My Grid-tied System
My grid-tied system consists of only two components: the solar panels and an inverter which converts the solar panel DC electricity to the AC electricity which homes use. The system hooks up similarly to an electric water heater. The three wires from the solar panels are connected to the inverter in clearly marked places, then four wires go from the inverter to the electrical panel, attaching to a double breaker the same way a water heater does. It’s that simple and can be hooked up without calling a consultant or electrician. My electric co-op didn’t even do an inspection when they came to change my meter to a grid-tie meter, telling me anything on my side of the meter was my problem. One more reason I love living where I do.
My system has ten 300-watt solar panels giving me a 3,000-watt system. In books and articles there are chapters on how to calculate how much electricity you can generate with x number of solar panels based on a bunch of variables in any given location. Variables ranging from your latitude, daily temperatures, weather events like cloud cover, etc. A lot of math and calculations are involved which is another thing that scares people away from setting up their off-grid solar power systems.Continue reading“Using Grid-Tied PV Panels as a Starter System – Part 2, by St. Funogas”
