and relevance for solar PV as a key part of our UK power generating mix. Our team have many years experience and have built some of the biggest rooftop systems in the UK and now maintain many hundreds of systems for clients.

Electric (EV) charge point

Posted by & filed under News.

April saw the installation of the first T H WHITE owned electric vehicle (EV) charge point at its head office in Devizes, Wiltshire.

A dual socket universal charger has been installed, capable of charging the majority of electric vehicles and hybrids and is designed for use on commercial premises. The EV charger has 2 x 7kw smart charging sockets enabling two vehicles to be charged simultaneously and means visitors and staff to our head office can now plug in while they visit to help top up their car or van for their next journey.

The T H WHITE EV charge point comes with a full back office system meaning the power can be purchased via a simple RFID card transaction made possible by a special MID-B energy meter which tracks the energy used and communicates to the provider via the internet. It is IP54 rated for outdoor use and comes with a smart set of bollards and tyre stops to protect the charger from accidental collision.

T H WHITE have selected a dual outlet post which attracts a grant of £300 per socket from the government OLEV grant scheme specifically for workplace chargers (there is also a residential grant scheme as well).

A few fun facts for those of us who are new to electric vehicle chargers: There are 135,000 plug in cars in the UK currently and this figure is growing; a little known fact is that electric vehicle charge points do not charge the vehicle – the vehicle on board computer controls the charge required and requests power from the charger and there are 15,000 public EV charge points in the UK (again growing).

T H WHITE are offering customers supply and installation of a full range of grant funded electric vehicle charge points including domestic products and a range of commercial products including standard and rapid charging units. Contact us on energy@thwhite.co.uk or call 01380 726656.

 

Feed In Tariff News 2018

Posted by & filed under Solar PV News.

2018 sees the final run in of the feed in tariff in the UK, which is one of the remaining subsidies available to people and businesses who want to invest in renewable energy technology like wind, hydro or solar pv.

Based on the current arrangements the tariff will no longer exist after March 2019 which means anyone still interested in tapping into this subsidy to help you pay for your solar installation will need to get on with it to avoid missing out.

The good news is that solar panel prices have dropped a lot since the feed in tariff was introduced originally in 2010. A 4wkp solar pv system now costs considerably less around £6-7k vs the old prices we used to see of £12-14k. Big price drops can be seen on all scales of solar pv which is why for high users of electricity (i.e. if you install solar and you anticipate using greater than 70% of its generation) you can achieve double digit returns on your investment without a subsidy at all!

This scenario does not apply to all people, so for anyone planning on investing in a new solar array or adding additional solar to their buildings you need to think about tapping into the feed in tariff if you have a lower electrical use in daytime.

What does the future hold for renewable energy subsidies in the UK?

It is difficult to say with any certainty how much renewable energy will be deployed under the current government on certain technologies as there has been support for off shore wind but a mixed effort to support on shore wind and solar in recent times. That said, solar pv cumulative installations are still growing, it is one of the most popular technologies in the UK by a long way and looking at the global picture solar is expected to be the biggest power source in the world for electricity generation in the future. With grow and scale comes better pricing and more research and development and cheaper and more efficient cells. The future will have no subsidy for renewables as they are already proving they are competitive with dirty fossil fuels which are now being phased out.

Should you wait to invest?

Our advise is no, solar is established, affordable and easy to install and one of the most reliable power sources of any kind. We have shown you a picture of our solar generation yesterday at our HQ in Devizes in this article showing we are self sufficient on a day in January. Solar is a powerful tool and cuts your overheads almost immediately, it is also the perfect partner for battery storage which is technology you should watch and think about next.

Smart Meters for Solar and Battery

 

January saw the installation of a new Smart meter which monitors the solar we generate and the power we use at our Energy Fire and Security HQ in real time.

The beauty of this smart meter is that it’s really easy to use, we have connected it to our electricity supply and solar system and can view the information on a web portal and on display in our reception. T H WHITE can now view how self sufficient we are with our new 248kwp solar system, we expect for many days in the year we will be 100% self sufficient and now we can prove it even easier than before.

 

 

 

 

 

 

 

 

The data from the smart meter is presented in a nice easy to understand display on screen where you can see exactly how much you are generating and using from either solar or the grid – it gives you a measure of how self sufficient you are at any time. For the real experts you can also attach pyranometers to monitor the available sunlight and compare that to your generation.

Aside from showing self-sufficiency information the data can also build up a picture of what benefit you might be able to get from adding a battery to store power and use it when you need – this could help some solar owners from being partly self-sufficient to 100% self-sufficient and at the very least let you use more of that lovely cheap sunshine to cut your bills!

We are now able to offer this device to all our solar clients and also clients who have no solar but are considering either solar or battery solutions for their properties. For a quote please email energy@thwhite.co.uk or call 01380 726656

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 charge points

Posted by & filed under News, Uncategorised.

T H WHITE now offer electric vehicle (EV) charge point 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 charge point 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.
