Subsidies for photovoltaics 2025: Current overview for companies and public organizations

‍

Each new round of subsidy titles changes a bit. Ministries adjust terms, Amount of aid in administrative complexity so that the challenges better correspond to the current market development, Technological possibilities in the needs of the applicants. 2025 is no exception. It introduces several key changes that can decide whether you will be successful in applying for a subsidy. It is worth paying attention to them already at the preparatory stage, even if you have applied for a subsidy in the past.

‍

‍

‍

‍

Best suited for small and medium-sized companiesthat want their own solar power plant for their consumption. They can also apply for subsidies. large enterprises. Emphasis is placed on own use of electricity, buy-in to the network is limited. This subsidy program offers simple administration and faster return on investment. The subsidy can also be for photovoltaics project associated with accumulation.

‍

‍

‍

Pro large companies and industrial sitesthat want to build bigger solar parks. The challenge is in preparationIt is worth watching, because it will be a big deal. subsidy for photovoltaics for companies.

‍

‍

Aiming at Smaller municipalitiesthat want to install FVE on their buildings. An interesting combination of high support (60%) and the possibility to include project preparation, roof renovation and energy management. Also suitable for those who are starting out with renewable sources. The subsidy may also be for a photovoltaic accumulation project.

‍

‍

Challenge for counties, cities and contributory organizations. It enables the implementation of larger projects, including accumulation and renovation of roofs (only if without reconstruction photovoltaics cannot be installed). Higher administration, but also comprehensive project support with higher impact.

‍

‍

New in 2025 — The challenge is focused on securing Accumulative flexibility of the electricity system (balancing the balance between production and consumption, deviation management, provision of regulatory energy, etc.) Designed for companies and the public sector that already have or are installing PV and want to expand with Accumulation (AKU).

‍

Do you want to get a quick overview of how much a photovoltaic power plant will cost you and how long it will take to pay back your investment? We have prepared a simple calculator that will help you estimate the price and return. Just select type of entity, choose FVE size to enter estimate your electricity price. The calculation is indicative, but it will help you evaluate the basic the economics of your project in a matter of seconds.

‍

Subsidies for photovoltaic power plants and accumulation It's not just for big players. Both companies that want to reduce energy costs and cities and municipalities looking for ways to upgrade public buildings and better manage their budgets can apply.

‍

Private sector

‍

This category includes companies, entrepreneurs and other commercial entities that want to invest in their own energy production. Subsidies are intended for:

‍

• Legal and natural persons doing business in the energy sector
• Existing or future licensees for electricity generation
• Also Applicants without a licenseif they demonstrate that the operation of the power plant is contracted by another licensed entity

‍

Public sector

‍

Public bodies have increasing opportunities in the field of photovoltaics, in particular through the support of energy communities and the renovation of public buildings. Eligible applicants include:

‍

• Municipalities, cities, regions, urban districts, associations of municipalities
• Organizational components of the state and contributory organizations
• Schools, educational legal entities, hospitals, libraries
• Public research institutions and universities
• Churches and their legal entities, associations, constitutions, public benefit societies
• Enterprises owned by a public entity (e.g. municipal companies)

‍

‍

Today, subsidies for photovoltaics do not apply only to the panels themselves. Modern challenges are also supported by related technologies and preparatory work, which are crucial for successful implementation. It is thanks to this complexity that companies and public institutions can think strategically. Subsidies can thus be used not only for the power plant itself, but also for software measuring electricity consumption/production.

‍

What can you finance from subsidies?

‍

1. Photovoltaic power plant (FVE)

The basis of the project. The subsidy covers the panels themselves, inverters, mounting systems, wiring and network connections. It allows the implementation of small and large FVE from 10 kWp up to 5 MWp.

‍

2. Battery Storage (ACU)

The subsidy can also be used for systems for the accumulation of generated electricity. These help to balance the differences between production and consumption and allow more efficient use of the energy produced.

‍

3. Electrolyzers for Hydrogen Production

For advanced projects, the production of green hydrogen by electrolysis of water can also be supported. The subsidies apply to the entire system -- from water treatment to the electrolyzer itself to the storage of the hydrogen produced.

‍

4. Renovation of roofs and wiring

If the roof is in poor condition and its repair is necessary for the installation of FVE, the subsidy can also cover these costs. Modernization of the electrical wiring of buildings can also be supported.

‍

5. Energy management and project preparation

The support may also include the introduction of energy management systems, production and consumption management software, performance measurement, project documentation, technical supervision or OSH.

‍

‍

‍

Today, subsidies for photovoltaics are far from covering just the panels themselves. They cover the entire system. From preparation to commissioning. And this is a key advantage. Thanks to this, you can use the subsidy for the entire journey: from the feasibility study through the project documentation to the installation itself and the implementation of smart energy management.

‍

✅ What is a deductible expense?

‍

In simple terms: everything that makes sense for the successful implementation of the project and corresponds to the conditions of the challenge. These include:

‍

• Project documentation and connection agreement
• Procurement documentation (for public contracts)
• Construction work and technology (e.g. FVE, batteries, converters)
• Wiring and Roofing Modifications
• Implementation of energy management and monitoring of consumption
• Technical and copyright supervision, OSH
• Compulsory promotion according to fund rules
• VAT (if the applicant cannot claim it back)

‍

❌ What subsidies won't support?

‍

On the contrary, support cannot be obtained, for example, for:

‍

• Purchase of used equipment or real estate
• Taxes, administrative fees, notaries, deposits in the cadastre, etc.
• Interest, loan repayments and operating expenses
• Expenses not directly related to the project

‍

‍

Careful preparation of documentation significantly speeds up the approval of the application and minimizes the risk of delay. If you have all the documents in order, the whole process can go smoothly and within the statutory time limits. What are the documents for applying for a subsidy most often required?

