A solar array with successive rows of photovoltaic modules angled in opposing directions forming peaks and valleys between the rows with the valleys (i.e.: lower sides of the photovoltaic module rows) being mounted close together and the peaks (i.e.: upper sides of the photovoltaic module rows) being mounted far apart to improve system aerodynamics and permit ease of access for installers. Included is a system for connecting the upper sides of the photovoltaic modules to connectors that slide on bars extending between upper and lower mounting bases and for pivot locking the lower sides of the photovoltaic modules to the lower mounting bases.
