Summer is always incredibly busy for us and our clients continue to recommend us to friends, family and neighbours..
we’ve just completed another top spec installation locally incorporating 20xSOLARWATT glass glass modules, a Fronius UK GEN24 plus 8kw inverter and Fronius Reserva Pro battery modules providing 20kWh storage ⚡️
This one will certainly reduce the clients energy costs with an estimated generation of 7328kWh annually 👌🏻

We’ve just completed another installation locally with a fully European system for our client.
The Fronius UK GEN24 Plus and Reserva Pro modules are incredibly popular with clients wanting a superior performing system, made in Europe and installed by the longest standing accredited Solar PV company in West Yorkshire having held MCS accreditation for 16 years👌🏻⚡️

We recently installed this 5.58kWp system for a client.
Since commissioning, in just a few weeks the system has already generated 1469kWh⚡️

The Fronius system comprises of a GEN24 hybrid inverter, Fronius Reserva battery storage and a Fronius Wattpilot EV charger.
The client is making use of excess generation by charging his Electric Vehicle from the sun.
The whole system is powered by Solarwatt glass glass modules.

When we were called in to help a couple who had had a system installed in 2019 by a supposed MCS accredited company to find they had no certification issued, no connection approval and a system that was a complete mis match with some componants not working, there was only one solution and that was to take it out and start again.
These clients are passionate about the environment, already have an electric vehicle and were wanting to be less reliant on grid power.
We decided to retain the Solar panels as that was one aspect that was in good order and made no sense to replace and we applied to the DNO for a connection agreement. We have removed and will recycle all the other equipment.
We then installed a quality Fronius UK
system external to the property including a 6.0kw GEN24 hybrid inverter and 12kWh of battery storage with the Fronius Reserva Pro fully European modules. ⚡️

Another installation completed by the team comprising;
SOLARWATT glass glass modules
Fronius UK GEN24 hybrid inverter
Fronius Reserva battery modules and a Fronius Wattpilot Flex EV charger
Our client benefits from high spec products, with a system that integrates perfectly allowing him to harness energy and charge his vehicle from the sun ☀️
The client has already generated 2665 kWh in the Spring months alone and we expect this one to do incredibly well over the coming year.

Customers sometimes say our quotation is higher than others they’ve had.. more often than not, the competition hasn’t been to site, hasn’t looked at the roof, taken measurements and designed a system to accommodate multiple elevations whilst providing the best possible solution for the homeowner.

*We survey every installation
*We design per property based on numerous factors- if you want a quick Google quote, we’re probably not the company for you.
*We don’t subcontract any of the installation.
*We install to a high standard and to the quoted specification
*We provide after installation support to all our clients

We are proud of our 16 years installing Solar PV💪🏻

Last week we installed another system for a client who opted for the fully European Fronius UK GEN24 hybrid inverter and Reserva Pro battery modules.
The client now has 11.94kWh storage with a neat installation to compliment his existing Solar PV array.
If you’re considering Solar PV or battery storage and want a high quality, high performing system, get in touch and we’ll be happy to arrange a survey.

This one took a while to get over the line with planning constraints, but we got there. 💪🏻
Initially setting the clients Fronius UK GEN24 plus and BYD BatteryBox up as an AC coupled system, we were able to return after a year to install the SOLARWATT UK & Ireland modules on this ground mount array.
In its first month alone in April it generated 922kWh 🙌🏻
We can’t wait to come an eye on this one and see it surpass our expectation annually.🤩
Another stunning installation in the heart of Yorkshire and proof that despite lots of hurdles, you may eventually be granted the system you want to reduce your carbon footprint 🌱 Fronius UK SOLARWATT
