Charging an electric car from photovoltaics: it works even in winter when the sun doesn't shine

Integration of photovoltaics and electromobility opens the path to energy independence and long‑term savings. Home charging of an electric vehicle from photovoltaic power is now one of the most efficient ways to use renewable energy sources. While in summer, sunlight can cover most of the household and EV consumption, in winter intelligent power management takes over. This is where modern Czech OlifeEnergy wallboxes, available from SECTRON, excel.

How EV charging from photovoltaics works

A photovoltaic power plant generates energy during the day, and its surplus can be used to charge an electric vehicle. The key is a smart wallbox that monitors real‑time production and automatically starts charging only when the household has available capacity. As soon as the PV system produces more than needed, OlifeEnergy with the SOLAR module begins charging the vehicle. If power generation decreases, charging smoothly adjusts.

This principle allows you to make maximum use of solar energy and minimize grid consumption. The wallbox also communicates with consumption metering, the photovoltaic inverter, and the battery storage unit, creating an efficient, interconnected energy system.

Charging the vehicle even in winter

In the winter months, sunlight intensity and daylight hours decrease, but photovoltaics remain beneficial. Even with lower production, the system can be optimized to use every available watt. The OlifeEnergy SOLAR wallbox can combine multiple energy sources: direct PV generation, battery storage, and grid supply.

When sunshine is insufficient, the system automatically switches to charging from the distribution grid, ideally during low‑tariff periods (e.g., D57d). This significantly reduces total operating costs for the electric vehicle, even outside the main production season.

Dynamic power management = maximum savings

One of the key advantages of OlifeEnergy wallboxes is dynamic power management. This technology adapts charging power to the household’s current load. As a result, the wallbox never exceeds the main circuit breaker limits while making full use of all available energy.

The outcome is safe, smooth, and highly efficient charging without outages or overloads.

Integration into a smart home

OlifeEnergy wallboxes can be easily integrated into home automation systems. Users can monitor electricity production, charging progress, and manage consumption through a mobile app. The electric vehicle becomes an active part of the home’s energy ecosystem — charging when the sun shines and helping optimize household operation.

The future: energy storage and Vehicle‑to‑Grid (V2G)

The next step in this evolution is Vehicle‑to‑Grid (V2G) technology, enabling two‑way energy flow between the vehicle and the grid. The EV thus becomes not only a consumer but also an energy source. Excess solar electricity can be stored in the car’s battery and later used to power the home or be fed back into the grid.

The combination of photovoltaics, battery storage, and a smart wallbox represents the future of self‑sufficient energy for homes and businesses alike.
