Solar Design

In designing each customer’s solar system, LA Solar Group analyzes and considers the following items in preparing a final system design.

Your needs and requirements

(e.g., location, aesthetics, financials, goals)

Geographic location

(generally, closer to the equator, the better)


(generally, south facing is better in the northern hemisphere)

Roof area

(the more usable roof area, at least sufficient for required number of panels, facing south, the better; less area will be required if higher efficiency panels are used)

Roof condition

(roof needs to be able to support the various forces resulting from the solar panels, as well as maintain integrity during and after the mount installation process)


(clear, unobstructed access to the sun is preferred)


(usually the tilt is that of the roof but, if adjustable, the location latitude minus about 12 degrees)

Roof Type

(solar panels can be installed on almost every roof type using appropriate mounts)

Electric Main Panel sizing and circuit breaker slot(s) availability

Selecting solar panel physical size

(power output, and quantity based on production desired and cost)​

Selecting inverter quantity and type

(based on electrical characteristics)

Mounting and railing

Clearance between roof and panels

(to allow proper air circulation)

Wiring gauge and length

Roof loading

Roof obstructions

(such as chimneys or vents)

Building codes

Layout and routing of components

(panels, inverters, junction boxes, cut-off switches, wiring, grounding poles, and breakers)
