Presented by Gerry Imdieke
We have as much solar energy as Florida or Houston Texas 4.6 hours per day Panels produce more when cold
Green is popular We are seeing panels installed in area Mn. Dept. of Labor and Industry ruled PV panels are electrical equipment that must follow same rules as other wiring.
Licensed electrician working for an electrical contractor Homeowner wiring own residence Some municipalities might have different rules Must be wired to code & inspected
Battery systems – more cost and maintenance Location critical Snow can be issue
Stand alone- usually charge battery Great for locations where hard to receive grid power May have the best payback Grid connected Tied to grid can sell excess back to utility Power not available during outage Grid connected with battery backup Have storage and power in outage
Tracking – follows the sun % more efficient % increase in cost
One credit 16 hour course Offered as elective to electrical students Installers Homeowners Two 8 hour modules Module 1 – Wiring requirements Module 2 – Installation, efficiency, payback, design May be used for cont. ed. Workshops etc. Installers homeoweners
This course covers the installation of photovoltaic (PV) solar panels & equipment. Topics include principals of operation, payback, safety issues, system sizing and placement, with the principal focus being wiring of the units so they are in compliance with the National Electrical Code.
Min. State Community & Technical College (M State) Required Text:National Electrical Code 2008 Publisher NFPA Tentative Course Schedule Lecture 1:Introduction – principles of operation, basic theory, terminology Lecture2:Types of Systems – grid connected – stand alone tax credits, rebates, payback Lecture 3:License requirements – panel sizing NABCEP Certification Lecture 4:Test Lecture 5:Panel location, mounting systems, snow issues Lecture 6:Additional sources of Information, safety concerns
This course covers the principals of operation, safety issues, and wiring of photovoltaic (PV) solar panels so they are in compliance with the National Electrical Code. Panel, conductor, disconnect, and system sizing will be covered. Article 690 and other relevant articles of the National Electrical Code will be discussed.
Text: National Electrical Code 2008 edition Competencies: Describe safety issues Describe principals of operation Calculate conductor size and type Calculate overcurrent protection Describe specifications and placement of panels & disconnects Size panels, inverters, and batteries Describe grounding requirements
This course is an introduction to the different types of photovoltaic (PV) solar panel systems. Topics includes advantages and disadvantages of specific systems, payback, safety issues, installation requirements and principals of operation.
Text: handouts Competencies: Describe principals of operation Recognize advantages and disadvantages of different systems Calculate payback Describe factors affecting panel placement Recognize safety concerns Describe battery types

Cost of electricity Cost will be going up Systems poor grid access may be good Installation cost Varies with type of system and placement Amount of sun exposure Rebates Tax credits Power Co. rebates Great River Energy Coops Minn. Power
8 to 10 dollar per watt installed complete 2KW system $16,000 May have up to $10,000 in rebates and tax credits 10 year payback at current rates Without credits 20+ years
