Nice little Sigenergy Sigenstore system installed last week by the team this 7.84kW array, is expected to generate 6505kWh per year and when paired with 2x6kWh batteries is predicted to reduces the amount of electricity this customer is takes from the grid by 83% and coupled with export payments another bill that is has been turned on its head and likely to become a small income.

Not all projects need to be huge, or require the use of premium brands such as Tesla or Sigenergy.

In fact one of our most popular offerings is FoxESS. A perfect mid-range inverter & battery combination when balance of cost, performance & reliability all need to be taken into account.
Regardless of the product we still take the same great care and attention when installing your chosen solution such as this recent installation, a FoxESS 6.0kW hybrid inverter coupled with 10.36kWh of useable battery storage via an EP12 battery.
Still matched with 14No. Premium Aiko 490w All Black Gen3 Solar PV panels & bird prevention mesh.
This system and size is the perfect all rounder for majority of ‘average’ households and may well come in better value than many expect.

For this customer this system, is expected to generate just under 5800kWh per year, reduce their grid dependency by 90% and turn their electricity bill into an income stream!

As another warm week draws to a close the team have out done themselves again with 3 jobs completed.
But first a few pictures from last weeks tricky job, with 4 slate roofs on 2 detached buildings this 26x465w Aiko panel system is optimised due those tricky shading arrangements and multiple pitches. This system packs a punch! We’ve already witnessed this system deliver in excess of 70kWh in a day!
Paired with with Sigenergy Sigenstore system include 12kWh of battery
Expertly installed with care by our In-house team of skilled craftsmen and designed to last its lifetime. You won’t find a cable on show or slate out of place.

Fantastic effort by the team couple of weeks ago in the ferocious to get this one complete - 27kWh of battery storage via Tesla PW3 & expansion pack, off grid gateway, Gen 3 wallpod EV Charger powered by 16 Aiko 490W Neostar 3S panels, to the South and even a further 11 to the North all finished with bird prevention mesh and expertly installed with barely a cable in sight. This all out system packs a mighty punch and fit for the future with another very happy customer.
A special note regarding this project: This customer has a procurement background and did a lot of his own research, went out with a very specific brief and requested quotes from over 10 companies and to be selected not based purely on price but on the knowledge, quality of installation we deliver, customer care both before & after installation.
We build solar solutions to last for its lifetime not just its warranty period.

Another week another Tesla Powerwall 3 system expertly installed by the team. These are proving very popular at the moment and although a premium product it still represents great return on investment and with an 11.04 kW discharge also one of the most powerful and when coupled with a gateway for wholesome back-up such as this installation they are second to none.
Paired with 17No. All black 470w Neostar 3S Aiko panels it is projected that this customer will turn their energy bill into an investment, not only saving them money but it should actually turn a profit each year with the right energy tariff.
Last week of Tesla’s upto £750 reward card promotion - Registration ends June 30th so get in touch now if you think this is for you and take advantage.

Well, single phase residential solar PV & battery installations don’t get much bigger than this. So proud of the team for battling through the mixed weather of last week to create this masterpiece and ensure the aesthetics are just as good as the performance. This huge 16.4kWp array is made up of 36No. 465W All black panels across 4 different tricky roofs is expected to produce just shy of 12,000kWh of clean energy per year. Paired with 27kWh of battery storage via 2No. Tesla PW3’s a Tesla Gateway for Off-grid use and a Tesla Gen3 Wall Connector. This really is a monster system with all the bells whistles. And guess what you won’t find a surface mounted external cable in site!

If you want honest advice on whether a solar battery system is right for you and an installation built to last for its lifetime not just it’s warranty by a team of skilled & dedicated engineers who treat your property as if it were our own then please get in touch!

Have you got FIT? No we don’t just mean for summer we mean existing Solar Panels fitted prior to 2019 where you are likely to be receiving an income for purely generating your own electricity and likely obtaining 50% deemed export. Then it may be time to get that system working even harder for you just like this customer who will continue to receive all their FIT payments but harvest the full amount of energy via this battery system. And what makes this system even better is the system has an EV so during the duller days this customer can top up their battery up overnight using energy at 8.5p per kWh. And for the eagle eyed amongst yes the existing Immersun energy diverter is still connected and in use without competing with the battery ensuring every drop of generated energy is utilised by the home.
Plus a backup gateway for full home power cut protection.

Premium products deserve premium installation.
Proud of the team for getting this tricky job to look so good. Even more-so when most of it’s in the back of a kitchen cupboard!
Not all property’s lend themselves perfectly to large Solar arrays, but even so the benefits & savings of utilising off-peak energy slots to charge up and use during peak hours can be huge particularly when running heat pumps and other such devices. This property is fitted out with a 2.94kW array consisting of 6x 490W Aiko Solar panels, 27kWh of Battery storage via Tesla PW3 & DC Expansion pack in addition to a Tesla Gen3 Wall Connector and Whole home back-up protection via a Gateway!

Have you benefitted from free Heat pump & Solar PV installation via an ECO4 grant like this customer only to find that you export all that free generated energy during the summer, and there’s not enough to run that heatpump in the winter?
This customer got us in to do something about it. By replacing the existing 5kw inverter with this Hanchu 10kw inverter and installation of 37.6kWh of batteries via 4No. 9.4kWH Hanchu LV batteries this system now allows the existing 8.8kw Solar panel system to really generate to its maximum output during the summer and make most of cheap off peak overnight electricity during the winter months by charging up these batteries at the same time as there EV.
Although not our favourite system to install this brand represents fantastic value per kWh and is great for the budget conscious clients with large energy demands.

Finished photos of last weeks installation in Mold this 14x475W Aiko solar panels complete with bird prevention mesh installation coupled with a 6kW FoxESS inverter & 11.52kW EP12 battery is expected to generate 4,627kWh per year and reduce this customers grid dependency by 83% and with the additional payments from the surplus energy generated & exported it is highly likely that their electricity supplier will be paying them every year!
