250 systems : 0.5MWhWe have developed a network of installers and also partnered with AVC-NextGen during the project for large multi-site installations – who previously installed satellite TV systems across the UK. This has helped to define storage and DC (Direct Current) installation processes, optimise install to typically 1-2 hours enabling multi installs per van team/day. This has also improved survey and co-installation approaches for DC Lighting and new solar.

Distributed Storage Summary
UK market opportunity post FIT New opportunities despite major challenge of sudden FIT shock
Clarity: No subsidy (GD/FIT/RHI/RO) - > level playing fieldStorage insights: Systems as solutions.
Right timed – incorporating energy storage to store and shift power to peak times and balance system over day
Right placed – targeting smaller properties, urban previously too small for larger subsidy driven arrays
Right Sized – smaller arrays to maximize self-consumption and reduce peak solar network challenges and charges
