How large should PV systems be planned by companies? The answer to this question is actually quite simple: Always as large as possible! This simple principle in the Dimensioning of commercial PV systems naturally applies first of all to solar systems that are Contracting model be realized. But energy-intensive companies with various sites should also use every area, no matter how remote, to generate electricity cheaply and ecologically. Even companies that only operate one site and use the Purchase model prefer must take future developments and changes in their own energy requirements into account when planning their PV system in order to create long-term solutions. Only in this case must careful analyses be carried out in advance to ensure that the investment in a solar system remains economical.
Three fundamental questions arise before planning and dimensioning commercial PV systems:
- Will the solar system be realized as a contracting or purchase system?
- How much electricity does the entire company need?
- Which areas are available and where? (roof, open or parking areas)
Especially with energy-intensive companies With different locations, even a large purchase system can quickly pay for itself economically. Through IEPD™ For example, groups with branches and subsidiaries are no longer restricted to dimensioning PV systems based on the individual electricity consumption of each location. Instead, they have the option, all available areas in an efficient and environmentally friendly way for your own electricity generation. The PV electricity is simply directed to where it is needed.
When dimensioning all other commercial PV systems that are not to be implemented via contracting and are intended for companies with lower energy consumption, many factors must be taken into account. We would like to address these in the following sections.
The importance of efficient and effective dimensioning for commercial PV systems
Efficient and effective dimensioning of all components is crucial to ensure that a commercial PV system functions optimally and achieves the expected energy production. Accurate dimensioning allows the right number of solar modulesthe optimum size of the inverter and other components are selected in order to Maximum energy yield in relation to the investment to be achieved. Incorrect dimensioning can lead to lower energy production, impair the profitability of the system and significantly delay the ROI.
In addition, incorrect dimensioning can also lead to technical problems, such as a Overload or one Overheating of the system. Efficient dimensioning ensures that the PV system is able to supply the required energy and at the same time deliver optimum performance. To ensure that the dimensioning of the PV system meets the specific requirements, we must take all relevant factors into account.
Factors to be considered when dimensioning commercial PV systems
When dimensioning commercial PV systems, we have to take various factors into account in order to achieve efficient and effective dimensioning. In addition to identifying suitable PV areas, an important factor is understanding the load profile and the Energy consumption of the company. This includes analyzing energy consumption over time to determine peak demand and average energy consumption. This information is crucial for determining the optimum system size and selecting the right components.
Another important factor is the selection of the right components for the PV system. This includes the selection of suitable Solar modules, inverters, mounting systems and Cabling. To ensure that each component meets the specific requirements of the PV system and maximizes energy yield, the components must be carefully selected.
The regulatory framework conditions or Feed-in tariffs can influence the profitability of the PV system. A purchase system that is too large may not offer the optimum financial benefit if the remuneration is low or there are limits on the energy fed into the grid.
Another important factor in the dimensioning of commercial PV systems is the evaluation of Shading and alignment problems and the Pollution potential. This can significantly impair the energy production of a PV system. Extreme valley locations, trees, tall buildings, electricity pylons and cables or high dust levels, for example, must always be taken into account during planning and influence the dimensions. The orientation of the solar modules is also important to ensure maximum solar radiation and therefore higher energy production.
Calculation of expected energy production
The next important step in dimensioning PV systems is to calculate the expected energy production. This involves taking into account various factors such as Solar radiationtemperature, tilt angle of the solar modules and efficiency of the components. Precise calculations can be used to estimate the expected energy production, which is important when assessing the economic feasibility of the PV system helps.
Assessment of the economic feasibility of the PV system
Assessing the economic feasibility of a PV system is also a crucial aspect of dimensioning. This includes analyzing the Investment costs, Operating costs, expected Power generation and government incentives such as feed-in tariffs, tax concessions or Subsidies as well as the expected CO₂ reduction and the associated Relief in energy law. A detailed assessment makes it possible to determine the profitability of the PV system and to make well-founded decisions about dimensioning.
Conclusion
The dimensioning of commercial PV systems plays a decisive role in their efficiency and profitability. The principle of planning PV systems as large as possible applies above all to companies in the contracting model or to energy-intensive groups with several sites. Even companies with only one site should take future energy developments into account when planning and not undersize their PV system, provided they have sufficient space available.
Three basic questions must be answered before planning: Purchase or contracting model, total electricity requirements of the company and available space (roof, open or parking areas). Efficient dimensioning is crucial to ensure optimal energy production and profitability. Incorrect dimensioning can lead to lower energy production and technical problems.
When dimensioning, factors such as load profile, energy consumption, suitable areas, selection of the right components, regulatory framework conditions, shading and alignment problems and pollution potential must be taken into account. Calculating the expected energy production, taking into account solar radiation, temperature and efficiency, is another important step.
Economic feasibility is assessed by analyzing investment and operating costs, expected electricity generation, government incentives and environmental impact. A detailed analysis enables well-founded decisions to be made on the dimensioning of commercial PV systems.
