If you’re like most people, you probably think of greenhouses as being hot, humid places. And while it’s true that they can be pretty warm, there are also several ways to keep them cool. One of the most effective is to use a solar heater. Solar heaters work by collecting sunlight and converting it into heat energy.

Solar Heater For Greenhouse Pros

  • Renewable energy source: Solar heaters for greenhouses utilize sunlight, a clean and abundant energy source readily available in most locations.
  • Reduces energy costs: Solar heaters can significantly reduce or eliminate the need for external energy sources, leading to lower energy bills.
  • Environmentally friendly: Solar heaters produce no greenhouse gas emissions or air pollution, making them an eco-friendly heating option.
  • Low maintenance: Solar heating systems are typically low maintenance, with few moving parts and long lifespans.
  • Energy independence: Using solar heaters allows greenhouse owners to become more energy-independent and less reliant on fossil fuels.
  • Incentives and rebates: Many governments and organizations offer financial incentives or rebates for installing solar heating systems, making them more affordable.
  • Scalability: Solar heaters can be easily scaled up or down to meet the specific heating requirements of a greenhouse, ensuring optimal temperatures for plant growth.

Solar Heater For Greenhouse Cons

  • High initial investment: Solar heaters often require a significant upfront investment, which can be a barrier for some greenhouse owners.
  • Intermittent energy source: Solar energy is only available when the sun is shining, which means a backup heating system or energy storage solution is needed for cloudy days and nighttime.
  • Space requirements: Installing solar panels or collectors may require additional space, which can challenge more miniature or densely packed greenhouses.
  • Installation complexity: Properly installing a solar heating system can be complex, often requiring professional assistance.
  • Regional limitations: Solar heaters may be less effective in regions with limited sunlight or long periods of overcast weather.
  • Aesthetic considerations: Some greenhouse owners may find solar panels or collectors unsightly, which could impact the overall appearance of the greenhouse.
  • Efficiency loss: Solar heaters may lose some efficiency over time due to panel degradation or dirt accumulation, requiring periodic maintenance to maintain optimal performance.

This heat is then transferred to the air inside the greenhouse, raising the temperature. Solar heaters are an environmentally friendly way to heat a greenhouse and can also be very cost-effective. If you’re looking for a way to keep your conservatory cool, consider using a solar heater.

If you are planning to install a solar heater in your greenhouse, the first goal you need to consider is efficiency. You will need the correct quantity and quality of panels for the greenhouse.

You will also need enough panels to cover the total heating demand of the greenhouse. If you are considering using a solar heater for a greenhouse for residential use, you need to choose the location close to your residence, ideally near your greenhouse. Though you can still use cheaper and non-premium panels, higher efficiency panels are best for integration.

Passive Solar

A passive solar greenhouse is a low-tech alternative to a traditional greenhouse. Because it does not require heating, the greenhouse retains heat during the day and keeps cold nighttime temperatures outside. You must install proper glazing, insulation, and methods for capturing solar energy to make your greenhouse passive. You can build one today if you do not have a greenhouse yet.

You can make a passive solar greenhouse for less than half the price of a traditional greenhouse.

A passive solar greenhouse can be a solar heat collector during winter if you live in an area with very little sunshine. You can also install exceptional curtains to keep the greenhouse warm at night. These curtains can be lowered from inside and outside the greenhouse. They can also be monitored and operated automatically. You can use these curtains with electric heat to reduce your greenhouse heating costs. The passive solar greenhouse is an alternative heating solution for any greenhouse.

Heat Exchanger

Installing a greenhouse heat exchanger for a solar heater can have several advantages. It doesn’t require professional installation and is incredibly inexpensive. Because greenhouse heat is derived from the sun, the system is not only good for the planet but also for your wallet!

However, you must have electricity to power the fan and solar panel to provide sufficient heat exchange. Solar panels are an excellent choice if you’d like to avoid having to purchase electricity for the heat exchanger.

While you can buy photovoltaic solar panels, these units are not very efficient at heating a greenhouse. They require a large surface area and can be pretty expensive.

Heat exchangers are a great alternative to photovoltaic systems, as they don’t need professional installation and can be installed without specialized knowledge. Heat exchangers help distribute heat evenly. However, they are less effective than hydronic heaters because they use a fan instead of a boiler to create heat. They can also be inefficient in cloudy weather.

Cadmium Telluride

If you are looking for an energy-efficient way to heat your greenhouse, consider using a Cadmium Telluride solar heater. This type of solar panel can be easily made from large single sheets.

Although they may cost a bit more than traditional solar panels, they are relatively cheap. They can even be made in bulk to reduce the cost. And, unlike their solar panel counterparts, they are essentially maintenance-free.

The benefits of a cadmium telluride solar heater for the greenhouse are numerous. This substance is a stable crystalline compound consisting of cadmium and tellurium. It is a semiconductor material that traps sunlight and is often used to make infrared optical windows and photovoltaic cells.

However, it is not a perfect solution for greenhouse solar heating. For this reason, it is essential to perform a comprehensive assessment of its environmental and cost-effectiveness.


The Nakoair solar heater for a greenhouse is designed to provide heating and air purification at no cost. This system can switch between solar and electrical energy. Its low voltage eliminates dust and household electricity and is energy efficient and environmentally friendly.

The multi-layer sheet laminations also protect the solar panel, allowing it to work even in overcast weather. The charging regulator keeps the unit functioning at optimum levels.

The Nakoair solar heater for greenhouses provides temperature control, saving energy while heating the greenhouse. The unit’s high-quality heating efficiency makes it a perfect choice for greenhouses.

The 10W solar panel uses just 10 kWh per year. The Nakoair solar heater is CE-certified and has passed European standards. For more information, visit the Nakoair website. Once you purchase your solar heater, you’ll know it will work efficiently.

Solar Water Heater


A solar heater is a device that uses energy from the sun to heat something. There are many solar heaters, but the most common is a panel that converts sunlight into electricity. Solar heaters can heat water or air, which is a great way to reduce greenhouse gas emissions. Some solar heaters also provide air purification.
