electric vehicle Outlet

Get a Free Electric Vehicle Outlet

When you secure your residential solar install through SEM Power, we will install a level two 240v Electric Vehicle (EV) outlet at no additional charge! It does need to be requested prior to the permit approval and ideally, the EV plug will be on the same wall as the fuse panel. It can be placed in another location, but would be subject to additional charges. The outlet type is a NEMA 14-50. This promotion runs through December 31, 2021.

How Many Solar Panels Do I Need to Charge my Electric Vehicle?

Most EV’s average about 3 to 4 miles of range per kWh of electricity stored in the vehicle’s battery. This example will use 3 miles of range per kWh. Let’s assume a person has a 30 mile commute every day, that would mean that if the homeowner wants to charge at home every night they would need 10 kWh of electricity to re-charge, or 50 kWh per week, 200 kWh per month, or 2,400 kWh for a 7,800 mile commute per year. 
Another way to calculate it would be to assume that you drive your car a total of 12,000 miles per year, which is equivalent to consuming 4,000 kWh per year. This is the number we will use to calculate the size of the required solar panel array.

The industry standard to obtain the solar panel photovoltaic (PV) system size you need for a specific production is to divide the annual kWh consumption by a coefficient of 1.5.

Using these numbers in our equation, 4,000 kWh/1.5 = 2.67 kW PV system size.


SEM Power’s go-to panel is the REC 355 watt Alpha Series.  This is the panel we will use for our example below.


2.67kW PV total system size / 355w panels = 7.5 panels. So there we have it.  If you buy an EV and drive 12,000 miles per year, you will need 8 solar panels to avoid purchasing kW from your energy provider.
