In 2022, Switzerland derived 6% of its electricity from solar power. Studies show that installing solar panels on mountaintops in the could produce at least 16 terawatt-hours (TWh) a year, approaching half of the nation's 2050 solar energy target. Typically, solar panels in Switzerland are mounted on existing infrastructure like mountain huts, ski lifts, and dams, with larger-scale installations in the Alps remaining rare. [pdf]
The Swiss Federal Office of Energy has been surveying the solar market in Switzerland for more than 20 years. Due to this long experience the quality of the data has been maintained, thanks as well to all the installers and distributers who are willing to complete the annual questionnaire.
In 2022, Switzerland derived 6% of its electricity from solar power. Studies show that installing solar panels on mountaintops in the Swiss Alps could produce at least 16 terawatt-hours (TWh) a year, approaching half of the nation's 2050 solar energy target.
For a standard villa with a panel surface area of 50 m2 and a 10 kWh battery, the average price is around CHF 22,000, after deduction of subsidies and tax allowances. How long does it take to recoup your initial investment in a solar system? What are the advantages of a battery-powered solar system for my home in Switzerland?
According to a recent study by the Swiss Federal Office of Energy (SFOE) based on data from a solar potential cadastre ( sonnendach.ch) and meteodata, Swiss houses and factories could generate up to67 TWh of photovoltaic power per year (current power consumption is around 60 TWh).
Typically, solar panels in Switzerland are mounted on existing infrastructure like mountain huts, ski lifts, and dams, with larger-scale installations in the Alps remaining rare. On September 10, 2023, 54% of Valais voters rejected Alpine solar project proposals due to environmental and aesthetic concerns.
new monitoring report of the “Energy Strategy 2050” in 2019 shows that the increase in renewable power production in Switzerland is on track to reach the 4.4 TWh benchmark for 2020 (see graph above – the value for 2019 is 4.19 TWh).The contribution from photovoltaics is thereby above the long-term scenarios.

There is enormous potential for renewable energy in Kazakhstan, particularly from wind and small hydropower plants. The has the potential to generate 10 times as much power as it currently needs from alone. But accounts for just 0.6 percent of all power installations. Of that, 95 percent comes from small projects. The main barriers to investment in renewable energy are relatively high financing costs and an abse. [pdf]
The potential of solar energy in Kazakhstan is estimated at 16% efficiency and 2.5 billion kWh per year, which corresponds to an area of about 10 km2 of solar cells. Solar energy can be widely used in two-thirds of the territory of the Republic of Kazakhstan, with an average efficiency of modern solar panels ranging from 15-25%. The passage does not directly mention the efficiency of solar energy in Kazakhstan being 2.5 billion kWh per year, but rather the potential of it. So, the efficiency value in the passage is the efficiency of the solar cells.
Kazakhstan has significant potential for renewable energy. The wind potential is estimated to be 1.8trn kWh per year, which is close to 10 times Kazakhstan’s current energy consumption, according to UN estimates. Solar energy also has great potential given the number of sunny hours per year, typically between 2,200 and 3,000 hours, implying a capacity of 1,300-1,800kW/sqm per year. Hydro power is another renewable energy source with potential in Kazakhstan.
The geographical position of Kazakhstan makes it suitable for wind and solar energy generation. More than 50% of its territory has a 4–5 m/s wind speed where in some places it reaches 8–10 m/s. In order to establish a wind plant, wind speed needs to be higher than 5 m/s where more than 8–9 m/s are considered as exceptional conditions.
Kazakhstan has areas with high insolation that could be suitable for solar power, particularly in the south of the country, receiving between 2200 and 3000h of sunlight per year, which equals 1200–1700 kW/m2 annually. Both concentrated solar thermal and solar photovoltaic (PV) have potential.
By 2050, Kazakhstan's energy mix is anticipated to consist of at least half of its energy needs coming from non-thermal sources. This plan requires the start of a domestic nuclear energy program and significant growth in non-hydro renewables.
Global trend of tightening carbon regulation presents yet another impetus for broader modernization and systemic reforms of energy sector in Kazakhstan. Kazakhstan should articulate and adopt an official Energy Security Strategy document, guided by these general observations.
