βThe Branchburg, N.J., facility of Pegasus Products Inc. now is 100 percent solar powered, completing the conversion in November. Spurred by the rising costs of raw materials and transportation combined with a struggling economy, the pool liner and safety cover manufacturer enlisted Vanguard Energy Partners, LLC, to install solar panels. With the help of a 30 percent government grant bestowed on companies that produce clean energy, Pegasus expects to recoup its investment within three years.β
