How can I calculate my total electrical demand?
Your total electrical demand (or ‘load’) can be calculated by your installer. You will need to provide them with information such as the quantity of lights, house appliances etc. If you wish to run off the solar system, you will need to state your average daily use which is listed in many electricity bills. The installer will then be able to calculate the consumption/kilowatt hours per day, or ampere hours per day, that the system will need to provide to generate complete supply.
