| Popis: | 31st European Photovoltaic Solar Energy Conference and Exhibition; 2736-2741 The present study shows that performing energy saving retrofit in air conditioning (A/C) and lighting then utilizing solar PV energy to supply the remaining load demand in grid can reach non-nuclear goal in Taiwan. An office was chosen as the demonstration site (D-1). Four energy-saving retrofits on air conditioning and lighting results in 65% energy saving. A 6 kWp solar PV system for self-consumption and without feeding energy back to grid is further installed to replace additional 20% energy to reach 85% total energy saving. The total investment for solar PV system and energy-saving retrofit is USD30,000. The net total energy saving in 20 years is USD80,000, including M&O cost. If energy-saving in air conditioning and lighting can reach 60% as D-1 did in the whole country, the nuclear power (18% electricity) can be abandomed. Several scenarios to reach non-nuclear goal are proposed. The energy storage for each 3 kWp PV unit is estimated around 4-6 kWh. Heat storage can be utilized to reduce cost dramatically as it is 10 times cheaper than battery. |
