How to get your installations winter-ready with the right home battery

During the winter months, solar panels generate less energy thanks to shorter days and weaker sunlight, while household energy consumption usually rises. For installers, this is the perfect moment to add value for customers. By recommending the right home battery, you help your customers use their self-generated energy more efficiently, even in colder months.

The winter-season challenge

In winter, solar panel yields tend to drop: fewer daylight hours, more clouds, and colder conditions can impact output. At the same time, energy demand increases: lights are on earlier, heating or heat pumps run longer, homes are in more intensive use. The result: customers rely more on the grid or expensive peak tariffs.

Smart battery storage as an energy buffer

By storing energy when the sun is shining, and using it later, you maintain the value of the solar installation even in winter. A home battery helps avoid peaks, increases self-consumption, and reduces reliance on the grid. It also strengthens the sales pitch: the installation isn’t just summer-ready, it's winter-ready too.

Choosing the right battery

Every customer’s situation is different: consumption patterns vary, system types differ (existing installation, with or without current storage), available space, brand or technology preferences, and future expansion (e.g., e-mobility). Key factors include capacity (kWh), power (kW), compatibility with inverter, warranty, software/monitoring, winter temperature conditions, etc.
