Welcome to geo’s Chorus PV, our advanced

energy management service for homes

withPV(solar)arrays.

The Chorus allows you to take control of

your energy by monitoring home use and

solar generaon at the same me. The

Choruslearnsyournormalusagepaerns

for each day of the week, so the display

can tell you when to use electricity at the

most ecient mes – meaning you can

reduceyourbillsandsavemoney.

Knowing your energy paerns will help

you set realisc budgets appropriate to

you, your home and the me of day or

year. The Chorus provides at-a-glance

informaon on whether you are above

or below your budget so you can keep

track 24/7. Simple graphics show usage,

cost and carbon. You can check just how

environmentally friendly you are being

(the more environmentally friendly, the

greaterthesavings).

With geo’s web pack, you can access all

this data from your Chorus display or

online on our energynote website. Here

you can set up your own personalised

account with more in-depth informaon,

look at your energy use in as much detail

asyouwouldliketosee.

 When ng the sensors, if the

Feed-in tari (FiT) / Generaon tari

When you generate your own electricity

your energy supplier will pay you via a

feed-intari(FiT).Theamountissetbythe

Department of Energy and Climate Change

(DECC)andiscurrently16p*perkWh.

Rates change depending on the size of

your system (those few of you with a

system of over 4kWp are paid slightly less)

and the rate of take-up (also called the

Deeming / Export tari

Now your solar panels are up and running

you will, at some stage, generate more

electricity than you need to use. This is

most likely to be when the sun is shining

and you’re out for the day. So as well as

your FiT/generaon tari you can sell

extra units back to your supplier on an

exporttari.

Because it’s not possible for your energy

supplier to measure exactly what you

are exporng, the energy suppliers use

deeming. This is a scheme whereby the

energy supplier assumes that you export

50% of what you generate.So if you are

paid4.5pperkWh,youwouldworkout:

kWh generated x 4.5p x 50%.

Calculate your savings

Using the electricity you generate as

gridsavesyoumoney,obviously.Buthow

much?Andwhen?Weshowyoujusthow

much you’re saving on the income app;

Scrolldownunderneaththecalendar.

Chorus PV display 13

The amount of money saved depends on

your tari. For example, if you use 4kWh

of generated electricity and you pay 16p/

kWh for your electricity from the grid then

it would work as follows:

kWh of generated electricity used x cost

of grid electricity = 4 x 16 = 64p

It’s simple: the more you use your own

generated electricity, the less you’ll import

fromthegridandthemoreyou’llsave.If

you navigate further down into the income

appyoucanviewsavingsbymeperiod.

Cost

Any electricity you import from the grid

you will be charged for. By using the

electricity you generate as eciently as

possible, you can aim to keep any import

downtoaminimum.

To help keep any eye on your costs

the Chorus gives you a way to set an

appropriate monthly budget. This budget

is updated during the day to show you

Theswingometerprovidesanindicaonof Environment

Using the electricity you generate doesn’t

just save you money, but also helps the

environment. That’s mainly because the

energy you generate at home is carbon

neutral (i.e. no power staon). The

environment app shows what percentage

of the electricity you generate you have

used in your own home at that point in the

dayandhowmuchcarbonyouhavesaved.

The higher the percentage, the more of

your own electricity you’ve used and the

kinderyouarebeingtotheenvironment.
