Solar Panel Design

Solar Design

In designing each customer’s solar system, LA Solar Group analyzes and considers the following items to prepare a final system design:

Your needs and requirements

(location, aesthetics, financials, goals)

Geographic location

(the closer to the equator, the better)


(south facing is generally better in the Northern Hemisphere)

Roof area

(the more usable roof area, the better; less area will be required if higher efficiency panels are used)

Roof condition

(roof needs to be able to support the solar panels; roof also must maintain integrity during and after the mount installation process)


(with solar panel installation, clear and unobstructed access to the sun is preferred; panels should receive the maximum amount of sunlight)


(the tilt is usually that of the roof but, if adjustable, can be 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 is based on the production and cost desired)

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)
