How to Maximise Your Solar Panel Generation During the Summer

June brings with it the longest days of the year and, for homeowners and businesses in Northern Ireland, the perfect opportunity to maximise the benefits of solar energy. With increased daylight hours and more consistent sunshine, your solar panels are working at their peak — but are you getting the most out of your system?

At Solarfix, we specialise in delivering smart, honest solar solutions for homes, farms, and businesses across Northern Ireland. In this article, we’ll share practical advice on how to optimise your solar panel output during June and the rest of the year, reduce your electricity bills, and boost your return on investment — whether you’re already generating clean energy or still exploring your options.

Use Power When the Sun Is Shining

If you're home during the day and can see your solar system is performing well, that’s the ideal time to run your high-consumption appliances. Turning on your washing machine, dishwasher, or tumble dryer when the sun is at its strongest allows you to power them directly from your solar system, rather than drawing from the grid or your battery. To get the most out of your solar generation, it’s a good idea to space these appliances out throughout the day. This helps balance your energy use and ensures your solar panels are consistently covering the load.

By doing this, you're reducing the strain on your battery or the need to import energy from the grid during the evening. When it comes to evening use, you’ll typically only be powering low-consumption items, meaning your overall electricity bill will be even lower. The key is to use as much of your solar power as possible rather than exporting it back to the grid. Since most customers pay around 30p per kWh for imported electricity but only receive about 10p per kWh (current Power NI export rate in June 2025) when exporting, maximising self-consumption is the smartest way to achieve the greatest savings and shorten your payback period.

Start with the Right Storage: Home Batteries Matter

One of the most effective ways to maximise your solar energy is to pair your system with a home storage battery. With more solar power being generated during long summer days, having somewhere to store that excess energy allows you to use it later — when the sun goes down or your energy usage increases.

As a Duracell Energy Platinum Partner and a SolarEdge Preferred Partner, Solarfix supplies and installs high-performance storage solutions from two of the most trusted names in the industry. For many households, a 5kW battery storage or 10kw battery storage solution strikes the right balance between cost, performance, and capacity, depending on the individual customers electricity needs. With battery storage, you're no longer limited to using your solar energy only while the sun is shining. Instead, you can spread your usage across the day and night, reducing your dependency on grid electricity and increasing savings.

Smart Energy Management with MyEnergi Devices

Beyond storage, using your energy smartly is key to optimising solar power. This is where devices like the MyEnergi Zappi car charger and MyEnergi immersion heater controller come into play. These smart tools are designed to help you make the most of your solar generation by automatically diverting surplus power to where it’s needed most.

The Zappi car charger allows you to charge your electric vehicle directly from your solar output, significantly reducing running costs and ensuring your car is powered by clean, renewable energy as well as being able to fast charge when needed. Similarly, the MyEnergi immersion heater controller manages your water heating , so that excess energy isn’t wasted but instead used to provide hot water for your home.

These systems increase self-consumption, which is the amount of solar energy you use yourself rather than exporting back to the grid.

Look for Value

It’s tempting to look for cheap solar panels when first considering a solar setup. However, going cheap often means sacrificing quality, performance, and long-term support. At Solarfix, we believe in offering affordable options — but never at the cost of reliability or transparency.

A well-designed, correctly installed solar system will pay for itself faster and deliver more savings over time than a budget setup that underperforms or fails early. Instead of chasing the cheapest deal, look for proper system sizing, honest advice, and long-term customer care. Your investment deserves lasting quality — that’s why Solarfix offers a 25-year performance warranty on all our solar panels. Our 5-star Google rating reflects our commitment to customer care and trusted service.

Conclusion: Utilise the Summer

With the longest days of the year and more sunlight than any other month, June is the best time to optimise your solar power setup. From installing home storage batteries and MyEnergi devices there are numerous ways to improve performance and savings this summer.
