Materials and Labor Variances. Solar Products, Inc., produces solar power systems for commercial buildings. Each solar power system has three solar panels. (This is the same company as the previous exercise. This exercise can be assigned independently.) For direct materials, the standard price for a solar panel is $40. A standard quantity of 3 panels is expected to be used in each solar power system produced. During January, the company purchased 1,000 panels for $38,000 and used 980 panels to produce 320 solar power systems. For direct labor, the company established a standard number of direct labor hours at 35 hours per solar power system. The standard rate is $18 per hour. A total of 10,000 direct labor hours were worked during January, at a cost of $190,000, to produce 320 solar power systems. Required: a. Calculate the materials price variance and materials quantity variance using the format shown in Figure 10.4. Clearly label each variance as favorable or unfavorable. b. Calculate the labor rate variance and labor efficiency variance using the format shown in Figure 10.6. Clearly label each variance as favorable or unfavorable. a. As shown below, the materials price variance is: As shown below, the materials quantity variance is: Incorrect Incorrect Incorrect Unfavorable Correct Actual Materials Costs = AQ' X AP panels per panel Actual Quantity at Standard Rate AOP x SP panels Standard Materials Costs (Flexible Budget) = SO X SP panels per panel X per panel $40,000 materials price variance AQ" SP 980 panels per panel Check your detail work here by reviewing the Correct/Incorrect column. materials quantity variance AQP is Check your work Incorrect AP is: Incorrect AQP X AP is: Incorrect SP is: Incorrect AQSP is: Correct Correct AQ x SP is: Incorrect SQ is: Incorrect SQ x SP is: Incorrect AQ" is: Incorrect b.
