A solar calculator typically uses photovoltaic cells to convert sunlight into electrical energy. This type of energy is clean and renewable, making solar calculators an environmentally friendly choice. It allows the calculator to function as long as there is enough light available.
In the SI, the same is used as for any other kind of energy: the Joule.
