This West Sussex install is a fully optimised system with battery storage and immersion control.

This system uses the BISOL 300W European modules fully optimised with Tigo individual module optimisation. In addition to ensuring each module is generating its maximum power, the Tigo units also allow our customer to see what each individual panel is producing in real time.
The panels are connected to a SolaX Hybrid inverter which controls the solar and the battery. To reach the maximum self-consumption achievable immersion control for hot water heating was provided using a PowerFlow E.R.S. Mini, this diverts surplus energy generated to heat hot water in an immersion tank. Any more excess energy after this is then stored in a SolaX battery with a capacity of 6.5kWh.


I found the company from Checkatrade and have been very pleased with their quality of workmanship and support throughout the installation and post installation when a minor fault was detected, Mark Wells made sure he visited within a few hours to check and solve the issue. Overall, I would recommend the company.
