Off grid solar system

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

Solar energy is infinitely renewable: The sun is guaranteed to be available as the largest and most reliable source of clean and free of cost energy for some billions of years to come. Solar energy is used directly on location. There are no transport costs and no appreciable conduction losses. The technology of JUNNA Solar Modules has high performance and fully developed with latest technology. Solar power systems represent quality of life and ‘environment friendly’ it protects the environment by reducing pollution, thus lowering your carbon footprint and advancing local and national energy independence and security and also it enhance the value of your real estate. 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 2 kWp photovoltaic system approximately 15 square meters in size is thus able to produce approximately an average of 270 to 320 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 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.

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 (PCU) is an integrated system consisting of a solar charge controller, inverter and a Grid 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.

Battery Bank: Batteries are specially designed for Solar systems for optimum performance, long life and high reliability.

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.
