Solar panels getting bigger and cheaper
Savings and income increase from £540 to £635 per year
New data from the Energy Saving Trust has revealed that the average combined savings and income made from households installing solar PV panels has increased by nearly £100.
Previous data prior to 1st November this year indicated that the average combined savings and income for households installing solar PV panels was around £540 per year; however, new figures show this has increased to £635.
Energy Saving Trust, who assessed the data, indicate that the main reason for this increase in income and savings is due to the average size of the solar PV installations increasing, even though the Feed-in Tariff rate has dropped.
Ian Cuthbert, renewables expert from the Energy Saving Trust, says, “The average size of solar PV installations has increased from 3kWp to 3.5kWP, which basically means households are generating more electricity and therefore more savings and Feed-in Tariff income. It is clear that UK households are increasingly looking to get the maximum yield for their roof to maximise the benefits of the solar installation.”
The updated solar figures have been published alongside new survey findings from the Energy Saving Trust which shows a third of people in the UK have been approached with solar panels in the past year but only four per cent chose to purchase them.
Ian Cuthbert says, “We hope the latest data and figures will provide householders, whose homes are appropriate for solar panels, with the reassurance that they will be making significant savings and income as a result of the installation.  These savings could be even higher if householders take steps to reduce the amount they export to the grid by shifting some of their electrical demand to during the day when the solar PV system is generating. For example, using the washing machine during the day instead of at night.
