Installing solar panels on your company's roof offers many advantages. For one, you are actively working on sustainable business practices and preparing for a future with only renewable energy. In addition, it is also financially attractive. Because the price per solar panel is getting lower and lower, using solar energy is also becoming more accessible.
There are also attractive subsidy schemes in the Netherlands, which can create a favorable business case. An additional advantage for installing solar panels on your roof is that it is not necessary to apply for an environmental permit. This is because the solar panels actually become part of the building. There are a number of exceptions. For example, if your building is designated as a monument or if the building is in a protected city or villagescape.
If you have any questions about this, please contact your municipality, or call us and we will find out for you.
If you plan to have solar panels installed on the roof of your business, there are a number of things that need to be taken care of.
At Ekwadraat, we divide this process into 8 steps. With this roadmap you can be sure that you will realize a successful project.
The steps are as follows:
Not every roof is suitable for solar panels. There are a number of aspects that determine the suitability of your roof:
The ideal orientation of your roof is to the south. If your roof is not facing south, this does not immediately mean that it is not interesting for you to have solar panels installed. The size and shape of the roof determines how much energy can ultimately be generated. In many cases, a larger surface area means a more favorable business case.
In addition, the available roof area must be large enough to accommodate at least 15 kW of installed power. When converted to surface area, this results in a minimum roof area of 200 m². The grid connection must be at least 3 x 80 amps to receive the SDE subsidy.
To further help determine if your roof and grid connection are suitable, please see our page on feasibility solar panels.
The SDE++ subsidy can be applied for various forms of renewable energy, including solar energy.
If the grid connection and the available roof area are sufficiently large, you can receive subsidy on the energy generated.
The SDE subsidy works as follows: first, you indicate how much subsidy you want to receive per kWh generated. The SDE subsidy then works like an auction system: the cheapest projects (per kWh) are the first to go and only the projects with the most expensive compensation come last. In recent years, the SDE budget has been exceeded several times. This means that too expensive projects often did not receive a subsidy. It is therefore important to deploy strategically.
After the SDE subsidy decision has been received, it is wise to draw up a Schedule of Requirements (PoR). In it you include all the information relating to technical and quality requirements. You indicate what the installation and the supplier must meet. Based on the PoR, you can request quotations from different suppliers.
You can assess the quotation very well using the PvE. At Ekwadraat we use a system based on the PvE with which we can categorize suppliers based on their sustainability for your project. By using a PvE you can select the most fitting supplier to realize your project.
Getting the financing needed for your project will be relatively swift once you have an SDE++ acquirement, since you will get 15 years of subsidy on your produced energy. A business case can be made based on the supplier and installation you chose. You can use this business case for possible acquirement of financing from, for instance, a bank.
We advise you to check if the right components are being used and that agreements are followed during construction, which have been defined in the PvE and contract.
After delivery, you want to be sure that the installation functions properly. It is therefore a good idea to check it immediately after delivery. At Ekwadraat we use a delivery protocol based on the NTA 8130. This way you can be sure that the installation is performing properly.
Then you should not forget to register the installation at CertiQ, so that the SDE+ subsidy can be paid out.
The final step is to check that the subsidy is actually paid. You can check this at CertiQ. Finally, we ourselves always do a check after a month to see if all systems are functioning properly.
