TechoSolara is a mobile application that empowers homeowners, property buyers, and sustainability planners to instantly determine the solar energy potential of any property, all before engaging engineers or commissioning surveys. Accurate, data-driven, and entirely offline.
What it does today.
Instant location analysis. Uses device GPS to immediately generate a solar potential report based on exact coordinates.
Fully offline. All calculations run on-device using solar arc mathematics. Works in remote areas with no signal.
Roof geometry. Factors in pitch and orientation; up to three roof azimuths/aspects assessed in a single calculation, with comparison and cumulative/aggregated reporting.
Shareable reports. Email formatted reports directly to installers, assessors, or planning teams.
No ads, no data sharing. Single low-cost purchase. GDPR compliant. Location data never leaves the users' device.
Built for the whole solar journey.
Homeowners assess viability before engaging someone for a survey - a time expense, even if the survey is free!
EPC assessors validate solar suitability instantly on-site.
Property buyers make informed decisions before purchase.
Local authority planners identify where solar is truly viable.
Solar engineers work out a plan for less straight-forward properties early.
Rural site assessments where network coverage is unavailable.
Local shading analysis: trees and neighbouring buildings.
Licensing model for advanced, hyper-accurate modelling.
Professional tools for EPC assessors and installers.
Phase 3: Long-range forecasting Future.
Complex roof types including hexagonal and turret forms.
Hybrid desktop and mobile platform.
Historical weather pattern integration: using long-term climate averages rather than forecasting, to give a statistically grounded multi-year generation estimate.
TechoSolara does not store, share, or transmit location data to any server. All processing happens entirely on the user's device. There are no accounts, no tracking, and no advertising. Your assessment data is yours alone.
