Germany’s mobility transition is entering a new phase: electric cars are no longer just a means of transport—they’re becoming part of the energy system. Thanks to Vehicle-to-Grid (V2G) technology, EVs can feed surplus electricity back into the grid—allowing you to earn money with your electric car. Combined with a photovoltaic system (PV), your home transforms into an intelligent power plant. In this article, PVPro Solar explains how V2G works and how you can benefit from it.

What Does Vehicle-to-Grid (V2G) Mean?

Vehicle-to-Grid (V2G) is an innovative technology that enables electric vehicles (EVs) not only to charge from the grid but also to feed energy back into it. This turns your EV into a mobile energy storage system—a smart, efficient way to generate passive income from vehicle ownership. The stored power can be used during peak demand hours to support the grid or to power your home, reducing reliance on traditional fossil-fuel-based power sources.

This approach is especially effective when combined with a photovoltaic system, such as those offered by PVPro Solar. Solar power generated during the day can be temporarily stored in the EV and then shared, sold, or used when needed—creating extra savings and flexibility for owners and drivers.

How Does V2G Work on a Technical Level?

Implementing V2G involves several qualified components and installations:

• A V2G-capable electric vehicle: Not all EVs support bidirectional charging. Qualified models include the Nissan Leaf, Hyundai IONIQ 5/6, Kia EV6, BYD models, VW ID series (from 2026), and the Renault ZOE (with updates). Always check with the manufacturer whether your car is eligible for V2G programs.
• A bidirectional wallbox charger: This charger allows energy to flow both into and out of the EV. Brands like Wallbox Quasar and Indra offer affordable, easy-to-install solutions, especially for city homes or business locations.
• An intelligent energy management system: This system decides when to charge or discharge the EV, depending on grid load, electricity rates, incentives, and home demand. With dynamic program settings, drivers and homeowners can maximize their earnings based on real-time conditions.
• A photovoltaic system: A properly installed PVPro Solar system completes the solution by supplying renewable energy that can be stored, used, or shared through the EV.

What Are the Benefits of V2G for Homeowners?

Generate Additional Revenue

By feeding electricity back into the grid, homeowners can earn passive income. Many utility companies offer incentives, feed-in tariffs, or bonuses for flexibility and participation in grid-balancing programs.

Example: A household with a 10 kWp PV system, a home battery, and a V2G-compatible EV could generate up to €100 per month, depending on tariffs, location, and usage patterns. Businesses offering V2G-compatible chargers may also attract more customers.

Increase Energy Independence and Savings

V2G provides interim storage for surplus solar energy, which can later be used during expensive peak hours—offering cheaper energy for driving or home use. This reduces your dependency on the grid, decreases your electricity bills, and improves your long-term savings.

Improve Grid Stability and Support the Energy Transition

By sharing stored power during demand peaks, EVs help reduce strain on the grid—lessening the need for fossil-fuel backup stations. V2G fosters a decentralized, green energy grid—especially when more individuals and companies participate in this ecosystem.

Legal Framework for V2G in Germany

In Germany, V2G is transitioning from pilot projects to real-world applications. However, regulations, taxation, and remuneration are still evolving.

Current status (2025):

• Bidirectional charging is permitted, and owning a V2G-compatible vehicle makes you eligible for various programs.
• Grid feed-in requires approval from your local grid operator.
• Funding programs for smart infrastructure are expanding, especially in urban areas.
• Feed-in income may be taxed depending on ownership type and business use.

PVPro Solar guides you through the legal process—helping with registration, subsidy applications, and compliance.

Which Electric Vehicles Support V2G?

Not all EVs are equipped for bidirectional charging. Known V2G-compatible models include:

• Nissan Leaf
• Hyundai IONIQ 5 / 6
• Kia EV6
• BYD models
• VW ID series (planned from 2026)
• Renault ZOE (with updates)

PVPro Solar provides expert advice to ensure smooth communication between your EV, wallbox, and solar system.

Is V2G Economically Viable?

Let’s look at a practical example:

• A 10 kWp PV system generates approx. 9,000 kWh per year
• 3,000 kWh of that is stored in the EV and fed back to the grid at €0.10/kWh → €300 earnings
• Additionally, reduced grid usage of 50–80% saves you €800–€1,200 annually

With PVPro Solar’s all-in-one solution—including bidirectional wallbox, intelligent EMS, and low-maintenance design—your investment typically pays off in 8 to 10 years, depending on usage and local tariffs.

Pairing with Home Battery Storage: Even More Flexibility

Adding a home battery improves flexibility during:

• EV absence (e.g., while driving or parked elsewhere)
• Emergency situations like power outages
• Times when you want to prioritize home usage

Your EV can also function as an emergency power source via island mode. PVPro Solar’s load management system ensures optimized energy distribution between EV, battery, and your home.

Subsidies for V2G and PV Systems

Starting in 2025, several government-backed grants will support:

• PV systems with battery storage
• Bidirectional wallboxes
• Smart energy management systems (EMS)
• V2G-compatible vehicle charging ports

PVPro Solar helps you find available subsidies, manage the full application process, and choose the best technology for your needs.
