How A Buzzii Solar & Battery System Can Deliver Value

Lower Your Electricity Bills

Generate your own renewable electricity and store excess energy for later use, helping to reduce reliance on the grid and lower household energy costs. Lower energy bills: Households can cut bills by 55%-75% depending on system size and usage. BBC

Smart Export Guarantee Payments

Receive payments for electricity that you don't use. Any surplus solar energy you generate can be exported back to the grid through the Smart Export Guarantee (SEG), creating an additional benefit from your solar and battery storage system.

Additional Grid Support Earnings

Only Buzzii systems can participate in grid-support services, providing an additional guaranteed annual payment over and above the SEG, through our exclusive energy management platform. No other UK solar installer can currently provide this offer.
