Passive solar energy is affordable energy at its best. So what exactly is passive solar energy? Passive solar energy is the ability to harness sunlight and convert it to energy without using active mechanical machines. There are definitely pros and cons of solar energy with passive solar energy being one of the biggest upsides. Passive solar energy designs in building and homes are making affordable solar energy a reality. Passive solar is used for low-energy needs to provide heat and cooling. Some passive energy systems use low-power technologies to make solar energy but for the most part there are no motors involved.


With passive solar energy systems built into the design of homes and buildings the occupants can save money and also be good stewards of the environment. Solar panels are heavily used in the design of passive solar energy systems to heat buildings as well as water. Passive solar designers look to utilize windows, walls, ceilings and floors to capture sunlight and then redistribute it as energy throughout the building. Many passive solar buildings have large windows facing the south in order to best capture daylight.
