Below left. This is one of two array racks we developed and built for this project. Each rack holds 12 panels. Each rack will be staggered from Solar South. One Southeast (130*), the other Southwest (226*). Our design intention is to offer at least half our panels to the Sun at any time of the day and any time of the year. A good situation for off grid systems that can only use what power they need and not what power can be harvested during Solar Noon. Where shortening autonomous night cycle has more value than all our power harvest available at the same noontime.

Below right. A sneak peek at the unpainted assembly. This array can be tilted very easily for seasonal positioning and approaching Missouri 3" hail events. We try to approach a wind load design to a wind speed that launches sizable debris, at which point survivability is based on tornado debris or a direct hit. No worries on anything less. This type of construction is exposed to weather anomalies usually in an open field 50 years minimum.

 

 Here both rack kits are loaded and ready to deliver to the site. These are the foundation prefab assemblies. Just drop them into the foundation hole and we are ready to pour concrete. Notice the base pad. This creates an earth overburden and air pressure activation to keep the array upright in any wind and any moisture saturation. Just short of one cubic yard of concrete per form, 24 cubic feet should give plenty left over to dome the top up a couple inches.

Almost ready for concrete. Looking North-East. This is the array facing 226*, for afternoon and evening sun.

The color scheme is based on natural Earth ambiance for our area and flora. All tied up. South is to the photos right. This array is skewed to face 226* for afternoon and evening power supply. The other array faces 130* for main power harvest from first morning sun to noon.

 

07/03/2013 First array legs in concrete. I like digging holes. One large hole then set in the prefab forms. Plenty of room to install grounding and position forms. Aligning is a breeze. Plenty of room to work around the base. Lower right, home and power.
