Abstract
PLTS Atap adalah solusi berkelanjutan yang tidak hanya memenuhi kebutuhan energi, tetapi juga mendukung pengurangan emisi karbon. Pemerintah Provinsi Jawa Tengah secara aktif mendorong pengembangan PLTS atap melalui inisiatif Central Java Solar Province, kerja sama Dinas ESDM Jawa Tengah dan IESR. Komitmen ini selaras dengan target pemanfaatan EBT sebesar 21,32% pada tahun 2025, sesuai Perda Jawa Tengah No. 12 Tahun 2018 tentang Rencana Umum Energi Daerah Provinsi (RUED-P), turunan dari Perpres No. 22 Tahun 2017 tentang Rencana Umum Energi Nasional (RUEN). Serta oleh Surat Edaran Gubernur No. 671.25/000468 dan Surat Sekda No. 671/4649 yang mendorong instalasi PLTS Atap di lingkungan OPD. Penelitian ini guna mendukung pemanfaatan PLTS Atap di Gedung DPRD Kabupaten Pemalang dengan pandangan kelayakan sistem secara teknis menggunakan software utama simulasi PVsyst 7.2.6 dengan perbandingan validasi software GSA dan PVWatts - NREL dan secara ekonomi menggunakan software Excel dengan perbandingan validasi kalkulasi manual dan software RETScreen. Analisis melibatkan data intensitas radiasi matahari, temperatur rata-rata, dan ketersediaan luasan serta sudut kemiringan atap. Tilt 25° Azimuth -8° North, Tilt 25° Azimuth +172° West, serta membandingkan dengan sudut optimal Tilt 11° untuk wilayah Pemalang dan hasilnya lebih baik dengan rasio optimal produksi energi ≈ 4,9%. Beban harian rata-rata sebesar 111 kW untuk 9 jam di hari kerja (999 kWh), kapasitas terpasang 115,2 kWp, pada intensitas radiasi matahari rata-rata 3,99 Wh/m2 dapat menghasilkan energi listrik AC rata-rata tahun ke-1 ≈ 167,8 MWh dengan keluaran energi degradasi PV ≈ 0,55% per-tahun. Investasi awal sebesar ±Rp. 1,670 miliar, masa operasi 25 tahun dengan hasil performa sistem sangat baik, yang terlihat dari nilai PR sebesar 83,73% (efisiensi tinggi). Nilai ekonomi dan analisis kelayakan dengan LCC ≈ Rp. 2.378.389.046,-, COE ≈ Rp. 605,35/kWh, NPV ≈ 569.762.448,30, PI atau BCR ≈ 1,21, IRR ≈ 12,32% dan Payback Period ≈ 7 Tahun, 9 Bulan, 7 Hari. Dengan tarif PLN kategori P-2/TM adanya penghematan energi bulanan ±50%, dengan O&M sebesar 1,5% per-tahun. Pada tahun pertama dapat mengurangi emisi karbon CO2 eq Avoided dengan memberikan JaMaLi ≈ 140,93 tonCO2, pada tahun ke-25 nilai akumulasi ≈ 3,3 KtonCO2, dan Indonesia Sub-Bituminous ≈ 161,07 tonCO2, pada tahun ke-25 nilai akumulasi ≈ 3,772 KtonCO2, serta Lignite ≈ 169,46 tonCO2 pada tahun ke-25 nilai akumulasi ≈ 3,968 KtonCO2, di mana kontribusi emisi ini adanya tren menurun per-tahun ≈ 0,55%. Potensi dan performa Perencanaan PLTS Atap di Gedung DPRD Kabupaten Pemalang dikatakan layak secara teknis dan ekonomi, serta sumbangsih jumlah tidak menggunakan emisi karbon (CO2)./Rooftop PLTS is a sustainable solution that not only meets energy needs but also supports carbon emission reduction. The Central Java Provincial Government is actively encouraging the development of rooftop PLTS through the Central Java Solar Province initiative, a collaboration between the Central Java ESDM Service and IESR. This commitment is in line with the target of renewable energy utilization of 21.32% by 2025, in accordance with Central Java Regional Regulation No. 12 of 2018 concerning the Rencana Umum Energi Daerah Provinsi (RUED-P), a derivative of Presidential Regulation No. 22 of 2017 concerning the Rencana Umum Energi Nasional (RUEN). As well as by the Governor's Circular Letter No. 671.25/000468 and the Regional Secretary's Letter No. 671/4649 which encourages the installation of Rooftop PLTS within the local government offices (OPD). This study is to support the utilization of Rooftop PLTS in the Building of DPRD Pemalang Regency with a view of technical system feasibility using the main simulation software PVsyst 7.2.6 with a comparison of GSA and PVWatts - NREL software as validation and economically using Excel software with a comparison as validation using manual calculation and RETScreen software. The analysis involves data on solar radiation intensity, average temperature, and availability of area and roof slope angle. Tilt 25 ° Azimuth -8 ° North, Tilt 25 ° Azimuth +172 ° West, and comparing it with the optimal Tilt angle of 11 ° for the Pemalang area and the results are better with an optimal energy production ratio of ≈ 4.9%. Average daily load of 111 kW for 9 hours on weekdays (999 kWh), installed capacity of 115.2 kWp, at an average solar radiation intensity of 3.99 Wh/m2 can produce average AC electrical energy in the 1st year ≈ 167.8 MWh with PV degradation energy output ≈ 0.55% per year. Initial investment of ±Rp. 1.670 billion, operating period of 25 years with very good system performance results, as seen from the PR value of 83.73% (high efficiency). Economic value and feasibility analysis with LCC ≈ Rp. 2,378,389,046,-, COE ≈ Rp. 605.35/kWh, NPV ≈ 569,762,448.30, PI or BCR ≈ 1.21, IRR ≈ 12.32% and Payback Period ≈ 7 Years, 9 Months, 7 Days. With PLN category P-2/TM tariff, there is a monthly energy saving of ±50%, with O&M of 1.5% per year. In the first year, it can reduce carbon emissions CO2 eq Avoided by providing JaMaLi ≈ 140.93 tonsCO2, in the 25th year the accumulated value ≈ 3.3 KtonCO2, and Indonesia Sub-Bituminous ≈ 161.07 tonsCO2, in the 25th year the accumulated value ≈ 3.772 KtonCO2, and Lignite ≈ 169.46 tonsCO2 in the 25th year the accumulated value ≈ 3.968 KtonCO2, where the contribution of this emission has a downward trend per year ≈ 0.55%. The potential and performance of the Rooftop PLTS Planning at the Building of DPRD Pemalang Regency are said to be technically and economically feasible, and the contribution of the amount does not use carbon emissions (CO2).
