Protecting homes from rising energy costs in Newham

Newham Council’s showpiece sustainable housing development goes solar

About the installation
Joju Solar won a competitive public tender to install a 20kWp system comprising 72 Sanyo/Panasonic 240W modules and 52 bespoke 45Wp brise soleil louvres on a brand new showpiece sustainable housing development for the London borough of Newham.

Installation time: 2 weeks

Challenge
To design and install an efficient solar PV system within complex architectural constraints and at the same time deliver strong financial returns. The PV installation needed to fit within a very tight program of works.

The new housing development was designed to lead the way in terms of both new sustainable home building and also to be a showcase in the borough for sustainable living. The solar installation was a key factor in allowing the client to meet the level five code for sustainable homes (a mandatory building requirement).

Solution
Joju Solar worked with the architect, principal contractor and other contractors involved in the development to meet the ambitious design limitations and tight program of works and delivered the project on time and on budget.
Our engineers designed a bespoke mounting system which allowed for the solar panels to be mounted above a green
living roof. The installation will deliver a high rate of return whilst at the same time helping the development achieve its sustainability targets.

What they said

Pip Watson, Principal Environmental Health Officer said “We wanted to lead the way in sustainable living locally. Joju delivered a bespoke installation which ticks the green box but will also reap strong financial returns for
the housing development.”

 

 

Julian and Lorena join the All Blacks

Julian and Lorena join the All Blacks with installation of 16 Solarworld’s 285w mono black solar panels

Background

When Julian and Lorena contacted Joju about a solar installation with home battery storage they wanted something that was going to complement their new home and fit in with its aesthetic. This is a pre-requisite of many of our residential consumers who voice concerns about how solar panels will look on their roofs and whether or not they will ‘fit in’. With existing solar tiles already out there on the market and Tesla recently annoucing their plans for solar tiles (see our installer’s guide to Tesla’s solar tiles) plenty of options are available. It is possible, however, to get the right look with panels. And that’s exactly what we did with the Solarworld mono black solar panels.

The Installation

16 Solarworld 285w  mono black panels were installed on Julian and Lorena’s new build property in Virginia Water, near Wentworth. There new build property is  supported by 4.56 kWp of All Black solar panels. The panels were mounted “in-roof” which means that they are flush with the roof line so blending in beautifully to the dark slate tiles and creating a brilliant aesthetic.  As well as the solar array Julian and Lorena also had a DC coupled 6.4kWh Tesla Powerwall installed, which stores excess solar energy for use in the evening.

The all black panels from Solarworld are German engineered. They come with the TUV Rheinland Power inspection mark and a linear performance warranty covering a period of 25 years, SolarWorld guarantees a maximum performance degression of 0.7% p.a only,

What Julian thinks

Julian says: ‘The solar PV and Powerwall system is the perfect addition to our new house. We are very pleased with the installation by Joju Solar and excited to have the sun help power our home day and night.’

Glenn gets Fully Charged

Glenn Tweedie’s decision to get a Tesla Powerwall and solar PV has led to both energy savings and TV fame!

Background

When Glenn Tweedie decided to have a solar PV array and a Tesla Powerwall installed on his family home in St Albans he probably hoped and expected that it would lead to energy savings for him and his family. What Glenn didn’t plan for was that the installation would lead to internet stardom and a starring role in Robert Llewelyn’s internet show Fully Charged. 

The episode of the show which featured Glenn and his family was filmed a few weeks after Joju installed the system, which included our first ever Tesla Powerwall installation in May 2016.

The Solution

In the Fully Charged episode Glenn talks to Robert Llewellyn about the benefits the Tesla Powerwall has brought to his family and just how much it has lowered their energy consumption from the grid. Indeed, on the day of filming 97% of Glenn’s Family’s energy had come from energy stored in the battery and produced by the solar PV. With only 3% being drawn from the grid thanks to both the 4.5kWp solar array and the Tesla Powerwall working in perfect harmony. Thanks to the SolarEdge PV monitoring platform Glenn and his family can monitor their energy usage via a smart app on their phones and laptops, which has enabled him to show his two sons just how much energy they are wasting when they forget to turn off lights and Playstations.

Getting Fully Charged

The video demonstrates perfectly the benefits of when a solar PV array is installed in sync with a home battery storage solution. The energy savings, the improved family education on energy usage, and even the status that come with having such a complete home energy solution are all highlighted and discussed in depth in the episode.

Marks and Spencer – Community Energy Scheme

Background

Historically, community energy initiatives have fallen into two categories, depending on where they draw their members from. Investors come from either the local area where the project is located or where the community is geographically scattered are made up of people with a shared passion. However, we’re proud to have helped M&S develop a new type of community energy scheme – where a corporate institution engages the community energy approach to finance renewable schemes.

Orchard Field Community School

Orchard Field School meets it high demand within strict grid restrictions

Orchard Field Community School is a large primary school in Banbury, Oxfordshire and a member of the Low Carbon Hub Solar Schools portfolio. The installation was installed in Summer 2015.

Challenge

Orchard Field Community School is a large primary school with a very high energy demand.  The school’s roof along with being large also curves around in a crescent moon shape. This presented a challenge in terms of how to secure the panels to the roof. The lengths of rail which we normally used on gable roofs couldn’t be used.  This also presented a challenge in terms of how best to wire the solar PV modules to the inverters, as panels facing in slightly different directions have different outputs depending on the location of the sun.  Orchard Field was therefore a tricky set up.

The final challenge was also to limit the potential export to the national grid. Despite the high demand on site solar PV export was limited to 50kWp, meaning that we needed to find a way to prevent the PV system from generating 50kWp more than the demand on site at any point in time – a very likely occurrence over the summer holidays.

Benefits

On a clear spring day the solar PV system meets the total energy demand on site. During the Summer this happens  more and more. Whatever the weather this system makes a significant reduction to the School’s electricity bills. And like all our installations in schools it has become a valuable educational tool for the pupils.

Why they chose Joju?

Joju have been one of the preferred suppliers of the Low Carbon Hub for several years and Orchard Croft is just another fantastic example of us working with them.

Headmistress Dawn Shilston said “As a school we feel incredibly proud to be doing our utmost to reduce our Carbon Footprint. It is incredible to consider we are the largest Solar Roof Project on a Primary School in Oxfordshire with our school roof hosting 384 solar panels. It has been an invaluable exercise in educating our pupils for the future on the importance for us all to explore the possibility of using renewable resources for our energy.”

Merton Council leads the way

Merton Council

London Council leads the way with green energy portfolio

Merton Borough Council have added over 200kWp solar PV to their impressive portfolio of solar in the last 3 months, creating 190,000kWh of free energy for local Schools every year.

Merton Council continue to demonstrate their green energy leadership by being the first council to install solar PV following the cuts to the FITs believing in the benefits that solar PV provide to the council despite the reductions in rates.

Challenges 

Merton had an impressive portfolio of solar PV before Joju started working for them. Sadly there previous installer had gone out of business and as a result left them with a number of sites which were not functioning correctly. They needed a new contractor to help them continue their program and fix any pre-existing system issues. This is where Joju were able to step in. Merton selected us to carry on the work because of our high ranking on the Fusion21 framework and based on personal recommendations.

The benefits

Each School has benefitted through reduced bills. At the same time the Schools’ have the capacity to access up-to-date data produced by the PV system, which is be used for educational purposes. The Council also see a long-term return on their investment through the new FIT.

What they said about us

“Joju Solar installed over 170 kWp of solar panels in under 2 months on challenging school sites across the London Borough of Merton. All stages of the process from planning to install were excellent and we have received high praise from the sites themselves about the way their teams worked on site.

Even in the current Feed in Tariff regime we can see the benefits of installing PV on sites and we are very pleased to have partnered with Joju for these installs and will be continuing to work with them in the future.”

Cabinet member for Environmental Sustainability and Regeneration, Councillor Andrew Judge said: “The installation of so many solar panels to our buildings around Merton is integral to the future of our community. I’m delighted as these solar panels will not only help save money and cut running costs by generating our own electricity, but will also allow the borough to become more environmentally friendly.”

Kate and Mike’s sound investment

Kate and Mike’s sound investment

Why did you choose solar?

“We had the capital to invest, and saw solar technology and the Feed-in-Tariff as a good way to make the money work for us.”

Challenge

Kate and Mike Jenns had spent much of their working lives as teachers and knowing that they would be spending more time at home during the day with their two chickens, two cats and a dog, Heidi, they wanted to take advantage of the electricity they generated. They also realised that without home renewables their electricity bills would be higher as they spent more time at home.

Solution

Going solar wasn’t a simple decision so before deciding to go ahead, Mike and Kate did their homework (no surprise for a pair of teachers) as they were concerned to make sure that the panels wouldn’t damage their roof and would provide a sound investment and in their first quarter they saw their electricity bill down by 40%

Simon’s solar installation

Simon Rowley’s conservation area installation 

Challenge

The overriding concern with this project was adhering to the planning regulations for a conservation area. Other essential roof repairs were also needed during the installation.

Solution

Joju Solar applied for and obtained a government grant on behalf of Simon. Joju Solar executed the installation project in conjunction with other essential roof repairs, demanding a high level of project management and coordination. Joju Solar ensured that the PV system, was installed flush with the existing roof, adhering to conservation guidelines for Ealing. This type of system is ideal for anyone re-roofing or undertaking new building work.

“I just thought I should record at this stage how pleased I am with the job that you did for me. Thank you!”

A great invesment for Chris

Chris Robbins best ever invest investment was solar

Why did you choose solar?

“I had been looking at getting a solar PV system fitted for a while to help reduce his electricity usage and to reduce my carbon footprint. After contacting Joju Solar a member of your Residential team came to visit my property to assess the suitability of my roof and to better understand my needs.”

Solution

After the site visit Chris decided to go ahead with a Sharp 245W PV panel installation. The final system design consisted of 10 Sharp 245W PV panels on a SB 2500 SMA inverter. The 2.45kW system will produce 2,060kWh per annum with a carbon saving of over 1.09 tonnes. Chris will be able to produce clean green electricity, future proof against rising energy costs and make savings on his electricity bills.

“Apart from the bees’ nest in the roof – which wasn’t Joju Solar’s fault everything was done very smoothly with little disruption. The panels are generating even more than was promised. This is probably the best investment I have made – much better than I was getting from the bank.”
