6 FAQs about [Fine for delayed work of photovoltaic panels]

What happens if a solar project is delayed?

Previously, delayed completion could cause a solar project to become unviable due to a failure to achieve accreditation for incentive payments. In early large-scale solar projects, this failure could result in the contractor having to remove all plant and equipment and reinstate the site at its own cost.

What are the construction issues relating to solar PV installations?

The key issue for solar developments is visual impact and glare. For those looking at procuring their own systems, it is worth briefly touching on some of the construction issues that relate to solar PV installations. One of the key issues is whether the roof can handle the weight of the solar panels.

What happens if a solar EPC contractor fails to complete a project?

Solar EPC contracts generally provide fixed dates for project completion. If the contractor fails to complete on time, it will often be liable for liquidated damages (LDs), unless it is entitled to claim an extension of time to the completion date, thereby reducing or avoiding liability for LDs.

Do solar plant projects have performance issues?

While parties to solar plant projects will try to deliver complete and functioning assets, performance issues and disputes will invariably arise from time to time. Some common examples we see include issues relating to: Internal corrosion due to water ingress.

Is the UK solar PV sector moving fast?

The UK solar PV sector is moving fast and it is a challenge to keep on top of market practice in FIT contract arrangements and the changing regulatory position.

How long do solar panels last?

Once the plant has been commissioned, the tariff applying to it at the commissioning and accreditation date is the one that it will have for the life of the plant (25 years) so there is a tremendous incentive to fit these panels while taking advantage of the high rates available.
