FAQ

Does the energy delivered by a PV module throughout its lifespan counterweigh the energy used to produce it?

Relevant progress has been made with regards to the Energy Pay-Back Time. The time required for the PV module to work off its energy debt is 1 year. Considering a lifespan of 30 years, a PV module will produce around 30 times the amount of energy that was required to build it.

Can the PV modules be recycled?

94%, that’s the average reuse rate for crystalline PV modules with an aluminium frame!

Can the waterproofing works cause constraints on a solar roof project.

Yes. It is necessary to consider and design the future installation of a power station while erecting the building. It is not only true for solar systems but also for numerous work contract lots. Naturally, these works are subjected to insurance requirements and must comply with up-to-date regulations.

What’s the current dynamic with regards to solar electricity production cost?

The cost of solar electricity production continues to decrease. According to a report from the International Renewable Energy Agency (IRENA), it could even decrease by another 60% by 2025.

What is your standpoint on existing waterproofing systems with no need for refurbishment?

Our technical requirements provide for the implementation of a new SOPREMA’s waterproofing system. For existing building, it is worth understanding the complete buildup starting from the decking by analyzing the As-Built Documentation. If you have any questions, don’t hesitate to contact our Sales Managers.

On a PV-ready roof, what is the number of PV modules that can be installed?

It depends on several factors. To provide the best answer, we need to assess if panels can be installed across the entire roof and identify any hindrances or amenities present. Generally, the ratio is 1 kWp per 10 sqm. Please feel free to contact our Sales Managers for more information.
