Electric cars

Post by Termites Dream » Thu Feb 11, 2021 9:22 am

For those considering an electric car, I thought some maybe interested in this evaluation and comparison.

For information as to who Edmunds are;

Edmunds was founded by Ludwig Arons in 1966 as Edmunds Publications, a publisher of printed booklets consolidating automotive specifications to help car shoppers make buying decisions. In 1988, the company was purchased by Peter Steinlauf whose family has owned a majority stake since.
Key people: Avi Steinlauf, CEO
Industry: Automotive information services
Founded: 1966
Headquarters: Santa Monica, California

People considering to buy a electric car should have a PV solar system installed (5kWp) in order to charge them at their premises. Only this way does something good for the environment as in CY most of the electricity from EAC is produced environmentally harmful with heavy oil...

If, like most working people, the owner comes home at night and goes off to work in the morning, he won't get very far charging it from a photovoltaic system. :-)

As we are in Cyprus, most working people (nearly all of them) driving home midday, and spend quite a time there for lunch and a rest (siesta).
This is the perfect time to charge the E-car as midday is the highest production from PV modules...
Just watch the Green Air webcam midday's and see the stop and go not only uphills!

Well the shop workers don't drive home at midday, and neither do most of the people in the building trade..

The output from PV modules drops at temperatures above 25° C. You will need to cater for about 15 percent extra output from your PV system when the temperature of the junctions exceeds 40° C. They can even reach higher temperatures than the ambient from direct radiation; it is not impossible for the junctions to reach higher than 50° C. Your sentence is perfectly correct when the ambient temperature is lower than 25° C.

But the majority of working people are not home for long during the daytime..

The highest production my BiL's PV system in Germany was on a very cold but sunny day in February.

Exactly! A bright late-winter and cold day is the ideal. The output actually rises by as much as 5 to 10 percent under those circumstances. The nominal output of a PV system is at 25° C ± the manufacturer's tolerance. It is well known that the output of a PV panel goes down as the temperature goes up and vice versa.
