New Energy Sources WhatsAppQuestions: Do I need to run a ground back from the panel frames or simply ground those to a rod at the arrays? What size conduit would be recommended that take the initial fill ( 4 x 10 awg) and allow for an easy pull of another 4 in a year or so? I don''t want to go to big and waste money, but I don''t want to add more conduit later either.
New Energy Sources WhatsAppFor reference, it would cost around $50,000 to purchase the same amount of electricity from a utility provider at the national average price per kilowatt-hour increasing at 3% per year.. The bottom line. The number of solar panels you need depends more on your electricity consumption than the square footage of your house.

New Energy Sources WhatsAppWire Rating, Length and Thickness. Your solar panel kit comes with the appropriate wire size which are determined by amp capacity. The more powerful the solar system (i.e. high amp rating), the thicker the cables needed. iI it''s a 12A system, the wire has to be 12A the absolute minimum.
New Energy Sources WhatsAppHow long do solar panels last on a house? It''s up to you! Everybody''s solar system is different, but most systems can be expected to last at least 25-30 years before performance degrades significantly.. With the average payback period around 8 years, that''s more than enough time for a system to pay itself off several times over.
New Energy Sources WhatsAppSolar inverters have one core function: convert the direct current (DC) solar panels generate into an alternating current (AC) used in your home. There are two main types of home solar inverters: Microinverters attach to the back of each panel and are best for complex solar installations.. String inverters connect strings of panels in one central …
