Seasonality of quarterly performance due to reduced winter solar irradiation
First written in FY2017-Q4. 2 of 5 entries say "Restated". Latest entry: FY2026.
The whole theme swung hardest in 2018: 3 of 8 companies on the "Worse" side.
3 other companies' latest entry also says "Mitigated".
- FY2026MitigatedAnnual report
「As of 31 March 2026, generation across the Group has increased, and the impact of seasonal concentration on the Group's results is limited.」
Although the seasonality of weather-dependent power sources continues to be described, the impact on results is explained as limited due to increased generation. - FY2018-Q4RestatedAnnual report
「Solar power plant generation declines in winter, when solar irradiance is low. Accordingly, third-quarter consolidated sales tend to be lower than in other consolidated quarters.」
The seasonality of lower third-quarter sales due to reduced winter solar irradiance has been reconfirmed. - FY2018-Q2RestatedAnnual report
「Solar power plant generation increases from April to August, when solar irradiance is high. Accordingly, first-quarter consolidated sales tend to be higher than in other consolidated quarters.」
The seasonal variation in quarterly results driven by the season and solar irradiance has been reconfirmed, with sales tending to be higher in the first quarter due to increased generation from April to August, in addition to the previous explanation that sales decline in winter. - FY2017ReframedAnnual report
「In general, power sources that use renewable energy derived from natural sources, such as solar and wind, experience fluctuations in power generation according to the season in addition to daily changes in weather conditions.」
The explanation has been reframed from a focus on lower winter solar irradiance to the broader seasonal variability risk of weather-dependent power sources, including solar and wind. - FY2017-Q4First statedAnnual report
「Solar power generation declines in winter, when solar irradiation is lower, so revenue in the third quarter of the current consolidated fiscal year tends to be lower than in the other quarters.」
It explains the seasonal pattern whereby lower solar irradiation in winter causes third-quarter revenue to be lower than in other quarters.
