If you’re looking to maximise the value of the surplus energy generated by your PV system, diverting this to EV charging makes sense from both an economic and environmental perspective.
Electric cars are coming of age.
There are 130,000 electric vehicles driving on UK roads, car manufacturers are investing heavily in the technology, and the charging infrastructure is gradually being rolled out.
What's more electric vehicles are already breaking all of the records. Whilst the gas guzzling Bugatti Chiron manages 0-60 in a leisurely 2.3 seconds, Japanese car maker Aspark has produced the electric Aspark Owl which does 0-60 in 1.921 seconds. Meanwhile the electric Range Rover Sport has recently climbed the ‘999 steps to heaven’ in Tianmen Mountain (watch the video from the start of minute 4 if you don't want to listen to the preamble). And of course, Elon Musk's Tesla is nearly 5 million miles away from Earth, travelling, at the time of writing, at a speed of 7257 miles / hour, doubtless with Bowie's Starman still blaring out to announce man's latest visitation in space. Along with a load of our very best bacteria, apparently.
All very exciting. Back to the mainstream...
Driving an electric car costs around 3.5p per mile as opposed to 15p or more per mile for a petrol car. If you drive 100 miles a week, you can save around £11.50 per week in fuel costs, to set against increased lease / finance costs of around £15 per week.
So for £3.50 a week you will be cutting out tailgate emissions, reducing pollution, and saving yourself from breathing in petrol fumes every time you fill up.
Now that you’ve been convinced to make your next car electric, you’ll need an EV charger.
Many of our customers have installed an iBoost or Immersun or similar to divert excess solar PV into their hot water tank.
If you have an electric vehicle (EV), it makes sense to divert excess electricity into the EV battery. In fact if your hot water is heated by gas, oil or biomass, it makes more sense to charge the car than it does to charge the hot water tank.
