The full solar and battery design app behind Photonik. Build multi-roof layouts, model strings and shading, pick equipment, price the job, and hand a client-ready proposal to the homeowner — all in one place.
Quick calculators for the design decisions you make every day — string voltage limits, panel layouts, off-grid loads. Use them on their own for a fast check, or open Photonik Pro when a single-tool answer isn't enough.
Check string Voc and Vmp against your inverter's MPPT window at record-low and record-high site temperatures.
Sketch a single roof plane or ground area and get a panel count with row spacing and setbacks applied.
Homeowner-facing combined sizing — daily kWh, system kW, and battery kWh. Share the link when a client wants to explore the trade-offs themselves.
Enter each appliance and duty cycle to estimate summer and winter kWh/day before sizing array and battery.
Looking for a regional yield benchmark? See typical solar generation and energy-usage patterns.
The calculators above each answer one question. Photonik Pro lets you design the whole system in one place — multi-roof layouts, shading losses, equipment selection, pricing, and a proposal the homeowner can sign off on.
Open Photonik Pro →If you're a homeowner rather than an installer, start with the buying guide — it frames the same trade-offs in plain language, with a savings calculator that models your own bill.
