Fifteen tools. Every assumption visible.

Independent preliminary decision support

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.

Row spacing & GCR

Estimate clear gap, row pitch, GCR and total field depth from transparent solar geometry.

Open tool
Tilt & land use

Translate a proposed tilt and row gap into row count, panel count, height and land-use density.

Open tool
Cost & ROI scenario

Calculate CAPEX, simple payback, NPV, lifecycle ROI and LCOE from assumptions you control.

Open tool
Foundation screening

Expose missing geotechnical evidence before a foundation family is selected.

Open tool
Wind & snow pre-check

Convert code-confirmed wind and snow inputs into preliminary pressures and tributary forces.

Open tool
RFQ readiness

Score project-information completeness and generate a focused missing-data list for the next RFQ.

Open tool
Concrete quantity

Convert approved foundation dimensions into concrete volume, mass and indicative delivery loads.

Open tool
Material takeoff

Estimate modules, posts, beams, rails, clamps, fasteners and rail mass from an approved table basis.

Open tool
Transport & container

Estimate bundles per container, payload utilization and shipment count from package dimensions and weights.

Open tool
Installation schedule

Turn project quantities and crew productivity into workdays, crew-days and an indicative calendar duration.

Open tool
Thermal expansion

Estimate free member movement and movement per joint segment from length, temperature range and expansion coefficient.

Open tool
Carport capacity

Translate parking-bay and canopy geometry into module count, covered area and indicative DC capacity.

Open tool
Agrivoltaic clearance

Check simplified vertical clearance, inter-row passage and geometric GCR for agricultural equipment.

Open tool
Roof mount screening

Expose the roof evidence that must be resolved before attachment selection.

Open tool
Fixed tilt vs tracker scenario

Normalize capacity, land, yield, CAPEX, O&M and availability across low, base and high tracker cases.

Open tool

Built 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.
