Direct solar power generation is when sunlight is used to heat something or to generate electricity directly (e.g. using a solar panel)
Once you understand the above you will see that hydroelectric power is obtained when water from a high elevation moves through a turbine to a lower elevation - the energy used is gravity (potential and kinetic energy). However if you think about it what gets the water up in the high river or lake in the first place - the energy that does this is the heat form the sun evaporating the water which forms into cloud then comes down as rain. Therefore although the hydro electrical energy is gravity driven we are in fact using the energy that came form the sun (that raised the water) with hydroelectric power but this energy comes to us in an indirect path from the initial sunlight.
Some types of non-polluting power generation include solar power, wind power, hydroelectric power, and geothermal power. These sources generate electricity without emitting greenhouse gases or other pollutants that harm the environment.
Because solar energy runs the water cycle, giving rise to precipitation, and then the rain water flows into the reservoirs of dams.

Hydroelectric power and solar energy.
Hydropower is considered an indirect form of renewable energy because it relies on the water cycle to generate electricity. Solar and wind power are examples of direct renewable energy sources that rely on their respective natural sources for power generation.
Photons from the sun contribute to the generation of power from solar cells.

solar energy. Solar energy is derived from the sun's rays and can be continuously harnessed for electricity generation through solar panels. It is considered a renewable resource because the sun is an abundant and constant source of energy.
Hydroelectric is ultimately solar power. The water that powers the dams is brought in from the ocean by solar evaporation that returns to the earth in the form of rain or snow. Aside from the costs (not just money but also environmental) of building dams, hydroelectric power is free for the taking.
Wind power is an indirect form of solar power because wind is ultimately driven by the sun's uneven heating of the Earth's surface. As sunlight warms the atmosphere and land unevenly, it creates temperature differences that lead to atmospheric pressure imbalances and the generation of wind. Thus, wind power can be seen as a result of the sun's heat driving the Earth's weather systems.
Wind power, solar panels, hydroelectric, etc.
The best form of solar power generation is through much more advanced and dangerous technology. For your home though, solar panels are a great form of solar power generation, and although not totally reliable, very good for environment and saves costs.
