Can wood-racking reduce the capital costs of small-scale solar photovoltaic systems?

Fixed-tilt mechanical racking, consisting of proprietary aluminum extrusions, can dominate the capital costs of small-scale solar photovoltaic (PV) systems. Recent design research has shown that wood-racking can decrease the capital costs of small systems by more than 75% in North America.

Is there an open source racking system for small-scale PV systems?

For small-scale PV systems racking can make up the majority of the capital expenditures. To overcome this challenge, in this study a novel parametric mobile low-cost open source racking system is designed using open source software and validated with numerical modeling.

How does a PV module work?

The device uses your existing fiberglass Werner or Louisville extension ladder. A pulley system is attached to the top of the ladder. A patented module “hook” attaches to the edge of a PV module frame and prevents lateral sliding of the module in the hook. An operator pulls the rope to raise the module.

How does a PV ladder work?

A pulley system is attached to the top of the ladder. A patented module “hook” attaches to the edge of a PV module frame and prevents lateral sliding of the module in the hook. An operator pulls the rope to raise the module. The module slides along the outward facing surface of the ladder rails.
