Installing photovoltaic panels has become an investment for individuals, not only because it can reduce electricity costs, but also because it offers the possibility of becoming a prosumer (a consumer who also produces electricity). Likewise, developing photovoltaic parks to serve communities has become an extremely popular business idea in Romania.
Whether you are a homeowner or a company looking for a project involving the installation of solar panels at your property or even in a photovoltaic park, we can provide the services needed to implement it. Below you will find details about our solutions for both categories of customers.
What does a photovoltaic-panel installation project involve for homeowners?
If you own a house and want to install solar panels in Bucharest/Ilfov so that you are no longer dependent on the national electricity distribution system, or so that you can become a prosumer, we can assist you from the initial feasibility-study stage through to project implementation.
To prepare an offer, we need the following information:
- Electricity bills from the last 3–4 months;
- Load curves (IDBs), which you can obtain from your electricity supplier;
- Number of people in the household;
- The types of panels you would like.
Based on this information, we can:
- Assess your electricity consumption;
- Estimate energy production;
- Prepare the technical project documentation.
Below, we explain the stages leading up to the installation of the photovoltaic panels.
Steps for implementing a residential project
After receiving the necessary information, our specialists will:
- Check the technical characteristics of the roof, specifically its structure, orientation and pitch, to ensure the most efficient installation possible;
- Estimate solar production based on the location and solar irradiation;
- Calculate the required number and type of panels, as well as the inverter and batteries, if you wish to store electricity;
- Determine the appropriate type of mounting structure for the panels.
After these stages, the photovoltaic system will be installed, tested and commissioned. The final steps involve obtaining the Technical Connection Approval (ATR) and signing the prosumer contract.
From a technical perspective, systems of 3–10 kWp are commonly chosen by homeowners, with the entire project taking a maximum of approximately one month.
What does a photovoltaic-park project involve?
Our services are also available to those wishing to invest in photovoltaic parks. In this case, the project is more complex, and the first step is to select land that meets the following conditions:
- It must be located outside the built-up area (extravilan);
- It must permit energy-related construction;
- It must have access to the national distribution network.
Once these requirements have been met, our specialists will conduct a feasibility study, which includes:
- Technical and economic analysis;
- Estimation of annual production;
- Calculation of investment versus return;
- Determination of the operating mode, which may be on-grid, self-consumption, or hybrid.
Installing photovoltaic panels in a park also requires obtaining various approvals and permits, specifically:
- Urban-planning certificate;
- Environmental approval;
- Technical Connection Approval (ATR);
- Building permit;
- Electricity-generation approval from the National Energy Regulatory Authority (ANRE).
Once the technical documentation has been prepared, we proceed with designing the solar-panel park.
Steps for installing photovoltaic panels in a park
Installing solar panels in a photovoltaic park involves:
- Preparing the project, including selecting the types of panels that will provide the best performance, as well as the inverters and electrical connections;
- Constructing the park;
- Purchasing and installing all equipment;
- Testing and commissioning the park;
- Connecting it to the national electricity network;
- Proper operation and maintenance of the panels.
In Romania, both small and large photovoltaic parks can be commissioned, with capacities ranging from 400 kWp up to 1,000 MWp. Installation can take anywhere from 2 months to one year, depending on the park’s size and capacity.
How is the price of photovoltaic-panel installation calculated?
If you would like an offer for solar-panel installation, the cost consists of:
- Equipment;
- Installation;
- ANRE and ATR approvals;
- Preparation of the prosumer application/file.
Because these costs vary between individuals and legal entities and depend on the type of project, the company invites you to contact them directly for a quotation.
How to avoid common problems associated with solar-panel installation
Here are some of the most common problems encountered when installing photovoltaic panels:
- Delays in obtaining approvals and permits from the authorities, caused either by incomplete documentation or delays in installing meters;
- Installation problems, including choosing an unsuitable location for the panels, using an inadequate mounting structure, poor cabling, or selecting an undersized inverter;
- Low system performance caused by low-quality panels or incorrect system sizing;
- Problems with equipment servicing and warranties when devices that have not been approved by ANRE are selected.
Apart from the first category of problems, which is often dependent on the authorities, the other issues can be avoided by working with an experienced installer, helping ensure that your investment provides maximum benefits. Contact us for a personalized offer!
