A method of storing solar energy in the immediate vicinity of available solar energy comprising the steps of generating electrical current with the available solar energy and charging a strip of electret producing material directly with the electrical current so that the strip of material is changed into a strip of electret means that can be subsequently utilized to produce work, such as forming part of an electrostatic separator unit, whereby the available solar energy need not be transmitted in any form other than by the produced electret means.
