Wind as a Second Energy Source on Exposed Sites

SARBS lists a wind mill among its products because some towers stand in a breeze that solar cannot use. Wind is a second source. It is rarely the only one, and it is a poor fit on a sheltered rooftop in a dense neighbourhood.

When it earns its mast

Coastal ground, open chars and ridgelines often have wind after sunset, which is exactly when a solar hybrid site is living on the battery. A small turbine that keeps a trickle into the DC bus can shorten the night the battery has to cover, or delay the generator start. It does not remove the need for storage. A calm night still belongs to the battery and, if you planned it, the genset.

The electrical home for that energy is the same hybrid plant: rectifier, battery and a controller that will not fight itself when grid, sun, wind and generator are all possible. Tenant monitoring still matters, because a new turbine is another thing that can fail quietly.

What to settle in the survey

Measure the wind, do not inherit it from the district average. Keep the turbine out of the radio path and out of the fall zone of the tower. Plan the maintenance climb. SARBS can look at wind beside solar during a site survey — both are on the product list. If the site is simply dark and still, spend the money on a larger battery instead.
