Smart Solar has profiled RenEnergy and Q-Cells’ recent solar installation at Natures Menu: the largest pet food manufacturer in Europe.

You can read the full piece online here.

Here’s a taste of the article from Smart Solar…

“British renewable energy developer RenEnergy has built Europe’s largest flat rooftop solar installation to use Q CELLS’ Q.FLAT-G5 mounting system – a 522 kWp array at the site of quality pet food manufacturer Natures Menu in Norfolk. The array will also utilize 1,608 Q.PEAK DUO-G5 modules.

Q CELLS, solar cell and module manufacturer, supplied its award-winning Q.FLAT-G5 mounting system and Q.PEAK DUO-G5 solar modules to British clean energy developer RenEnergy for a commercial rooftop in Norfolk, UK.

The 522.6kWp array was constructed at the main production facility of Natures Menu, a British producer of high-quality pet food. This solar system is the largest in Europe to be built using Q CELLS’ Q.FLAT-G5, and generates solar electricity using 1,608 Q.PEAK DUO-G5 modules.

Allied to a growing appetite nationwide for clean, renewable energy and greater energy independence is the simple fact that solar PV components are becoming more and more affordable by the day. The pet food production facility of Natures Menu will self-consume the solar electricity generated by the 522 kWp array.”

We spoke to the EDP about our solar carport for Aviva’s Horizon building

RenEnergy’s first solar carport project has gained media exposure in local newspaper, the Eastern Daily Press.

We spoke to EDP journalist, Caroline Culot, ahead of our open day at the Aviva Horizon Building in July. Her short piece covers the scope of our solar carport project, and why generating sustainable energy on-site was important to Aviva.

Here’s an excerpt from the article:

“Across the course of a year, this system will provide more than 32pc of the site’s total energy demand, representing a carbon offset saving of 166.5 tonnes per year, and a major contribution towards Aviva’s efforts to tackle climate change.

In 2006 Aviva became the first carbon neutral international insurer, and is working towards a 70pc reduction in operational CO2 emissions across the whole company by 2030.

Stuart Wright, property and facilities manager at Aviva said:

‘The solar carport is a really innovative way to generate green energy, tackle climate change and reduce our environmental impact. It’s a fantastic design that delivers on the environmental benefits without impacting on space.’”

Thanks to EDP for the write-up, and to Aviva for collaborating with us on the open day event.


RenEnergy shortlisted for Solar & Storage Live Awards 2019

Solar Power Portal: Solar & Storage Live Awards

We’re pleased to announce that RenEnergy has been shortlisted for Solar Power Portal’s 2019 Solar & Storage Live Awards! Our solar carport project for Aviva is up for Commercial Project of the Year Award.

Covering 250 parking spaces at their Horizon building in Norwich, Aviva’s solar carport will generate 542,000 kWh of electricity per year. That’s enough to power 138 homes. The installation saves 166.5 tonnes of CO2, and allows the building to be 100% off-grid and during peak hours. Aviva is committed to staff happiness, so it was essential we completed the 13 -week project with minimal disruption. Aviva became a carbon neutral insurer in 2006, and the carport is a further example to the firm’s environmental corporate responsibility. Click here to read our Aviva case study in full.

The solar carport we installed for Aviva is one of the largest in the UK, and this shortlisting is a testament to the hard work our team put in to execute this project.

We wish the best of luck to all firms shortlisted in the Solar & Storage Live Awards. We’ll see you at the awards ceremony in September!

RenEnergy wins Cranfield University Solar PV contract

RenEnergy has been awarded the design and build contract for a 1 MW solar photovoltaic (PV) array at Cranfield University, Bedfordshire.

The project will be fully funded by the University, without any government support through the ROOFIT scheme, making this one of the first and largest subsidy-free renewable energy schemes in the country.

Damian Baker, RenEnergy MD said: ‘We are delighted to have been appointed as the solar PV contractor for such a prestigious institution. The University’s reputation for world class engineering and project management education aligns perfectly with our own values for the deployment of high-quality renewable energy solutions.’

