Photovoltaic systems optimisation

Maximise the yield of your photovoltaic system and increase your return on investment

Utilising potential
for maximum

There is often unused optimisation potential. Our service team uncovers this and increases the energy yield of your photovoltaic system in the long term.

Utilize potential and optimize PV plant

System optimisation is of great importance for solar system owners who want to make their energy system more efficient. Targeted measures to increase self-consumption can not only reduce electricity costs from the grid, but also achieve considerable savings. An effective energy management system makes it possible to optimise the use of the solar power generated, store surpluses or feed them into the public grid.

Our team offers a wide range of services in the field of system optimisation. We analyse existing solar systems to identify weak points and highlight optimisation potential

Regardless of whether your PV system was built by SENS or not: we take over the system optimisation and look for an individual solution from the various options available. This allows you to make optimum use of the sun's energy and benefit from numerous advantages. 

We also advise you on the selection and installation of new photovoltaic systems that are designed for maximum efficiency and profitability from the outset. 


Optimising solar energy systems offers both economic and ecological benefits. It is advisable to carry out regular inspections and maintenance to ensure that the solar system is operated efficiently and its full potential is utilised. 


  • Increasing energy efficiency: By optimising a solar installation, more solar energy can be converted into electricity, resulting in a higher overall output of the PV system.
  • Maximising electricity generation: System optimisation can reduce mismatch losses and implement Maximum Power Point Tracking (MPPT) per module. 
  • Cost savings: By utilising solar energy efficiently, self-consumption can be increased, reducing the need to purchase expensive grid electricity.
  • Long-term profitability: By increasing power generation and reducing operating costs, a better return on investment can be achieved.

Green cuttings for yield optimisation

It is not only good maintenance and regular cleaning that are important for the optimum operation of a solar installation. The green area under the PV modules also needs to be looked after. Otherwise, grasses and wild shrubs can shade the PV system and lead to losses in electricity yield. 

However, green maintenance is not always easy: some areas of the solar park are difficult to access. Operators therefore often rely on mechanical green pruning by specialised service providers. Sheep grazing is also an ecological alternative - sustainable and cost-efficient.

5 steps to maximise the electricity production of your solar system 


As a full-service PV service provider, SENS takes care of optimising your system. Regardless of whether it was built by SENS: we also carry out system optimisation for third-party systems. 

The path to a system with maximum yield involves five steps:

Step 1: Assessing the condition of the system 

We carry out a thorough inspection of the PV system to assess its current condition. As soon as we include a third-party system in the service, we check and evaluate its performance based on the available data. This includes checking the photovoltaic modules, inverters, cabling and mounting systems. 

Step 2: Recommendations for action

Based on the inventory, we make recommendations for action to maximise your yields. These may include repairs, maintenance work or upgrades to improve the performance and reliability of the system.

Step 3: Economic viability test

It goes without saying that optimising your system should be economically feasible. We will be happy to calculate the profitability of various investment options for you. Factors such as electricity generation, feed-in tariffs, operating costs and financing options are taken into account.

Step 4: Implementing the measure

We do the work for you and support you in implementing successful optimisation measures. This includes, for example, refitting and repowering measures, whereby components of the photovoltaic system are modernised or replaced.

Step 5: Final effectiveness test

Once the recommended measures have been implemented, we check the effectiveness of the corresponding measures so that you have proof of their success. This includes a re-evaluation of the performance and efficiency of the solar system to ensure that the desired goals have been achieved.

Contact us with your optimisation requirements and we will be happy to advise you.

Refitting and repowering of solar systems

The advantages of refitting and repowering measures speak for themselves: increased energy production, long-term system availability and lower service costs. The optimisation measures can relate to the various components of a solar system: PV modules, inverters, storage systems, etc.

Our case studies show the positive effect this can have on the performance of your photovoltaic system.
