Five tools. Every assumption visible.
These browser-based tools use public formulas and inputs you control. They do not rely on factory product tables, supplier pricing or hidden engineering assumptions.
Choose the decision in front of you.
Results appear immediately. Each tool also states what it calculates, what it leaves out and what evidence is still needed before procurement or design.
Estimate clear gap, row pitch, GCR and total field depth from transparent solar geometry.
Open tool Tilt & land useTranslate a proposed tilt and row gap into row count, panel count, height and land-use density.
Open tool Cost & ROI scenarioCalculate CAPEX, simple payback, NPV, lifecycle ROI and LCOE from assumptions you control.
Open tool Foundation screeningRank foundation families and expose the missing geotechnical evidence—without inventing pile sizes.
Open tool Wind & snow pre-checkConvert code-confirmed wind and snow inputs into preliminary pressures and tributary forces.
Open toolBuilt for transparent screening.
Calculations run locally in the browser. PVRack does not add undisclosed manufacturer data or pretend that a preliminary number is a construction specification.
Where the line is drawn.
These tools do not issue stamped calculations, product selections, final BOMs or foundation sizes. Local codes, site evidence and qualified engineering remain controlling.
