A1:  An average family household might fit 13 solar panels which generate about 3,600 kWh per year.  The panels and installation would cost around £5,250                        including warranties on equipment and the overall installation.
We would hope to reduce this with our community procurement scheme.

A2: Yes.  A Solar iBoost to use your surplus energy to heat your hot water tank will cost around £450.  It will save around £40 per year, depending on usage of hot water.
A battery allows you to store electricity in the day to use at night or on cloudy days but cost almost £3,000.

A3:  A medium household will use around 3,400 kWh per year costing about £540. The daily standing charge will add another £75 to this.

A4:  This is often abbreviated to SEG.  It pays households for the excess electricity they generate but don’t use themselves.  It came into force on 1st January 2020.  It           replaces but is not as generous as the old Feed in Tariff.
        You have to sign up to a SEG tariff with a electricity supplier it doesn’t have to be your own supplier.  The amount they pay you varies between companies; some         only 0.5p /kWh and others, like Octopus, 5.5p /kWh.
       You are likely to need a smart meter which sends readings to your supplier every half hour.  There is no cost for a smart meter installation.
       If you get 5.5p /kWh your annual export earnings might be in the region of £90 per year.

A5:  This depends on several factors such as whether you are at home during the day to use the energy you generate. And they are calculated using an average of standard tariffs.  So these figures are a guide only.
Possible Savings per year:-

Electricity bill                            £270
Gas bill*                                      £38
Smart Export Guarantee        £90

TOTAL                                        £398
*This would only apply if your installation included an iBoost which heats your hot water tank

A6:  Most estate agents say they make no difference
