24/7 solar in the London Borough of Camden (CP745)

LEAD AGENCY: London Borough of Camden
OTHER PARTNERS: Lakehouse Contracts Ltd, London Borough of Waltham Forest, Solgain UK Ltd.
PROJECT SUMMARY: The project will install and compare the performance of three makes of batteries from, Moixa, Sonnen and Growatt in 41 properties across three London boroughs. The systems are manufactured with differing battery technology and product costs. The evaluation will consider the cost effectiveness of the different systems. Camden Council will administer the scheme to fit the batteries into 41 council owned and tenanted street properties in Camden, Islington and Waltham Forest. The project is being delivered by the London Borough of Camden, with partners North Star Solar financing the solar PV and sourcing the best battery models available on the UK market, Lakehouse overseeing the project and construction, and Solgain carrying out the installations. The three local authority partners are providing enabling works, project management and home energy advice visits. The project aims to significantly reduce household electricity bills and will this will be monitored and verified through robust evaluation.
EVALUATION METHODOLOGY: Conduct household interviews with a sample of each sub-group to capture household behaviours and previous energy expenditure.

Supplement household interviews with energy and thermal data logging conducted with recognised calibrated standalone devices, smart metering, manual energy readings from householder, and “cloud connect” portal capturing and storing energy flows between PV, Battery, and Household use by time.

PROJECT OUTCOMES:
  • NEA is interested in the benefits to the fuel poor of storing electricity generated by PV during daylight hours and supplementing the householders’ evening use with this stored energy. Many fuel poor householders do not own the PV arrays on their homes and don’t benefit from Feed-In or Export tariff, and are out of the property during the day, with limited opportunity to utilise the free electricity generated.
  • The programme will improve current understanding as to the role ‘Battery Storage’ can play in reducing domestic electricity costs.
  • Findings will indicate to what extent householders will adapt their behaviour to utilise stored electricity during the peak 4pm to 8pm period.
  • Research in this area to date has focused on affluent households; NEA will add low income households to the current evidence base.
  • Comparative data will be generated to assess the performance of each brand of battery storage set against key parameters such as installation, reliability and savings generated.

Extended TIF programme, results due summer 2018
Monitoring and evaluation of this programme will continue during the winter of 2017/2018, doing so will enhance the quality of data and enable a comprehensive evaluation to take place.
