Whether on or off the grid, using solar panels - or solar modules - is one of the simplest and cleanest ways to convert the sun's energy into electricity. Real Goods' legacy is directly linked to the practicality and reliability of off-grid solar panels (we sold the first off-grid solar panel in the U.S., after all). We've built off-grid solar panel systems for thousands of customers across the country since 1978, and most are still going strong decades later.
Solar panels are clean, quiet, direct, and incredibly durable, with a maintenance-free lifespan of decades. And solar has declined in price by more than half in just the last 10 years. Real Goods carries a variety of solar panels, but we're most fond of the industry-leading Canadian Solar modules and the made-in-the-USA SolarWorlds.
