With fuel prices expected to keep rising in 2026, more and more drivers in the Var and Alpes-Maritimes are looking for ways to reduce their mobility costs. Switching to an electric vehicle, combined with a solar installation by Edmond Solutions, is increasingly appealing thanks to its potential for significant savings and long-term sustainability. A clear, objective analysis of costs, available incentives, and practical limitations helps determine whether this investment truly meets today’s and tomorrow’s financial and environmental challenges.
Why Rising Fuel Prices Are Reshaping Driving Habits in 2026
The year 2026 is set to be marked by another sharp rise in fuel prices. Several factors are driving this trend: increasing environmental taxes, ongoing geopolitical tensions in the oil market, and the gradual depletion of fossil fuel resources. This combination is directly impacting the budgets of households and businesses in the Var (83) and Alpes-Maritimes (06), prompting many to rethink how they travel.
As a result, interest in electric mobility is growing rapidly. Electric vehicle sales are surging across France, and with fuel costs becoming increasingly unpredictable, more drivers are evaluating the long-term value of switching to an electric vehicle and charging at home using solar energy. This solution is now seen as both a cost-effective and sustainable alternative. Edmond Solutions, an RGE-certified installer based in Fréjus, has been supporting households for over 15 years in their energy transition.
Electric Vehicle Profitability in 2026: Key Factors to Consider
Assessing the profitability of an electric vehicle requires a precise calculation of the Total Cost of Ownership (TCO). Several factors come into play, starting with the higher upfront purchase price of new models—although this gap is gradually narrowing thanks to increased competition and more mature technologies.
In everyday use, the real savings come from a significantly lower cost per kilometer compared to petrol vehicles. Maintenance costs are reduced (no oil changes, less wear on brake pads due to regenerative braking), and most importantly, electricity is far cheaper than fuel. Home charging—especially when combined with a photovoltaic system installed by Edmond Solutions—further enhances these savings.
Buying an Electric Vehicle and Installing Solar: What Investment and What Return?
The higher upfront cost remains a major barrier to purchasing an electric vehicle. In 2026, the average price gap between a new petrol car and its electric equivalent still ranges from €5,000 to €10,000. However, this difference should be weighed against long-term savings and the range of available incentives.
On the solar side, the average cost of a 4 kWp residential self-consumption system installed by Edmond Solutions is between €7,000 and €8,500. A home EV charging station typically costs between €800 and €1,500, excluding potential subsidies. These investments should be considered as part of a long-term strategy focused on overall profitability.
Payback Period: How Incentives and Savings Offset Your Investment
With the various incentive schemes available, the remaining cost is significantly reduced for many households. The CEE grant (formerly the ecological bonus) for purchasing a new electric vehicle now ranges from €3,500 to €5,700 depending on income, with an additional bonus of €1,200 to €2,000 for vehicles equipped with a European-made battery (source: French Ministry for Ecological Transition, November 2025).
On the solar side, the 2026 self-consumption premium stands at €80/kWp for systems up to 9 kWp (source: CRE, Q1 2026), while regional subsidies often reduce the overall investment by 10% to 20%.
In everyday use, the lower cost per kilometer significantly accelerates payback. For a household driving 15,000 km per year, the combined investment in an electric vehicle and a solar system typically becomes profitable within 5 to 8 years.
The table below illustrates the purchase cost and estimated payback for a typical household:
Equipment | Gross Cost (€) | 2026 Incentives (estimated) | Net Cost (€) | Estimated Payback Period |
|---|---|---|---|---|
Electric Vehicle | 35 000 | CEE Grant: -€3,500 to -€5,700 | ~29 500 to 31 500 | ~7 to 9 years |
4 kWp Solar Panel System | 8 000 | Prime autoconso : -€320 | ~7 680 | ~8 to 10 years (Var/PACA) |
EV Charging Station | 1 200 | Potential Local Incentives | ~1 020 to 1 200 | ~5 years |
What Are the Real Savings of Combining an Electric Vehicle with Solar Panels?
When charging is mostly powered by solar self-consumption, the cost per kilometer drops significantly. For a vehicle consuming 15 kWh/100 km, the energy cost falls to under €2 per 100 km when electricity mainly comes from solar panels, compared to €13.20 for a petrol car at a fuel price of €2.20/l.
Home charging also provides greater flexibility and independence from the public grid, whose prices may continue to rise in the future depending on energy policies.

Solar Self-Consumption: Towards Nearly Free Mobility?
In the Var and Alpes-Maritimes, homeowners benefiting from the strong sunshine of the PACA region can cover between 60% and 80% of their annual EV charging needs through their own photovoltaic production. A household driving 15,000 km per year can therefore save up to €2,400 annually compared to a petrol vehicle, significantly enhancing the economic advantage of combining electric mobility with solar energy.
Depending on future changes in grid electricity prices, this cost gap could widen even further over time.
Cost per Kilometer Comparison: Petrol vs. Fully Electric vs. Solar-Powered Electric
Vehicle Type | Fuel / Energy | Average Consumption | Cost per 100 km |
|---|---|---|---|
Fuel | €2.20 per liter | 6 L/100 km | €13,20 |
Fully Grid-Powered Electric Vehicle | €0.25 per kWh | 15 kWh /100 km | €3,75 |
Electric Vehicle + Solar (Edmond Solutions) | €0.08 per kWh | 15 kWh /100 km | €1,20 |
These figures highlight the clear competitive advantage of combining an electric vehicle with partial or full solar-powered charging. This cost gap helps explain the growing interest in electric mobility as fuel prices continue to rise.

Limitations and Key Practical Considerations Before Making the Switch
Several factors should be carefully considered before making the switch. The real-world range of electric vehicles depends on the model and is often still lower than that of petrol cars, although it continues to improve. Charging time—ranging from 30 minutes on a fast charger to up to 8 hours on a standard outlet—requires some adjustment in usage, especially for long-distance travel. In addition, fast-charging infrastructure can still be uneven depending on the region.
Installing solar panels requires a suitable roof, ideally unobstructed and south-facing—conditions that can be difficult to meet in apartment buildings. Solar production also varies depending on weather conditions, which often makes a hybrid approach (solar + grid electricity) necessary. Finally, the initial investment is only offset after several years of savings, requiring careful financial planning.
