It's about half that in less sunny Germany and Central Europe.īut module placement is also key. In sun-drenched parts of Africa, the Middle East, Australia, China, Latin America and the US, a 400-watt module can generate up to 800 kilowatt hours (kWh) of electricity per year. Solar modules produce the most electricity in direct sunlight, which is why they are especially productive in sunny regions and in spring and summer.

The unit can then be simply plugged into a standard wall outlet. The direct current from the solar module is conducted to a small box where it is converted into grid-standard alternating current (AC) by an inverter.

Most importantly the devices don't require installation by a tradesperson. Residents can produce solar electricity themselves with one to three photovoltaic modules hung on balconies or walls, or installed on a terrace, roof or in the garden. Germany too plans to simplify the installation of the devices, with advocates saying they could complement the energy transition if enough people install them. Each of the states has also tried to cut the red tape around installing such units. There is 'a great deal of interest' in the technology in other European countries such as Poland, France, the Netherlands, the UK, Austria, Switzerland and Hungary, said Ofenheusle.

In the megacity of Hangzhou, they're a common sight on large apartment buildings, according to Hans-Josef Fell, president of the Energy Watch Group, a renewables think-tank in Berlin, and former Green Party lawmaker. Small solar systems are also becoming increasingly popular in China. By 2030, he predicts there could be '12 million plug-in solar systems in Germany.' He runs the Berlin-based company EmpowerSource which promotes these relatively cheap mini systems. 'The market is gigantic,' plug-in solar advocate Christian Ofenheusle told DW. The number of small systems registered increased more than seven-fold in the first quarter of 2023 compared to the same period last year, according to official figures. Germany has seen a massive surge in the installation of plug-in solar systems.
