Solar panels to charge EV directly?


Ste78

Recommended Posts

Hello,

ย 

I drive 60km a day and my EV car is always at home during the day;

usually charged with the normal slow cable (cannot install wall charger since I am renting the house), not a problem leaving connected many hours.

ย 

Cost per month is quite limited, butย I was wondering if I can charge using the daylight:

ย 

would it be possible to install some solar panels to plug to the car "directly",or need inverter / battery / others?

ย 

I mean using the real time output, no need storage for using electricity for house.

ย 

Any advise is appreciated

I wouldn't think practical, or economical if practical.ย  At peek time, if sunny, most you're going to get from any one panel is 500-700w per hour, and need an inverter to use.ย  Consider your slow charging cable is 2-3+kWh per, and you see the issue.

60km I think is around 8Kwh consumption (~35b /day, 1000b /month).

ย 

With 1 panel 1000W costing 1500b, chargin 8Kwh would not take 8 hours?

ย 

Even if I not spend much money, those 1500b could be saved in one and a half months.

ย 

Or you meaning other equipment is necessary?

Where are you getting 1,000W panels for 1,500 Baht??

ย 

A 1kW panel would generate about 3-4kWh per day of decent sunshine. It would also be about 3m x 2m and weigh ...

ย 

Direct EV charging (DC) from solar is an emerging technology = $$$

ย 

Easier would be to use a simple grid-tie inverter to supplement your grid energy usage whilst using the "granny charger".

Do you have an actual link for that?

ย 

850mm x 680mm = about 0.5m2ย 

ย 

With the absolute maximum insolation from our local star being about 1kW per m2ย that panel is 200% efficient!!!

ย 

Most real panels are about 20% efficient.

ย 

Something doesn't add up.

ย 

you may be right about efficiency or the need to verify in person.

I just picked up the first results on Lazada

An EV charged up by solar power. A green dream.

If your EV support bidirectional charging you can use the EV to power your home when the panels are not producing.
