Swanson's law Swanson's law Swanson's law is the observation that the price of solar photovoltaic modules tends to drop 20 percent for every doubling of cumulative shipped volume. At present rates, costs halve about every 10 years. It is named after Richard Swanson, the founder of SunPower Corporation, a solar panel manufacturer. Swanson's law has been compared to Moore's law, which predicts the growing computing power of processors. Crystalline silicon photovoltaic cell prices have fallen from $76.67 per watt in 1977 to $0.36 per watt in 2014. Plotting the module price (in $/Wp) versus time shows a dropping by 10% per year.
Prima Paint Corp. v. Flood & Conklin Manufacturing Co. decisions. Prima Paint Corp. v. Flood & Conklin Manufacturing Co. Prima Paint Corp. v. Flood & Conklin Mfg. Co., 388 U.S. 395 (1967), is a United States Supreme Court decision that established what has become known as the "separability principle" in contracts with arbitration clauses. Following an appellate court ruling a decade earlier, it reads the 1925 Federal Arbitration Act (FAA) to require that any challenges to the enforceability of such a contract first be heard by an arbitrator, not a court, unless the claim is that the clause itself is unenforceable.
