Mensejahterakan Rakyat dengan Listrik?

Seberapa besar konsumsi listrik mempengaruhi pertumbuhan ekonomi? Jadi kita bisa ambil 2 kesimpulan, yaitu Satu, data ini menunjukkan bahwa Indonesia sebagai negara berkembang sebaiknya memperbesar suplai listrik, karena efeknya ke pertumbuhan ekonomi hampir 4x lipat daripada negara maju. Dua, seiring dengan adanya listrik, industri dapat menghasilkan lebih banyak produk dalam negeri, sehingga ini memutar roda ekonomi […]

Cafe | What If Tenaga Surya? EP #1

Setiap bulan, seorang pemilik cafe pusing melihat besarnya tagihan PLN dari coffee maker, AC, chiller, speaker, dan lighting. Tapi di sisi lain, seorang pemilik cafe tidak bisa mematikan coffee maker begitu saja karena masih ada pesanan customer, tidak bisa mematikan AC karena customer bisa pergi karena kepanasan, dan tidak bisa mematikan chiller karena susu dan […]

Rp 0 Solar Energy Partnership Program

Solar energy (“tenaga surya” or “PLTS”) is growing worldwide. LOreal, Intel, Amazon, IKEA, Apple, and many others are using solar energy to power their operations. (See Exhibit 1.) The question is: why is solar energy not growing in Indonesia? To answer this, imagine you are a manager. One day, someone offered you solar panels costing […]

Solar Energy for Home: Case Study

A homeowner in Jakarta was interested in solar energy / PLTS, but only as his new “toy”. However, when I visited the client’s home, I noticed large electricity usage: lights, fridge, AC, water heater. Could you imagine the electricity costs? In solving this problem, Inspecro considered a PLTS system to save his costs. Before deciding […]

Hotel Solar Energy: Case Study (Pembangkit Listrik Tenaga Surya / PLTS)

A 3-star hotel consulted us Inspecro when they faced large electricity costs. Meanwhile, they could not reduce electricity usage any further: Sacrificing cooling units would make guests uncomfortable by heat. Reducing water heating would shock guests in cold evening showers. Darkening lighting would destroy the hotel appearance in the eyes of the guests. Hotel has […]

2 Types of Solar Cells: Monocrystalline vs Polycrystalline

“Monocrystalline? Polycrystalline? Which one should I go for?” Yes, these might seem overwhelming to you. Let us compare them in Performance, Cost, and Aesthetics. 1.Performance In solar cells, performance is measured in terms of efficiency. In other words, how much sun energy is converted into electricity. Here, monocrystallines are better than polycrystallines (25% vs 21%). […]

4 Reasons of Going Solar Now in Indonesia

Solar revolution is a rapid disruption. We are seeing 31% annual growth of solar.¹ Similarly, big companies worldwide are going solar. (See Exhibit 1.) For example, Apple has installed 101 MW of solar. This is enough to power around 40,000 houses. Target, a giant department store retailer in the United States, has installed twice as […]

Disruptive Innovation of Solar Energy

1. Defining Disruptive Innovation What is a disruptive innovation? Disruptive innovation is a term popularized by Clayton Christensen’s widely known book The Innovator’s Dilemma. Christensen pointed that a disruptive innovation delivers currently neglected value metrics which are different from value metrics by mainstream markets. For example, think of Tesla’s automobile value metrics: self-driving and “green”; in contrast […]

Learning Curve of Solar Energy

What is a learning curve? Basically, a learning curve describes how a process becomes more efficient as more output is produced. This could be used to predict future cost reduction of solar PV. 1. The Learning Curve Solar PV is very disruptive to the electricity grid. It is expected to be cheaper by 32.6% for […]
