Solar PV is one of the fast-growing renewable energy in Thailand. Three sectors are contributing to solar PV installation, which are solar farms, industrial, and residential sector. However, the latter only contributes 1.39% of the cumulative capacity in 2016. By considering the lowering price of installation cost, growing affordable households, and a vast amount of solar irradiation in Thailand, it is of interest to observe the potential of the residential sector. Besides, there is a lack of study that focuses on the forecasting of residential solar PV in Thailand. Thus, this paper emphasizes on annual installation forecast of solar PV capacity in Thailand residential sector by using segmentation. This research categorizes residents into four categories, PV users with and without batteries, potential users, and rejecters, aimed to understand different types of users. An online survey of Thai residents about solar PV utilization was conducted from December 2017 to February 2018 to collect the data for the research. The results find that there is an exponential trend of increasing residential solar PV installation, followed by the reduction of payback period over time. It is forecasted about 3,511.4 MW of residential PV installation in the end of forecasting period. This research helps the decision maker to update the policies.

“…The community-shared model (also known as shared solar, community solar or community-owned) is a good opportunity for innovation and to increase the competitiveness of RE technologies. Its biggest advantage is the economy of scale to bring down the PV system costs [129,143]. This model helps communities to acquire and manage their rooftop PV systems, sharing capital and O&M costs [143,144].…”

Decarbonizing the Galapagos Islands: Techno-Economic Perspectives for the Hybrid Renewable Mini-Grid Baltra–Santa Cruz

et al. 2020

The fragile ecosystem of the Galapagos Islands is being affected by population growth, intensive tourism, the exploitation of local resources and the high consumption of imported fossil fuels. This unsustainable development model makes the provision of services such as electricity a challenge. This research investigates the hybrid renewable mini-grid Baltra-Santa Cruz, which represents 62% of the electricity generation mix of the archipelago. This study aims to support the Galapagos Zero Fossil Fuel Initiative and the Sustainable Development Goal 7 through the reduction in diesel consumption and electricity generation costs. To do so, HOMER Pro, a specialized hybrid renewable mini-grid planning tool, is used to perform several techno-economic assessments, focusing on different electricity demand scenarios. Therefore, multiple pathways are compared to identify the most reliable alternatives towards the progressive decarbonization of this hybrid system. The results indicate that installing 18.25 MWp of photovoltaic and 20.68 MWh of battery capacity could reduce the Levelized Cost of Electricity (LCOE) from 32.06 to 18.95 USc/kWh, increasing the renewable energy (RE) share from 18% to 39%. Additionally, the successful application of energy efficiency measures would even reduce the LCOE to 17.10 USc/kWh. What is more, distributed energy is considered the most attractive way to involve islanders in the energy transition process. Finally, this paper offers a comprehensive business model proposal to achieve a resilient energy supply, based on a combination of auctions and energy community models, which demands high political will, reliable and innovative regulations and social awareness about energy use.Sustainability 2020, 12, 2282 4 of 47 and implement RE projects. In addition, the Ecuadorian Electricity Master Plan (PME) 2016-2025 [44] contains the list of priority projects to increase renewable electricity generation. Moreover, those possible new partners can propose additional RE initiatives thanks to the General Regulation of the LOSPEE. This regulation [43] is based on the targets of the National Plan of Development 2017Development -2021 which prioritize RE resources exploitation to reduce the dependency of fossil fuels. What is more, new companies interested in developing RE projects can receive an income-tax-exemption for five years [46].As regards distributed generation, the photovoltaic microgeneration to electricity self-sufficiency for final consumers of electricity regulation [47] and its amendment [48] promote the installation of PV systems up to 300 kWp per user in the residential sector and below 1000 kWp per user in the commercial and industrial sectors. This regulation is not limited to rooftop PV systems. A net-metering scheme is applied to compensate electricity costs. Thanks to this mechanism, consumers are billed for their "net" electricity use and the associated costs become credits for the following months if the electricity balance is positive for users. [47].

“…As both renewable technologies have environmental life-cycle impacts significantly less than conventional energy sources, the analysis provides insights for decision-makers in Thailand and across ASEAN to consider when developing distributed generation (DG) power [13,23]. Thailand faces renewed energy security issues and this analysis can provide some insights on how to use existing energy and resources in an efficient matter to get the most energy output for energy invested in developing mini-hydro or solar PV systems [28,29].…”

Energy return on investment (EROI) of mini-hydro and solar PV systems designed for a mini-grid

2016

View full text Add to dashboard Cite

a b s t r a c tWith dramatic cost declines and performance improvements, both mini-hydropower and solar photovoltaics (PV) now serve as core options to meet the growing demand for electricity in underserved regions worldwide. We compare the net energy return on energy invested (EROI) of mini-hydropower and solar electricity using five existing mini-hydropower installations in northern Thailand with gridconnected solar PV simulations. Both assessments use a life cycle perspective to estimate the EROI. We find that distributed mini-grids with penetrations of solar PV up to 50% of annual generation can exceed the EROI of some fossil-based traditional centralized grid systems. The analysis will help planners and engineers optimize mini-grids for energy payback and utilize local resources in their design. The results suggest higher EROI ratios for mini-hydropower plants than solar PV, though mini-hydropower plants typically yield lower EROI ratios than their large-scale hydropower counterparts.
