At a time when the energy transition is more necessary than ever, the solar generator is a relevant and promising solution. These devices offer a renewable and sustainable source of energy, while maximising energy autonomy.

What is a solar generator?

It’s a device that converts solar energy into electricity, using solar panels and an energy storage system. It’s a clean, renewable solution that can be used to power homes, industrial facilities or even remote areas with no access to the electricity grid.

The benefits

There are many advantages to solar generators. They reduce CO2 emissions, offer energy autonomy and are cost-effective in the long term. What’s more, they are silent and require little maintenance, unlike traditional generators that run on fossil fuels.

How a solar generator works

The operation of a solar generator is relatively simple. Solar panels capture sunlight and convert it into electricity. This energy is then stored in batteries for continuous use, even when the sun is not shining.

Calculating the profitability of a solar generator set

The initial cost of a solar generator may be high, but its long-term use makes it profitable. For example, for a 5kW generator, the average cost is around €15,000. Assuming a lifespan of 20 years and average use, the savings in electricity bills can be as much as €30,000.

The future of solar generators

The future of solar generators is bright. According to a study by Global Market Insights, the solar generator market could reach $1.5 billion by 2026, with an annual growth rate of over 7%.


The solar generator is undoubtedly a major innovation in the field of renewable energy. Its potential for reducing carbon emissions, energy autonomy and cost-effectiveness puts it at the heart of tomorrow’s energy transition.

How does a solar generator work?

A solar generator is a device that combines solar panels, an inverter and an energy storage system, usually in the form of batteries. It works in several main stages:

Collecting solar energy: Solar panels, made up of photovoltaic cells, capture the sun’s energy. These cells contain semi-conductors which, when exposed to sunlight, produce a direct current (DC).
Energy conversion: The direct current generated by solar panels is not directly usable in our domestic appliances, which generally operate on alternating current (AC). This is where the inverter comes in, converting the direct current into alternating current.

Energy storage
Not all the electricity produced by the solar panels is used immediately. Surplus electricity is stored in the generator’s battery system. This storage allows the solar electricity produced during the day to be used to power electrical appliances at night or on cloudy days.
Energy use: The electricity stored in the batteries, or that generated directly by the solar panels (if consumed during sunny hours), is used to power the electrical appliances connected to the system.
