Founded in 1978, Real Goods is the original purveyor of off-grid living supplies. Envisioned as a one-stop-shop to meet all the needs of remote homesteaders, the store began with the sale of the first ever retail solar panel in the United States. In 1982 Real Goods published the Solar Living Sourcebook, the definitive resource for off-the-grid living, renewable energy, green building, homesteading, and all things sustainable. Since then over 700,000 copies have been sold in 44 English-speaking countries.
