Green Roofs vs. Solar Panels

Often green roofs and roof-mounted solar panels are seen as mutually exclusive options (either solar panels or a green roof)

OR

SOMETIMES

Our Approach: Triple Green Roof

We offer a solution that combines 3 eco-friendly alternatives that work in synergy:

2. SOLAR PANELS

3. WOODENSTRUCTURE

1. BIODIVERSE GREEN ROOF

Advantages of the Triple Green Roof:No Penetration of the Roof for Mounting Solar Panels

The substrate, drainage and other layers required for the green roof act as a weight to hold in place solar panel modules, which makes it unnecessary to pierce the roof risking to damage the membrane or add extra weight on the roof

Advantages of the Triple Green Roof:Promoting Biodiversity

The addition of an array of PV panels causes shading underneath the panels. It provides a unique habitat for plants and species that require shading.

Research in Switzerland has shown the increased number of species of invertebrates that are able to inhabit a green roof with shaded areas.

Furthermore, water run off from the surface of the panels concentrates moisture allowing for a greater diversity of

Advantages of the Triple Green Roof:Sustainability

Replacing metal with wood in a supportive structure for the solar panels makes our solution particularly sustainable.

Wood has the unique ability to capture and store CO2 while reducing carbon sources.

There are 2 ways to reduce CO2 in the atmosphere:

  reduce emissions or “carbon sources”

  remove CO2 and store it - increasing “carbon sinks”

Wood has the unique ability to do both.

Each cubic meter of wood saves a total of 2 tons of CO2. Every cubic meter of wood used as a substitute for other building materials reduces CO2 emissions by an average of 1,1 ton CO2. If this is added to the 0,9 ton of CO2 stored in wood, we get a total of 2 tons CO2

Even recycled steel production is associated with sizeable amounts of CO2 emissions, while timber required for InnoVentum’s PV support structure reduces CO2 impact

required for cooling or heating of the building. Shading the outer surface of the building envelope has been shown to be more effective than internal insulation.

  In summer, the green roof protects the building from direct solar heat.

  In winter, the green roof minimizes heat loss through added insulation on the roof.

  Energy conservation translates into cost savings and fewer greenhouse gas emissions.

Advantages of the Triple Green Roof:Water Retention

During heavy or continuous rain, runoff can overwhelm stormwater infrastructure and

  Green roof growing media retain rainwater and, together with plants, return a portion of this water to the atmosphere through evapotranspiration.

  Stormwater that does leave the roof is delayed and reduced in volume.

  Stormwater that runs off a green roof is cleaner than runoff from a conventional roof.

  Retention and delay of runoff eases stress on stormwater infrastructure and sewers.

  Cost savings from decentralized stormwater mitigation reduces the need to expand or renovate related infrastructure.

Advantages of the Triple Green Roof:Air Quality Improvement & Reducing Heat Island Effect

Plant leaves trap dust particles from the air (which among other positive effects, helps keep solar panels clean) and evapotranspiration cools ambient temperatures.  Less ground level ozone + less heat = less smog.

Advantages of the Triple Green Roof:Noise Reduction

Based on the numerical simulations and empirical research it was concluded that both extensive and intensive green roofs have the potential to reduce sound pressure levels at shielded places. Replacing a traditional roof by an optimized green roof improves shielding from

For the average listener, such a reduction in sound pressure level corresponds to halving of the loudness.

Micro vs. String InvertersSolar systems are constantly affected by environmental factors, such as shade, dust and debris. Using a traditional string inverter means that everything is wired in series, and the lowest performing module determines the performance of the entire series. This is commonly known as “The

Micro inverters allow each solar panel to operate independently and control the power from each with 99.6%
