The four types of solar energy utilization are:

1. Passive solar: This type of solar energy utilization involves designing buildings in a way that they can naturally heat and cool themselves without the need for electrical equipment. This can be achieved by using certain materials, orienting the building in a certain way, etc.

2. Active solar: This involves using mechanical or electrical equipment to convert the sun's rays into usable energy. This can include solar panels, solar water heaters, etc.

3. Solar thermal energy conversion: This involves using the heat from the sun to generate electricity. This is usually done by using mirrors or lenses to concentrate sunlight onto a small area, which is then used to heat a fluid and produce steam that drives a turbine.

4. Photovoltaic cells: These are devices that convert sunlight directly into electricity. They are made of semiconducting materials, and when sunlight hits these materials
