Should I upgrade or expand my solar panel system?

Upgrading and expanding your existing solar panel system could be your answer. When it comes to solar energy, maximizing efficiency and optimizing performance are crucial.

Can you add solar panels to an existing system?

Adding solar panels to an existing system is possible, but it’s worth taking time to think it through before starting. There’s more to consider than just adding panels—you’ll want to check compatibility with the current setup, figure out if extra equipment is needed, and, of course, consider the project's budget.

How do I expand my solar PV system?

Just like solar installers size systems depending on household electricity consumption, the same is necessary for expanding an existing solar PV system. First, start by evaluating the energy bills for the house since the contractor installed the solar panel system. Next, determine if your clients have plans to increase their electricity usage.

How much does it cost to expand a solar system?

On average, homeowners can expect to pay anywhere from a few thousand to tens of thousands of dollars for this type of expansion if they are adding just solar panels and not battery storage. If a homeowner expresses interest in expanding their solar system, it's critical to know why.

Can a solar system expand if it uses a microinverter?

If the PV system uses microinverters, expanding is a bit easier. With microinverters, each solar panel has its own small inverter mounted underneath, so instead of upgrading a single string inverter, you’d just install additional microinverters on each new panel.

Should You Expand your solar power system?

Would-be solar expanders will still need to apply for new permits and a new interconnection agreement, but it won’t really affect your bottom line. But in a handful of states, the incentives for residential solar power are much worse than they used to be, and that can make the economics of expanding your solar power system much dicier.