The ground-mounted array will be situated at Cranfield Airfield, adjacent to the University’s main campus, feeding the generated energy directly into the sites 11 kV network via private wire.

Solar PV will contribute over 5% of the sites annual energy demand, not only furthering the carbon saving efforts at the University, but also providing a key renewable energy research facility for the students.

Feargal Brennan, Cranfield’s Director of Energy and Power, said: ‘Cranfield has a reputation for providing students with the opportunity to use industrial-scale facilities for education and training support. The solar farm will not only provide a new facility which can be used by students but also a sustainable, reliable and affordable energy supply to the campus.’

Key suppliers:

  • PV Modules: Hanwha Q-Cell – QPLUS 285w
  • Inverters: Fronius ECO & Symo string inverters
  • Ground mounting frame: Hi-Span
  • Transformer: Wilson

The 3,508 solar panel installation will cover an area of two hectares to the east of the main runway, and generate approximately 1,000 MWh of energy per year, sufficient to power 300 homes.

Damian Baker said: ‘We are all facing energy challenges as we try to balance the demands of growth and sustainability. Solar integrates well into existing infrastructure to provide a clean, cost-effective, long-term power solution, as is the case at Cranfield, where our solar array will interact with the combined heat and power (CHP) plant onsite to provide energy without exporting to the grid.’

Integration with the existing energy infrastructure was a key engineering consideration at the tender stage, further complicated by an export limit of 0 kW imposed by the DNO. Fortunately, RenEnergy were able to call upon extensive experience of similar projects to design a viable and cost effective solution.

Gareth Ellis, Energy & Environment Manager said: ‘The University is committed to renewable energy and the installation of the PV panels will improve our carbon footprint. Cranfield already has a CHP on site producing 60% of their electricity. We have made significant reductions in carbon emissions in recent years and are well on our way to achieving our target of a 50% reduction by 2020 against our 2005 figures.’

How to spot fraudulent activity

In September we posted an article titled “A new scam taking place”. It highlighted that companies were phoning PV system owners to sell products and services to stop their system catching on fire.  We wanted to make sure that our customers knew this was incorrect.

Since then, companies have become more imaginative and have created other stories and scenarios to get you to buy their “service or product”. Examples of this are inefficient inverters, inverter health checks, panel failure and potentially many more. We at RenEnergy do not want you to pay out money to these companies to not receive the service you pay for and do not need.

We have put together some tips to spot if the company is fraudulent:

  1. Has the company contacted you? Always think why and how a company has your details? We never hand out customer details out to third parties so if a company says that they have received your details from us then always be suspicious.
  2. How does the company know about your system? If they are talking about an inverter issue how do they know what your inverter is reading? Often they are placed in a loft or out of sight place and would only be read remotely by yourself or your installer.
  3. Do you recognise the company name? Ask for their name and details and do a Google search. Often the companies we have seen are registered with the government’s Company House data base, but there is no website and the details are very vague. Any scam reporting may be highlighted too.
  4. Have the Energy Savings Trust heard of the company? If you are still unsure call them and see if they recognise the company. They will often give a number of a local reputable company you can call.
  5. What do the installers of your system say? Always phone the installers of your system, or they are no longer operating you can call us, to ask if we can give anymore information. With years of experience we will know if the enquiry is correct or if we think it is a scam.

Always stay aware and don’t agree to pay for any product or service that you are unsure about. It never hurts to get a second opinion even if it is genuine.

If you are unsure and would like to talk to us we can be contacted on 01603 713448 or

Lastly, if you still want your system to be checked over give us a call and we can give you more information, and whilst we are out there explain how your system works.

Is subsidy free solar viable?

The government definitely thinks so. How about industry experts? Again, many believe it is.

Abid Kazim, the MD of NextEnergy Solar Fund, is passionate that solar can indeed be subsidy free, if, as he pointed out in the opening session of yesterday’s Solar Finance and Investment Europe event, the government “get out the way”.

