Industrial Photovoltaics

and the public sector

If a company needs to reduce its electricity costs and has available space on rooftops or within its property, the ideal solution would be to install a photovoltaic (PV) system. Photovoltaic panels convert solar energy into electrical energy. Such a panel generates direct current, which is then converted into alternating current using an inverter, making it compatible with the parameters of the electrical grid.

There are two basic types of photovoltaic panels: monocrystalline panels and polycrystalline panels. Monocrystalline panels are currently the best option due to their highest efficiency, which ranges from 15% to 19%. The second type is polycrystalline panels, which have lower efficiency (14% to 16%) and, as a result, you would need more of them to achieve the same efficiency as monocrystalline panels.

The most important factors ensuring the most efficient operation of the installation include:

1. Choosing the appropriate power capacity of the installation for the company’s business profile

The power capacity of the PV installation can be considered optimal if it ensures the maximum utilization of the generated electricity for self-consumption (while minimizing the sale of surplus electricity to the grid) while achieving a maximum self-sufficiency ratio.

To achieve this, it is necessary to conduct an analysis of energy efficiency (taking into account the hourly profile of electricity consumption and production from the photovoltaic installation) as well as the financial efficiency of the energy system with the PV installation.

Only in this way can we correctly determine the parameters of the photovoltaic installation and the installation method and avoid overestimating and oversizing the installation. Conducting analyses based on invoices or even measuring electricity consumption for a period shorter than the base year is worth as much as… the paper on which it is described.

2. Optimal selection of panels and their placement on the roof or on the ground

In order to make the most efficient use of electrical energy from a photovoltaic installation, special attention should be paid to its proper installation. The installation should be mounted taking into account all factors affecting its efficiency, such as the distribution of sunlight during the day and year, consideration of potential shading zones, cardinal directions, as well as the type and inclination of the roof. The selection of the installation is preceded by thorough calculations and the creation of a project.

What does the use of an optimal photovoltaic installation based on our analysis provide?

• It ensures the highest coverage of electricity demand from renewable sources (RES);
• The unit cost of obtaining electricity from PV is the lowest for an optimal installation;
• An optimal PV installation has the shortest Simple Payback Period (SPBT);
• It reduces the power fee and partially reduces the costs incurred for exceeding the contracted power.

At Energy Trend, we help objectively select the optimal parameters for photovoltaics and the most efficient solution and installation method for PV systems. We provide comprehensive support for investment implementation and securing funds for it.

Photovoltaics for industry enables the production of electricity using solar energy. The greatest advantage of such a solution is that solar energy is free. Another important benefit is partial independence from energy suppliers and the risk of rising prices or power supply interruptions. Some people may be concerned that the level of sunlight in Poland may not be sufficient for the proper functioning of photovoltaics, but Poland is actually a very good location for installing photovoltaic systems. The temperature in southern Europe often exceeds 25°C, which negatively affects the efficiency of photovoltaic cells. Even higher temperatures persisting for extended periods can be detrimental to these cells. Thanks to appropriately designed energy storage systems, surplus electricity produced can be stored and used during cloudy days.

Industrial photovoltaics enable significant cost savings for businesses and are easy to manage. They do not emit harmful substances, including carbon dioxide, making them environmentally friendly. Before installing a photovoltaic system, it is recommended to conduct an energy audit. To finance the investment, business owners can take advantage of various types of grants and favorable loans.
