MPACT OF NEW DANISH HOURLY BASED NET METERING ON THE ACCEPTABLE SOLAR PV SYSTEM COST

摘要

The purpose of this paper is to investigate the relationship between: the size of solar PV systems; theirorientations; yearly energy consumption in households; and the acceptable break-even cost of the solar PV systems.By acceptable break-even cost, we think of the cost for a solar PV system, which will keep the solar PV businesscontinuing when supported by hourly net-metering. Measured, hourly electricity consumption from 46 households iscompared with the electricity generation from 16 different solar PV systems, with nominal power from 2 kW to 6kW. A questioner with 122 respondents reveals that approximately 30% of the population will accept a 10 yearpayback period. A 2 kW PV system can in this way cost between 4000 – 5700 €, all inclusive, when the paybackperiod must be equal to 10 years. A 6 kW PV system can in the same way cost between 9900 – 14 000 €. Operationalcost, discount rate and yearly degeneration of the solar PV system is omitted thus the results is an absolute maximum.
