It sure has a big impact on everything here in our planet. For one, it is simply the source of our energy. Plants can’t grow healthy without the help of the sun. Also there are animals that cannot live without energy from the sun.

The sun’s energy, when converted through photovoltaic cells, has the positive impact of being a renewable energy source as contrasted to fossil fuels.
The sun’s energy, as a heat source, can be positively used to to warm water via solar hot water heaters or cook food via solar ovens.
The sun’s energy heats the ocean which results in the wind. The temperature of the oceans, impacted by the sun and the location of the earth relative to the sun, also moderate the earth’s temperature making existence on the earth bearable for us humans.
Negative impacts of solar energy could be when there is an excess of sun that leads to sunburns, or excessively hot cars (that you should not leave animals, humans, or ice cream in).
A negative of solar energy may also be in the negative impact the making of photovoltaic cells has on the environment because of the energy they consume use and chemicals they emit during the manufacturing process.
