The key difference here is that passive systems make use of no moving parts, electronics, or other controls. Instead, they rely solely upon the natural absorption of solar radiation in thermal mass.
What is active solar heating?
When we use the term ‘active’ we mean any system that makes use of moving parts, electronic controls, or other intelligent systems.
How does solar energy work?
Active solar energy systems work by heating either a liquid or a fluid inside a solar collector. This heat energy can then be transferred to water in a heat exchanger (if using fluids) or blown into a building (if using air). Both of these options help to heat a home. Active solar energy systems use collectors like this one.
Why do solar panels have south facing windows?
They make use of large south-facing windows to allow solar radiation into the building. Once solar radiation enters a passive building, it can be absorbed by thermal mass which retains heat. Over time, the building will release this energy, helping to keep the building warm.

Passive solar systems simply use sunlight directly, without any additional motors, inverters, or other equipment to ‘process’ that sunlight into something else. Typically, this means using the sun’s heat to warm buildings on cold days – a very common ‘green’ building design principle.
What does active solar mean?
If you can remember one thing, just remember that ‘active solar’ means processing the sunlight or using that sunlight indirectly in some way. That could mean turning the sunlight into electricity or using sunlight to heat water indirectly, either for personal use or even to create electricity.
What are thermal solar panels?
They were actually thermal solar panels, which harness the sunlight’s heat to preheat water for home use. Even now, driving throughout the west, you’ll see old thermal solar panels dotting roofs, either pumping away hot water or rusting away as a reminder of those times. Okay, enough of a history lesson.
Why are solar panels installed on roofs?
All over the country, people are installing solar panels on their roofs to produce their own electricity and save some cash. In fact, residential solar grew about 1,250% from 2010 to 2016 – talk about an explosion! But this wasn’t the first solar explosion. 40 years ago, there was a huge explosion in solar as well.

Remember, passive solar simply means that the sun’s heat or light isn’t ‘ processed’ into something else.
Can solar energy produce electricity?
Yes, there are huge power plants out there that create electricity with thermal solar! For example, a technique known as concentrating solar thermal uses huge mirrors to superheat antifreeze running through tubes. That antifreeze then passes through a heat exchanger to heat up water and produce steam.
Passive VS Active Solar Energy: What Is The Difference?
The sun is the closest energy source for life on Earth. It was present for 4.5 billion years and it is expected to shine for at least another 5 billion years. It is not surprising that most people have a positive association with the sun. The sun is the symbol of life, creativity, and happiness.
Types
There are a few types of passive solar energy. The first is called direct gain, which is the simplest type of passive solar energy. This type of passive solar energy warms a house with the heat of the sun’s rays moving directly through a window. The second type is called indirect gain.
History
The process of heating a house with passive solar energy has been around for thousands of years. The first use of passive solar design is thought to have occurred in 4000 B.C. in Egypt [3]. In those times, the sun’s rays were used to heat the inside of homes.
Heating
