Terminology and Technology
Our houses are big emitters of greenhouse gases (mainly carbon dioxide). Our homes account for 26% of total UK emissions. The average home currently produces 8.1 tonnes of CO2 annually. The UK Government wants to reduce that to 4.5 tonnes by 2030.
So how do we do that?
The first question is to ask how much electricity do you use?
First up, a kilowatt hour (kWh). This is the way electrical energy is measured. Kilogrammes (Kgs) measure weight, energy suppliers use kilowatt hours (kWh) to measure how much energy you have used and then work out your bill.
As a rough guide, 1 kWh gives you enough energy to boil a kettle 10 times or watch 7 hours of TV.
Secondly it is very difficult to talk about “the average household”. The amount of energy you consume will depend upon the number of people in the household, how much of the day they spend at home and the number of appliances they use.
Capacity of the battery.
Battery capacity is how much electricity the battery can store in kWh. Useable capacity is less than total capacity because batteries should not be discharged completely as it damages them. Signal Solar Energy offers many sizes of domestic, commercial, and portable batteries. [link to Products page].
Signal Solar Energy’s domestic batteries have a charge time of 6 hours which means that you can easily fully charge the battery overnight using off-peak power or during the day if you connect your battery to your solar panel array.
Number of cycles.
One ‘cycle’ is a full charge and full discharge. Our Domestic Batteries have 10,000 warranted cycles This means that the 10kW battery will give roughly 100,000 kWh over the lifetime of the battery.
