Rooftop solar photovoltaic(PV) installation in India have increased in last decade because of the flat 40 percent subsidy extended for rooftop solar PV systems (3 kWp and below) by the Indian government under the solar rooftop scheme. From the residential building owner's perspective, solar PV is competitive when it can produce electricity at a cost less than or equal grid electricity price, a condition referred as “grid parity”. For assessing grid parity of 3 kWp and 2 kWp residential solar PV system, 15 states capital and 19 major cities were considered  for the RET screen simulation by using solar isolation, utility grid tariff, system cost and other economic parameters. 3 kWp and 2 kWp rooftop solar PV with and without subsidy scenarios were considered for simulation using RETscreen software. We estimate that without subsidy no state could achieve grid parity for 2kWp rooftop solar PV plant. However with 3 kWp rooftop solar PV plant only 5 states could achieve grid parity without subsidy and with government subsidy number of states increased to 7, yet wide spread parity for residential rooftop solar PV is still not achieved. We find that high installation costs, subsidized utility grid supply to low energy consumer and financing rates are major barriers to grid parity.

Solar energy has become a matter of global attention in the past few years. This paper explores the use and benefit of solar concentrators in the solar photovoltaic (PV) systems. First, a short literature review of previous research on the usage of solar concentrators in improving solar PV system performance and reducing the cost of implementation is presented. This is followed by an overview of SolarBrane, an example of a Building Integrated photovoltaic (BIPV) system which uses an optical concentrator in the solar PV design. An optimised design of the SolarBrane is also discussed afterwards. A financial benefit study is conducted to compare the average return of investment of using the optimised SolarBrane and traditional solar PV installed in Malaysia’s environment. SolarBrane has proven to be a good alternative to achieve costeffective solar PV system. The financial analysis simulated under the new Malaysian Feed–In Tariff scheme indicates that the optimised SolarBrane could potentially reduce the initial cost of implementation by 40% and generate higher return, close to 20%, when compared to traditional solar PV systems. Key words: Solar photovoltaic; solar concentrator; solarBrane; dielectric totally internally reflecting concentrator; financial analysis

Abstract A rooftop solar photovoltaic (PV) system is an alternative electricity source that is increasingly being used for households. The potential of solar PV is location dependent that needs to be assessed before installation. This study focuses on the assessment of a solar PV potential of a site on coordinates − 29.853762°, 031.00634°, at Glenmore Crescent, Durban North, South Africa. In addition, it evaluates the performance of a 6 kW installed capacity grid-connected rooftop solar PV system to supply electricity to a household. The results, obtained from PV design and simulation tools – PV*SOL, Solargis prospect and pvPlanner, were used to analyse and establish the site and PV system technical viability. The system’s configuration is as follows: load profile - a 2-Person household with 2-children, energy consumption − 3500 kWh, system size − 6 kWp, installation type - roof mount, PV module type - c-Si - monocrystalline silicon, efficiency − 18.9%, orientation of PV modules -Azimuth 0° and Tilt 30°, inverter 95.9% (Euro efficiency), and no transformer. The results show: meteorological parameters - global horizontal irradiation (GHI) 1659.3 kWh/m2, direct normal irradiation (DNI) 1610.6 kWh/m2, air temperature 20.6°C; performance parameters - annual PV energy 8639 kWh, Specific annual yield 1403 kWh/kWp, performance ratio (PR) 74.9%, avoided CO₂ emissions 5662 kg/year, and solar fraction 42.5 %. The analysis and benchmarking of the results show that the proposed solar PV system under the current conditions is technically viable for household electrification in Durban North, South Africa.

In this work, a new modular multilevel inverter topology is introduced for a single phase grid connected Photovoltaic system. This multilevel inverter use less number of switches to generate seven levels compared to other conventional multilevel inverters. This requires only one isolated dc source to operate. So it is suitable for renewable energy application. This inverter is designed by submodule configuration; each sub module contains two switches and one DC link capacitor. The sub modules will be added to the inverter depending on number of levels. The voltage balancing of DC link capacitor is carried out by Y matrix PWM technique. Because of Y matrix PWM technique, the inverter gets a self capacitor voltage balancing ability. So there is no need of external devices required for balancing the voltage of capacitor. A PLL for grid integration and LCL filter are designed and integrated with this inverter. The simulation of proposed system is carried out by MATLAB/SIMULINK and performance of THD is monitored as per standards

The need to electrify all rural areas in India is quite compelling. However, the focus has now shifted from traditional fuel-based systems to generate electricity to renewable sources for energy generation. Though there are subsidies and policies that encourage the use of solar Photovoltaic (PV) systems, there is a need for an appropriate framework. This framework could not only offer substantial directions but it would also act as grounds to enhance rural electrification in India using solar PVs. From this perspective, the current research attempts to structure an innovative framework for solar PV system that could facilitate rural electrification in India. In particular, the district of Damoh in Madhya Pradesh was chosen as there are many villages without electricity in this district. PVsyst software was utilized to simulate the outcomes that included mathematical models and diverse components based on PV, for simulation. Three designs were developed to facilitate the simulation. These included; PVs linked with microgrid devoid of battery, individual PV systems without microgrid link and solar PVs linked to microgrid with battey. The framework for rural electrification using solar PVs will offer policy makers with insights with regards to implementing PV systems. It will also offer inputs as to the feasibility of implementing a specific system on several parameters. These would comprise of; number of households within a village, detached households etc. Nonetheless, research in future is also warranted to explore the scope for other sources of renewable energy.

With the greening of the US power grid most of the available landscape and resource investment lays with residential home owners. Historically homes were not built with green technology in mind. Roof faces do not always face south, nor are they always at optimum angles. Existing homes are often shaded by old growth trees. This paper covers decision-making tools for cost, performance, layout, and labor optimization. It also includes a case study from a residential solar PV system in suburbia Detroit, Michigan; and goes further into possible improvements to the system after initial installation and their cost effectiveness.

Abstract This paper addresses two key decisions by households to adopt rooftop solar PV systems and the length of time until the adoption. It is hypothesized that these decisions are controlled by different mechanisms and should be modelled independently. This is the first attempt to formally estimate the length of time until the adoption to the authors' knowledge. Two models are presented in this paper. The first is a mixed logit to model the respondents' intention to adopt a solar PV system, and the second is a random parameters ordered probit to estimate the length of time until the adoption. Estimation results show that the number of electrical appliances, the households' interest to harness economic benefits, and the type and characteristics of the dwelling motivate households to select a shorter duration until the adoption. Results also show that the majority (77.80%) of respondents with EVs are highly likely to adopt a rooftop system and select a shorter time duration until adoption. In addition, a significant proportion (83.23%) of respondents with high monthly electricity bills are more likely to adopt a rooftop PV system and select a shorter time duration. Results show that the average monthly electricity bill for households with a PV system has decreased by 74.04%. Reducing monthly electricity bills is a key instigator for adopting a rooftop PV system. Our results confirm the hypothesis that even if there is an intent to adopt a rooftop solar PV system, the length of time until the adoption is controlled by another mechanism.
