Modules
Dimensions, power, efficiency, temperature coefficient, load, connector and warranty.
3D solar feasibility
Build a system
before a site visit.
Configure representative equipment against a scanned roof. Every output is a planning estimate, not an installer design.

04 / Household demand
Add the things that use electricity.
Use the appliance label, typical wattage, hours per use and weekly frequency to create a transparent demand estimate. This is more useful for planning than guessing from a generic household profile.
Appliances and electrical loads
For appliances that run continuously, enter their average running power and 24 hours, 7 days a week. Use the appliance energy label or a monitoring plug where available.
Catalogue architecture
Equipment is modelled as compatible components, not a single black box.
Mounting
On-roof rail, integrated roof, flat-roof ballasted, ground-mount, carport and facade systems with their own wind and access rules.
Power electronics
String, hybrid and microinverter topologies; MPPTs, DC limits, AC export and optimiser compatibility.
Storage & backup
Usable energy, charge/discharge power, chemistry, expansion, backup gateway and critical-load capability.
Site constraints
Measured roof planes, exclusions, setbacks, shadows, access, DNO pathway and evidence quality.
