System 
 Engineering:
Level 1 - Basic Engineering. System Electric 
 String Sizing must be verified for each specific zip code to ensure that 
 over-voltage does not occur during low temperature conditions; severe damage 
can  occur to the inverter if not properly sized. Wind loads must be determined 
for  proper mounting hardware spacing; you must provide a basic system layout to 
our  engineering department in order to verify spacing requirements. This 
service is  provided with the basic kit purchase.
Level 2 - 
Custom  Engineering. Engineering Design is available as an option. This 
service  includes a custom design for your specific residential application 
[commercial  systems vary, call for details]; our engineers work together with 
you and/or  your installer to design a system and determine a complete BOS 
component list.  We supply site specific Electrical Schematic, CAD drawings and 
Engineering  Submittals sealed by our Florida Professional Engineer [PE] ready 
for submission  to the building department. Building Departments in other states 
may require a  local engineer review and seal at an additional cost. Our 
Engineering Department  and Installation Department will assist you with 
technical questions pertaining  to your installation. 
Level 3 - 
Custom Engineering with Balance  of System. This includes Level 2 
Custom Engineering plus the Balance of  System components; a custom tailored 
package of all components to complete the  installation [except 
 conduit].

Installation - These systems can be installed by the 
 do-it-yourselfer, however, the wiring connections should be installed by a 
 qualified electrical or solar contractor. Some rebate programs require a 
 Licensed Contractor to qualify for the rebate. Solar Direct offers installation 
 services in Florida and some other limited service areas. We can also work with 
 your choice of contractors; please call for 
 quotation.
