Solar Photovoltic

We are one of the leading names engaged in offering our clients with Mega Watt Scale Solar Power Plants. These are designed keeping in mind the varied requirements of our clients. We make certain that all the norms are duly followed while manufacturing these, so that our clients are provided with best in class end result.

Solar Photovoltaic (SPV) Modules:

• The solar array consists of SPV modules generating the desired design power
• The array is configured as series and parallel, connected sub arrays
• The system voltage is made available to suit the inverter
• The inter-connections between panels are connected in a junction box that also contains the blocking diodes, to prevent reverse flow of power to panel in the absence of sunlight
• +vet and -vet cables are drawn from the junction box to the inverter
• The array is mounted on a specially designed common support structure

Support Structure:

• The support frame is a rugged, corrosion resistant, MS structure that needs to be anchored on to the floor or rooftop, facing the south
• The entire frame can be tilted according to the latitude of the site
• If correctly anchored, the support frame with the array installed can sustain wind speeds of up to 200 kmph
• For electrical safety, the entire frame and the array are securely earthed

Inverter:

• The inverter converts the DC supply from the solar panel to mains grade 3 phase 415 V, 50 Hz AC supply
• The capacity of the inverter is decided on the load that is to be connected to the solar system
• The output of the inverter is pure sine wave with power factor correction

Cabling and connections:

• The module outputs are terminated in terminal box and the outputs are taken out through fire retardant cables with suitable connectors that allow series parallel combination of the modules to suit the power plant requirement
• The outputs are terminated in the array junction boxes and then onto the main junction boxes. The output of the main junction boxes is given to the inverters
• The inverter AC output is connected directly to the grid or through a suitable step up transformer as the case may be

Power transformer:

• The three phase output of the Inverter is fed to the Power Transformer through LT Panel and the Power Transformer steps up the voltage to 11 KV or 33 KV as the case may be

We have in stores for our clients Roof Top Power Plants; these are offered with Photovoltaic cells. The cells are solid-state semiconductor devices, which help in conducting Solar Energy into Electricity (direct current). The cells are further connected in series or in parallel to obtain desired output and are called solar modules. When connected in series or in parallel to meet Load requirement, these cells are known as solar array.

Working Methodology:

• The Energy produced by the solar module is used to charge the Lead Acid Battery
• The Load is power-driven using the energy stored in the battery through Electronics
• The Electronic circuitry is consisting of Charge Control Unit and Inverter
• The Charge Control Unit is used to control the overcharging and deep discharging of the battery, which in turn increases the Life of the battery
• Inverter is used to convert the DC to 230 V AC with 50 Hz Frequency

Solar Power System:

• The system produces power in the day time as long as the sun light available for generating power
• Battery backup can be linked to the system for storing the generated power for the power supply in the night time
• The capacity of the battery bank will be depends on the back up period required

Features of these systems:

• 1KW to 100 KW peak AC power
• Tilted for optimal energy production
• Mounted on raised steel structure
• 10 feet clearance at lowest point
• Grid-connected
• Modular construction
• Scalable to 100 kW and beyond

Our clients are offered with Solar Street Lights. These are basically the Photovoltaic cells, which are the solid-state semiconductor devices that convert solar energy into electric energy. The solar cells of the light are tied up in series or in parallel to obtain desired output and are called solar modules. Solar modules when associated in series or in parallel to meet load requirement are called solar array. These lights are widely used in Central Govt. Departments, State Govt. Departments, NGOs, Institutes, Corporate Sectors, Industries, Resorts, Farm Houses, Bungalows, Apartments, Hotels, Schools and Hostels.

Working Methodology:

• The energy produced by the solar module is used to charge the Lead Acid Battery
• The load is motorized using the energy stored in the battery through electronics
• The electronic circuitry is consisting of Charge Control Unit and Inverter
• The Charge Control Unit is used to control the overcharging and deep discharging of the battery that helps in increasing the Life of the battery
• The Inverter is used to convert the direct energy into a high frequency supply to activate the load
• Solar Standalone Street lights:
• The Streetlight has a sensor inside the Luminaries and checks the sunshine accessible around the installed area and enables the Streetlight function in accord to that
• In general the Streetlight switches OFF at around 6.00 am
• The system does contain autonomy of 2 days i.e. even though there is no sunshine available to charge the battery then the battery takes care of the load for a maximum period of 2 days
• Effect of Environment and severe Climatic conditions:
• Solar Photovoltaic modules produce power in all types of weather
• On partly cloudy days they can produce up to 80% of their potential energy delivery; about 50% on hazel humid days and on extremely overcast days they still produce 30% of rated power
• Photovoltaic module generates more power at lower temperatures
• This is because Photovoltaic is really electronic devices and generates electricity from light, not heat
• The Solar Photovoltaic modules are the longest-lived component of a solar system
• The life of Solar Photovoltaic modules is more than 20 years and they are warranted for a period of 10 years
• These are designed to bear the rigors of the environment including arctic cold, desert heat, tropical humidity, winds in excess of 125 mph (200 kmph} and 1 inch (25mm) hail at terminal velocity
• Solar system is warranted for a period of 12 months from the date of supply and the performance warranty for Solar Photovoltaic modules is 10 years from the date of supply
• We have the team of highly qualified technical experts and the network of local sales and service dealers who offer prompt and professional service from initial consultation, system design, installation, commission and service
• We ensure that each installation meets our customers’ requirements and expectations with quality and cost effective through our commitment of service and quality

With the assistance of our team, we are engaged in offering our clients with Solar Home Lighting Systems.

How a Solar Lantern Works?

• A solar Lantern is made of three main components - the solar PV panel, the storage battery and the lamp
• The solar energy is converted to electrical energy by the SPV panel and stored in a sealed maintenance-free battery for later use during the night hours
• A single charge can operate the lamp for about 2-8hours depends on the model
• A Solar Photovoltaic Lantern is a lighting system consisting of a lamp, battery and electronics all placed in a suitable housing
• Made of metal, plastic or fiber glass and a PV module
• The battery is charged by electricity generated through the PV module
