Maintaining and Maximising the Efficiency of Your Solar PV System

Considering that over 1,000,000 rooftops in Ireland are suitable for solar panels, we believe that no rooftop should be left behind! Investing in a solar PV system is a significant step towards energy independence and sustainability. To ensure you get the most out of your system, it’s crucial to maintain it properly and optimise its efficiency.

Here’s how you can achieve that:


1. Regular Maintenance:

  • Routine Cleaning: Solar panels are generally low maintenance, but keeping them clean ensures maximum sunlight absorption. Rain can wash away most debris, but you may need to occasionally clean them manually to remove dust, bird droppings, or leaves. Use a soft brush or sponge with water to avoid scratching the panels.

  • Annual Inspections: Schedule an annual inspection with a certified professional. They will check for any damage, wiring issues, or performance drops. This helps in identifying and addressing minor issues before they become major problems.

  • Monitoring System Performance: Many solar PV systems come with monitoring software that allows you to track energy production in real-time. Keep an eye on these metrics to ensure your system is performing as expected.


2. Maximising Efficiency:

  • Optimal Energy Use: Align your energy consumption with peak solar production hours. Use high-energy appliances like washing machines, dishwashers, and electric vehicles during the day when your solar panels are generating the most electricity.

  • Battery Storage: Integrating a battery storage system allows you to store excess energy produced during the day for use at night or during cloudy periods. This maximises your solar investment and increases your energy independence.

  • Smart Meters: Install a smart meter to monitor your energy usage accurately and help you manage your energy consumption more efficiently. Smart meters also enable you to participate in the Clean Export Guarantee (CEG) scheme, allowing you to get paid for the excess energy you export to the grid.

  • Minimising Shading: Ensure that your solar panels are not shaded by trees, buildings, or other obstructions. Even partial shading can significantly reduce the efficiency of your solar PV system.


By maintaining your solar PV system and maximising its efficiency, you can ensure that you reap the maximum financial and environmental benefits over its lifespan.
