Differences between active and passive solar energy to heat your home

Solar energy has developed enormously all over the world in recent years. If you are considering installing solar energy to heat your home, it is essential that you understand that there are different types of energy that you can use. Most energy can be classified into two different categories, which are active and passive solar energy.

Although both active and passive energy come from the sun, there are big differences between them. If you’re new to the world of solar power, this will probably sound a little confusing, so today we’re talking about the differences between the two.


What is solar energy and why do so many people use it?

Solar energy is energy that can help power our homes, businesses, schools, and more. This energy is obtained from the sun, which then creates electricity. The sun is like a huge generator. The sun sends out its energy in the form of photons, and once the solar panels receive these photons, they can turn them into usable energy.

Solar energy has gained popularity in recent history because it is durable, reusable and environmentally friendly like other energy sources.

The more people use solar energy, the less pollution there will be on our planet. If everyone on Earth took advantage of this energy, fossil fuels and other less clean energies would not be needed.

In recent years, solar technology has seen significant advances, which has made it easier to carry out solar installations in our homes and businesses.

Unfortunately, even with all of these technological advancements, experts still believe that not enough of us are using solar power. Although it is not currently among the sources that provide the most electricity to the system, it is expected to increase significantly in the coming years.

Thanks to the growing popularity, it becomes easier to install and maintain, and it will be much cheaper to buy solar products compared to before. Governments around the world are offering tax incentives and other types of aid to encourage the investment and installation of solar panels.

What is active solar energy?

When we talk about solar energy, we usually mean active solar energy. To use active solar energy, an external power source is required. For example, a support system used in radiators.

Usually people use solar panels, which are usually mounted on the roof of a house.

Active energy uses air or liquid to capture heat from the sun’s rays. It is then moved to the storage container, which is then converted into energy. Liquid is used in most systems. Liquid is considered by most solar panel manufacturers to be better at conducting both power and heat. However, others prefer to use air because it does not freeze during the coldest times of the year. In countries with very cold winters, most active solar panels use liquid.

Whether you use air or liquid, both can provide energy to heat or cool your home.

What is passive solar energy?

Some homes are specifically designed so that passive solar energy can provide energy to heat or cool your home through exposure. Once sunlight reaches your home, the design will be able to reflect, transfer and absorb the sun’s energy. The building materials used to build your home can.

Architects design your home based on predicted air movement caused by the heat of the sun. The goal of experienced architects in this field is:

  • Choose the right material.
  • Put these materials in the right places.
  • Make sure these materials are installed the correct way round.
  • Make assembly efficient.
  • Make it efficient.
  • Helps create natural heating.
  • Help cool the building.

The main difference between passive and active energy is that passive energy has more to do with the design of the building. To create passive energy, you don’t need mechanical or electrical devices, such as fans or pumps, to help move the energy.

How does passive solar heating and cooling work?

The main purpose of a house designed to run on passive energy is to capture and absorb heat from inside the house. When there is no sunshine outside, it is released to keep the temperature inside the house stable.

Most passive energy homes or buildings use thermal mass for heating and south-facing windows.

Passive energy works by cooling a home by reducing the amount of unwanted heat gained throughout the day. It transfers warm indoor air to cooler outdoor air. By storing cool air each night, it helps moderate the temperature of the building throughout the day. The easiest way to improve your home’s temperature is to use tall trees for shade, cross ventilation, and other forms of shade, especially on south-facing windows.

Advantages and disadvantages of using passive solar energy.

The use of passive energy has advantages and disadvantages, such as.


  • Eco-friendly: Most homeowners who choose passive solar tend to use far less fossil fuel, which is great for the environment.
  • Reduce the cost of invoices: Solar energy is free. You don’t have to worry about receiving increases in your bills.
  • Used equipment is not so expensive: Although the price of equipment used for active solar energy has come down, it can still be quite expensive for many of us, the materials needed for passive solar energy are within everyone’s reach. This allows homeowners with a small budget to have an environmentally friendly home.


  • The total cost can be high: Although most of the necessary equipment is less expensive than active solar equipment, upgrading your home to install a passive solar system can be expensive. If your home was not originally designed for a passive solar energy system, you may need to demolish and replace walls and windows, both inside and outside the home.
  • Location, location, location. Unfortunately, you cannot have a passive solar power system in every home due to its location. Just because a system works perfectly in Almeria doesn’t mean it will work well in Madrid. Much research is needed and most people will be compelled to seek the advice of a knowledgeable passive energy professional.
  • May not provide enough power for your home: For those who live in extremely cold regions, passive solar energy might not be able to provide you with enough heat during the winter period. You may need to use another type of energy to help heat the house. The reverse is true in warmer areas, when passive energy generates too much heat, the system struggles to keep the building cool.

With more and more people installing solar panels and introducing new eco-friendly systems into their homes, expect many more people to use solar power to keep their homes warm or cool.
