More recently, solar PPAs have been observed in the market for SHSs, where developers take care of design, permitting, financing, installation and operation of an SHS at the customer’s rooftop or nearby plot, at little or even no cost for the customer. The developer then sells the solar PV electricity Read more…
A residential solar PV installation (SHS/PPS) typically consists of the following main components: Solar PV modulesSolar cells use sunlight to produce electricity. Solar PV modules consist of several solar cells, which can be connected in series and in parallel to achieve the desired module output power. Solar PV modules work Read more…
Successful Solar house system implementation requires collaboration among various parties. Profit, quality of life and social benefit are the driving forces for stakeholders. Key stakeholders in worldwide residential PV expansion are described in the following.

Various business models exist, mainly for grid-connected residential PV installations. A short overview is given below: Business model Description Self-consumption Residential owners produce electricity from solar PV and decrease their electricity costs; they become less reliant on utilities and can sell the excess electricity. Feed-in based System Read more…
Permitting and licensing requirements determine the eligibility of components and have to be considered for the technology assessment and system configuration. Typical requirements of regulatory frameworks are described in this section. Applicable norms and standardsSolar PV systems are electrical generators. For this reason, special attention has to be paid to Read more…
In general, the application of solar PV systems is considered to be positive, as it is a sustainable technology. Converting solar irradiation into electricity using solar PV technology does not result in air, water or ground pollution and does not endanger animal or human health.The environmental impacts are associated more Read more…
Data from national meteorological stations / institutes: » Interpolation of data due to different project location, long-term data» Programmes available with a worldwide database such as Meteonorm (depending on the region possibly with high uncertainties, sometimes correlation with satellite data)» Can be applied for energy yield simulations (yield study). Satellite Read more…
In general, solar PV modules can be installed on or in pitched roofs, or on flat roofs attached to or adjacent to buildings (ground-mounted). Prior to solar PV installation, the roof conditions have to be evaluated. The general roof conditions have to be evaluated with regard to the following aspects:1. Read more…
Following the Paris Club Agreement, India took up an ambitious plan of adding 175 GW of renewable power. Of this, solar energy (100 GW) comprises a major part of 175 GW target followed by wind (60 GW), biomass (10 GW) and small hydroelectric (5 GW). The target of 100 GW Read more…
Ideally, solar installations should be on land that is waste and barren. Such land is unequally available across States. Many Indian states have large tracts of fertile agricultural land which is now being converted to industrial land for setting up solar power plants. Such change of land use, if effected Read more…
