HOW IT WORKS

Simple inputs. Useful preliminary guidance.

Tell us about your usage

Enter either your annual kWh usage or your average monthly electric bill.

Describe the property

We account for location, roof type, shade, and available installation space.

Review your estimate

SOLAR QUESTIONNAIRE

Build your preliminary estimate

Results are planning estimates only and should be verified using utility data, site measurements, equipment selections, and local permitting requirements.

Step 1 of 5 20%

ENERGY USE

How much electricity do you use?

Annual kWh from a utility bill is the most accurate option.

Choose an input method

Annual electricity usage

kWh/year

Often shown on your utility account or annual usage chart.

Estimated blended utility rate

Dollars per kWh, used only when estimating usage from a bill.

Desired solar offset

PROPERTY

Where will the system be installed?

Location and roof conditions affect annual solar production.

ZIP code

Property type

Roof type

Roof shading

Estimated usable roof space

FUTURE LOADS

Will your electricity use increase?

Future electric vehicles, HVAC, pools, and appliances can materially change system sizing.

Electric vehicle Adds approximately 3,500 kWh/year Heat pump HVAC Adds approximately 2,500 kWh/year Pool or spa equipment Adds approximately 1,800 kWh/year Heat pump water heater Adds approximately 1,200 kWh/year ADU or home addition Adds approximately 3,000 kWh/year No expected increase Keep the estimate near current usage

Other expected annual usage increase

kWh/year

EQUIPMENT PREFERENCES

Choose the assumptions for your estimate.

These can be adjusted later after a proper site and utility review.

Solar panel wattage

Annual production factor Southern California commonly begins near the middle or upper range before site adjustments.

Battery goal

Desired backup duration
