Off-Grid Solar System Sizer

Three steps to a correctly sized Newpowa system — panels, charge controller, battery, mounts. Add to cart in one click per part.

Resumed your saved sizing session.

What are you powering?

Pick your closest setup — we'll pre-fill a realistic load list you can edit.

Interactive sizing needs JavaScript enabled — this wizard calculates your system in your browser. If this section looks empty, your viewer has JS off (Page Builder previews don't run scripts; the published page does). Quick links: Solar Panels · Charge Controllers · Batteries.

Build your daily load

Watts × hours per day for everything that will run off solar. Tick rows on/off, edit values and quantity, or add custom gear.

Interactive load editing loads with JavaScript. Published pages run it automatically.
Tick at least one appliance (with watts and hours above 0) to continue.

Sunlight & battery

Peak sun hours vary by region and season — slide to your worst-case month for a safer size.

Sliders and battery chemistry load with JavaScript — enabled automatically on the published page.
Peak sun hours / day4.5 h
LiFePO480% usable depth of discharge — the best long-term value
AGM Deep-Cycle50% usable DoD — lower upfront cost, shorter cycle life
Days of autonomy (no-sun buffer)1.5 days

Your recommended system

Your sized system appears here once the wizard runs (JavaScript required).
Estimates use standard off-grid engineering: 22% system loss buffer (inverter, MPPT, thermal, wiring) and a 1.25× NEC safety margin on the charge controller. Always confirm final sizing and prices at checkout with a licensed installer for large systems. Prices verified on newpowa.com; products, images, SKUs and prices shown are real Newpowa catalog data. BigCommerce adds one product per "Add to Cart" click — review your cart before checkout.
