GSE In-Roof System: Enhancing Aesthetics and Performance

JLEC Electrical chose the GSE inlay system for this installation due to its superior aesthetics and performance. This innovative system integrates seamlessly with the roof, creating a sleek and visually appealing appearance. By eliminating traditional mounting systems, the GSE inlay system reduces the overall weight and wind resistance of the solar panels while ensuring excellent waterproofing.

G99 Application: JLEC Electrical's Expertise

The 6.32kWp solar PV system fell under the G99 application, which deals with the complex process of connecting renewable energy systems to the grid. JLEC Electrical, with their vast experience and expertise, efficiently handled the G99 application, ensuring compliance with all necessary regulations and grid connection requirements. Their professional approach and in-depth knowledge of the process were instrumental in seamlessly integrating the solar PV system with the residential property's electrical infrastructure.

Energy Storage: Empowering Energy Independence

Recognizing the importance of energy storage, JLEC Electrical installed a substantial 20.4kWh battery system alongside the solar PV array. This storage solution provides the homeowner with the ability to store excess solar energy generated during the day for use during periods of low solar production or high energy demand. By maximizing self-consumption and reducing reliance on the grid, the energy storage system enhances energy independence and promotes sustainability.

Intelligent Octopus Tariff: Leveraging Cost-Effective Charging

To optimize the cost-effectiveness of the battery system, JLEC Electrical programmed it to charge during periods of low electricity demand using Octopus Energy's "Intelligent Octopus" tariff. With this tariff, the homeowner benefits from a remarkably low rate of 7.5p/kWh (at the time of this post)

, allowing them to charge the battery at a reduced cost. This intelligent charging strategy maximizes savings and contributes to the overall financial viability of the system.

MyEnergi Eddi: Smart Energy Diversion

JLEC Electrical's commitment to innovative energy management led them

to install a MyEnergi Eddi device as part of the system. This device enables surplus energy generated by the solar PV system to be diverted and used to heat the property's hot water system. By utilizing excess solar energy in this way, the homeowner can further reduce their reliance on traditional energy sources and take advantage of the cheap nighttime tariff, resulting in substantial savings.


JLEC Electrical's installation of a 6.32kWp solar PV system on a large residential property in Leeds showcases their commitment to sustainable energy solutions and cutting-edge technology. Through the utilization of the GSE inlay system, expert handling of the G99 application, integration of an energy storage system, intelligent tariff optimization, and smart energy diversion, JLEC Electrical has created an energy-efficient and cost-effective solution for the homeowner. This project stands as a testament to the possibilities of solar power and serves as an inspiration for others seeking to embrace renewable energy and reduce their environmental footprint.
