BIPV pricing in the Netherlands : 2014 Price benchmark report
report
In this benchmark we investigated the price levels of the Building Integrated Photo-Voltaics (BIPV) market in the Netherlands. There is a broad scope of different BIPV applications (e.g. roofing, façades, skylights, glazing, etc.). This study limited itself to the applications for pitched roofing in the Dutch residential sector. Two types of BIPV applications (tiles, in-roof systems) were compared to conventional roofing and conventional Building-Attached Photo-Voltaic (BAPV) roofing solutions. Suppliers of BIPV systems were invited to quote on a virtual home with the target to make the house net electricity zero. Two virtual homes were defined. The first virtual home was a terraced house with 60 m2 roof area and 3300 kWh/a electricity usage. The second virtual home was a detached house with 125 m2 of roof area and 4600 kWh/a electricity usage. The quotes were split up in various categories including electrical connection costs (cables, inverter, AC connection), PV installation costs, PV fastening system costs, PV panels costs, Installation costs, and conventional roofing materials costs. In total, 11 quotes for BIPV systems were received. These were well-distributed over the two categories of BIPV in-roof systems and BIPV tiles. In addition, 8 quotes on conventional BAPV systems were gathered for price comparison. It was chosen to report the turn-key prices for the full roof upgrade rather than the common unit of €/Wp, because only in this way a clean comparison between the various solutions to make the house net electricity neutral could be made. From the analysis of the prices, the following key conclusions can be drawn:
- Turn-key prices for retrofitting a BAPV system and make the house net electricity neutral are €6,000 for a terraced and €8,000 for a detached house. BIPV in-roof mounting systems add €2,500 to these costs, due to three main effects:
o Additional labour is required due to the removal of the existing roof tiles.
o Suppliers of BIPV in-roof mounting systems tend to choose high quality European brand PV panels in their systems, whereas BAPV system suppliers tend to choose low-cost Asian brand PV panels.
o More costs are made in the installation process, due to a more complicated and slower installation process than BAPV systems.
- Turn-key prices for renovating a full roof and then adding a BAPV system to make the house net electricity neutral are €10,000 for a terraced and €16,000 for a detached house. BIPV in-roof mounting systems add €1,000 to these costs. Cost savings are made for requiring less roof tiles, but additional expenses are needed for the use of more expensive high quality brand PV panels and longer installation times required.
- Several suppliers of BIPV tiles are active on the Dutch market. Their products are meant to blend better into the roof’s optical appearance and consequently improve the overall aesthetical quality of the house. A large price spread within the products that are offered exists. The cheapest BIPV tile solution for a turn-key roof renovation was €14,000 euro for a terraced and €21,000 euro for a detached house. The most expensive solution was €23,000 euro for a terraced and €35,000 euro for a detached house. The large price range suggests a proto niche market or sub-segmentation within this product group.
- Comparing the dwelling types with each other we see an overall price advantage in favour for larger roof systems. The electricity producing roof on a detached house was approx. 20% cheaper per m2 than the same system on a terraced house, for all three system types of BAPV, BIPV in-roof systems and BIPV tiles.
