Solar Power Plant Systems

MSS provides end to end roof top installation services for Solar Power plants both Off-Grid (with battery bank) and Grid-tied type (without battery bank). We undertake turnkey Solar power plant projects of 10 kW and above capacities and use high quality components to ensure maximum energy yield. Solar power plant is an excellent alternative to Diesel generator and now is almost at-par with Grid electricity prices in many parts of India.

Solar Power Plant Types:

Off-Grid System: Off-Grid Solar power plants utilize a dedicated battery bank to store excess energy which can be utilized in case of low solar intensity or during night time. The presence of Mains supply from electricity grid is not a mandatory requirement in such systems. However, in case of both Grid supply and solar energy availability, this system gives priority to FREE Solar power. This system is more suited for areas with erratic & unreliable Grid electricity supply.

On-Grid or Grid-Tied System: A Grid-tied system does not require a battery bank but the presence of Mains supply from electricity grid / Diesel generator is mandatory. As long as Grid electricity is available and Sun is shining, the appliances can be run directly on Solar power. If intensity of Sun rays is low, then some part is grid electricity is also consumed. Although this system is more cost effective than Off-grid system, but it is more suited for areas where Grid electricity supply is reliably available throughout daytime.

 

 

Grid-connected solar systems

Solar panels that harness the sun's power to generate electricity provide clean power for homes, communities and businesses, and help cut global carbon emissions.

Solar photovoltaic (pv) modules generate electricity from sunlight, which can be fed into the mains electricity supply of a building or export to the public electricity grid. Reducing the need for fossil fuel generation, the growing grid-connected solar PV sector across the globe is helping create jobs, enabling families and businesses to save money, and cut greenhouse emissions.

Key facts

• Typical cost between INR 8 Lakh and INR 10Lakh per 10 KWp for solar systems.
• Generates 0.8% of global electricity.
• PV modules use semiconductor materials to generate dc electricity from sunlight. A large area is needed to collect as much sunlight as possible, so the semiconductor is either made into thin, flat, crystalline cells, or deposited as a very thin continuous layer onto a support material. The cells are wired together and sealed into a weatherproof module, with electrical connectors added. Modern modules for grid connection usually have between 48 and 72 cells and produce dc voltages of typically 25 to 40 volts, with a rated output (see box) of between 150 and 250 Wp.
• In order to supply electricity into a mains electricity system, the dc output from the module must be converted to ac at the correct voltage and frequency. An electronic inverter is used to do this. Generally a number of PV modules are connected in series to provide a higher dc voltage to the inverter input, and sometimes several of these ‘series strings’ are connected in parallel, so that a single inverter can be used for 50 or more modules. Modern inverters are very efficient (typically 97%), and use electronic control systems to ensure that the PV array keeps working at its optimum voltage. They also incorporate safety systems as required in the country of use.
