Are you considering investing in sustainable technologies?

Solar energy

Solar panels remain a popular choice thanks to their predictable returns and short payback period. However, even with this technology, there are factors to consider that can make a significant difference to long-term returns.

• Overly optimistic business cases due to energy prices: Many proposals for solar panels are based on the assumption of high energy prices in the future, which has a positive impact on the payback period. However, energy prices are volatile and may also fall, which could have a negative impact on the return on investment. Another aspect is that personal consumption is often overestimated. This is because contractors sometimes carry out simulations without taking into account quarter-hourly values and a correct solar profile.
• Long-term yield guarantees: Many installers offer yield guarantees for 20 years or more. These guarantees often come from manufacturers, but can be difficult to enforce, particularly for smaller parties. If there is a fault, who takes responsibility? Ensure that both the maintenance conditions and the responsibilities are clear.
• System design: For maximum performance, a well-thought-out design tailored to your specific situation is essential. You must take into account not only energy consumption, roof stability and expected energy prices, but also connection capacity and grid connection options. A sound design makes the difference between a good and an excellent return on investment.
• Shade and site analysis: Even a small amount of shade can significantly reduce the output of solar panels. A detailed site analysis, possibly incorporating shade optimisation solutions, is therefore crucial.

Charging infrastructure

Demand for charging points is growing explosively, and companies are investing heavily in charging infrastructure to anticipate the rise in electric vehicles. This offers many opportunities, but a well-thought-out approach is essential.

• Sizing your charging infrastructure: Ensure that the number of charging points and the power capacity match your business’s current and future needs. Too many charging points lead to unnecessary costs, whilst a shortage makes future expansion more expensive. A thorough analysis of charging profiles and growth forecasts helps to identify an efficient, scalable solution.
• Scalability and smart control: Can the system be easily expanded? Smart charging systems, which utilise flexibility in the electricity grid, can deliver a better return by taking advantage of low energy prices and avoiding peak loads.
• Maintenance and safety: A robust maintenance plan and strict safety standards are crucial for reliable performance. Choose a supplier that not only offers solid guarantees but also proactively responds to changing technologies and market conditions.

Battery storage systems

Batteries are becoming increasingly important in the energy market and play a key role in balancing the electricity grid. They offer businesses the opportunity to optimise their own consumption and even generate revenue by participating in flexibility markets.

• Sizing and business case: A battery must be precisely tailored to your energy needs. Is the battery intended to optimise your own consumption, or does it play a role in the energy market? Each scenario requires a different approach, and oversizing can be unnecessarily costly. Furthermore, a precise analysis of the energy profile is essential to prevent you from investing more than is necessary.
• Imbalance revenues and warranties: Earning income from imbalance markets depends on unpredictable factors such as the weather. Some forecasts are overly optimistic, so always ask for a critical evaluation. Furthermore, batteries lose capacity over time, which affects performance. Check the warranty terms carefully and consider the expected degradation over the system’s lifespan.

General considerations

With any investment in sustainable technologies, there are a number of broader factors to bear in mind:

• System integration: How well do the new systems work with your existing infrastructure? An integrated approach can often deliver better results than separate installations.
• Changing regulations and market trends: Sustainability regulations and energy prices are constantly changing. Ensure your investment is future-proof and responds to these developments.
• Quality and references of the installer: Always choose an installer with a proven track record and check their references. A good installation is crucial for achieving the expected results.
