Tell us about your home
We use your address to look up your roof size, sun exposure, and local utility rates. Your information stays private. The more you share, the more accurate your estimate.
Your electricity usage
Your utility bill holds the numbers that make or break a solar proposal. Homeowners who upload their actual bill get estimates that are 40% more accurate than those who estimate — because real kWh data means a system sized exactly to your home.
Recommended. Your bill contains your exact kWh usage, rate plan, and fees — everything we need to size your system right. The closer your data is to reality, the more your proposal reflects what solar will actually save you.
Upload as a PDF or photo. We'll read the usage and amounts automatically. Multiple months = even more accuracy.
🔒 Your data stays private. Bill images are analyzed in your browser and permanently deleted within 24 hours. Account numbers are discarded immediately after parsing. We never store your full bill. Privacy Policy
Select your utility company to find your rate. Then enter how many kWh you used each month — we'll calculate the bill amount automatically.
Estimating works — but uploading your actual bill makes your proposal 40% more accurate. If you have a bill handy, switch to the "Upload" tab above.
Average monthly usage
Your Solar Economics
Estimates based on NREL PVWatts solar irradiance data, EIA state residential rate averages, and national median installed costs. Actual results will vary. Methodology & Terms
Design Your System
Tap panels to add or remove them from your roofMonthly Usage vs. Solar Production
Green above gold = solar covers your usage. Gold above green = you'll pull from the grid. Based on regional climate estimates.
Confidence Level: Tier D
We're using satellite imagery and regional estimates. Accuracy increases if you confirm roof orientation and enter your actual monthly bill.
2026 Federal Tax Credit
The 30% federal tax credit for homeowners expired December 31, 2025. Cash and Loan buyers pay full system cost. Lease and PPA providers still qualify for the federal Section 48E credit through 2027 — that savings is passed to you as lower rates.

Production estimate based on NREL PVWatts irradiance data for your region. Utility rate sourced from EIA 2024 Arizona residential average. System cost reflects $3.40/W national median (April 2026) and may vary significantly by provider, location, and system configuration. The 30% federal residential ITC expired Dec 31, 2025 — Cash and Loan figures reflect no federal credit. Lease and PPA rates shown represent starting estimates; actual rates vary by provider, credit qualification, and location. Section 48E availability through 2027 is not guaranteed and depends on provider eligibility. Battery storage costs are manufacturer estimates and do not include potential permitting, electrical upgrade, or interconnection fees.

About Kilowatt-Hours vs. Offset Percentage
Offset % sounds meaningful, but it changes with your behavior. If you buy an EV next year, your 85% offset becomes 60% — and the solar rep never told you that. Kilowatt-hours are what your utility bill actually measures. It doesn't shift.
That's why we show you kWh. It's the number on your bill that never lies.
