How teams use this section
Use these workflows to choose the right calculator path before moving into deeper analysis or formal design checks.
Panel output and daily energy screening
Estimate whether a PV concept is even in range before moving into weather data, losses, and detailed simulation.
Battery and autonomy budgeting
Relate storage, depth of discharge, and critical loads so autonomy assumptions stay grounded in real energy use.
Inverter and balance-of-system sanity checks
Use quick sizing helpers to frame inverter power, DC/AC ratio, and first-pass component assumptions.
Tilt, orientation, and available area reasoning
Connect placement and array area with expected production before refining the layout with site-specific shading tools.
Guides for this section
Published guides help explain assumptions, formulas, and the next step after a quick calculator result.
Use this guide for early PV screening when you need an order-of-magnitude kWh estimate and explicit loss assumptions before vendor curves or full shading models.
Primary tool: Solar Panel Output Estimator
Use this guide when you need a defensible first-pass storage capacity before BMS specifics, chemistry datasheets, and charge profiles are fixed.
Primary tool: Battery Bank Sizing Calculator
Use this guide when stakeholders argue about kWh/day but nobody has written down when loads actually run.
Primary tool: Load Profile Calculator
Solar & Energy FAQ
Are these tools enough for final solar design?
No. Final production and compliance decisions need climate data, equipment specifics, electrical standards, and installation constraints.
Why group production and battery tools together?
In small and off-grid systems, generation and storage assumptions are inseparable. Showing them together keeps the energy story consistent.
What should I be careful about in early solar estimates?
Be explicit about load profile, losses, seasonal variation, autonomy target, and whether your estimate is daily, monthly, or annual.
