Joju Charging scoop EVIEs ‘Contractor of the Year’

We’re proud to share that last week, we won Contractor of the Year (C&I and Public) at the prestigious EVIEs, for the third time in four years.

The Electric Vehicle Innovation and Excellence Awards recognise the very best in the EV industry, and it’s an honour to take home the title again this year.

In 2023, we’ve installed lots and saved tonnes! 

According to Zapmap, this past year we’ve installed 14% of all public charge points – a mix of fast and rapid chargers in public car parks, and on-street infrastructure. We’ve saved 4,000 tonnes of CO2 and 48 tonnes of NOx. We’ve supported Hammersmith and Fulham to expand their on-street network. Every resident is within 400 metres of a charge point and EV ownership has increased by 67%. Our work with Dorset Council has helped to put them in the top 20% of areas for charge point availability and as well as infrastructure for residents/visitors, we’re helping councils transition their fleets so community services are powered by renewable sources. This is critical for improving air quality and reducing CO2.

We specialise in infrastructure for atypical vehicles. A standout partnership has been working with Islington Council at their Waste Recycling Centre, and 10 other sites in the borough. The council’s ambition is inspirational, and we’ve now electrified over 70 bays for use by buses, waste trucks, tippers and other vehicles. All works took place with zero operational disruption.

We’ve further developed EV Charging Infrastructure across sensitive operational police, ambulance, fire stations and control centres. We’ve supported more workplaces with EVCI, to encourage EV uptake this year. We’ve also helped public and private sector organisations maximise underutilised spaces by installing solar car ports, to charge vehicles and power buildings.

Our first-of-its-kind ‘EV Insights’ group is now 3 years old, and it facilitates the pooling of best practice.

On social media it’s been said that we stand out by being “in it for the right reasons”. Our mission is to help communities, homeowners and workplaces cut carbon, and that will always be the case.

The reaction

Joju’s CEO, Joe Michaels, said:

“It’s a genuine honour for Joju Charging to win Contractor of the Year at the EVIEs for the third time. Once again, the credit goes to our hardworking team. Their passion for helping public sector and commercial organisations achieve their net zero carbon ambitions is second to none. We also want to say a huge thank you to our clients, customers, and partners, and congratulate our clients Islington Council and the Borough of Hammersmith and Fulham, who received shortlist recognition”.

Joju’s Head of EV, Graeme Patton, also commented:

“It’s amazing to win Contractor of the Year for the third time in four years, and it really is testament to the hard work of our teams, who are always looking for ways to continuously improve and lead the charge every day. To make the shift to electric vehicles people need more EV charging infrastructure, and helping the public sector deliver this is at the very heart of what we do… whether it’s helping local authority fleets transition, or providing more public charge points. It’s great to be recognised for the quality and innovation of our design and delivery across the board, from councils to commercial workplaces”.

Prioritisation and myenergi products

myenergi, who make the zappi smart EV charger and eddi hot water diverter, have made their products compatible and configurable with batteries.

Why is this good news? Well, not all smart EV chargers and solar hot water diverters are compatible with home battery storage, and using incompatible products can lead to odd things happening with your setup. You may find your home battery is discharging surplus energy into your hot water tank when you don’t want it to, for instance!


Getting your priorities right

The main products that can be installed alongside a solar array all perform a similar function. They control the storing of solar energy for use later on.

Home batteries divert surplus solar into a static battery wired to your house for use at night.

Smart EV chargers divert surplus solar into your car battery or can fast charge.

Hot water diverters divert surplus solar into your hot water cylinder with various boost options.

Which bit of kit gets the energy first though, and why? Well, when we install your system, we set up the prioritisation in the following way:

  1. Home batteries

Home batteries provide power to your house when your electricity is at its most expensive so we set the home battery to be charged first from any surplus solar. If you don’t use much power at peak times, that’s OK… the batteries will fill up quickly and then your solar can power the next item on your priority list. It’s also self-regulating so once it’s set up, you can leave it to do its thing!

2.  Smart EV chargers (like zappi)

Smart EV chargers can be set to charge your car at full power, or just with surplus solar. For us, the car is second on the priority list because you’ll probably have the option of charging your car on a cheap electricity tariff at night, at full power. Even if you don’t have a cheap night-time electricity rate, it’s still wise to charge at full power after midnight. This way, the car charges from surplus solar in the day (if there is enough surplus solar) and if a top up is needed, it comes from the battery at night. The system is self-regulating and you don’t need to think about it, or make any predictions on a daily basis.

 3. Hot water diverters (like eddi)

These are set to come on after your home battery and car battery are full, or if your car is not at home and plugged in. They should be the third priority because there are normally two cheaper ways to heat hot water. Your boiler or heat pump will be cheaper per kWh than electricity during the day. Also, you may have the option of heating hot water at night on a cheaper rate.

If you heat your hot water with a gas boiler, fitting an eddi will reduce the amount of gas you consume. The gas boiler should be on a timer to heat your water early in the morning as well as later at night when the sun goes down. Surplus solar will heat the tank in the day. If it’s not that sunny, the boiler will make up the difference. As with the smart EV charger, it’s self-regulating and will automatically adjust for different amounts of sunshine and electricity usage.

