Design the real roof — not a rectangle
Solar planning is a guided rooftop solar designer, linked to every customer and quote. It finds the building, reads the roof from an aerial height survey, places panels to the local rules, works out each panel's yearly output with shading, wires the system and names the grid route — every design checked against the standards of the country the house is in.
Hand it the design
You draw the building outline and the roof sections. The assistant places the panels, sizes the system to the customer's bill, picks equipment that fits, wires it, chooses the tariff and builds the priced quote — then stops so you can review. (India today; in Australia and the UK it designs from the mapped building by itself.)
It asks, it doesn't guess
Whether the customer wants backup before it adds a battery; which way to go when a choice breaks a design rule, with only the options that follow the rules. Never a guessed address or building.
Take over at any time
“Let the assistant carry on” on any design hands it over from wherever you are; Stop takes it back. At the end it sums up what it chose and why, and every choice can be changed.
- 🧭A guided design, start to finishGuided steps do the work and stop only for your decisions: the building, the roof, the obstacles, a check of the roof sections, placement and output, the battery, wiring, then the final review. Change anything by hand at any point, with undo and a full history.
- 🏠The real roof, read from the airAn aerial height survey gives each roof section its pitch, facing and size, and finds chimneys, vents and raised rooflights. No survey? Describe the roof in a click or two — hip, gable, half-hip, Dutch gable, lean-to or flat — and shared walls with neighbours are found for you.
- ✂️Obstacles confirmed before a panel goes onRoof windows and existing panels spotted in the survey photo are put to you one by one. Add no-panel zones and trees at any stage, and the design re-lays itself around them.
- 📐Placement by the rulesEvery roof section gets as many panels as the local clearances allow. If a later change breaks a rule, the affected panels are re-laid or removed automatically — with Undo.
- 🌳Shading, panel by panelEach panel's skyline is built from nearby trees, buildings and the roof itself, using the MCS shade-factor method — mirrored correctly for sites south of the equator.
- 📊Yield against the ideal roofYearly and month-by-month output from long-term irradiance records, per roof plane. Every section is compared with the site's own ideal roof, and weak sections are suggested for dropping — never removed without your say.
- 🔌Wiring, done for youStrings sized for the coldest morning and the inverter's limits, the best-fit inverter picked for you to change, and cables, fuses, isolators, surge protection and RCDs sized per country. Works with string inverters, optimisers and microinverters.
- ⚡The grid route, worked outEach design gets its connection route and forms: G98, the G99 fast tracks or a full application in Great Britain; G98/NI or G99/NI in Northern Ireland; NC6 or NC7 in Ireland; network export limits in Australia and New Zealand.
- 📄Paperwork ready for siteSingle-line diagram, string layout, bill of materials, label set and a pre-filled test sheet, plus a CAD (DXF) export and a seven-tab report with a "to confirm on site" list.
- 🔆2D and 3D on one pageSwitch views without losing your place, orbit the roof in 3D and play the sun across the day to watch shadows from trees and neighbours move over the panels.
- 💡Sized to the billStart from the customer's electricity bill: the system is sized to what they use, never above the connection's sanctioned load or a scheme's cap — or fill the roof, your choice.
- 🔋Battery and inverter, placed for youThe best-fit battery is suggested from the inverter and the customer's backup needs, and both are placed on the best wall for the wiring — shown on the map and in 3D.
- 🏷️Real equipment cataloguePanels, inverters and batteries from Wavhz's library or your own, each with its datasheet figures, priced from your price book — not a placeholder figure.
Every design in 3D: each roof section shaded by its yield against the ideal roof, the battery and inverter on the wall they will hang on, and the sun played across the day.
Designed to the rules where you install
The standard is chosen from the site's location, and every check names its clause and its basis — an MCS or scheme rule, a regulation, a manufacturer limit, industry practice or cost. Every key value can be adjusted, and each change is flagged as changed, below the standard's minimum, or to confirm locally.
Supported today, with more countries on the way — we’re working on them now. Until then, sites elsewhere are designed to international (IEC) rules.
🇬🇧 Great Britain
MCS MIS 3002 and MCS 012 · BS 7671 Section 712 · ENA G98 and G99 Issue 2 routes — G98, SGI-1/2/3, Form A1-1 or a full application, with phase imbalance up to 32 A · G100 export limitation only where the route needs it · BS 7671 labels · BS EN 62446-1 test sheet.
📍 Northern Ireland
Its own version of the UK rules: EREC G98/NI and G99/NI with notification at or before commissioning, the fast track up to 60 A per phase with export held to 16 A per phase, 16 A phase imbalance, and Northern Ireland's planning and building-control notes. MCS, BS 7671 and the 0.4 m roof-edge clearance as in Great Britain.
🇮🇪 Ireland

🇮🇳 India
International (IEC) design rules with India's scheme rules on top: PM Surya Ghar central financial assistance and state subsidies worked out on the quote · DISCOM tariffs from the state commissions' published orders · DCR modules and ALMM/BIS listings checked · GST by HSN and SAC code · the PM Surya Ghar application filled from the job.
🌍 Everywhere else
International (IEC) rules, so a site outside our covered countries still gets a standards-based layout, string design and protection — with every value open to adjust to the local code.
Every design is a preliminary design: the planner applies these standards and names each rule, and your competent person checks and signs off before installation. It does not certify an installation.
