Funding growth in a competitive sector

Windowflowers Ltd, based at its nursery in Burnham, Buckinghamshire, is the leading independent supplier of floral and horticultural services to the commercial sector in the UK, renowned for exceptional service and artistic floral arrangements.

Electricity was a fixed and rising overhead. The business needed a cost-effective, sustainable solution that would reduce bills and release capital to reinvest in customer service and product range.

A 32.8 kWp, 80-panel rooftop array

Solar4Good installed a 32.8 kWp system using 80 Canadian Solar 410W panels with a Solis-25K three-phase inverter and 80 Tigo optimisers, sized to the company's daytime demand so most generation is used on site.

At a £31,542 system cost against £5,280 saved each year, the array is set to pay for itself in about six years — then keep saving for two decades beyond.
