Car Charging Outlet

Get a Free Car Charging 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 your breaker panel must have adjacent available circuits and fall within panel ampacity.  Ideally, the EV plug will be on the same wall as the breaker 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 June 30, 2022.

Solar Energy-Powered Car Charging Outlet

Most auto manufacturers agree: The future belongs to electric vehicles (EV) and plug-in hybrids (PHEV). Florida drivers currently operate around 58,000 electric vehicles – the second-highest number of EVs nationwide, after California.

Whether you already have an electric car or plan to purchase one in the future, a solar car charging outlet is a wise long-term investment. SEM Power offers sustainable, cost-efficient solar car charging solutions in Tampa, Florida.

Why Choose an Electric Car?

Drivers who opt to purchase an electric or hybrid vehicle model enjoy a wide range of benefits. By choosing an EV, you:

  • Cut down on fuel costs and gain independence of fuel price fluctuations
  • Reduce your carbon footprint and embrace a more sustainable lifestyle
  • Take advantage of multiple federal and state incentives

Currently, EVs and plug-in hybrids manufactured starting from 2010 may qualify for a substantial federal tax credit in addition to state and local incentives.

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 solar panel is the Silfab 370 watt Prime panel. 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.

Home Solar EV Charging Outlet Benefits

When you install a solar car charging outlet in your home, you earn the following advantages:

  • A 100% sustainable driving option
  • Long-term energy savings
  • Convenience since you have no need to drive to a charging station
  • Flexibility to charge your electric car from the grid or from your home solar system as needed
  • Increased property value as electric vehicles gain popularity—a ready-to-use solar EV charging outlet is a convenient addition to your property.

How Much Solar Energy Do I Need to Charge an Electric Car?

Typically, most EV models have a battery capacity equaling about 65 kWh, which can sustain a driving range of approximately 220 miles, depending on driving speed, efficiency, and other factors. If you drive about 12,000 miles per year, a standard home PV system of 7-8 solar panels should be enough to keep your EV charged with clean, sun-derived energy on most days.

However, you should also take other factors into account, such as the size of your household, your average electricity consumption, and your typical driving range.

What Kind of Charging Outlet Do I Need for My EV?

The main existing charging system types are as follows:

  • Level 1 (120v outlet) – a basic portable plug-in compatible with a standard 10A wall socket, up to 2.4 kW
  • Level 2 (240v outlet) – a higher voltage wall-mounted charger ranging from 5 kW to 22 kW
  • Level 3 – a fast, powerful charger of 50 kW to 300 kW, suitable for commercial public charging stations

The type of outlet your electric vehicle needs will depend on several factors, including the car model. The two most common home installation options are 120v and 240v outlets.

Generally, 240v outlets (also known as Level 2 charging) will allow your vehicle to charge much faster than a 120v outlet.


Level 1 vs Level 2 Charging
Charger Type Range per Hour of Charge Charge Time
Level 1 4 miles 11-20 hours
Level 2 32 miles 3-8 hours


On average, an EV will need overnight Level 2 charging to reach full battery capacity.

At SEM Power, we install Level 2 240v EV outlets with a NEMA 14-50 outlet type.

Charge time may likewise vary, depending on the level of the EV battery, the type of your EV charger, and the weather conditions in your area. On a sunny day, a 10 kW PV system would take about 6 hours on average to charge an electric car up to 80%.
