A new line of "plug and play" photovoltaic modules from Westinghouse Solar will help streamline solar installation on sloped and flat roofs. The "Instant Connect" modules have DC to AC current inverters built in, so wiring is less complicated.
Even with these advances, solar installation is not a job for DIYers. There are many calculations and electrical considerations involved in installing renewable systems. Proper permits and electrical code compliance are essential for safety and optimal performance.