‍

• Contract about connecting to the network
• Proof on the initiation of construction proceedings
• Documents on the legal relationship to the property
• Accounting documents and statements

‍

‍

Setting up your own consumption is key. It's not just a technical parameter. Without meeting the conditions of self-consumption, they simply will not give you a subsidy. Each challenge has slightly different rules, and this is where bread is often broken. Those who make high-quality preparation at the beginning will pass the subsidy smoothly.

‍

‍

1. Pre-project preparation

We will arrange an initial consultation, analyze your energy consumption and evaluate the technical possibilities of installation. We select the most appropriate challenge. we check the conditions for connection and calculate the expected production from photovoltaics, including the calculation of own consumption.

‍

2. Filing an application

We will prepare a complete application on the subsidy, including all annexes — accession agreements, budgets and affidavits. We will ensure its electronic submission through the Agenda Information System (AIS) of SFŽP.

‍

3. Vendor selection

We will help you with the choice Reliable supplier of technology. If there is a need for a public procurement procedure, we will arrange its administration in accordance with the rules of the grant title.

‍

4. Realization

We coordinate the installation itself photovoltaic power plants and possible battery storage. We monitor the progress, monitor milestones and deal operationally with any changes during construction.

‍

5. Checking and disbursing the subsidy

When finished, we prepare all documents to prove the implementation. We communicate with SFŽP, process an application for reimbursement of subsidies for fve and ensure a smooth process of reimbursement of the project.

‍

1. Can a photovoltaic subsidy be combined with a loan? 

Yes, but not with interest-free loan from the National Development Bank for the same project.

‍

2. How big does self-consumption have to be? 

Call # 1 — max. 30% to the network, challenge # 2 — min. 80% self-consumption

‍

3. Can we apply for an older photovoltaic project as well? 

Usually not -- the cost must be eligible from the date specified in the invitation.

‍

4. Who will help us prepare? 

We recommend reaching out Energy Consultant or a firm that has experience with projects funded by Modernization Fund.

‍

5. How quickly do I need to implement the project after receiving the grant? 

This depends on the specific challenge — you usually have 2 to 5 years to implement from the decision to grant aid.

‍

6. Is it possible to withdraw funds gradually, or only after the completion of the project? 

As a rule, the subsidy is paid retroactively after proof of implementation and fulfilment of all conditions. Continuous drawdown (so-called advance payment) is exceptional and subject to individual approval.

‍

7th. Can I combine a subsidy for photovoltaics with other types of public support? 

Not always.Combining with another public aid for the same expense is often not possible, but it is possible to have other subsidies in parallel for other parts of the project (e.g. FVE+electromobility).

‍

8. What if I do not achieve the required self-consumption? 

Failure to comply with this condition may lead to Reduction of the subsidy, or to its part/incomplete reimbursement. Therefore, it is a good idea to realistically plan the consumption and document it in the energy assessment.

‍

9. What are the most common mistakes when applying?

• Missing or out-of-date documentation (e.g. connection agreement, building permit)
• An inadequately described way of using energy
• Unclear budget structure
• Filing outside the deadline or without electronic signature

‍

10. Can I apply for FVE located outside the company premises? 

Yes, but only if the output of the project (electricity) will be consumed in your company and you comply with the conditionsdirect consumption and connection.

‍

11. Who controls the use of the subsidy and how? 

Inspection is carried out by the competent authorities — most often State Environmental Fund (SFZP). Firms must archive all documents andallow physical inspection of the construction as well as accounting records.

‍

12. What does the term “eligible expenditure” mean? 

This is a cost that can be recognized as part of the subsidy — e.g. purchase of technology, assembly, project documentation. Expenses outside the list of eligible items (e.g. marketing, operating expenses) cannot be claimed.

‍

I'm 13. What is project sustainability? 

The time it takes for the technology to be functional and serve its purpose — typically 5 years. During this period, there must be no sale of equipment or a major change of ownership.

‍

He's 14. How is the subsidy amount calculated? 

Usually a percentage of “eligible expenditure” -- not total investment. It is important to have accurate calculations and budget statement according to the structure of the challenge.

‍

1. Start before your challenge opens

‍

RES+ Challenge #2 is so far in preparation, but projects above 1 MWp require longer planning. Don't wait for the official launch, prepare the technical documentation, budget and clarify ownership relationships now. The same applies to RES+ calls 1 and 5. Time is your competitive advantage. With a timely start to the project, you will be able to reach a short grant window and you will not have to wait for uncertain future grant titles.

You can start today. We will prepare a whole photovoltaic project for you.

‍

2. Focus on self-consumption

‍

Most challenges require you at least 70-80% of the electricity generated from the FVE consumed. This condition is crucial for obtaining the subsidy as well as its disbursement. Take advantage energy audit or monitoring consumptionso that you have hard data on energy consumption and its evolution over the course of the year.

‍

3. Documentation is half the success

‍

Focus on providing all the necessary documents in a timely manner when applying. This may be, for example:

• Hookup agreement
• Proof of construction management
• Accurate budget statements
• Technical data sheets of equipment
• Test reports

Without this documentation It will not be possible to obtain financing. And each mistake increases the time when the money will be paid to you.

Do you want someone to guide you through the entire grant process? We're here for you!

‍

4. Do not forget about the reserve in the budget

‍

Subsidies do not cover 100% of costs. Most challenges provide a maximum of 30 to 60% of eligible expenses. You have to cover the rest from your own or external sources. Be prepared for costs that are not eligible — e.g. legal services, certain types of equipment, operating expenses.

‍

5. Get advice from experts
