There is no long-term percentage in installing a wind system in a poor site. You may see a short term profit, but a customer that gets poor production is a long term problem.
Many small wind systems do, indeed, perform as advertised. When installed in a marginal site, however, the results are disasterous. The internet (and now the legal system) is filled with complaints from customers claiming that a wind turbine is flawed because it’s not producing what the manufacturer or dealer claims. In most cases, the problem is inadequate wind resource.
