Can You Add More Solar Panels to an Existing System?

Homeowners whose solar panels generate electricity that is not sufficient for their needs typically think of upgrading their existing system. Upgrading means adding solar panels to allow the system to generate more electricity.

Upgrading your solar panel system is not as simple as it may sound. It is not just a matter of adding more panels. There are several factors to consider such as the size of the panel, the available space, and the inverter capacity.

It’s ideal to use the same solar panel manufacturer for upgrades to ensure voltage capability. However, sometimes homeowners will be frustrated to find out that the original manufacturer is no longer around.

Your installer can guide you in your selection of materials needed for your solar system. If you inform your installer there is a possibility of an upgrade in the future, he or she will consider that in the choice of materials. A manufacturer that has been doing business for years could be expected to still be around in the near future. It’s likely they’ll still be in business when you decide to upgrade your system a few years down the road.

You also have to consider energy levels. A system installed about five years ago might have used 200W panels, which may be difficult to find today. Most solar panels today are over 300W, which when connected to the 200W panels will produce only up to 200W, wasting the panel’s potentials.

The other problem is the inverter. If your old inverter was not designed to handle additional panels, it can be expensive to replace.

Last, do you have extra rooftop space? And is it in a usable location, southward facing?

Upgrading your solar panel system depends on how you planned your system’s installation and how well you used a crystal ball into your future. If you have an idea about which road to take going forward, plan ahead and include the possibility of an upgrade.
