How Does a Commercial Solar System Work?
Solar panel systems harness the sun’s energy to generate substantial electricity. At a basic level, photovoltaic cells, commonly known as solar cells, absorb sunlight and undergo a series of steps to produce electrical current, a phenomenon called the photovoltaic effect. The resultant electrical current is then captured by wires and plates, ultimately transforming into usable electrical energy directed to your property or factory.
For a comprehensive understanding of how a commercial solar system works, we outline the steps involved. Additionally, to enhance the efficiency of solar panels, we provide some valuable tips to optimize your system. Read on to maximize the benefits of your solar energy system.
How Does a Commercial Solar System Work Step-by-step?
Step 1: Activation by Sunlight
Solar panels consist of layers of silicon cells enclosed in a glass casing with a special film, a metal frame, and wiring. Panels are arranged in an organized series and positioned in expansive outdoor areas or rooftops for optimal efficiency. During daylight hours, the solar cells, or photovoltaic cells on the panel, absorb sunlight, initiating the activation process.
Step 2: Electricity Production by Solar Cells
Each solar cell incorporates a semiconductor wafer composed of two silicon layers, one negatively charged and the other positively charged, forming an electric field. When sunlight hits these photovoltaic solar cells, it releases electrons in the semiconductor wafer. These liberated electrons move within the wafer’s electric field, generating an electrical current.
Step 3: Conversion of Electrical Energy
At this juncture, your commercial solar system has successfully converted solar rays into electricity. However, the produced electricity, termed direct current (DC), is unsuitable for powering factories or offices. It needs to be transformed into an alternating current (AC) to make it usable.
To accomplish this, an inverter is employed to convert DC electricity into AC electricity. Depending on your solar panel system, a single inverter for the entire setup or micro-inverters linked to individual panels can be installed to facilitate this conversion.
Step 4: Utilization of Converted Electricity
Once solar energy is converted from DC to AC electricity, it is distributed throughout the property to power lights, machinery, and other electrical devices inside the premises. Solar energy operates seamlessly, mirroring the electricity distributed by your local utility company.
Notably, there is no need to modify machinery, appliances, or other electrical products to utilize solar energy. Since your commercial property remains connected to the traditional power company, you can rely on their electricity during solar shortages.
Step 5: Benefit from Meter Measures
Surplus energy can be used when solar panels cannot absorb energy due to adverse weather conditions. The excess can be sent to the utility company’s grid when you generate more electricity than necessary for your company’s operations. In return, the local electricity provider offers credits.
This process, known as net metering, allows you to access electricity from the company without concerns during times of need. To leverage this feature, installing a smart electric meter is essential. This meter lets you monitor energy flow to and from your property, ensuring efficient energy management.
How to Optimize Your Solar Panel Output ?
1. Integrate Solar Batteries:
While solar panels generate energy only when the sun is shining, you can ensure a continuous power supply by incorporating solar batteries. These batteries store excess energy, enabling your property to utilize electricity around the clock, even during periods of limited sunlight. This innovation eliminates the need to switch to the power grid at night, enhancing the overall efficiency of your solar system.
2. Opt for High-Quality Solar Systems:
The efficiency of solar panels is crucial for maximizing energy conversion. Photovoltaic cells within solar panels transform solar energy into electricity, but not all systems can harness the same amount of sunlight. The efficiency, represented as a percentage, indicates the proportion of sunlight converted into energy. Recent advancements have elevated solar technology, with some companies achieving 15% and 20% efficiency rates. Although the initial cost of commercial solar may be higher, investing in a more efficient model yields superior results, leading to substantial long-term savings.
3. Prioritize Regular Maintenance and Cleaning:
Ensuring the cleanliness of your commercial solar panels is paramount for optimal functionality. Accumulated dust and debris can hinder efficiency, and moisture-induced hardened mud poses a serious threat. Professional maintenance and cleaning services are recommended to assess the condition of the panels and mitigate the risk of damage. Engaging trained experts not only safeguards your panels but also minimizes the potential for injuries during the cleaning process.
4. Consider CPV Cells in Solar Panels:
Explore solar panels with Concentrated Photovoltaic (CPV) cells to enhance efficiency. CPV technology concentrates sunlight on highly efficient solar cells, offering efficiencies exceeding 46%, surpassing traditional PV panels with efficiencies capped at around 22%. While CPV panels have a higher price tag, their superior efficiency justifies the investment. If budget constraints arise, opt for high-quality traditional solar panels as a viable alternative.
5. Ensure Expert Installation:
Choosing a right commercial solar company for solar installations is pivotal for optimal sunlight exposure and electricity generation. Key considerations include the angle and orientation of the panels. Generally, panels should be positioned at an angle of 18 to 36 degrees to capture maximum sunlight. In the northern hemisphere, panels should face south, while in the southern hemisphere, a north-facing orientation is ideal. Adequate gaps between the ground and panels facilitate air circulation, preventing photovoltaic cells from overheating. Professional expertise is crucial for proper installation, considering factors like temperature levels to maintain efficiency.
6. Implement Ongoing Monitoring:
Monitoring your commercial solar system’s output is essential for assessing its efficiency over time. Connecting the panels to energy management software lets you track energy production levels. Regular monitoring helps identify sudden drops in efficiency, enabling timely interventions to optimize energy output. Collaborate with your contractor to explore efficient monitoring solutions tailored to your system’s needs.
