Step by step production of crystalline solar panels

With a share of around 11% of electricity generation across the EU, solar power will overtake coal-fired generation for the first time in 2024. For photovoltaics to continue to gain importance, solar modules must be produced efficiently, economically and in large quantities. Join us for a look at what such a production process looks like.

What is the return on investment for battery storage?

Electricity costs for businesses remain high even after the energy crisis and there is no reason for them to fall in the coming years. Investing in reducing energy costs therefore makes more sense than ever. However, the key is to combine photovoltaics with battery storage so that the business can "consume" as much of the electricity generated as possible in its own operations.
