Status of Solar Heating/Cooling and Solar Buildings - 2016

Status of the Market for Solar Thermal Systems

Market Size and Trends

The market in the Netherlands for solar water heaters has been stable, but small, since the subsidy scheme ended in 2011. The main market is domestic hot water systems. Systems for space heating are in general too large for the small houses in the Netherlands, but the interest for these systems is growing. The market was focused on new houses, but as there is less housing development, the focus has shifted to existing houses.

Since last year the construction of new buildings is increasing. However, despite requirements for the buildings to be very energy-efficient, solar thermal systems are rarely used. In most cases builders integrate PV-systems in their buildings. In 2016, a new subsidy scheme was introduced (the ISDE-subsidy). This has increased the market.

Typical Applications and Products

The main application is domestic hot water. The systems are mainly pumped systems with still a lot of drain back systems, but the number of pumped systems with glycol is increasing due to imports from other countries. The systems are in general about 3 m2 with a 100 l tank. Larger systems are used for agricultural, for example in dairy farms for cleaning. Another development is the solar thermal roof. This is an uncovered collector that is integrated in the roof of a building. The application is the regeneration of aquifer thermal storages of borehole storages. Recently many of these systems are combined with PV in PV-thermal systems.

Main Market Drivers

The main market driver is the building regulation for new buildings. The regulation requires a certain performance level and solar water heaters help to reach the requirement. There is a lot of competition from other technologies like PV. For existing buildings there is an energy label, but there are no demands to the required performance. Most installers are still not very active in selling solar water heaters. Hot water is mostly produced with efficient gas boilers and gas is cheap. It is therefore difficult for solar water heaters to be cost competitive. The main sales in existing buildings is with owners who specifically chose a solar water heater for environmental reasons.

Large systems (> 200 m2) can benefit from a feed-in tariff from the SDE+ scheme, but this has had little effect up to now. In 2016 several large projects were proposed for heating greenhouses.


There is a domestic manufacturing base, but it has decreased over the last years. After the subsidy stopped in 2011 many manufacturers decreased their production. The growth now comes mainly from newcomers who import systems from Europe or China. The few manufacturers are coming out with innovative solutions, such as a polymer tank and a collector the size of a PV-panel.


Estimates from the trade association Holland Solar range from to 300 to 500 jobs (full time equivalent) in the Netherlands for the solar thermal industry, including installation and related service (testing, etc.).


A solar water heating system costs around €2,500 for a 3 m2 system installed (including VAT). Prices vary considerably depending on the project size, system type and ease of installation.

Other Key Topics

There is a quality certificate for installers (zonnekeur). This is developed both for solar thermal and PV installers.

Status of the Market for Solar Buildings


The focus in the Netherlands is on low-energy buildings and energy neutral buildings. Active and passive solar technologies and daylighting are included in the rating system. There is no separate focus on solar buildings. For new buildings the aim is that all new buildings should be near-zero by 2020. For existing buildings there is a big project called Transition Zero that targets high level renovations to come to net zero in existing houses.

Market Size and Trends

The interest in space heating with solar is growing. Also combinations of solar heating and heat pumps are growing, but there are still a lot of different configurations in use. Daylighting and daylight control is popular. Most modern enery efficient offices have daylighting control. There is an active community simulating the use of daylight: .

Starting in 2020 all new Dutch houses are to be build almost energy neutral. It's difficult tot predict the amount of new houses per year, but last year (2015) about 50.000 new houses were build. It's likely that from 2020 on a structural part of this amount is going to be equiped with solar thermal systems.

Main Market Drivers

There are two main drivers for low energy buildings. the first one is the aim to make new building near zero energy buildings by 2020. Many players are already developing concepts for these types of buildings. The second one is the movement "Transition zero" mentioned above. The aim of this movement is to make about half a million existing houses energy neutral using industrial methods. As of now, a couple hundred so called prototypes have been made. Allmost all of them are equiped with PV systems. Thermal systems are rearly used.

R&D Activities

R&D Programmes

There is no national R&D program for solar thermal energy. The program for renewable energy at does include a few activities for solar thermal energy.

The research work for heat storage is funded through projects in the top sector energy. Also work on integrated energy solutions and smart buildings can get funding.

Actual Innovations

The Netherlands developed the drain-back technology for solar water heaters. For heat storage the focus is now on chemical storage technology.

Support Framework


The goal for renewable energy is set at 14% in 2020 with the EU and there is a national energy agreement that aims at 16% renewable energy in 2023, see There are no official goals for solar heating. The trade organisation, Holland Solar,  has made a plan to accelerate the market.

Government Agencies Responsible for Solar Thermal, for Solar Building Activities

The main agency is the Netherlands Enterprise Agency (formally named AgentschapNL and SenterNovem).

Most Important Public Support Measure(s) for Solar Thermal and for Solar Buildings

The subsidy scheme for solar water heaters ended in February 2011. Commercial businesses can still benefit from the tax-reduction for energy investments (EIA), which comes to about 15% of the investment costs.

The ISDE support scheme was introduced in 2016. It is an investment subsidy. The subsidy level is based on the output according to the documentation of the European Energy Labelling system. The investment subsidy is €0,50 per yearly kwh produced for systems up to 10 m2. This is about €600 for an average system.

A new support scheme is the SDE+. This is a feed-in tariff that has been expanded to include large (>200 m2) solar heating systems. The feed-in tariff works using a tender system. The tariff is between €0 and €0.08 per kwh produced useful heat.

For solar buildings, the main incentive is the building regulation and local climate policies.
