Vehicle-Integrated Solar Charging

Vehicle-integrated solar charging uses photovoltaic panels built into the vehicle roof to generate DC electricity that charges the battery directly. This is the approach used in WOX Zeny. The key advantage is that the solar system travels with the vehicle — it generates energy wherever the vehicle is parked in sunlight, without requiring any external infrastructure. The limitation is panel area: a vehicle roof can accommodate significantly less panel area than a rooftop installation.

• No external infrastructure required
• Generates energy wherever the vehicle is parked
• Limited by vehicle roof area
• Supplements but does not replace plug-in charging

Home Rooftop Solar Charging

Home rooftop solar charging uses a home solar system to generate electricity that powers a home EV charger. The vehicle is charged through a standard AC charging connection. Home solar systems can accommodate much larger panel areas than a vehicle roof, enabling higher daily energy generation. The limitation is that the vehicle must be at home during daylight hours to benefit from home solar charging.

Solar Carports

Solar carports integrate solar panels into parking canopy structures, generating electricity that can be used to charge EVs parked beneath them. Solar carports are increasingly used in commercial, fleet and public parking applications. They combine the benefits of a larger panel area with EV charging infrastructure at a fixed location.

Grid Charging

Grid charging uses electricity from the public grid to charge the vehicle through a standard charging connection. Grid charging is the most reliable and predictable charging method — it is available regardless of weather, season or time of day. In regions with a high proportion of renewable energy in the grid mix, grid charging can also be a low-carbon option. Grid charging remains the primary charging method for all current EVs, including solar-assisted EVs.

Battery Storage Integration

Battery storage systems — such as home energy storage batteries — can be combined with home solar to store excess solar energy for use when solar generation is low (at night or on cloudy days). This enables a higher proportion of EV charging to come from solar energy, even when the vehicle is charged at night. Battery storage integration is a growing area of the home energy market.

Choosing the Right Approach

The best solar charging approach depends on your situation. Vehicle-integrated solar is the most convenient option — no infrastructure needed, the system travels with the vehicle. Home solar charging offers higher generation potential for vehicles charged at home. Solar carports provide the highest generation potential at a fixed location. For maximum solar charging benefit, a combination of vehicle-integrated solar and home or workplace solar charging is ideal.

• Vehicle solar: convenient, no infrastructure, limited area
• Home solar: higher generation, requires home charging setup
• Solar carport: highest generation, fixed location
• Grid charging: most reliable, always available
• Battery storage: extends solar use to non-solar hours
