Dec 1, 2023 · The vacuum integrated photovoltaic (VPV) curtain wall has garnered widespread attention from scholars owing to its remarkable thermal insulation performance and power
Surabaya, East Java, Indonesia, located in the tropics, is a very suitable location for solar power generation throughout the year. This is due to its consistent sunlight exposure and tropical climate characterized by wet and dry seasons.
The climate in Surabaya is tropical, with high temperatures and humidity throughout the year, making it quite suitable for solar PV installations. However, considering the dense urban development in Surabaya city itself, large-scale solar PV installations might be challenging due to space constraints.
To foster a vibrant solar PV manufacturing ecosystem, Indonesia could explore paths to increase domestic demand for solar products. One viable approach is to focus on the rapidly growing battery manufacturing sector by providing incentives for operators to produce batteries for storing renewable energy.
Up to now, solar PV growth in Indonesia has been slow compared to various other countries in the region and, to overcome this, Indonesia’s government has set targets to increase solar PV substantially by 2030. 4 The sector, though, will face challenges in producing solar products that can compete with those of other exporting nations.
Average 5.58kWh/day in Autumn. Average 5.62kWh/day in Winter. Average 5.88kWh/day in Spring. To maximize your solar PV system's energy output in Surabaya, Indonesia (Lat/Long -7.2484, 112.7419) throughout the year, you should tilt your panels at an angle of 8° North for fixed panel installations.
Vishal Agarwal is a senior partner in McKinsey’s Singapore office; Karambir Anand is an associate partner in the Jakarta office, where Bayu Purba is a consultant; and Enrico Furnari is a consultant in the Kuala Lumpur office. Indonesia could seize the opportunity of new demand streams for solar PV by learning from other Southeast Asian countries.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
