For a medium-sized solar factory requiring a connection of around 5 MW, costs can range from 200,000 to 500,000 euros. This figure can vary substantially based on the factory's distance from existing grid infrastructure and the complexity of the required upgrades. Understanding the nuances of grid integration and energy cost management from the outset is not merely a technical detail;. . In addition to the price of solar panels and inverters, the installation environment has a significant impact on the cost of the project. Grid connection is also an important cost. . Finland is one of the few countries where solar power, in many cases, does not receive any subsidies, although companies and communities may apply for energy aid for smaller-scale (<5 MW) solar PV projects, which covers 15 % of the investment costs. In practice, an electricity bill has three main parts: energy, network (transmission/distribution), and taxes, all of which are. .
