Picture the scenario. You have just bought your family a new home. And it is beautiful. But what really attracted you to it, was the fact that it had a residential solar energy system installed.

Now from what you can tell, it seemed like a fairly small unit and on closer inspection, you find that it just runs the water heating system in the home. But you want it to do more!

So you start to wonder if more panels can be added to an already existing solar energy system?

Well, the answer is yes… and sometimes no!

Age is important

The first important factor to find out about the current solar panels is their age. If they are older than ten years, it can be very difficult to add some more panels into the system. This is mostly due to the fact that technology has moved on in the past decade. It certainly isn’t impossible but it is not something you do by yourself, no matter how good a handyman you are. The best thing to do here would be to ask a solar installer for their opinion.

If the current system is less than 10 years old, installing new panels really should not be much of a problem. But how exactly does it work?

Increasing panels

The first thing to check is the size of the inverter in the system. If it is a larger inverter then adding panels should not be too much of a problem. If it is just big enough to run the current panels then you will also need to upgrade your inverter.

But don’t forget the space available to you as well. Make sure the roof is big enough to add the panels you want and that the area where they will be added will receive optimal sunlight to make them as efficient as possible.

Consider the following

Now you might want to install panels to run your whole house and get it off the national grid but before jumping the gun you must take everything into consideration. It is for this reason that you should approach a solar company and let one of their experts come to your home to not only guide you through the process but to let you know if your expectations are viable or not.

In most cases, it would be important to get hold of the contractor that originally installed the system in the first place. This means the warranty will not be declared null and void if something goes wrong! In some cases they may not be in business anymore, then you are welcome to find another installer that will do the job for you.

Installing for the first time?

What about if you are installing a new system in your home? Many times people do start small, just using solar power for their water heating systems. Soon, however, they realize that solar is certainly the way to go and want to increase the size of their solar panels.

That’s where careful planning comes in before you do anything at all. By all means, install a smaller system but discuss with the solar panel company about expansion if necessary later down the line. They are the experts and will always have your best interests in mind.

Should you need any help with the expansion of your current system or questions about any new installations, our experts will come to your home to discuss them with you.
