business case - onze werkwijze-3

As soon as we receive an application, we start developing a business case for your company. We compare different commercial models for your real estate. This way, you can be sure that you will get the most out of it.

SDE++ subsidy for solar roofs

A subsidy is available for solar panels. If this is interesting for your business case, we can apply for a subsidy on your behalf. This will save you time and complicated procedures as we have standardised the process.

SDE (Dutch for Stimulering Duurzame Energieproductie) translates to Stimulation of Sustainable Energy Production. With this subsidy, the Dutch government incentivizes the production of renewable energy, such as solar panels. Thanks to this subsidy, entrepreneurs and organisations are able to produce their own clean energy and emit less CO₂.

The SDE++ subsidy makes the realisation of a solar power plant on your company roof or site investment worthy. It greatly enhances the cost-benefit analysis of an investment in solar panels.

Stage 2: Technical study

There is much involved in creating a solar roof on your business premises. Our experts investigate all technical and commercial aspects beforehand so that you are not faced with any surprises. We develop this into a programme of requirements.

Archive research


Structural research


Assessment of roofing construction and roof structure

Stage 5: Asset management

Do you want to better understand your solar roof once it's operational? Then the last step is asset management. This provides deep insight and analytics into the performance of your installation. Track the production and sustainability of your solar roof and take care of financial, legal and regulatory administration. We also keep an eye on technological upgrades.

Research shows that these tasks are often overlooked in the strategy and long term planning of solar projects, leading to loss of revenues and long-term operational problems. We offer a solution for our customers to avoid mistakes from the start. This way, you maximize your solar power system.
