What is the Smart Export Guarantee (SEG)?
The Smart Export Guarantee (SEG) requires licensed energy suppliers to offer a tariff to small-scale generators for electricity exported to the grid. Rates are typically 3-15p/kWh. You need a smart meter and an MCS-certified installation to be eligible.
Is my roof suitable for solar panels in Sandown?
Most roofs are suitable. You need at least 15-20 m² of unshaded roof space for a typical 4kWp system (10 panels). South, east, or west-facing roofs work well. Your installer will assess your roof's orientation, angle, and structural suitability during a site survey.
