Charging Electric Vehicles with Solar in Egypt: A Practical Guide
Can you charge your EV from rooftop panels? How many panels you need, home versus commercial charging, and how to integrate chargers with your plant.
GPS Engineering Team
Electric vehicles are gradually spreading in Egypt, and with them a logical question: why charge from the grid if you have panels on the roof? Solar EV charging makes almost every kilometre you drive nearly free in energy terms.
Key takeaways
- An EV uses roughly 15–20 kWh per 100 km.
- 3–4 kW of panels usually covers average daily driving.
- Daytime charging uses solar output directly.
- Smart chargers can charge from solar surplus automatically.
How many panels do you need?
| Daily driving | Approx. daily energy | Required array |
|---|---|---|
| 30 km | 5–6 kWh | about 1.2 kW |
| 60 km | 10–12 kWh | about 2.5 kW |
| 100 km | 17–20 kWh | about 4 kW |
Home charging
- A 7.4–11 kW wallbox with solar-surplus charging.
- If the car is home during the day, it charges straight from the panels.
- If it charges at night, net metering offsets the daytime energy you exported.
Charging at facilities
Hotels, malls and factories can offer charging for guests and staff under solar carports — an attractive service and a potential revenue stream.
What about batteries?
A hybrid system with a home battery stores daytime energy to charge the car at night, but adds cost. For most grid-tied cases, net metering is cheaper. See our battery guide.

GPS engineers have designed and built solar plants across Egypt for 15+ years. Here they share what they learn in the field.
Frequently asked questions
Can a car charge directly from panels without an inverter?
No. The car needs a dedicated charger connected to household power or a hybrid inverter, with suitable protection.
Does fast charging affect a home plant?
Home chargers of normal ratings fit home systems; very fast DC chargers need a study of the connection capacity.
