☀️Evaluate your existing solar panel setup and inverter capacity before adding more solar panels.

☀️Residential systems in the UK are limited to 3.68kW without additional permissions like a G99 DNO.

☀️Ensure your roof can support the additional weight & has enough space without causing shading issues.

☀️Expanding your system increases energy production, reduces reliance on the grid & lowers electricity bills.

Imagine slashing your energy bills and boosting your home’s value with just a few extra solar panels. It’s an enticing thought, right? As a UK homeowner, you might be wondering if it’s possible to expand your existing solar panel setup to generate even more clean energy. The good news is, it often is! But there are a few key considerations to keep in mind.

Assessing Your Current System

Before you start adding more panels, it’s crucial to evaluate your current setup. The size of your existing solar system and the capacity of your inverter will play a significant role in determining how many additional panels you can install. If your system is already close to the maximum capacity allowed by your Distribution Network Operator (DNO), you might need to apply for permission to increase your solar system size.

Grid Permission and Inverter Compatibility

In the UK, most residential solar systems are limited to a maximum of 3.68kWp (kilowatt peak) without requiring additional permissions. If you plan to exceed this limit, you’ll need to submit a DNO application. This process can take several months, so it’s best to start early.

Additionally, adding more solar panels might necessitate upgrading your solar inverter. String inverters, which are commonly used in residential systems, are typically sized for a specific number of panels. If you add more panels, you might need a larger inverter or even a separate inverter for the new panels.

Roof Space and Panel Weight

Another factor to consider is the physical space on your roof. Solar panels weigh between 15 and 30 kg each, so you’ll need to ensure your roof can support the additional weight. It’s also important to check that there’s enough space to accommodate the new panels without causing shading issues for the existing ones.

Benefits of Adding More Panels

Expanding your solar panel array can significantly increase your energy production, potentially reducing your reliance on the National Grid and lowering your electricity bills. With the average UK household consuming around 432 kWh of solar energy per year, adding more panels can make a substantial difference.
