Metro Manila, Philippines - When looking into buying a solar energy system for a home or business, you don't have to immediately go big and cover the entirety of your electric bill when considering investing for your system. That would be ideal if the budget allows, but not a lot of people know that they can always start small.

Perhaps this means generating just enough solar energy for a portion of your bill. For others, it’s a first step in building up to a full system, upgrading until the size covers your entire building’s needs. Some may even find that their energy consumption has increased over the years and the size of their existing solar energy system is not enough to cover it anymore.

If you already have a solar energy system installed and want to add additional solar panels, you'll need to consider a few things to ensure that the system works correctly:


This client started with a 15-panel system then added 20 panels to generate more clean energy and savings for their home.


Check your inverter capacity

Make sure your inverter can handle the additional power output of the new solar panels. If your current inverter has a lower capacity than the additional new panels, you may need to replace the inverter or install an additional one.

Roof space and condition

Available roof space can determine the number of additional solar panels that can be installed. Also, determine if the new solar panels will be shaded at any point during the day. Shading can significantly reduce the efficiency of the entire solar energy system, so it's crucial to ensure that the additional panels still receive maximum sunlight exposure.

Consult with a professional

It's always best to consult with a professional solar installer or electrician who can help you determine the best way to add the new solar panels to your existing system. Fortunately, at PHILERGY German Solar, our solar energy systems are modular and fully expandable. We help you find the right system by listening to your needs and sizing it based on your day consumption to make sure that it is the most efficient. We also take your target savings and available budget into consideration.

And if you are happy with how the system performs and would like to save more, we will happily reconsult, revisit your existing system and recommend the best options for you.