Kazim starts off with saying how the solar industry has changed and that it had “entered a period of enlightenment”.  Down playing the cost of panel prices, development costs or finance being the main barriers of deployment but instead went on to say that counterproductive policies and regulation red tape were the largest issues. He issued six required changes that would need to enacted if the UK were to let subsidy free solar thrive:

  • A reshaping of the regulatory framework to reflect how low carbon technologies are approaching grid parity;
  • The abolishment of Contracts for Difference;
  • The establishment of long-term PPAs so that carbon intensive and low carbon technologies can compete on a level playing field;
  • The re-categorisation of batteries as energy storage;
  • Introduction of a regulatory framework to manage the pace and cost associated with a shift to a totally self-regulated decentralised energy system, and;
  • A carbon pricing model within a ‘polluter pays’ framework where the levies of energy supply companies are not passed onto consumers.

Kazim also said that in order to keep the energy market fair there must be a carbon price paid by the utility companies that is not passed onto the consumer.

Today is the last day of the Solar Finance and Investment Europe. We look forward to seeing what The Solar Power Portal have to report and how many other experts share this opinion.

2018 Energy Trends

Last week the guardian posted an article on five renewable energy trends to watch in 2018, and here is a summary of what they are:

Renewable energy costs will continue to fall

Since 2009, solar prices have dropped by 62 % and off-shore wind by 50 %, reaching £57/MWh. Record low prices for both solar and wind at power auctions have made way for subsidy free energy. This trend is predicted to continue, with decreasing prices in India creating better competition in auctions.

China will push ahead with its ambitious energy plans

Contradictory, China is both the world’s biggest polluter and the global leader in solar generation. In 2017, China expected to install a whopping 54 GW of solar, surpassing their targets for 2020 already. By 2020, China plans to have invested £292bn in renewable power and to introduce a cap on the amount of coal burning that has caused severe air pollution in many of its cities.

China have eight large-scale carbon capture projects underway, plan to be the global leader is electrical vehicle manufacturing and adoption, and have finally introduced its national emissions trading scheme which put a price on the carbon emissions across the Chinese power generation sector.

Corporations will make bold commitments 

Many companies are pledging to become RE100 companies, where 100 % of their energy come from renewable energy, joining the likes of Apple and Goldman Sachs.

Experts expect that the number of corporations pledging ambitious renewable targets to increase in 2018, mainly due to the prices of renewables falling and corporations being exposed to climate change and NGO campaigns.

The renewable industry will generate more jobs

The International Renewable Energy Agency released a report stating that 9.8 million people now work in the renewable sector worldwide, with wind turbine service technician and solar PV installer jobs becoming the fastest growing occupations in the US. Here in the UK, jobs should be created thanks to the £17.5bn invested in offshore wind.

To keep up with the increasing uptake of renewables there needs to be an increase in skilled workers, otherwise the speed of energy transition will be limited.

Competition in the battery market will increase

In 2018, Tesla will complete is Gigafactory in Nevada. In 2021, China plans to install 120 GWh capacity of battery cells.

In the UK? In April 2017, the Faraday Challenge was introduced. This is the first phase of £246m investment in battery technology designed to boost research and development, hoping to put the UK at the forefront of the energy storage market.

There is also a prediction that pumped hydro storage,compressed air storage, hydrogen storage, solid state batteries and water based batteries will all see a growth in 2018.


So there you have it, 5 renewable energy trends of 2018. Watch this space.

The future of FiT

Last month the government published their Autumn Budget 2017, which not only mentioned that renewable energy levies will be cut (see our previous post) but it also confirmed that the Feed-in-Tariff (FiT) will close to new accreditation at the end of March 2019.

What is the FiT?

For those of you who haven’t heard of the FiT we will give a small summary.

