As the demand for sustainability grows, more PV systems are installed worldwide. In 2022, the number of global solar PV installations has experienced a 20% growth compared to the same period in 2021. The total investment in 2022 has surpassed $170 billion. This rapid development has stemmed mostly from improvements in the efficiency and lower costs of the latest solar power systems. Indeed, PV systems represent a sustainable, low-maintenance option for anyone who wants to use power while also contributing to a greener environment. With the growing trend for more and more sophisticated PV systems, power supplies need to keep up in terms of reliability and performance. Below we will review more details on how to choose the best power supply solutions for PV systems.
All About PV Power Supply Systems
PV systems are more widespread for more than a reason: they are eco-friendly, cost-effective, and provide a high ROI in the long term. So while the initial installation costs might be high, PV systems will reduce the electricity bills in the long run while also creating no noise or pollution. Another benefit of this technology is that PV systems are modular, making it relatively easy to expand as the demand increases over time.
However, just like all renewables, solar energy is not always available and is affected by the state of the weather. For example, PV systems might not generate power at night, on a rainy or cloudy day. To satisfy the power demand, smart grid owners and homeowners might have to rely on more traditional, polluting energy sources to use power.
For this reason, PV systems usually do not consist of a solar PV array but also include a battery bank or other similar types of battery storage systems (BESS). Thanks to a BESS, PV systems can store excess energy and release it at night or on days with adverse weather conditions. Other components of a photovoltaic system usually include a charge controller, an inverter, a utility meter, and an electric grid. The correct installation of all these components, as well as the power supplies used to power them, determine how efficient the solar panels are.
In terms of power, PV systems are generally classified according to their functional and operational requirements, their component configurations, and how the equipment is connected to other power sources and electrical loads. The two principal classifications are gridconnected or utility-interactive systems and stand-alone systems. Photovoltaic systems can be designed to provide DC and/or AC power service, can operate interconnected with or independent of the utility grid, and can be connected with other energy sources and
energy storage systems.
In particular, grid-connected or utility-interactive PV systems are designed to operate in parallel with and interconnected with the electric utility grid. The primary component in grid-connected PV systems is the inverter, or power conditioning unit (PCU). The PCU converts the DC power produced by the PV array into AC power consistent with the voltage and power quality requirements of the utility grid and automatically stops supplying power to the grid when the utility grid is not energized.
Stand-alone PV systems are designed to operate independent of the electric utility grid and are generally designed and sized to supply certain DC and/or AC electrical loads. These types of systems often use batteries for energy storage and may be powered by a PV array only, or may use wind, an engine-generator, or utility power as an auxiliary power source in what is called a PV-hybrid system.
Regardless of the specific type, PV systems’ stable, continuous operation is mostly possible when their electric circuits include reliable power supplies. The power module design of a PV system is one of the most crucial steps to guarantee the long life span of a PV system. Selecting scenario-based power supplies for PV systems is only half of the process. It is equally crucial to rely on an experienced power supply solutions provider with comprehensive solutions and full support at every stage of the module selection process.
