Off-Grid Solar Simulator — Perma Batteries × SIGENERGY

Step 1 / 3 — Off-grid · Your needs

Size your off-grid solar system with confidence.

A few details let us size a SIGENERGY off-grid system — solar, batteries, and the backup generator that covers the rest.

Your state

Used to estimate the annual solar resource in your area.

Solar resource map

Hover a state to see its estimated solar yield. Colors group states into five sun zones.

Monthly consumption profile

Drag each bar to adjust your monthly usage — or type each month's consumption manually.

Electrical service type

Split phase 120 / 240 VAC · 60 Hz Standard U.S. residential service

SIGENERGY SigenStack system

A modular system that grows with your needs.

The SigenStack ecosystem lets you stack inverter, battery modules and an EV charger over time — without redoing the installation.

Compare with a grid connection

If your land could be connected to the grid, what would the 20-year verdict be?

Estimated grid connection cost $ Often $2,500–$50,000+ depending on the distance to the nearest utility pole or transformer (≈ $25–$50 per foot).

Off-grid system over 20 yrs ≈ $28,000

Grid connection over 20 yrs ≈ $60,000
