Charge Your Tesla From Solar
Without a Powerwall

On NEM 3.0, PG&E pays you ~$0.05/kWh for excess solar — then charges you $0.39/kWh to charge your car overnight. SolarSmartCharge routes your surplus directly into your Tesla, automatically.

No Powerwall required. Works with SolarEdge and Tesla Solar.

How Solar EV Charging Works

No scheduling guesswork. SolarSmartCharge responds to your solar output in real time.

☀️

Live solar data — every 5 minutes

We poll your SolarEdge or Tesla Solar system every 5 minutes for real-time production data, home consumption, and grid flow.

⚡

Tesla Fleet API — no middleman

We use Tesla's official Fleet API with OAuth. Your Tesla password never touches our servers. Commands are signed with a cryptographic key your car trusts.

🎛️

Closed-loop amp control

A proportional controller calculates the exact charging amps to drive grid import toward zero. If you're exporting 500W, we ramp up ~2A. If you're importing, we ramp down. No overshooting.

🛡️

Safe by default

DC fast chargers (Supercharger / CCS) are automatically detected and never interfered with. A minimum surplus threshold prevents churn on cloudy days.

🔒

We restore your settings when done

Before the first command, we save your charge limit and amp settings. When charging ends, we restore them exactly — so your car is ready for the next trip.

📊

Savings you can see

Every session is logged. Your dashboard shows solar kWh delivered, grid kWh avoided, CO₂ savings, and estimated dollar savings based on your utility rates.

Frequently Asked Questions

Can I charge my Tesla from solar without a Powerwall?
Yes. SolarSmartCharge monitors your solar production in real time and adjusts your Tesla's charging amps to match your surplus — no Powerwall or battery storage needed. It works with Tesla Solar panels and SolarEdge inverters.
How does SolarSmartCharge work?
Every 5 minutes, SolarSmartCharge reads your solar production and home consumption. A closed-loop controller calculates the exact charging amps to drive grid import toward zero. If you're exporting surplus, it ramps up charging. If clouds roll in, it ramps down — automatically.
What solar systems does it support?
SolarSmartCharge currently works with Tesla Solar (auto-connected via your Tesla account) and SolarEdge inverters (via monitoring API key). Enphase support is coming soon.
How much can I save with solar EV charging?
On California NEM 3.0 rates, you earn ~$0.05/kWh for exporting solar but pay ~$0.39/kWh to charge from the grid. By charging from solar instead, you save $0.34 per kWh — that's over $100/month for typical Tesla drivers.
Is it safe? Will it damage my car?
SolarSmartCharge uses Tesla's official Fleet API with OAuth authentication. Your password never touches our servers. Commands are cryptographically signed. DC fast chargers are automatically detected and never interfered with.
How much does SolarSmartCharge cost?
Pro is $10/month or $79/year with a free 30-day trial — no credit card required.
