“…This helps maintain the position of the PV panels in the sun, and maximizes their efficiency. According to Farias-Rocha et al [40], studying the average solar radiation, the best position and inclination of the panels in relation to the azimuth angle is defined, in order to increase the annual solar radiation in the panels.…”

“…Farias-Rocha et al [40] argue that the incentive policy can be improved by lowering the initial costs and/or the debt interest rate, and that this can be done through government grants, tax reductions for renewable energy equipment, incentives for equipment from local sources, and establishment of credit lines for PV development. It was also reinforced that the electricity export tax greatly affects the financial viability of a project.…”

The introduction of environmental impact targets around the world has highlighted the need to adopt alternative sources of energy, which can supply the demand and mitigate the damage caused to the environment. Solar energy is one of the main sources of alternative energy, and is considered an abundant source of clean energy. However, to facilitate and encourage investors interested in the installation of photovoltaic energy systems for electricity production, it is essential to evaluate the factors that impact the economic viability of the projects. Therefore, the objective of this research is to present a systematic analytical framework, in order to identify and analyze the main factors that impact the financial feasibility of projects for the installation of photovoltaic energy plants. For this purpose, a systematic literature review was carried out, analyzing the main studies related to the topic and identifying the main factors that may financially affect investments in photovoltaic energy systems. From this review, 29 influencing factors were identified and separated into five categories, namely, location, economic, political, climatic and environmental, and technical factors. The main factors highlighted are the investment cost, power generation, operation and maintenance costs, solar radiation, lifetime, energy tariff, efficiency, electricity consumption, and interest and taxes. The results may assist policy makers, investors, researchers, and other stakeholders to identify the key factors that are being examined in the literature, and to evaluate which ones should be considered in their study to ensure the sustainable development of power generation through the solar source.

“…In Ref. [9], this study addresses the terms, conditions and effectiveness of policies reflected as the inter-annual growth in PV power production with respect to the potential realizable capacity in the country. Additionally, a life cycle cost and greenhouse gas (GHG) emission reduction analysis is presented to demonstrate the economic viability and environmental impact of implementing an on-grid residential PV installation in the country.…”

A net metering scheme based on a 3.25-kWp Photovoltaic System was setup within the facilities of a university campus located in Lima-Peru for evaluation purposes. Solar PV system output as well as energy demand were registered for the entire year 2019. The contribution of solar PV production to total electricity demand is analyzed, considering seasonal variations in both the PV production and the energy consumption within the period of one year. Total implementation cost was calculated by adding CAPEX and OPEX values for a 3.25-kWp solar PV system operating under local conditions. In this case, total investment cost for the PV systems is estimated as 4,063 US$ while annual O&M costs are estimated as 71 US$. Considering a local electricity tariff of 0.15 US$/kWh for the end user, annual cost savings is 1068 US/yr and the overall simple payback turns out to be 4.3 years. Therefore, it can be expected that potential introduction of a net metering squeme may become attractive for end users under local market conditions.

Residential solar photovoltaic (PV) system installations have become more prevalent as the installed cost has decreased over the last 10 years while system performance has improved. As these installations have increased, so too has interest in determining their economic value to a homeowner. PV installation cost estimates have typically assumed the entire cost as marginal (average cost per watt) using reported data aggregated to a state or country. This study implements a cost function that includes a fixed cost and marginal cost element to account for differences in cost structures while controlling for panel quality and specific location. The analysis uses county level installed quote data applied to estimate cost functions and apply these functions to life cycle cost analyses of the Washington DC-Maryland-Virginia (DMV) metropolitan area while incorporating state and county level differences in pricing and incentives. The estimated cost function is found to provide an installed cost estimate that is statistically different than using the traditional total average cost per watt approach for both standard and premium systems up to 9 kW and 11 kWh, respectively. The analysis finds no statistical difference in the installed cost function across counties, but clear differences in the life-cycle cost-effectiveness to a homeowner due to state policies and retail electricity prices. Absent financing, only PV systems in DC are life-cycle cost effective compared to retail electricity due to DC's strong solar renewable energy credit (SREC) market. PV can be cost effective in Maryland if financing and incentives are applied while no combination of financing or incentives makes PV cost effective in Virginia due to its lower relative electricity prices. Sensitivity analysis finds that the homeowner's assumed discount rate and the upcoming phase out of the federal investment tax credit (ITC) has a significant impact on residential PV economics.