If you heat your water with a heat pump, it works in a similar way to a boiler. The heat pump uses 1 unit of electricity to make 3 – 5 units of heat, so it’s cheaper than using direct-acting electricity during the day. Heat pumps also heat water on a timer, so surplus solar can be diverted to a cylinder in the day and the heat pump can make up any difference in the evening and early morning.


The difference between Eco and Eco+ on zappi

If you’ve got a zappi, you might have noticed the ECO and ECO+ settings. Here’s the difference between them.

  • ECO: Your zappi will detect when surplus solar starts going to the grid and divert that to the car. As zappi needs at least 1.4 kW to charge the car, with this mode it will top up the difference all the way to 1.4 kW. The difference will come from either the battery or the grid.
  • ECO +: Your zappi will detect when surplus solar starts going to the grid. On ECO + mode, the zappi will only start to charge the car once there is more than 1.4 kW surplus solar. This means that only free solar energy is charging the car. It will take longer to charge the car, but it will be 100% free. Some solar will be exported to the grid (when the surplus is less that 1.4 kW) but as long as you have set up your Smart Export Guarantee (SEG) and get paid for exports to the grid, this can be a positive.

Also, if your zappi is set to ECO+, eddi with take surplus power up to 1.4 kW until zappi kicks in to charge your car.


Setting your own priorities for batteries, zappi and eddi

If you’re installing the kit yourself, or if it’s already been installed by another contractor without any prioritisation set, here’s how to do it and remember, all methods for setting priorities are done on the myenergi products rather than the batteries.

  • Select “avoid drain” in the zappi or eddi menu. This avoids draining the battery via either the zappi or the eddi. For this to work, Joju installs a CT clamp (or sensor) on the battery AC cable.  It’s also possible to choose “avoid drain and charge”. This avoids charging the home battery until your EV or hot water is fully charged, although that wouldn’t be our best advice. The other option is to set a 20 second delay in eddi or zappi settings before it starts diverting surplus solar. It’s not always possible to fit a CT clamp round the AC cable supplying the battery (for instance if the battery is DC coupled). If there is no battery CT then the delay will allow the battery to fully charge. When the battery is fully charged and there has been a consistent export to the grid for 20 seconds, eddi or zappi will start to divert surplus solar power to the hot water tank or EV respectively.
  • There are two ways to set priorities for zappi and eddi


  1. Using the app

Touch on the eddi icon and draw it anti clockwise to below the zappi icon. This will also change priority and make zappi priority 1.

  1. Using the hardware

Go to the leader (or master) unit which could be zappi or eddi. Go to other settings, advanced, linked devices, devices and give zappi priority 1 and eddi priority 2.


The kit itself – are zappi chargers worth it?

If you have solar or are thinking about getting solar panels in the future, then zappi is definitely worth it. They might be slightly more expensive than a dumb EV charge point but offer brilliant savings by varying the amount of power that goes to your car, depending on how much surplus solar there is. For typical solar installations, it will be possible to run an EV on pure sunlight for much of the year.

As mentioned, zappi is also compatible and configurable with home battery storage.


Are eddi hot water diverters worth it?

eddi is a fantastic bit of kit. Here’s our view on when it works best for you:

  1. When you have lots of surplus solar that would have gone to the grid
  2. When you don’t get paid much for exporting to the grid
  3. If it’s expensive to heat water in other ways
  4. If you want to be as self-sufficient as possible
  5. If you like new technology and want to tinker by linking to variable tariffs (e.g. Flexible Octopus

eddi isn’t the best option if:

  1. You have a small solar array and most of the energy is used by the property as soon as its generated, because eddi will be idle for most of the year
  2. You have a medium sized array that generates roughly what you consume in a year, as well as a battery. Most of the surplus energy will go into the battery so eddi will be idle for much of the year
  3. You get a good export tariff that is more than you pay to heat your water. Some export tariffs are pretty good now, so it may make sense to allow surplus solar to go to the grid, get paid for it, and heat your hot water in the normal way.


 Linking myenergi products to smart tariffs, like Octopus Agile

We’re often asked if zappi and eddi are capable of linking to smart tariffs like Octopus Agile, and the answer is yes!

These tariffs track the wholesale price of electricity. Prices per kWh can go very low and even into the negative, which means Octopus pay you for using electricity at certain times. zappi and eddi can be set to charge when the price goes below a certain level you set. This technology has fantastic potential to help stabilise the grid and save you money and will be even more important as we get more renewables installed all over the country.

Last winter the National Grid spent £10 billion balancing the grid. This technology, which is already installed in thousands of homes could be your route to receiving some of that. You’ll be charging your car and heating water when there is a surplus of renewable energy on the grid as a whole. This could be from offshore wind or large, ground mounted solar arrays.  However, we don’t recommend relying on this feature alone to justify investing quite yet, unless you’re someone who loves to tinker! It’s not well supported by either Octopus or myenergi at this stage. In addition, Octopus say:

Our smart products are 12-monthly tariffs, and they can and will be updated from time to time. That’s why we don’t recommend relying on any one tariff to justify an investment in technology such as home battery storage or electric heat and hot water systems over many years.”

