Use of storage and renewable electricity generation to reduce domestic and transport carbon emissions

Investigating the whole life energy, carbon and cost of an integrated renewable energy generation system.

Whole life energy and cost analysis of single dwelling case study (UK)

The case study is a detached dwelling situated in South Wales, UK.  It had 3.6 kWp vertical solar panels (PV) installed in 2014 and a 6.12 kWp roof mounted PV installed in 2020 along with a 13.5 kWh electricity storage device, closely followed by an electric vehicle and charger.

The impact of these interventions on reduction of domestic and transport carbon emissions is considered in relation to energy tariffs which encourage the user to shift consumption from 'high carbon' generation times (generally matching peak consumption in the evening) to 'low carbon' generation times (generally overnight or during peak renewable energy generation).

First year monitored data is used to assess the validity of the pre-installation cost-benefit analysis which was used as a basis for carrying out the investment. It is also used to consider the whole life payback of the embodied energy and carbon.
