Does it keep earning while I'm away?

It does. Your helpers earn Volts passively, and you'll collect capped offline earnings when you return.

How do I earn faster?

Buy more buildings, purchase Boosts, and ascend to bank Sun Coins — each one permanently multiplies your output.

What does ascending (prestige) do?

Ascending resets your Volts and buildings but grants Sun Coins that boost every future run, so you grow much faster.

Can I play on my phone?

Yes, it's fully touch-friendly and works on phones, tablets and desktops with one-tap controls.

Is my progress saved?

Your progress saves automatically in your browser, so you can close the tab and pick up right where you left off.

📖 View Web Story

Solar Farm Sprawl drops you into a desert sea of solar panels and dares you to build the most sustainable volts empire on the web. It all starts with a single tap on the panel: each press mints a little Volts, and Tilt panels toward the sun to soak up volts from dawn to dusk.Spend what you earn to hire helpers like Little Technicians, Busy Technicians and eventually Cosmic Technicians. They keep working even after you stop tapping, so your Volts ticks up every single second — close the tab and you'll come back to a tidy pile of offline earnings. Stack boosts such as the "panel Festival" to multiply everything, then chase achievements that hand you a permanent edge.When growth slows, ascend to bank Sun Coins: each one you hold quietly supercharges all future runs, turning a slow start into an avalanche. It is built to play itself while you watch the counters climb, and it runs instantly in your browser on phone, tablet or desktop — no download, no sign-up. Fire up Solar Farm Sprawl, find your rhythm, and see how big an empire volts can buy.
