How Much Energy Can My Solar Panel Generate?

If you have been considering solar panels for your business site, this question must have crossed your mind: " How much energy does a commercial solar panel produce?” And rightly so, knowing your solar panels' energy output is important to measure their effectiveness and the potential savings on your energy bills. At Beat Energy™, we’re here to break down the factors influencing solar panel energy generation and help you understand what to expect.

The Basics of Solar Panel Energy Generation

Solar panels generate energy by converting sunlight into electricity through photovoltaic (PV) cells. The amount of energy your solar panels can produce depends on various factors, such as the type of panels, their efficiency, the location of your installation, and the amount of sunlight your area receives. If you are thinking about reducing your carbon footprint and saving on energy bills, then going solar is definitely worth considering. Just imagine the positive impact on the environment and your wallet.

How Efficient Are Commercial Solar Panels?

While the older solar panels had an efficiency of about 6%, with rapid advancement in solar technologies, the modern-day models can reach between 15% and 25%. While this may seem like a small improvement, it translates into significant financial gains for businesses trying to cut down annual energy costs and save thousands of dollars.
With ongoing innovations, solar technology has reached an even higher efficiency rate in lab conditions. As a business owner, you can be confident that your smart solar panels are incredibly effective and will maintain their optimal capacity for almost 25-30 years. Even after that period, the panels degrade very slowly, making them a fantastic investment that will contribute to a more profitable and sustainable future.

How To Calculate Your Solar Panel’s Energy Output

Use this simple formula to estimate the energy output of your solar panels:

Number of panels x Power in watts x Average hours of direct sunlight = Energy Output (kWh)

This approach makes it easy to calculate energy production by week, month and year. For example, if you have 20 panels rated at 300 watts each, and your location receives an average of 6 sunlight hours per day, the energy output calculation for one year is:

20×300×6×365 = 13,140,000 kWh per year

However, real-world conditions can affect your solar panels' energy generation. Shading from trees and obstructions from nearby buildings can cast shadows on your panels, impacting and reducing efficiency. Weather conditions like cloudy and rainy days will limit the sunlight your panels receive and lower the energy output. Solar panels gradually lose efficiency over time but come with a warranty guaranteeing they will retain 80%-90% of their original efficiency even after 25 years.

Maximising Your Solar Panel’s Energy Production

To get the most out of your solar panels, consider the following tips:

  • Regular Maintenance: Keep your solar panels in top shape by getting them serviced from time to time. A regular six-month wash and clean will keep your commercial solar panels free from grime and dirt and allow them to operate at full capacity. Additionally, the inverter units should be checked and serviced by a professional technician at least once a year to ensure fault-free performance.
  • Optimal Placement: Work with a professional installer to ensure your commercial solar panels are installed for optimal performance. These experts have the knowledge and experience to help determine the best placement and angle for the panels to catch maximum sunlight throughout the day.
  • Monitor Performance: Get the most out of your solar energy systems with smart monitoring systems. These innovative devices provide real-time data helping you track your panels’ performance, energy production, energy consumption, overall efficiency, and system health. You can also keep a close eye on any issues and malfunctions. With a monitoring device, you can make the most of your investment and minimise downtime.
