Adding Solar Panels to an Existing System
Already gone solar but need more energy for an EV, heat pump, or other newly electrified appliance? Most of the time, you can add more solar panels to your home.
If you want to add solar panels to your existing system, the first step is to contact your original installer or another certified PV professional. During your consultation, you can determine which upgrades will be necessary to accommodate the new panels. Is it worth adding more solar panels?
But in states like California, among others, where NEM 3.0 or a net billing tariff is in place for new solar installations, homeowners locked into NEM 1.0 or NEM 2.0 can increase the benefits of their existing net metering rates with a small PV system expansion—though it can be no more than 1 kW or 10% of your existing system size.
The cost of adding extra solar panels varies based on several factors, including the number of panels, the installation's complexity, and if any other upgrades are required. Additional solar capacity typically costs between $800 and $1,600 per panel, though every project is different.
If there's enough available installation space, the cost of adding extra panels may be beneficial to maximize your long-term savings, energy independence, and environmental impact with more solar capacity.
