In this informative article, we’ll walk you through the process of evaluating and optimizing your solar system’s performance.

We’ll also address common issues that can affect Prosolar Global offer solutions to get your system back on track.

How to Assess Your Solar System’s Performance:

Understand Key Performance Indicators (KPIs):

Before you begin monitoring your solar system, it’s essential to grasp the Key Performance Indicators (KPIs) that gauge its effectiveness:

  • Energy Yield: Measured in kilowatt-hours (kWh), this indicates the amount of energy your system generates.
  • Efficiency: This represents the ratio of energy output to the solar panel’s surface area, usually expressed as a percentage.
  • Performance Ratio: This compares the actual output to the theoretical output under standard conditions.
  • Temperature Coefficient: This measures your system’s performance under varying temperatures.

Utilize Monitoring Software:

Most modern solar systems are equipped with monitoring software accessible through smartphone apps or web portals. These platforms provide real-time data on:

  • Energy production
  • Energy consumption
  • Efficiency
  • Environmental benefits like CO2 savings

Regular Visual Inspections:

Conduct periodic visual inspections of your solar panels and related components. Look out for:

  • Dust or debris on the panels
  • Signs of physical damage
  • Any shading caused by new obstructions
  • Status lights on your inverter

Professional Maintenance:

It’s advisable to schedule a professional check-up at least once a year. A certified technician can:

  • Test the inverter and other electrical components
  • Inspect the mounting and structural integrity
  • Verify the system’s electrical output aligns with initial projections

Analyze Your Electricity Bill:

  • Your monthly electricity bill can also serve as a performance indicator. A properly functioning solar system should result in reduced electricity costs. If you notice your bills aren’t decreasing as expected, it may be time for a system check-up.

Monitor Weather Patterns:

  • Weather conditions can impact your solar system’s performance. By comparing its output on sunny days versus cloudy or rainy days, you can gain insights into its efficiency.

Common Solar System Issues:

  • Reduced Efficiency Due to Debris: Accumulation of dirt, dust, and debris is a common problem that can significantly reduce solar panel efficiency.
  • Shading: Shading caused by trees, buildings, or other obstructions can substantially diminish your solar panels’ effectiveness.
  • Inverter Problems: The inverter is crucial for converting DC electricity from the panels into usable AC electricity for your home. If it fails, your system won’t produce energy.
  • Micro-Cracks: Solar panels can develop micro-cracks due to various factors, such as thermal cycling, manufacturing defects, or hailstorms.
  • Hot Spots: Hot spots occur when some cells in a solar panel become much hotter than others, often due to shading or soiling, leading to reduced performance and potential damage.
  • Degradation Over Time: All solar panels degrade over time, losing approximately 0.5% to 1% of their efficiency each year.
  • Wiring and Connection Issues: Loose or corroded connections can reduce system performance and pose fire risks.
  • Software Glitches in Monitoring Systems: Sometimes, issues may stem from monitoring software providing inaccurate data rather than the solar system itself.

What to Do If Your Solar System Isn’t Performing as Expected:

Step 1: Check Your Monitoring System: Update and properly configure your monitoring software to ensure accurate data.

Step 2: Conduct a Visual Inspection: Clean your panels and remove obstructions that could be causing shading.

Step 3: Review Key Performance Indicators (KPIs): Compare current data with past performance or expected benchmarks.

Step 4: Inspect the Inverter: If issues are detected, consult the user manual or contact a professional for further diagnosis.

Step 5: Examine Electrical Connections: Turn off the system and inspect all electrical connections. If uncomfortable doing this, seek professional assistance.

Step 6: Consider Environmental Factors: Review weather data to identify any environmental factors affecting your system’s performance.

Step 7: Consult a Professional: Schedule an appointment with a certified solar technician to diagnose and resolve the issue.

Step 8: Explore Upgrades: Discuss potential upgrades with your solar provider to enhance your system’s performance.
