In the meantime, let me attempt to elaborate on answer. Your question briefly, directly and for you in English by a thesis, antithesis, synthesis, and emphasis
Best practices would be for modules modules in series to maximize V(oc). When specifical…
Alexandria:
For additional learning about photovoltaics including grid interactive, grid interactive with battery backup, and non-interactive off grid battery would suggest the following initially for your consideration -

For you, if there is electric service where you are, Deep's solution is elegant. The power "loss" with the use of batteries > power "loss" when you loose the batteries.
Alexandra, suggest learning with a solar shade analysis tool for an accurate es…
Sounds good- love ot be empowered. Wish my solar godmother would come along, But for now I guess I will read up on the micro inverter, all I know is folks have suggested I get an Epanel with an MPPT charge controller for 4 6volt batteries in series…
Alexandra: You are correct. Solar really is simple, really. No sun, no solar.
Let's start with steps - 4, and no more.
1. Find a place with good sunlight. If you wish to learn, suggest Solar Pathfinder and develop some skills and stick a pole in t…
I am novice- so most of what you said went right over my head sadly-= guess this is why if you are broke and cant hire a pro it is to complicated to put in a solar system.
Besides the area requirements - shade is the substantial issue for any photovoltaic installation. A commercial roof or a residential roof - what are the area requirements?
It is best practice to maximize the photovoltaic source circuits based on th…
wiring your solar panels in series or parallel is not going to make a difference in your performance loss due to shading. When a string of solar panels are partly shaded, the entire performance of the solar panel array will decrease. To determine ho…
If my roof gets shaded during part of the day should I wire my panels in series or parallel?

- The Outback model appears to be a good selection. Also the selection of golf cart batteries would also be a correct solution because it's a deep-cycle battery for small PV systems.
What would his thinking on the Deka Solar Battery's and it appears the Depth of Discharge (DOD) would be greater than 80%? http://www.eastpenn-deka.com/default.aspx?pageid=443
Seems more modules would be required - would like to learn about the product and would the tilt be fixed, adjustable, or tracking?
For practical safe guarding, think the applicable codes applicable to batteries would be for instance, NEC 480, 690.71 and generators and transfer switches would be NEC 445.10, 702, and because of the issues with a separately derived systems NEC 250.24 (A) (5). For batteries applicable would also be NEC 300.4 Protection Against Physical Damage. In addition, for batteries would be NEC 690.74 Battery Interconnections and 400.8 Uses Not Permitted. And the height above the batteries would be NEC 110.26 (A) (3) Height of Working Space, ... ?

- How is your solar power project going Alexandra? Any progress?
