Residential – Hybrid Inverter with Batteries

Case Study

A more recent example of a Solaflex installation was on a high spec garage in Martinborough. From the outset the customer knew he wanted Solaflex and this was part of the design brief given to the architect. The advantage of considering the Solar element early in the design phase is that the roof was designed to be almost exactly the length required to accommodate a strip, and the roof pitch and orientation of the structure was also optimised. Being that the energy generated from this roof would also service the existing main house on the site, we were instructed to maximise the roof space on the garage.

Furthermore, the owner opted to include a battery facility into the design so he would have an emergency power supply in Grid outages common to the area, and so that excess energy could be captured and stored for evening use – this is the best way to maximise the value of the generated energy and to get the best return on investment and therefore shorten the payback period of the system.

In this case we opted for a GoodWe ET Hybrid HV 10.0kW 3 Phase Inverter, and a BYD HVM lithium ion battery facility consisting of 5 x 2.76kWh modules (. The advantage of the BYD modular system is that it is expandable so that you can start with a small number of o battery modules and expand over time in the future as required.

The garage was phase one of redevelopment of the site – the main house in intended to be constructed as a secondary stage but the owner has already decided to specify Solaflex for the main house also.
