The recently released report by Rocky Mountain Institute (RMI) highlights the urgency of phasing out coal-based power plants as part of early retirement. Globally about 2000 GW of coal-based power plants are operational and the following cost of renewables has led to about 39% of coal-based power plants uncompetitive with Read more
Price of a Polysilicon plays a very important role in the costing of a solar pv module. Polysilicon prices are surprisingly high at the moment, despite the fact that polysilicon production in China has increased during the first two months of 2022. The increase in production was a little lower Read more
Proper operations and maintenance (O&M) of solar systems is important in order to ensure effective generation. One of the crucial ways in this process is to regularly remove dust and soil from solar panels, which accounts for 25 – 35% of the total O&M cost. Uncleaned solar panels result in Read more
When number of modules are connected in series and parallel combination it is known as PV array and the effective output of a PV array is determined based on the parallel/series combination of PV modules. Typically, PV array is sized based on inverter input voltage considerations. In case of a Read more
Job Overview • Work closely with clients to provide design-engineering solution for each project.• Complete interconnection drawings, single line diagrams, bid sets, construction sets, and as-built drawingsfor all solar projects.• Work with utility companies on project coordination.• Work with Operations team of the client throughout project development and implementation.• Communicate Read more
The I-V characteristics curve usually defines the PV cell performance. A combined performance of all the solar cell in a module defines a I-V characteristics of a PV module and similarly it also defines I-V characteristics of a string. The following figure shows the I-V characteristics curve, P-V characteristics curve Read more
Recently, the rupee has been devalued significantly and USD is trading above 82 rupees per USD. The depreciation of rupee is direct consequence of global as well as domestic macro-economic conditions. Controlling the rupee depreciation is not fully in the control of Government of India (GoI). Most of the solar Read more
The Solar Cells are available in the form of a single crystal cylindrical ingot. This is known as monocrystalline silicon cell. The manufacturing process of solar cell is highly energy intensive process wherein the ingot is sliced into thin wafers of about 100 – 200 µm through diamond-saw process. During Read more
Globally solar and wind project developers face the risk of regulatory uncertainties and changing policies. Typically, this business is incentive driven business and as incentives are withdrawn by government in an unexpected/sudden manner, the solar and wind companies face the burnt of these changing policy regimes. The typical incentives offered Read more
