Grid Benefits of Vertical Solar

VBPV's dual morning and evening generation peaks align 18% better with UK electricity demand than conventional midday-only solar — reducing battery storage requirements, grid reinforcement costs, and the duck curve problem that is already straining UK grid infrastructure.

Important correction: Earlier campaign materials cited total system savings of £161–187bn, based on pre-2025 BESS cost assumptions of £250–300/kWh. This figure has been corrected. Using verified 2025 benchmarks (BloombergNEF $117/kWh; Ember $125/kWh), revised total system savings are £25–35bn. The grid benefit case remains compelling and is now grounded in auditable current data. See full methodology →
