Size a PV system, estimate energy output, or find panel count from your usage, sun-hours, and performance ratio - with steps and units. The mode changes what you provide (e. , daily vs monthly load, or target kW vs usage-based sizing).
This tool estimates the optimal tilt (angle) for a fixed‐mount solar panel based on your latitude. Adjusting your panels to the right angle can increase yearly energy yield by up to 20 %.
The optimal tilt angle for solar panels typically equals your location's latitude. You can fine-tune this by subtracting 10-15 degrees for summer optimization or adding 10-15 degrees for winter.
Live calculations, validation warnings, and exportable BOM (CSV). Required Voltage at maximum power (STC). Lowest expected ambient temperature at site (for Voc cold calculation).
If the angle is too shallow or too steep, your panels won't perform at their best. Even small variations can lead to measurable differences in annual energy production.

Optimizing your solar panel angle is essential for maximizing energy production. Start by understanding tilt basics and determining your latitude. Make seasonal adjustments, tilting panels flatter in summer and steeper in winter.
Solar Struktura - A web-based SaaS tool for calculating solar elevated structure back height, individual pole heights, and pole-to-pole spacing-accurately estimated based on your desired tilt angle by simply entering your data.
Installation costs vary significantly by pitch: Steep roofs (35°+) can increase installation costs by 15-30% due to enhanced safety requirements and specialized equipment, while flat roofs may need additional tilt hardware costing $0.
