Solar Panels vs. EV Charger: Which Home Upgrade Should You Do First?

If you own an electric vehicle and are considering solar panels — or if you have solar and are thinking about going electric — you’ve probably wondered: which should I do first? The honest answer depends on your situation, but there’s a clear logic to the optimal sequence.

The Case for EV Charger First

If you already own an EV (or are about to buy one), installing a Level 2 home charger is an immediate quality-of-life upgrade. You’ll go from a slow 120V trickle charge (adding roughly 4–5 miles of range per hour) to a robust 240V Level 2 charge (adding 20–30 miles per hour). For most EV owners, this is transformative. The cost is relatively modest — typically $600–$1,500 all-in — and you may qualify for the federal 30C tax credit. Starting here gives you the infrastructure you need right away, and when you add solar later, your panels will directly offset the electricity you’re using to charge your car.

The Case for Solar First

If you don’t yet own an EV but are planning to go electric, installing solar first has a compelling financial logic. Solar panels immediately start offsetting your existing electricity bill, generating a positive return from day one. By the time you buy your EV and install a charger, your solar system will be sized and ready to handle the additional load — potentially allowing you to drive on sunshine at near-zero marginal cost.

The Best Answer: Do Both Together

If your budget allows, doing both at the same time is often the smartest move. Many solar installers also handle EV charger installation, and bundling the work can save on labor costs. More importantly, you can size your solar system to account for your EV’s charging needs from the start, rather than retrofitting later. You’ll also only need to go through the permitting process once.

The Tax Credit Angle

Both upgrades come with federal tax incentives. Solar qualifies for the 30% Section 25D Residential Clean Energy Credit with no dollar cap. An EV charger may qualify for the Section 30C credit (up to $1,000) if your home is in a qualifying census tract. Doing both in the same tax year means you can claim both credits on a single return.
