Although analysts predict that energy prices may also increase in the years to come, in general, it costs more to fill up an internal combustion engine (ICE) vehicle with gas than it does to charge an electric vehicle (EV) at home. This is particularly true if you are careful to charge at off-peak times, when electricity may be less expensive, or if you run your charger off of solar panels on your house.
Switching to solar panels for EV charging can lead to significant cost savings over time compared to traditional grid charging. Here’s a succinct cost comparison:
| Cost Factor | Solar Panel Charging | Traditional Grid Charging |
| Initial Setup | $10,000 – $15,000 | $0 – $500 |
| Average Electricity Rate | Free (sunlight) | $0.13 – $0.20 per kWh |
| Maintenance (Annual) | $100 – $200 | $0 – $50 |
| Long-term Savings | High (over 25 years) | Moderate |
According to the US Energy Information Administration, as of January 2023, the national average cost of electricity is approximately $0.15 per kWh for residential customers. This rate varies by state, ranging from 9-10 cents to 25-30 cents per kWh, with Hawaii being an outlier at 45 cents per kWh.
Taking the Tesla Model 3 as a case study, which has a 60 kWh battery, the cost to fully charge it at the average rate of $0.15 per kWh is about $9.00. If we assume an average of 8 full charges per month, the monthly cost would be around $72, amounting to an annual expense of $864 for traditional grid charging. In contrast, solar panel charging, post-initial setup, incurs negligible electricity costs, underscoring the substantial long-term savings and sustainability of this option.
The message “Battery power very low” will appear as your battery life nears its end. decreased cooling and heating If you continue driving, a second warning that reads, “Car shutting down, pull over carefully,” will show. A short while later, the car’s power will fail and you’ll hear an alert.
Because some models can be carried while others cannot, it is recommended to have the car loaded into a flat-bed truck to either be taken home or to a charging station. Roadside groups are looking into installing roadside emergency chargers in their cars, and it appears that as the number of EVs rises, so will the use of these chargers.
Even the lithium batteries used in electric vehicles shouldn’t be entirely depleted, according to technical standards. To prolong lengthy battery life, it’s a good idea to discharge batteries to a maximum of 80%.
