How to Ensure Your Solar System Is Performing Properly

Harnessing Winter Sun: Ensuring Optimal Solar Performance in Colder Months

Many homeowners and businesses wonder: does solar energy still make sense during the winter months? The answer is a yes! Solar panels are effective year-round, even in colder, cloudier months. Here’s what you need to know about solar performance in winter and how to check if your system is working properly.

Does Solar Work in Winter?

While it’s true that shorter days and lower sun angles can reduce energy production, solar panels still generate electricity in winter. Snow, clouds, and overcast skies can influence output, but they don’t stop solar panels from working. In fact, cold temperatures can actually improve panel efficiency, as they operate better in cooler conditions.

Key points:

Sunlight still reaches your panels: Even on cloudy days, solar panels can produce power.
Snow can temporarily block sunlight: Snow accumulation may reduce output; however, panels are often installed at angles that allow snow to slide off easily.
Shorter daylight hours: Expect lower energy production due to fewer hours of sunlight, but overall efficiency remains high during clear winter days.

How to Check Whether Your Solar System Is Working Properly

To ensure your solar system is performing optimally during winter, regular checks are essential. Here are some simple steps:

Monitor Your Production Data:
- Use your solar monitoring system or app to track daily and monthly energy production.
- Compare current output with previous months or similar winter periods to spot any significant drops.
Inspect Your Panels:
- Periodically check for snow, debris, or dirt on the panels.
- Gently clear snow if it’s obstructing sunlight, using a soft brush or squeegee.
Look for Physical Damage:
- Inspect for cracks, discolouration, or damaged panels, especially after storms.
Check Your inverter:
- Ensure the inverter display shows normal operation.
- Any error messages or unusual readings should be addressed promptly.
Schedule Professional Maintenance:
- Annual inspections by a qualified technician can identify issues you might miss and ensure optimal performance. Book a solar clean with MPV Solar.

Monitoring

Our monitoring service is included with all residential installations, allowing clients to track the performance of their solar systems. We also actively monitor the system to ensure it operates at peak efficiency.

Cleaning & maintenance

We offer a comprehensive scheduled maintenance service to keep your solar system running optimally, which includes inspecting all electrical components, analysing historical data, conducting a thermal imaging survey to detect potential faults in the solar modules, and providing a regular cleaning schedule to prevent dust buildup and enhance efficiency

System capacity increases

Adding household items like a pool or air conditioning can increase electrical demand, and if your solar system can’t accommodate this, we can expand it by managing applications to local supply authorities and integrating new components with your existing setup.

Energy storage

While this technology is continually evolving, there are already systems available that can store your surplus energy instead of sending it back to the grid. We offer storage-ready solutions that facilitate future storage additions.

Design & specification assistance

We frequently collaborate with architects and engineers to support solar specifications for new homes and developments. We evaluate plans and designs before the tender process, providing guidance on placements, inverter locations, and specifications for both modules and inverters.

Audits & testing

Our audit and testing services ensure your solar energy system operates at peak efficiency by conducting comprehensive assessments of the inverter and solar panels, using advanced diagnostic tools to identify potential issues such as electrical inefficiencies and environmental damage.

FAQs about Solar Systems in Winter

Your questions about MPV Solar answered.

Does solar energy still generate electricity during winter?

Yes, solar panels can generate electricity in winter, even on cloudy days. While production may be lower than in summer, panels still produce useful energy.

Can snow and ice affect the efficiency of my solar system?

Snow and ice can temporarily reduce output by covering the panels. However, panels are typically installed at angles that help snow slide off, restoring efficiency once snow melts or is cleared.

Do colder temperatures impact the performance of my solar panels?

Colder temperatures actually can improve solar panel efficiency, as panels tend to perform better in cooler conditions, provided they are free of snow and debris.

How can I check if my solar system is working properly in winter?

Use your monitoring system to track energy production. Regularly inspect panels for snow or debris, and ensure your inverter shows normal operation. Schedule annual professional inspections for optimal performance.

Is energy production in winter worth the investment?

Yes, even with reduced output, solar can still offset energy costs in winter. Plus, long-term benefits and energy savings make it a smart, sustainable choice year-round.
