Solar influence on the Earth System | Sun Climate
Continuous observation of TSI from space started since 1979. The observations reveal that the TSI varies with the 11-year solar cycle. From solar minimum to solar maximum, there is an increase of about 0.1% in the TSI, indicating that solar energy flux is not a true constant, contrary to the use of the term "solar constant".
Effect of Light Intensity
Changing the light intensity incident on a solar cell changes all solar cell parameters, including the short-circuit current, the open-circuit voltage, the FF, the efficiency and the impact of series and shunt resistances.The light intensity on a solar cell is called the number of suns, where 1 sun corresponds to standard illumination at AM1.5, or 1 kW/m 2.

How to identify a strong vs weak relationship on ERD?
The relationship Room to Class is considered weak (non-identifying) because the primary key components CID and DATE of entity Class doesn''t contain the primary key RID of entity Room (in this case primary key of Room entity is a single component, but even if it was a composite key, one component of it also fulfills the condition).. However, for instance, in the …
