If you’ve invested in a home solar system, you’ve taken a significant step towards energy independence and reducing your carbon footprint.
But to truly reap the rewards of your investment, it’s crucial to optimise your system’s performance.
Maximising your solar system’s efficiency can help you slash your electricity bills, increase your energy independence and contribute to a more sustainable future.
This blog explores how you can squeeze every last drop of value from your home solar system.
Understanding your solar generation
Your solar panels’ output isn’t constant throughout the year, or even day-to-day. Understanding these generation patterns is key to optimising your energy use.
In the UK, solar generation peaks during summer months, with longer days and more intense sunlight. During winter, output naturally decreases.
Daily generation patterns matter, too. Typically, your system will generate the most electricity between 10am and 4pm in summer, and 11am to 2pm in winter.
Keeping an eye on your system’s monitoring app will help you pinpoint your peak generation hours. This knowledge forms the foundation for maximising your solar benefits.
Increasing self-consumption
Self-consumption refers to using the electricity your panels generate, rather than exporting it to the grid. The more solar energy you use directly, the less you need to buy from your energy supplier. It’s a simple concept with powerful implications for your energy bills.
To boost your self-consumption, try to run energy-intensive appliances during peak solar generation times. Load the washing machine or dishwasher before you leave for work and set them to run mid-morning. If you work from home, schedule your most energy-intensive tasks for the middle of the day. Every kilowatt hour (kWh) you self-consume is one you don’t have to buy from the grid.
Optimise your appliance use
Shifting your energy use to daylight hours can significantly increase your solar system’s efficiency.
Use timers or smart plugs to automate appliances like your washing machine, dishwasher or tumble dryer. Many modern appliances have built-in delay timers, so put them to good use.
And don’t forget about heating and cooling. In winter, run your heating system during sunny hours to warm your home, then close doors and windows to trap the heat. In summer, cool your home during peak solar hours and use blinds or curtains to keep the heat out.
Electrify your home
As your gas appliances reach the end of their life, consider replacing them with more efficient electric alternatives. This strategy allows you to power more of your home with solar energy. When shopping for new appliances, prioritise energy efficiency. While they might cost more upfront, they’ll save you money in the long run.
Monitor your system’s performance
Regular monitoring is crucial for getting the most out of your solar system. Most modern systems come with monitoring apps that show your generation and consumption in real-time. Familiarise yourself with these tools. They can help you understand your energy patterns and identify opportunities for optimisation.
Keep an eye out for unexpected drops in generation, which could indicate issues with your system that need addressing. Swift action can prevent minor problems from becoming major headaches.
Upgrade your system with optimisers
If your roof experiences partial shading or has sections facing different directions, consider installing solar panel optimisers. These clever devices can significantly boost your system’s performance.
Optimisers work at the individual panel level, ensuring each panel performs at its best regardless of shading or orientation. They can increase your overall energy yield, especially in less-than-ideal conditions. As a bonus, many optimiser systems provide detailed panel-level monitoring, helping you spot and address issues quickly.
Stay on top of maintenance
Solar panels are remarkably low maintenance but they’re not entirely ‘fit and forget’. Regular cleaning can prevent dust and debris from reducing your panels’ efficiency. In most cases, rain will do the job, but an annual clean can help maintain peak performance.
Keep an eye on your panels and surrounding areas. Trim back any overhanging branches that might shade your panels or drop leaves onto them. If you notice any issues – like a sudden drop in generation or physical damage to a panel – don’t hesitate to call in a professional.
Battery storage
Adding a battery to your solar system can take your energy independence to the next level. Batteries allow you to store excess solar energy for use when the sun isn’t shining, further increasing your self-consumption.
However, batteries are a significant investment. Consider factors like your current self-consumption rate, electricity prices and future energy needs when deciding if a battery is right for you. As the technology improves and prices drop, batteries are becoming a more attractive option for many households.
Review your electricity plan
The energy market evolves constantly, with new tariffs and offers appearing regularly. So, make a habit of reviewing your electricity plan at least annually. Look for plans that offer good feed-in tariffs for the excess energy you export to the grid.
If you have a battery or are considering one, look into time-of-use tariffs. These can allow you to charge your battery with cheap off-peak electricity and use it during expensive peak times.
Use online comparison tools to ensure you’re getting the best deal. A small investment of time here can lead to significant savings over the year.
