What is Solar OFF-GRID system ? It works by generating electricity from solar panels and using it to charge a solar battery via a charger controller. That electricity is then converted using an inverter so that it can power the home or business appliances. By saving the electricity in a solar battery, it is possible to run home with solar energy, even at night or during times when there is less sun exposure. Description : We do SITC ( Supply , Installation , Testing , Commissioning ) of Solar Off-grid / Solar Hydrid systems from capacities ranging from 1 K.watt to 300 K.watt for all applications like Industrial , Commercial and Residential. We do deal with both Ground Mounted and Roof Mounted system installations. We design battery storage capacities after proper analysis of average load , load factor , maximum instantaneous power drawn , Depth of Discharge (DOD) , State of Charge ( SOC) , Thermal properties of battery and also provide proper ventilation for gases produced from batteries . We carry out Solar system installations all across India ( from Jammu Kashmir to Tamil Nadu and from Gujarat to Assam ) . Till time we extensively worked in states like Rajasthan , Maharashtra , Gujarat , Odisha , Uttar Pradesh , Madhya Pradesh , Karnataka , Tamil Nadu , Andhra Pradesh. Proper requirement analysis (energy consumption analysis) will be done and accordingly system will be designed by using proper design tools also considering proper load bearing and wind bearing capacities w.r.t. co-ordinates. Installation , Commissioning will be carried out by trained and certified team in professional way and within stipulated time. Safer installation will be done by providing proper protection systems , by proper cabling through conduits and also by providing proper earthing and lightning arresters . Round the clock service support is available & free quarterly service visits will also be provided. IOT ( Internet of Things) enabled Inverters will be provided and complete generation data can be viewed at your fingertips in mobile application . Even troubleshooting can be done over the air ( OTA) . We use only quality material of Tier 1 brands / Globally renowned brands only and offer our best solutions at all times . Facility of AMC for Solar plants is also available. Warranty of individual components : Solar panels will be coming with 15 years of warranty and upto 25 years of performance guarantee, which states percentage efficiency of generation would be greater than 90 % at the end of 15th year and will be greater than 80% at the end of 25th year Inverters comes with a standard warranty of 2-5 years depending on capacity of inverters. Same can also be extended upto 10 years. Solar Deep Cycle batteries come with a complete warranty (without any prorate calculations) ranging from 36 months to 60 months depending on the capacity of the battery
