Investing in a photovoltaic system is one of the most popular and promising strategies for optimizing electricity costs and reducing a business's carbon footprint. It can be a source of significant long-term savings, but also involves a number of technical and financial aspects that need to be carefully considered. In this article, we'll look at all the key elements to consider before investing in a PV installation for your business.
1. Analysing the energy needs of the business
Before you start any planning or calculations, you need to have a clear idea of your business's energy needs. Accurate power consumption analysis is key to determining the size and capacity of the system you will need.
Key issues to consider:
- What is your average monthly electricity consumption?
- What are the peak loads during the day and during the year?
- How much of this consumption do you want to cover with the PV system? Your goal may be to partially cover your needs or to completely switch to solar power.
Stages of analysis:
- Extract data from the last 12 months - the analysis should include different seasons to account for any variation in consumption.
- Estimate future energy needs - are you planning to expand the business, introduce new equipment or make workflow changes that will increase energy consumption?
- Calculate the appropriate capacity - specialists can help you determine the optimal system size based on your consumption and goals.
If you're not sure exactly how to make this assessment, Inter Power is here to assist you with professional advice and a precise calculation of your energy needs so you can make an informed decision.
Technical aspects and installation requirements
Once you have a clear idea of your energy needs, the next step is to analyse the technical requirements for installation. The location, orientation and pitch of the roof are essential for the efficiency of the PV system.
Location assessment:
- Roof orientation and tilt - south exposure is ideal for Bulgaria, with a tilt of 30 to 35 degrees to ensure maximum use of sunlight.
- Shading - analyse the presence of obstructions such as trees, antennas or tall buildings that may cast shadows on the panels. Shading even a small portion of the system can drastically reduce its performance.
- Roof quality and condition - check that the roof is in good condition and ready for the panels to be installed. If the roof is in need of repair or strengthening, this should be done prior to installation.
Ground installations:
If the roof of the building is not suitable, a ground installation may be considered. This requires additional space and a suitable layout, but often offers greater flexibility in terms of orientation and tilt of the panels.
3. Financial aspects: investment, return and financing
One of the most important steps in deciding on an investment in a PV system is the assessment of costs and returns. This analysis includes not only the initial investment, but also the maintenance costs as well as the potential revenue from the sale of surplus energy.
Initial investment:
- Panel price - the quality of the panels is a critical factor. Invest in panels from established manufacturers with a long-term warranty.
- Inverters - these are key components that convert the energy produced into usable current. Inverters typically have a shorter life than panels (10-15 years) and may require replacement.
- Installation and connection - professional installation is important for proper system operation. Include installation costs in the budget, which can vary depending on the complexity of the project.

Funding opportunities::
- Subsidy programs - there are various national and European programs for financing renewable energy projects in Bulgaria that can significantly reduce the initial investment.
- Loans and leasing - banks and financial institutions often offer special credit lines with preferential terms for green projects.
- Power Purchase Agreements - some companies offer the option to install a system on your sites, with you only paying for the energy produced, without bearing the initial cost.
Return on Investment (ROI):
Typically, payback is expected within 5 to 10 years, depending on system size and regional conditions. It is important to make a long-term forecast that includes changes in electricity prices and future maintenance costs.
4. Administrative procedures and regulatory requirements
Before beginning installation, you should familiarize yourself with the administrative and regulatory requirements. In Bulgaria, the process may involve different steps that vary depending on the scale of the project and the location.
Basic steps:
- Preparation of project documentation - the project must be prepared by qualified specialists and meet all regulatory requirements.
- Permits from the municipality and the energy operator - permits are required for installation and connection to the grid.
- Surplus energy purchase agreement - if you plan to sell the surplus energy produced, you must sign an agreement with the energy operator.
"Inter Power" can assist you in the entire process - from the preparation of documentation to the complete installation of the system and its connection to the network.
5. Long-term maintenance and monitoring
The efficiency of a PV system depends not only on the quality of the installation, but also on regular maintenance and monitoring. Neglecting maintenance can lead to lower productivity and even failures.
Key aspects of maintenance:
- Panel cleaning - accumulation of dust, leaves or snow can reduce performance. Schedule regular cleaning, especially if the system is installed in industrial areas.
- Real-time monitoring - modern systems offer remote monitoring capabilities, allowing you to monitor performance and identify potential problems.
- Periodic checks - regular checks of inverters, wiring and other components will extend the life of the system and ensure safety.
6. Sustainability and long-term business benefits
Photovoltaic systems are not only economically viable but also environmentally sustainable. They can enhance your business reputation and make it more attractive to customers and partners who value corporate responsibility and sustainability.
Key benefits:
- Reducing the carbon footprint - switching to solar energy is a significant contribution to environmental protection.
- Cost stability - a photovoltaic system gives you independence from fluctuations in electricity market prices.
- Diversification of energy sources - using different energy sources makes your business more flexible and resilient to future changes in regulations and market conditions.
Investing in a PV system for your business is a decision that requires a strategic approach and careful analysis. If the planning is done correctly, the system can result in significant savings, energy independence and improved environmental sustainability for your business.