The FiT is a support mechanism provided by the government to encourage the uptake of various renewable energy generation. It is limited up to 5 MW and is split into tariff levels. The owner of the power supply is paid for generation of electricity and for any export to the grid. For more tariff details click here.

The scheme was introduced in April 2010 and has since seen both households and businesses become very large investors in renewable energy. A whopping 808,051 installations were accredited to the scheme by 30th November,  which equates to 5,868 MW of electricity.

What’s happening right now?

As the scheme moves into its final stages the tariff is decreasing each quarter, which could be why many forecasts reveal a slump in new installations. Cornwall Insight noted that  Q3 2017 had 90 MW accredited, which is the lowest in any quarter since Q2 2011, and 5,662 installations, the fewest in any quarter since Q2 2010. Other reasons for the decline in uptake is that many technology types now fall under the quarterly deployment caps set by BEIS. Since Q4 has begun (October-December) only 20 solar PV installations have been accredited, in comparison to 2,116 in September alone. Further echoing this decline is that for the first time ever hydropower had more accreditation in October than any other technology type.

What does this mean for the future?

Predictions based on historical data show that electricity demand will be lower than original predictions showed and that uptake in the FiT accreditation will also decline. After March 2019 there will be no more new applications, however, the majority of projects who have benefited from FiT will receive payments for 20 years after the commission date. This means that the first projects to receive the subsidy will do so until 2030.


Are the UK’s birds being confused by a changing climate?

We are seeing the effects of climate change all around us and we all know we need to do our bit. New evidence shows that climate change is affecting the behaviour of our migratory birds. Birds are arriving more than 20 days earlier than they did in the 1960’s, according to the state of the UK’s birds 2017 report. One example is the swallow. Swallows are now arriving 15 days earlier than they did 50 years ago. If climate change continues we needs to predict the future effects on birds and other wildlife.

This may not seem like a massive issue to many, but the report warns that there will be winners and losers, with some opportunities for some birds but higher extinction risks for others. For example. the night heron are now breeding in the UK, whereas the snow bunting are declining. In addition, these changes in behaviour mean that there could be a discrepancy between the time that chicks need to be fed and the food that’s available, meaning they may be less successful in their breeding.

Dr Stuart Newson of the British Trust for Ornithology (BTO) said thousands of volunteers have submitted observations over many decades to show how birds have responded to climate change. He urges that “ongoing monitoring is essential if we are to track the future effects of a changing climate on our birds.”

Collatte Hall, from Wildfowl and Wetlands Trust (WWT), has said “We also need to look beyond the UK and make sure that the protected site network continues to cover the right places throughout Europe and that they’re monitored elsewhere as thoroughly as they are in the UK.”

If you would like to know how your business or home can help reduce the effects of climate change by installing renewable energy solutions then talk to us at RenEnergy. After all, we only have one planet and we all need to do what we can to save it.

How the 2017 Budget will affect the solar industry?

On Wednesday we tuned in to listen to the budget announcements made by Philip Hammond.

We all got excited by the promises of stamp duty relief and funding for electric vehicles. However, there was no mention of energy policies for low carbon electricity. What Hammond neglected to mention was that the government will not provide any further levies for low carbon electricity until 2025. The government has said this to protect consumers from any further burden caused by levies and their impact on energy bills.

The Office for Budget Responsibility (OBR) have revised down its forecast for environmental levies. It now expects spending under the Levy Control Framework (LCF) to fall a further £0.2 billion to £0.3 billion a year in 2020/21 and by £0.5 billion a year in 2021/22. This is made possible by the reduced spending under the Renewables Obligation and Contract for Difference schemes.

The OBR’s reduction in CfD costs stems from a higher projection for wholesale energy prices,  reduction in the total subsidy costs paid to contracted generators and cheaper than expected contracts.

Within the budget the government outlined multiple assumptions. Within these assumptions were the forecasted deployments of different technologies under the various subsidy programmes, such as RO, CfDs and FiTs. The government has forecast that 200 MW of small scale, FiT-accredited solar to be installed in this financial year, with a further 240 MW in the forthcoming year. These forecasts are up to the closing of the FiT scheme, which is set to close to new applicant on 1st April 2019.

