Installing a solar carport for a Tesla car
One perfect way to use solar panels in charging your electric vehicle, like a Tesla car, is to use solar panels as a carport. This way, you will not only charge your EV but also, keep it under the solar panels’ shade.
What do you need to install a solar carport for your Tesla car?
Let us say, for example, you drive an average of 50 miles each day. Then, by using the table above you will require 24 solar modules with 400 Watts capacity. Then, you will also need a steel carport structure to keep your solar panels in place. Here is the list of materials you will need to install this carport.
|Solar Panels 400-Watts||24||nos.|
|6 sq. mm. DC Cables CU||50||meters|
|8kW Single-Phase Solar Inverter||1||no.|
|10 sq. mm. or #8 AWG CU AC Cable||30||meters|
|Tesla Wall Connector||1||no.|
Sustainable Transportation: Building a Solar Carport for Your EV
Firstly, you need to build the foundations for the steel carport structure. You may hire a professional contractor to do the entire installation. But, we will still walk you through the installation process in this article.
After building the foundations, you can now start installing the carport structures.
Make sure you install it in such a way that the tilt will be facing where the Sun will likely hit the solar panels the most. In most cases, this pertains to the Southward direction as much as possible.
Once the structures are fixed, you may start placing the mounting rails on top of it. There will be a total of 6 rails that are spaced accordingly along with the carport structure. This will hold the solar panels in place.
Optimizing Solar Panel Arrangement for Charging Your Electric Vehicle
The next thing to do is to install the solar modules in a portrait arrangement and 3 rows. Each row will have 8 panels. The end and mid clamps will be used to fix the solar panels on the railings. The carport dimension will be approximately 6.1m x 8.2m, enough to give shade to 2 electric vehicles.
You would also require an 8 kW solar inverter to convert the DC electricity to AC. This inverter can be fixed into the carport structure itself. Solar DC cables with 6 sq. mm. size will be used to connect solar panels to the inverter. Make sure to revisit the voltage drop calculation for the cables to minimize the power loss.
Do not forget about the MC4 connectors that will be fixed on both ends of the DC cables. The solar panels can be grouped into 2 strings, wherein each will have 12 modules connected in series.
Once the DC cables are secured and connected to the inverter, we can start with the wiring on the AC side. Connect 3 sets of 10 sq. mm. or #8 AWG CU AC Cable from the inverter to the metering panel. Another set of AC cables of the same size will then be connected to the house’s mains. Then lastly, install the Tesla charger near the carport.
How much does the electric bill go up with a Tesla?
It is difficult to determine exactly how much a person’s electric bill will go up with a Tesla, as this can vary depending on a number of factors. Some of the key factors that can impact the cost of charging a Tesla include the size of the battery, the local cost of electricity, and how often the vehicle is charged. On average, it is estimated that the cost of charging a Tesla can range from around $15 to $55 per month for a small battery, to up to $100 or more for a larger battery. However, it is important to note that these estimates can vary and that it is best to consult with your local utility provider for accurate information on the cost of charging a Tesla.
If we assume the average pricing of national electric companies is still at 0.13$ per kWh, charging efficiency of 85%, and an average of 60 miles driven every day, then you have to account for an increase of 2.38$ each day or 71.40$ monthly on your electric bill. From a cost per distance traveled perspective, it will be 3.97$ per 100 miles of mixed city and freeway driving.
However, this cost can be considered savings when you install solar panels to charge your EV. This means you can generate electricity for your Tesla car instead of just relying on the national electric utilities for energy. So, think about charging a Tesla with Solar Panels.
How much does a Tesla home charger cost?
Tesla home chargers are available from Tesla for $500. You can choose between two connector options. The first one is the Mobile Connector option. This comes with a 24-foot-long cord that you can unplug and take with you when you leave the house. The second one is called the Wall Connector. According to Tesla, this is the most dynamic wall charging equipment for their various EV models.
Note: When charging your Tesla car, always refer to the original manufacturer’s manual for instructions. Always keep yourself and your car safe and away from any harm.
