On grid solar system

Turn Your Rooftop Into a Solar Power Plant.

With Solar power System on your roof you can enjoy self-reliance by producing your own power, while also saving on huge electric bills.

The solar PV modules can be mounted on the free space available on roofs to convert the sun’s energy directly into electrical energy. The electricity produced is direct current (DC) which is converted into alternating current (AC) with a Grid Tie Inverter. The AC power can either be consumed immediately in sync with the grid power. We offers complete turnkey solutions to help you offset your energy needs with solar power so that you see a return in your bottom line. In the framework of increasing electrical energy costs they save money.

Kilowatt peak (kWp) is the measuring unit for the peak performance of a photovoltaic generator under standard test conditions. As per Indian standards a 5 kWp photovoltaic system approximately 35-40 square meters in size is thus able to produce approximately an average of 650 to 750 units of solar energy per month. The energy return time of solar power systems specifies the period of time in which a system has to be in operation in order to produce the amount of energy that was required for its manufacture. Nowadays one can assume an energy return time of three to four years which is very good value considering that a solar power system has a long economic life-time of approximately 25 to 30 years.

Typical operation
Inverters take DC power and convert it to AC power so it can be fed into the utility grid. The grid tie inverter must synchronize its frequency with the grid (e.g. 50 Hz) using a local oscillator and limit the voltage to no higher than the grid voltage. A high-quality modern GTI has a fixed unity power factor, which means its output voltage and current are perfectly lined up and output a voltage to correspond with the grid. However, supplying reactive power to the grid might be necessary to keep the voltage in the local grid inside allowed limitations. Otherwise, in a grid segment with considerable power from renewable sources voltage levels might rise too much at times of high production, i.e. around noon.
Grid-tie inverters are also designed to quickly disconnect from the grid if the utility grid goes down. The grid tie inverter will shut down to prevent the energy it transfers from harming any line workers who are sent to fix the power grid. Properly configured, a grid tie inverter enables a home owner to use solar power generation system without extensive rewiring and without batteries. If the alternative power being produced is insufficient, the deficit will be sourced from the electricity grid.

The technology of JUNNA Solar Modules has high performance and fully developed with latest technology. Solar power systems are ‘environment friendly’ it protects the environment by reducing pollution, thus lowering your carbon footprint and advancing local and national energy independence and security. it enhance the value of your real estate.
Sizing a solar system
Before you buy a system, it is very important to size your solar system properly. Sizing will depend on the load requirements in your setup. It is important to note that a Solar system is good for operating low wattage appliances like lights, fans, TV, etc. High wattage appliances like Air Conditioners and Water Heaters cannot be operated using solar PV system (in fact solar water heaters and solar air conditioners are available separately). It is very important to make sure that your system is energy efficient so that you do need a bigger sized solar system. The connected load of your setup will help you determine the size of system that you need and that in turn will drive the cost of the system.

Solar system Package consists of:

PV Modules: Junna PV modules are IEC 61215, IEC 61730 & IEC 61701 certified as per MNRE specifications. In addition, a 90% power output guarantee for ten years and 80% power output guarantee for 25 years of the module life are provided.
Solar inverter: Solar inverter (Grid-Tie) is an integrated system consisting of a MPPT charger. It provides the facility to charger the battery bank either through Solar or Grid/DG set. The PCU always gives preference to the Solar Power and will use Grid power only when the Solar Power/ Battery charger is insufficient to meet the load requirement.

Advantages & Features:

Minimal maintenance helps you take advantage of the reliable technology with PV modules typically backed by 25-30 year power-output.
We offers complete energy security, through the supply of photo voltaic systems anywhere in India. Junna solar’s high-performance solar modules and solar power systems can supply reliable, environment-friendly energy under the most diverse climatic conditions.
Compact Design & High Efficiency.
