Find Out How Many Solar Panels Can Fit on Your Roof
Plan Your Solar System Before the Site Visit
Not sure how many solar panels can fit on your property? Use the SolarWise Roof Solar Estimator to get a quick preliminary estimate using Google Satellite imagery.
Simply search for your property, locate your roof, trace the usable roof sections, and our tool will automatically estimate the available roof area and determine how many solar panels can potentially fit based on the selected panel dimensions, proper spacing, edge clearance, and maintenance access.
How It Works
Estimate Your Solar Roof Capacity in Just a Few Steps
Find Your Property – Enter your address or use your current location to view your property through Google Satellite.
Trace Your Usable Roof – Mark the roof sections where solar panels may be installed. You can trace multiple roof sections for properties with different roof shapes.
Automatic Panel Layout – The estimator automatically finds a suitable panel direction and arranges the panels within the selected roof area while considering panel dimensions, spacing, edge clearance, and maintenance access.
See Your Estimated Solar Capacity – Instantly see the estimated number of panels, usable roof area, and potential solar system size in kWp.
Important Note
This is a preliminary roof estimate only. Satellite imagery, roof measurements, obstructions, roof slope, structural condition, shading, actual panel dimensions, fire and safety clearances, and installation requirements may affect the final number of solar panels that can be installed.
Final system design and panel layout will still be subject to SolarWise.PH site inspection, actual roof measurements, and technical assessment.

Recommended SolarWise Package
Trace your roof first
Add one or more roof sections.
Each roof section will automatically find its own best panel direction.
Search the property, then trace each usable roof face separately.

TIP:
Trace each roof face separately.
Main roof → Finish Section →
Start New Roof Section → trace extension.
Panel direction is optimized automatically,
while keeping cleaning and maintenance access space.
