The electric car market is on the rise. For example, the past year saw a sharp growth in the number of registered pure electric cars in Flanders. A survey by iVOX showed that 7 out of 10 Belgians feels ready for an electric vehicle.
iLumen also notes the increased interest in electric cars. For example, customers find it increasingly important to consider the presence of an electric car, which is already in their possession or which they will purchase in the near future, when dimensioning their solar panel installation.
Based on measurements from practice, you can count on the average driver consuming about 25 kWh of electricity per 100 km. Someone who travels 40,000 km on an annual basis, in other words, needs around 10,000 kWh of electricity. Logically, the electric consumption of a driver with a sporty driving style, analogous to petrol and diesel cars, is higher than with a quiet driver who seldom drives on the motorway.
In practice, we find that on average about 50% of the number of charging cycles of electric cars takes place on site (eg at work) and the remaining 50% at home. For someone who travels around 40,000 km a year, this amounts to an extra household consumption of around 5,000 kWh.
With this data, your PV installer can perfectly calculate how many solar modules a specific customer needs to cover his household energy consumption and the consumption for charging his electric vehicle.
Electric vehicle as a battery
Currently, much research is being done on the possibility of using electric cars as a battery in the future. In the evening, when your solar modules do not generate energy, you could use your car as a household energy battery. During the day, the surplus of solar energy can then be used to recharge the battery of your electric car.
