***General Introduction***
This dataset is based on a full-scale research performed on two adjacent apartment buildings in Amsterdam. 
One roof has a bitumen surface with a solar PV system, the other is a blue-green capillary irrigated solar roof with 
grey (shower-) water suppletion, with a constructed wetroof for grey water purification. 
In the research, the solar output of both roofs was measured and compared, including temperature, irradiation and humidity measurements.
 
The dataset is being made public to act as supplementary data for publication(s) and the PhD thesis of Els van der Roest. 
Also, it might be used by other researchers.

This dataset is a result of the TKI project Urban Photosynthesis and is co-financed with PPS funding
from the Topconsortia for Knowledge & Innovation (TKI’s) of the Ministry of Economic Affairs and Climate. 

***Description of the data in this data set***
This dataset contains the data from 2x6 solar panels on two adjacent apartment buildings in Amsterdam. 
On each roof (blue green - BG) and bitumen (Bi), the energy output and back of panel temperature of 6 panels was measured.
Furthermore temperature and relative humidity were measured under 3 panels on each roof, as well as the temperature 
of the roof surface in the shadow of the panels.
On both roofs the temperature, relative humidity and irradiation were measured above the panels (1.5 m height).
Lastly, 2 temperature sensors were placed in the soil of the blue-green roof, and a rain meter was installed.

The dataset covers 5 months, June to October 2022, and includes only day data (hours with solar irradiation).
