Start to Design

design your solar system

Solar energy is one of the cleanest energy sources available today. If more areas are utilized, it will add green to our common home.  XC Solar will do its best to build your own solar system for you, please start your design journey!


Anyone can design a solar system. First of all, you need a complete plan and then put it into action! You can do it yourself or hire us. XC Solar offers free solar design for solar kits of 5 kW or greater.

3  Step Solar Design Process

A good design follows 3 simple steps, starting with gathering all the requirements for the project!


                                                                   Step 1:  Project Assessment

1)Energy Consumption Assessment: Collect and estimate monthly energy usage (kWh) and costs for the last 12 months
2)Assess solar installation site: rooftop or property site, including size, shading, obstructions, slope, tilt, azimuth to the sun, local snow load, wind speed and exposure category
3)Assess current electrical setup: including location and size of circuit breaker boxes and existing electrical wiring
4)Qualification Review: Review local permit or utility requirements
5)Comprehensive analysis: Owner’s requirements for system location or aesthetics


                                                                                           Step 2:  System Sizes & Layout

1)Sizing a solar PV system: How many watts of solar power are needed now and how many watts of solar power will be needed in the future?
2)Estimated solar energy production scenario: how many kW or kWh will be produced using a photovoltaic system
3)Solar array site plan determination, including location of all components
4)Design layout options and preliminary engineering determination for roof or ground mounted configurations


                                                                     Step 3:  Final Plan

1)Site plan including location of all components and setbacks
2)Electrical specifications, single line diagrams - wiring diagrams, and labeling and calculations required by NEC
3)Engineering specifications for layout and installation and all necessary calculations
4)Product specifications for solar panels, inverters, installations and electrical components
5)Final purchase order and bill of materials
6)Optional: Electrical or structural engineer review and stamp as required by the building department or utility company
