Eco-Exmoor Devon encourages the use of renewable energy, but saving energy is of primary importance. Saving energy reduces you fuel bills, lowers your carbon footprint and combats climate change.
Here are some of our tips for saving energy. Some involve no cost, just a change in behaviour. Others involve investment
, but pay for themselves over time.

You have installed PV and now you wish to reduce your reliance on the grid even more to:
How do you do it? There are a number of ways this can be achieved:
PV is generated when the sun is out! Obvious!!
Firstly you need to learn about and understand the electricity demands of your appliances. All appliances are power rated in watts (W). The higher the watts, the higher the electricity demand. All electrical appliances sold within the EU must have a label showing basic information:
This label from the Eco-Exmoor Devon office kettle shows that it is rated at between 1850 to 2200W. Look at the rating of your appliances to assess the maximum power demand. Typically,kettles, washing machines, dishwashers, and tumble dryers are energy hungry. Note that their demand is uneven during their operating cycle. A tumble drier is a constant high demand, but a washing machine peaks when it is heating the water during its wash cycle. Our office kettle would consume over 50% of the electricity generated by a typical domestic 3.6kW PV system during the midday peak generation period, but is only on for about 3 minutes. So make your coffee before drying your clothes, otherwise you will demanding more than your PV system can generate.
The best way to maximise the use of your energy generation is to operate you energy hungry appliances during the daylight hours when you PV is at its peak output. Do not operate them at the same time though! Plan to stagger their use; run the dishwasher after your washing machine. Also remember that peak PV electricity generation occurs between the hours of 12:00 and 15:00.
The scope for maximising self-generated electricity usage can limited by a number of factors:
To improve your utilisation further, you need to consider PV Smart Technology solutions next.
