UPMSP High School Solar Repair study guide
UPMSP High School Solar Repair · Work through your exam, one topic at a time.
The UPMSP High School Solar Repair trade subject is a vocational paper offered under the Uttar Pradesh Board of High School and Intermediate Education (UPMSP, commonly called UP Board) at the Class 10 level. It is intended for students in vocational or trade streams who want a working, hands-on grounding in solar photovoltaic repair rather than an engineering-level design qualification. The UPMSP High School Solar Repair study guide has 10 sections and about 3,054 words.
01Solar Photovoltaic Fundamentals and System Types
This section covers Solar Photovoltaic Fundamentals and System Types. It checks whether you can explain how a PV cell converts light into DC electricity, read standard ratings, and identify the main system architectures used in small installations.
341 words, about 2 min02Solar Cell, Module and Panel Construction and Rating
Solar Cell, Module and Panel Construction and Rating covers the materials inside a module and the meaning of its label. A crystalline module stacks tempered glass, EVA encapsulant, solar cells, another EVA layer, a backsheet, a junction box and an aluminium frame.
314 words, about 2 min03Batteries, Charge Controllers and Energy Storage
Batteries, Charge Controllers and Energy Storage covers capacity, depth of discharge and charging. Capacity is quoted in ampere-hours (Ah) at a stated rate, often C10 or C20.
302 words, about 2 min04Inverters, Converters and Power Conditioning
Inverters, Converters and Power Conditioning covers conversion between DC and AC and the quality of that output. An inverter changes DC from the array or battery into AC.
314 words, about 2 min05Wiring, Cabling, Connectors, Earthing and Protection
Wiring, Cabling, Connectors, Earthing and Protection covers safe current paths and fault protection. Select cable for current-carrying capacity, voltage drop and mechanical protection.
300 words, about 2 min06Installation, Mounting and Site Assessment
Installation, Mounting and Site Assessment covers choosing a location and fixing the array safely. Check solar access from 9 a.m.
289 words, about 1 min07Fault Diagnosis, Testing and Repair Procedures
Fault Diagnosis, Testing and Repair Procedures covers finding faults without replacing good parts. Isolate the circuit safely, then work from the array to the load: visual inspection, open-circuit voltage (Voc), short-circuit current or clamp current, insulation resistance and continuity.
305 words, about 2 min08Preventive Maintenance, Cleaning and Performance Monitoring
Preventive Maintenance, Cleaning and Performance Monitoring covers keeping a system safe and productive. A preventive schedule includes visual inspection, cleaning, checking connections for discoloration or heat, torque checks, cable gland inspection, battery water topping for flooded types, and inverter filter cleaning.
294 words, about 1 min09Electrical Safety, Tools and Work Practices
Electrical Safety, Tools and Work Practices covers the hazards that make solar work different from ordinary AC work. PV arrays produce dangerous DC voltage whenever light falls on them; there is no 'off' switch at the module.
304 words, about 2 min10Solar Appliances and Small-Scale Applications
Solar Appliances and Small-Scale Applications covers lanterns, home lighting systems, street lights, pumps and small refrigerators. Each system needs a daily energy calculation in watt-hours, a battery sized for autonomy and depth of discharge, a panel sized for local peak sun hours, a controller matched to the array and battery, and a load that matches the inverter or DC voltage.
