(9) When you reap the harvest of your land, you shall not reap all the way to the edges of your field, or gather the gleanings of your harvest. (10) You shall not pick your vineyard bare, or gather the fallen fruit of your vineyard; you shall leave them for the poor and the stranger: I the LORD am your God.

The Torah’s model of tzedakah (social justice and support) included a variety of agricultural gifts. Grain and produce that were left or forgotten during the harvest were available for the poor to glean. The corners of the fields (pe’ah) were also designated for the poor.
In this case, the grain that is a donation is power, gleaned from a field of solar panels.
