The Solution
Simple Green Energy designed a comprehensive home upgrade package including solar panels, efficient heating, and loft insulation to maximise energy savings.
| Solar PV System | 1.74 kWp – 4 × LONGi 435W panels with Growatt inverter, mounted on south-east roof |
|---|---|
| Heating Upgrade | High-heat-retention electric storage heaters for steady daytime warmth using off-peak electricity |
| Loft Insulation | Mineral-fibre loft insulation top-up to modern recommended depth, reducing heat loss |
| Ventilation | Trickle vents and modern extract fan to control moisture and maintain air quality |
How it works together: The solar panels cover daytime electricity use, storage heaters charge on cheaper off-peak rates, and the loft insulation keeps heat in – so the system doesn't have to work as hard.
