Photovoltaic systems have established themselves as one of the most effective solutions for reducing energy costs and making a commitment to environmental protection. Despite the many benefits, building a PV system requires careful planning and awareness of the entire process. Here are five key things to know before you start building your PV system.
- What you need to know about system size
The size of the PV system you'll build depends on several factors, including your electricity usage and the availability of solar energy in your region. Before you take steps to build a system, it is important to do an electricity consumption analysis. This can be achieved by:
- Reviewing last year's electricity bills to identify seasonal fluctuations.
- Determining your long-term goals - whether you want the system to cover 100% of your consumption or serve as an additional source of power.
Our specialists can use this data to calculate the number of panels, inverter capacity, and battery options if needed.
- Selecting components for the system
The quality of the components is critical to the efficiency and longevity of the PV system. Key components include:
- Photovoltaic panels: Different types of panels offer different efficiencies and price ranges. Monocrystalline panels are the most efficient but also the most expensive.
- Inverters: The central element that converts the electricity produced from DC to AC. Choosing a quality inverter is essential for system reliability.
- Energy storage system (batteries): If you want energy independence or a backup source in case of an emergency, batteries are an important component. However, they increase the initial investment.
It is advisable to choose certified brands with a long warranty period and good after-sales service.
- Installation process and permits
The installation process involves several stages that require professional assistance:
- First, you need to make sure that you have the right location to install the panels that will provide maximum exposure to sunlight during the day. Roofs are most commonly used, but open spaces in the yard or facades are also an option. It is important that the location be oriented to receive maximum sun exposure.
- Obtaining permits: Next, you must obtain the necessary permits from local authorities, which include safety inspections and compliance with building and energy standards.
- Execute the installation: Working with a professional company that has experience installing PV systems will make the process easier and ensure that all steps are done in accordance with regulations. Professional installation ensures safety and compliance with all regulations.
- Financing and subsidy programs
Photovoltaic systems require an initial investment, but various financing programs can make these technologies more accessible:
- For example, the BG-RRP-4.026 programme provides partial funding for the installation of household PV systems.
- Bank loans for green energy: Some banks offer favourable terms for loans for renewable energy investments.
- ROI: A well-planned system can pay for itself in 5-8 years, depending on its size and current electricity costs.
- Maintenance and monitoring of the system
Once you install the PV system, it is important to have a plan for its maintenance and monitoring. Photovoltaic panels do not require much maintenance, but checking the system regularly can prevent potential problems and ensure that it is operating at maximum efficiency. Many systems include remote monitoring capabilities, allowing you to monitor energy production and detect potential faults quickly. Regular maintenance by specialists can also extend the life of the system and optimize its performance.
Conclusion
Investing in a photovoltaic system is not only financially beneficial, but also environmentally responsible. Preparing yourself with the right information about system size, components, installation process, financing options and maintenance will ensure that your system runs efficiently and smoothly in the long run.
