Solar energy means energy from sunlight, in any form.

Some forms of solar energy include

Some forms of solar energy such as heating are well-adapted to low-technology appropriate construction, while others such as photovoltaic cells for the production of electricity are typically mass-produced in high-tech capital-intensive factories.

The relatively mild heating of a flat plate collector can be used for:

Optimum orientation of solar energy harvesters
Optimum tilt of windows by latitude

According to Village Earth, water heated in a normal flat plate collector does not boil.[1]

So to Pasteurize water and to cook at high temperature cannot use flat plate collectors, but must use more complicated concentrating collectors that require frequent adjustment to keep them pointed at the sun, such as:
