The subsidy scheme for solar water heaters was 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.
A new support scheme is the SDE+. This is a feed-inn tariff that has been expanded to include large (>100 m2) solar heating systems. The feed-inn tariff works with a tender system. The tariff is between €0,- and €20,- per Gj produced useful heat.
For solar building the main incentive is the building regulation and local climate policies.
For quality control the solar keymark is well accepted and the Dutch equivalent (Zonnekeur). For the quality of the installation work a system will be set-up as part of the requirements of the renewable energy directive from the EU.
