Adding Solar Panels to an Existing System: What To Consider

Adding solar panels to your current system can improve the efficiency and performance of your solar energy setup. Before adding solar panels to an existing system, here are some things to consider.

Roof Space

Before adding panels, determine if you have enough room on your roof or the ground to accommodate the addition. Ideally, you’ll install the new panels near the existing ones to give them similar sun exposure. You should also evaluate if your home’s roof can hold the weight of additional panels. Consult a professional installer to evaluate your roof’s condition and solar capacity.

The Inverter

The inverter converts sunshine into usable electricity for your home. Determine if your current inverter can handle the power output of more panels. In some cases, upgrading to a bigger inverter may be necessary to support the increase in energy production.

Permit Requirements

Homeowners and business owners need to acquire building and electrical permits before installing solar panels. Adding panels may necessitate new permits, so familiarize yourself with legal updates and documentation requirements.

A vital aspect of the permit process involves solar PV labels (photovoltaic labels) required in most regions. These labels apply to solar equipment and electrical panels to provide safety and code compliance information. Ensure your new panels have the necessary labeling before installation.

Battery Storage

Adding solar panels to your setup often translates to increased energy production, and you might need to store excess energy for later use. If you don’t already have a battery storage system, now is an excellent time to consider installing one. Alternatively, you may need to upgrade your current battery if it cannot accommodate additional energy storage.

Net Metering

Net metering occurs when renewable energy generators, like solar panel owners, connect to the utility power grid and transfer surplus power in exchange for savings on electric bills. Upgrading your solar PV system could affect your agreement with your utility company, so review the terms and conditions. You should understand how additional solar panels will affect net metering credit rates and any fees associated with system expansion.