This would leave a significant amount of unused capacity within the feed-in tariff deployment caps, currently totalling more than 200 MW. A review of the FiT scheme is yet to be scheduled, but the department is committed to conducting the review before the end of this year. The parliament rises for recess on 21st December, which means the review should enact soon.

The wording of the government’s set of levy controls means that it is opposed to enacting new levies for low carbon power generation but it has opened the door for support frameworks which do not add to subsidy costs on the consumer bills.


How a Solar PPA Can Benefit Your Business?

banner of commercial solar PV webpage displaying solar farm

You may have seen that many businesses have invested in solar energy.

Why? Solar energy is a great way for your business to reduce its electricity bills, obtain energy security in the future and reach its Corporate Social Responsibility.

You may have looked into a solar power system for your own business for those very reasons but do not have the capital available. At RenEnergy we believe that this should not be a barrier and have a Power Purchase Agreement (PPA) to help your business.

What is a PPA?

A Power Purchase Agreement relieves your business from needing to find the capital for an upfront cost. Instead RenEnergy funds and owns the system. We simply lease the roof off you and maintain the system for 25 years.

You purchase the electricity from us, but only what you use, at a rate that is cheaper than you are currently paying.

For example, if you currently pay 14 p/kWh you may have a PPA of 11.2 p/kWh. Saving you 20 % off your current electricity price, without having to pay any extra!

What happens in the future?

We own the system for 25 years, selling you electricity at a low price that has been agreed between both parties.

After 25 years you own the system and generate electricity that is directly used by you, with no more costs to pay.

If you move premises or are no longer operating with in the next 25 years you do not need to worry! The lease is fully transferable to the new tenant of the building.

I’m interested! What shall I do now?

How Changes To Network Costs Could Affect You?

On Monday Ofgem provided an update on its targeted charging review. But, what does this actually mean?

Ofgem have published two separate documents alongside a blog outlining potential charges to the way the regulator recovers both forward-looking and residual (historic) network charges.

Currently, Ofgem bases residual network charge recovery on a household’s net consumption. This means that customers with rooftop solar PV or battery storage reduce their reliance on the grid and therefore pay less. The cost is therefore passed on to those who solely use the grid, in order for the grid to be maintained.

Andrew Wright, the author of the blog, wrote “We want to make sure that all users pay a fair share of the costs even if they are only using the networks when their onsite generation is not producing electricity.”

The regulator has put forward four separate approaches for how these charges should be recovered from final demand:

  1. Volumetric Basis – Based on the units of electricity used in kWh. This is Ofgem’s current method of recovery of residual network charges of the distribution system.
  2. Capacity Basis – Separated into ex ante capacity and ex post capacity demand charges. This is based on either the user’s agreed or connected capacity or peak system use.
  3. Fixed Charges – Customers are separated into user profile classes, with each class allocated a fixed charge determined by Ofgem to share residual network costs.
  4. Hybrid Approach

The regulator has elected to bring forward fixed, ex ante capacity demand and ex post capacity demand charges for further assessment.

So what is ex ante and ex post capacity demand?

Ex Ante – Based on the user’s agreed or connected capacity, with consumers possibly incentivised to declare their capacity needs. Ofgem have said that any forecasts issued could be used to support planned of network demand.

Ex Post –  Peak use would be measured, and a charge based on the average of a set of number of each user’s highest usage half-hours over a defined period.

Ofgem’s stated aim is to progress rapidly through the process, hold two rounds of stakeholder events throughout the rest of the year and release a consultation on its announced minded-to-decision by next summer.

Over the next year we will find out exactly how these changes will affect you and your electricity bills.

Two stakeholder sessions have been scheduled, one in Glasgow on 15th November and another in London on 30th November. Ofgem can be contacted by those interested in attending at:
