The Project
Mr and Mrs Latter were keen to utilise solar for their family home in Troon to reduce their electricity bill and provide long-term savings.
Having limited roof space, some shading, rosemary tiles and different roof orientations were some of the main challenges we needed to address in order to design the perfect solar PV system for their home.
Sunpower panels were selected due to their superior performance, warranty and durability (especially in salt-mist environments in coastal areas) and maximising power for the area of roof space.
SolarEdge power optimisers were selected to minimise the impact of shading and to deal with the different roof orientations.
Schletter with Hookstop tiles (http://www.redtip.co/hookstop) were used
to mount the system and protect the rosemary tiles.
The Result
A fantastic, high performance solar PV system which is outperforming the SAP calculations by nearly 20% every year.
Customer Quote:
“First class fitting and service – I had a solar pv system fitted and it’s been installed now for over a year and never once have I had a problem with it or has the system not worked. The production of the system is far higher than the SAP values and has proven to be a very good system at the price it was installed at.”

The Project
Situated in the beautiful highland surroundings of Spean Bridge, this eco-house is served by a 9.81kWp Sunpower PV system, two SolarEdge inverters and a Tesla Powerwall integrated so that the house will be able to benefit from solar PV power at night. The house is heated by a ground-source NIBE heat pump (not installed by Ceiba).
Dr Giles, the customer, wanted his new home to be as self-sufficient as possible. With a SAP energy calculation of 7,022kWh for heating, hot water, ventilation and lighting the aim was to be net carbon-neutral – i.e. the solar PV system should generate more electricity per annum than the house consumes.
As a new build project, the initial design had been for an in-roof system over multiple roofs. However, after consultations with Dr Giles we agreed that due to the sliding roof and other factors that a ground-mount option would be better suited to this project – Ground-mount systems have the advantage of being able to be oriented to south and aren’t as restricted as a roof for space so we could increase the size of the system.
To enable use of some excess solar power at night we specified the 6.4kWh Powerwall from Tesla.
The Result – 2017 so far
The results so far have been very good. Visually the solar PV system looks great, seamlessly built into the hill at the front of the house.
Data for 2017 shows that self-consumption is sitting at 64% having generated 2,485kWh from 1st Jan 2017 to 6th May 2017. That means that 1,580kWh have been used in the house, while 895kWh have been exported.
The house electricity consumption has been 4,900kWh, with self-consumption of solar power standing at 32% (1,580kWh) and we’ll expect that percentage to increase in the coming summer months.
Since installation in June 2016, the solar PV system has saved 4.2 tonnes of CO2 and having used Sunpower panels with their Cradle2Cradle certification, the solar PV system itself is already carbon negative.
Overall, the solar PV system is making a significant contribution to the energy requirements of the house. With this data we’re building up a valuable picture and it’s clear that there is scope for more battery storage in the future to further enhance self-consumption and savings.
Customer Quote
“Simply the best! Ceiba Renewables worked with us to design the PV system for our new build house in the highlands. They provided a more comprehensive service than any other company we contacted about the project, from estimating its size, through design and specification to installation. This included implementation of new technology such as the Tesla Powerwall. They tackled a whole series of issues and no problem seemed too difficult. We used many contractors on our new build but in terms of knowledge, professionalism and service Ceiba Renewables were in a class of their own.”

The Project
Mr and Mrs Baguley engaged Ceiba Renewables to look at a suitable solar PV system for their family home in Aberdeenshire. They wanted a solar PV system that would help to protect them from rising energy bills and, importantly, one that wasn’t going to deteriorate over time.
A key consideration in the design of the system was to maximise yields and minimise the impact of winter shade from neighbouring buildings.
After exploring and assessing the costs and benefits of various options, it was decided to maximise the roof space and look at how much it would cost for a grid connection for a 9.16kWp system on their single-phase supply. Ceiba undertook the required design and application work to SSE free of charge. With SSE coming back with a favourable quote and within the customer’s budget, they decided to place an order for Sunpower’s amazing E20 high performance solar panels combined with SolarEdge’s power optimiser system that allows each panel to operate individually and to its maximum potential.
The Result
In its first year the Sunpower with SolarEdge PV system has outperformed the estimated annual production. As can be seen from the table below, from the 1st May 2014 to 1st May 2016, the PV system produced 17,249kWh, exceeding its SAP calculations by more than 15%.
From SolarEdge’s free monitoring system we can see how the system performs over time, compare year on year trends and look at individual panel performance.
With a 10-year workmanship warranty, 25 year power & product warranty on the panels and SolarEdge 12 year inverter warranty, the system is well protected to keep producing excellent results for years to come.

The Challenge
The park was consuming around 101,000kWh of electricity per annum and the owners were looking at ways in which they could reduce this consumption. Solar PV had been considered for some time but problems had arisen in finding an installer that would provide a quality service and product at the right price. The intended site also had a boiler chimney stack that shaded part of the roof.
The Project
Deeside was introduced to Ceiba Renewables Ltd in October 2013. Having spoken at length with Deeside about their requirements, the team were acutely aware of the importance of installing a quality product that would yield an excellent performance over the longest possible period, and would provide peace of mind from both investment and safety aspects. Drawing on the teams capabilities from their vast experience in solar and electrical design & installation, a solution was proposed that met Deeside’s requirements.
The Design
The shading aspect across different panels at different times of day was a potential problem, and the yield of a conventional installation would have been affected by this issue. Any shadows on a single module would normally reduce the performance of the whole array as all the modules are connected. However, micro-inverters linked to individual panels negate this problem. This system increases energy production, simplifies design and installation, whilst improving system uptime and reliability. With an all AC approach it also has the benefit of reducing fire safety risk.
The Result
We received great feedback from the customer following the installation which is always satisfying to hear as we take great care to provide an excellent experience for our customers. The system has been installed for over 3 years with no faults or issues.
Customer Quote
“Having looked for years for a suitable supplier/contractor, we found an outfit we could trust. The quote was tweaked, and I was happy we had the system that would work for us, and that we had back-up if things went amiss.
Installation was trouble free and professional, and the electrical control board is a work of art.
We have 95 panels, and my only regret is that we don’t have a big enough roof to install more. I am also confident that Ceiba Renewables will be there if need be. I would not hesitate to recommend this winning team!”