Solar car ports – time for under-utilised space to shine?

Making use of under-utilised space to reduce carbon emissions in the commercial or public sector is one of the areas we’ve been exploring. More specifically, how installing solar car ports in car parks can demonstrate a link between renewables and electric mobility – and help towards the achievement of sustainability goals.

An increasing demand

At Joju, we’re seeing an increasing demand for integrating EVCP provision with renewables, especially solar. We’ve joined forces with Flexisolar on two recent projects, to help create solar car ports that reduce carbon emissions and that can power EV Charging infrastructure.

A space reborn in Coventry

In 2022, Bourn (previously known as Sherbourne House), was repurposed as a workspace and destination. It’s form and functionality was refreshed, with the core values of this six-storey, 90,330 sq ft building being “to encourage and support behaviours which are good for its people, the place and the planet”.

That was according to Rob Hemus, Asset Director for IM Properties, and the solar car port is certainly part of the “planet” piece. The car port structure houses 36 double bays and is topped with 228 PV modules, giving a total installed capacity of 94.62kWp. The system is connected through the floor, with the inverter housed below the structure, and the predicted CO2 emissions avoided are 37,066 kg/year.



Solar for South Staffordshire Council

South Staffordshire District Council also took the plunge, with a 40m long solar carport installed at their offices, over 10 existing parking spaces. The ‘V’ leg structure features a 32.175kWp PV system including 99 panels, a Solis inverter, and an estimated annual energy generation of 26,963 kWh. The car port compliments the installed EV Charge points by offsetting onsite electricity demand, and we have more car port installations with similar goals happening in 2023.



To top it all off…

Talking of under-utilised space and car parks, a very different approach was taken by our client, Rotherham Metropolitan Borough Council. The Council set aside the top deck of one of their little-used multi storey car parks, for solar and EVCPs.

We installed 5 dual Alfens, 87kW solar, and 3 Tesla Powerwalls at Wellgate Multistorey. That’s what we call thinking outside the concrete box..  or should that be on top of it?



Does installing a solar car port stack up?

When it comes to carports, they can be connected to a building supply or have their own independent connection and although both are technically feasible, are they a way to make under-utilised space productive from an economic point of view?

In short, it is still more cost effective to install solar PV on traditional roof spaces. The carport structure has to be built and there are associated civil engineering costs. The support structure is already in place on existing buildings, of course. However, not all roofs are suitable for solar, or a building may already have solar installed, and utilising car parking space can be a great way to boost additional onsite generation.

Also, solar carports are clear flagship projects – a way for solar and your green credentials to be very visible (which isn’t always the always the case on roof installs).

A growing market

In essence, solar carports can demonstrate a real link between renewables and electric mobility, and contribute to the achievement of sustainability goals. A wide range of design strategies are possible, and car ports can be an additional way of generating solar energy.

When it comes to this type of under-utilised space, we’re predicting a growth in solar carport popularity and an opportunity to shine in the right public sector and commercial spaces.

An iconic and award-winning install

Installing solar PV on Salisbury Cathedral was always iconic… and now it’s award-winning too!

We’ve just won the Alan Clark Award for Local/Community Energy at the Solar and Storage Live Awards, 2021 – and it’s an honour to receive it.

Community energy is something we’ve championed from the very beginning. It’s at the heart of who we are. We built the first community share-funded solar installation back in 2008, and the schemes are a fantastic way of getting renewable energy projects built at scale, within a local area, with local shareholders benefitting from the income generated.

Solar on Salisbury Cathedral

In the case of Salisbury Cathedral, a new group, Salisbury Community Energy, approached the Cathedral and we became involved via the Schools Energy Coop. We came up with a design that met the ecclesiastic planning committee’s stringent requirements and once approved, it was full steam ahead with the install.

You can read about the project in more detail here and as the Bishop of Salisbury put it,

“With clear purpose and helpful partnerships even iconic buildings can make a difference towards sustainability.”

Being recognised for our part in this historic project, alongside Salisbury Community Energy, certainly means a lot to us.


Let’s talk rising energy prices

Are you wondering why gas and electricity prices are rising and what the future holds? 

To discover more, we’ve been catching up with Professor Jonathan Stern, Distinguished Research Fellow at the Oxford Institute for Energy Studies. 

Jonathan is a specialist in natural gas issues worldwide, an author, an honorary professor at the Centre for Energy, Petroleum & Mineral Law & Policy, University of Dundee, and visiting professor at the Centre for Environmental Policy, Imperial College London. He is also a fellow of the Energy Delta Institute, a Distinguished Research Fellow of the Institute of Energy Economics, Japan, and a member of the EU–Russia Gas Advisory Council. 

In this interview we talk about what’s causing the current price rises, whether it’s a blip and what it means for renewables.
