Solar PV Roof Mounting Structure Aluminum frames will be avoided for installations in coastal Solar Panels Plants installed in high dust geographies like Rajasthan and Gujrat must have the solar panels tested with relevant dust standards (Applicable standard would be IEC 60068-2-68). Fuse: Cables: The fuse shall have DIN rail mountable […]
Quality certification and standards for grid-connected rooftop solar PV systems are essential for the successful mass-scale implementation (in-order to achieve 40 GW of rooftop solar target under ‘National Solar Mission’ programme) of this technology. It is also imperative to put in place an efficient and rigorous monitoring mechanism, adherence to these standards. In-addition, a few […]
In case of third party ownership model for solar + energy storage systems, the solar + energy storage system is owned, operated, and maintained by a third-party, which provides specific solar + energy storage services according to a contractual arrangement/PPA. This process is very similar to power purchase agreements signed with independent power producers. Third-Party […]
Key Factors Affecting the Viability of Battery Energy Storage System Projects Factor Impact on Project Viability Cost of storage Battery costs, while falling, are still the most significant driver of project viability. Costs depend on the MW/MWh ratio of the battery. The terminal value at the end of the project’s economic life also has a […]
Type Description Lithium cobalt oxide (LiCoO2) The battery consists of a cobalt oxide cathode and a graphite carbon anode. The cathode has a layered structure. During discharge, lithium ions move from the anode to the cathode. The flow reverses on charge. The drawback of Li–cobalt batteries is their relatively short life span, low thermal stability, […]
Li-ion battery chemistries have the highest energy density and are considered safe. No memory or scheduled cycling is required to prolong battery life. Li-Ion batteries are used in electronic devices such as cameras, calculators, laptop computers, and mobile phones, and are increasingly being used for electric mobility. Their advantages and disadvantages are summarized in the […]
Lead acid batteries are widely used in vehicles and other applications requiring high values of load current. Its main benefits are low capital costs, maturity of technology, and efficient recycling. Advantages Disadvantages Low-cost and simple manufacture Low cost per watt-hour High specific power, capable of high discharge currents Good performance at low and high temperatures […]
ESS components are grouped according to function into battery components, components required for reliable system operation, and grid connection components. The battery system consists of the battery pack, which connects multiple cells to appropriate voltage and capacity; the battery management system (BMS); and the battery thermal management system (B-TMS). The BMS protects the cells from […]
Battery technologies for energy storage devices can be differentiated on the basis of energy density, charge and discharge (round trip) efficiency, life span, and eco-friendliness of the devices. Energy density is defined as the amount of energy that can be stored in a single system per unit volume or per unit weight. Lithium secondary batteries […]
Installation of a solar rooftop plant can yield significnt savings in your electricity bill. At firstgreen we have developed a solar calculator through which you can do the savings calculations for your solar rooftop system over period of a 25 years life. There are few factors which affect your savings. These factors include the electricity […]
