Inverters are electrical devices that convert the DC power generated by solar PV modules into AC power. They consist of thyristors or insulated gate bipolar transistors (IGBTs), which alternate the polarity of the DC current by means of pulse width modulation (PWM) to create a sinusoidal voltage output to match Read more…
AC cables are needed to connect the inverters’ outputs with the grid or the off-grid electrical system.On the AC side of a solar PV system, standard cables for electrical installations can be used. However, if the inverter is installed outdoors, it is important to use UV-resistant cables. Aluminium cables should Read more…
Depending on utility metering, the electricity bill shows how much electricity the owner obtains from the grid and how much electricity the solar system delivers to the grid. There is no detailed information about energy production of the solar PV system. To determine the overall energy production and behaviour of Read more…
Power generation, plant performance and, hence, project cash flow do not depend only on the chosen equipment. The main factors discussed in this section are:» system design: loss parameters, DC-to-AC ratio, monitoring and control system» maintenance: response times, scope of work aligned to local conditions, cleaning cycles» demand-driven generation versus 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…
Before designing a solar rooftop system, it is important to understand the consumption load of the house. Typically, a house has various sources of electricity and many appliances that consume it. By feeding this information into a simple online tool—solarmyroof.cseindia.org—a consumer can determine the size of the rooftop system he Read more…
Grid Connected Solar Rooftop Programme is being implemented in the Country including North Eastern States. During the year 2019-20, a total of 1.50 MW capacity has been sanctioned to Electricity Departments/DISCOMS of 2 States (i.e. 1 MW to Electricity Department of Nagaland and 0.5 MW to Electricity Department of Manipur),thereby Read more…
