Solar panels are a fantastic investment in the future of your home and our planet. They reduce your energy bill, increase the value of your home, and improve your energy label. But it is precisely this last point that often goes wrong. At Renewable Partners, we regularly see that the documentation for solar panels is incomplete, which means we cannot fully include the panels in the energy label calculation because no quality declaration can be found.
This is not only frustrating for us, but also for the homeowner, who ends up with a lower energy label than the home actually deserves. This can have consequences for the sale value or the mortgage interest rate. So let's take a closer look at what exactly is needed and how it should be done.
An energy label is an official document that shows the energy performance of a home. The calculation is based on the NTA 8800 method, a strict and detailed standard. Every detail of the home, from the insulation value to the installations, is taken into account. Solar panels make an important contribution to a good energy label, but only if the advisor can verify the technical data.
Without the model number of the solar panels, we cannot make a correct and valid recording. Unfortunately, the information below is not sufficient:
To ensure that the solar panels are taken into account for the energy label, it is crucial that the installer provides the correct information. These are the three most important points to consider:
By following these simple steps, we can work together to guarantee an accurate and fair energy label. Let's all make sure that the significant investments in sustainability receive the recognition they deserve!

The difference lies mainly in the degree of insulation and the proportion of sustainably generated energy. An A label can be achieved with good insulation and an efficient installation. For A+++, more is needed: a large proportion of the energy must be generated sustainably, for example with solar panels and a heat pump.
The energy label is determined based on the fossil energy consumption of the home, expressed in kWh/m² per year. For an A label, this value is between 105 and 160 kWh/m² per year. With good insulation, an A label is easily achievable. Homes built after 1991 often already have sufficient basic insulation to fall into this category. Solar panels are therefore not necessarily required to achieve an A label.

I have experienced Renewable Partners as a reliable and professional party in the field of sustainable energy. They think along well, are transparent in their communication, and deliver customized solutions that really meet the need.
Professional and readily available for questions. I am very satisfied with the service and can recommend the company. Kind regards,
While my energy label doesn't matter at all, new residents are going to renovate the entire house, Nik has still made a thorough and clear report of my old farmhouse. TOP job. Thanks
The energy label inspector is a highly skilled professional who knows his trade. We were helped well and quickly with his advice. The reactions of this company are praising the price, the lowest, and the service, downright TOP!
The recording was done carefully. All documents and construction dimensions were checked/recorded by the advisor Ronan van der Loo. And good advice was given. He finished the recording within 2 hours.
