Design Solar Arrays & Size Battery Storage
from Satellite Imagery
SiteTower lets solar contractors draw panel layouts directly on roof surfaces, auto-size inverters and battery banks, and generate application packs — all from a single 3D satellite canvas.
Purpose-Built for Solar & Backup Power Installers
Every solar project has unique roof geometry, shading constraints, and municipal requirements. SiteTower handles the complexity so you can quote with confidence.
Roof Array Designer
Draw solar panel outlines directly on the 3D roof surface. SiteTower calculates panel counts, orientation angles, and estimated daily kWh yield based on roof area and tilt.
Inverter & Battery Sizing
Based on the array design and household load profile, SiteTower recommends inverter capacity, battery storage size, and string configuration — pre-filled in your proposal.
Application Packs
Generate municipal-ready application packs with panel specs, inverter details, and connection diagrams — ready for submission.
Cable & Conduit BOM
SiteTower auto-calculates cable runs from panels to inverter and battery, conduit lengths, and connector counts — factoring in roof geometry and trench routes.
Shading Analysis
Identify potential shading from nearby trees and structures on the satellite view. SiteTower flags affected panels and adjusts yield estimates accordingly.
Proposal with System Diagram
Clients receive a branded proposal with an embedded system diagram and itemised pricing for panels, inverters, batteries, and installation labour — signable from their phone.
The Solar & Backup Power Workflow
From roof survey to final sign-off, SiteTower replaces the disconnected tools solar installers currently rely on.
Survey Roof
Search the property, outline the roof surface, and identify shading obstacles over satellite imagery.
Design Array
Draw panel layout on the roof. SiteTower auto-sizes the inverter, battery bank, and cable runs.
Quote & Propose
Generate a branded proposal with system diagram, itemised pricing, and application pack.
Manage & Close
Track change orders, log on-site adjustments, and compare quoted vs actual margin.
