Solar farm repowering and revamping

If you own, manage or run a solar park, or are an owner of a Renewable Obligation Certificate (ROC), you’ll know that maintaining your equipment is critical. But regular maintenance often is focused on simply keeping things running, not on extracting the greatest value and ROI from your system. New advances in PV technology, battery storage and grid connections can all uplift efficiency and availability – sometimes substantially. Not only that, but failing to revamp and update your solar assets puts you at increased risk of technical and operational issues, and your site insurance can easily become invalidated if you fail to correctly maintain your equipment.

Upgrading your solar park through repowering or revamping your system can:

  • Improve asset performance
  • Increase energy production and efficiency
  • Reduce operational and maintenance costs
  • Improve grid connectivity and stability
  • Improve storage and battery capacity
  • Integrate with the latest technology, to ensure your products remain insured and in warranty
  • Increase your PV panels’ lifespan and ROI by as much as 40%

In 2020, more than 67GW of solar capacity turned 20 years old (or older). That’s a lot of equipment that is out of date, out of insurance cover and not performing to its optimal capabilities.

As solar panels and solar farm technology reach their end of warranty or subsidy periods, the most cost-effective option isn’t necessarily a complete replacement, but a consultative approach with solar PV experts, Utilligence, who can advise on the best way to revamp or repower your existing PV system.


Solar repowering for ROC owners

Many early solar and wind farm sites were given Renewable Obligation Certificates, and to keep those sites delivering, choosing to revamp or repower that site can have a considerable financial upside. PV assets need to be in peak condition to operate at maximum production and efficiency, and older and outdated systems are at considerable risk of technical and operational issues, particularly if the ongoing site maintenance isn’t being carried out by solar experts.

Increasing the lifespan of your solar project not only delivers often-drastic improvements in its performance, but also reduces downtime, operational and maintenance costs, saving money in the longer term and ensuring that equipment remains under warranty.

Utilligence is one of the leading experts in renewable energy system design, installation and connectivity. Our team can advise you on whether repowering your solar farm is the best option and the return you can anticipate on that investment.

Should I repower or revamp my solar farm?

Utilligence offers a complete in-house design, engineering, procurement and construction service to help you fully understand the benefits and ROI of any repowering or refurbishment needed for your solar farm. We are fully NERS-accredited and offer complete ICP services for your solar grid connections.

The outcomes from a PV solar revamp or repower could include:

  1. Replacement of any obsolete components, like inverters and PV modules
  2. Improving your grid connection and redistributing the system
  3. Rebalancing of the system
  4. Adding retrofit technologies
  5. Installing new software platforms

 A system revamp returns an ageing solar plant to its original total direct current (DC) capacity, while repowering your system goes further, and improves on your original asset’s capabilities, giving you high output solar panels that can optimise your return on investment.

Why revamp or repower solar PV assets? 

Repowering or revamping a solar park translates into a wide range of benefits. These include:

  • Maintaining performance by replacing worn equipment
  • Reducing or eliminating failure rates
  • Reducing business downtime
  • Increasing the lifespan of your assets, improving your longer-term ROI

As some legacy solar PV companies and manufacturers have left the market, your warranties may be invalid. This can make sourcing parts or making repairs a costly and time-consuming prospect. Replacement parts can be hard to find and making them work with legacy equipment can be challenging. Yet recent advancements make today’s PV solar technology far more efficient than legacy systems, often with a smaller footprint and renewed warranties. It's also considerably more cost-effective, offering long term savings and continued compliance with the latest industry regulations.

Utilligence are experts in renewable energy technology and power connectivity. We have operational solar projects around the world and access to the latest technology and solutions. Our team has decades of experience delivering solar energy projects and can help find the best solution for repowering  your solar farm.
