Your goal is to perform a feasibility study on solar panels installations in Nova Scotia in 2019, when Efficiency Nova Scotia offered maximum rebates - up to $10,000. By 2020, Efficiency NS lowered maximum rebate to $6,000. Exhibit 1 highlights some details on panels Exhibit 1: solar panels production estimated annual production, 8.770 26,750 4,013 a cost, CAD HST at 15% total, CAD rebate 30.763 8.775 in two-way meter, NS Power net cost, CAD 300 22.288 prospective solar installation in a townhouse Wolfville, NS. Utility rates are expected to go up: in December 2019, the Nova Scotia Utility and Review Board (UARB) approved Nova Scotia Power's three-year fuel stability plan. In 2020, 2021 and 2022, residential electricity rates will increase an average of 1.2% each year. Price per kWh was around $0.15603 in 2019. Fixed charge was $10.83 per month. All numbers are pre-tax. Exhibit 2 lists bi- monthly power by consumption the house in 2018-2019: Apr - May Exhibit 2: bi-monthly power energy used kWh Feb - Mar 4.840 2.770 Jun - Jul 1,978 Aug - Sep 629 Oct - Nov Dec-Jan Total 1,769 4,179 16.165 Efficiency Nova Scotia limits rebates by constraining installation size projected power generation should not exceed power consumption. In this case, Efficiency NS got it wrong the system is installed on the southern slope of the roof in - Wolfville, which gets more sunshine than an average community in NS, and it is more efficient.
