Turn Sunlight Into Savings

A first pass from your bill and how you use power at home. You get a recommended system size, monthly savings estimate, payback timing, and a 25-year view. L2 Energy Solar confirms every figure on site before you invest.

Step 1 · Home usage

Home usage

Baseline for the model. L2 Energy Solar adjusts every figure after a site visit.

Property type
Daytime usage share

used in daylight hours

EV charging at home?
An EV you own is added to system sizing. Planning one nudges us toward EV-ready packages.
Roof / install area
Heavy shade often points to micro-inverter lines in our rules. Open roofs keep more package options.
Surplus generation
Choose "self-use only" if you have no export agreement — the system is sized to your load and surplus is valued at zero.
Battery preference

Complete every field above. Nothing is pre-filled; choose each value before you continue.

No obligation. L2 Energy Solar engineers confirm every figure on site.

Illustrative model only: no shading, outages, financing, tax, or TOU detail; utility escalation uses a flat assumed rate you can adjust. Onsite survey and L2 Energy Solar engineering replace all defaults before you invest.
