25 kW Solar Power Plant at Malankara Plantations Ltd

India’s first net zero office complex which meets all the Energy requirements of the Office Complex, which includes 18 tons of Air Conditioning, Computers, Lighting, Ventilation, office equipment, water pumps and a packing machine. With the installation of the Solar Power Plant, the Office Complex is now disconnected from the Gird and is functioning wholly on its self-generated Solar Power.

2.1 KW SPV Mono Crystalline Panel System for Residence

2.1 kW Solar PV Mono Crystalline Panel system, supplying 10 to 12 units (kWhr) of power for the major electrical loads  of the house which includes,  2 Laptops, 2 LCD Televisions, security system, 2 Refrigerators, 2 Mixer/Blenders, Fans, Iron box and all Lighting

15.6 KW battery less solar PV System at BPCL, Cochin

Designed, Installed and Commissioned our First Grid Feed Solar PV System at BPCL with 15.6 kW Solar PV Array capacity and 15 kW Grid feed capacity.

65 KW at Spice Village, Kumali-World first Net Zero Resort

The system not only helps to reduce the energy consumption from 306 KW to 65 KW, but also saved the noise and expense of Diesel Generators. The system supports the full load of the 56 cottages of the resort. It can generate its own electricity to meet its 100% power needs and is completely off the grid.


The Grid-Tie SPV System at RDS, Kadavanthra effectively reduces power consumption from the grid.. Erected as a fixed type structure, it also functions as the roof for the Cafeteria. The system is designed with 10.08 kWp SPV array capacity and 10 kW inverter capacity. The system is also capable of selling the power to the state grid.


The 20.4 kWp SPV system at Wonderla Holidays Pvt Ltd is uniquely designed utilizing the roof of the car parking shed for mounting the solar panels. The main benefits of the system includes reduced power consumption from grid, uninterrupted power supply for the regular connected loads, Total CO2 emission saving of 21.9 Tons/ year, Tax benefits in terms of accelerated depreciation of 80% of the total project cost in the first year itself resulting in tax saving of 23% on the project cost.


The system is designed with 34.4 kWp SPV array capacity and 34 kW inverter capacity which helps to partially cater to the energy demand of the administrative office including both power (AC, computers, motors etc) and lighting loads.  Since the 95% of the load is during the day time, a battery less grid tied system is the perfect choice.


The 21.6 kWp Grid-Tie SPV system at payyannur college, erected as a fixed type of structure, utilizes the vacant area of 324 sq. mtr. available over the roof of the college building. The system has 21.6 kWp of Thin-Film panels from GetWatt-Korea and 21 kVA inverter from SMA-Germany. Total carbon emission saving expected by setting up the proposed plant is 24.38 tons / year. 

Base Transceiver System

A large number of such sites are located in rural areas where regular power supply is scarce or does not have grid supply. The cost of energy and fuel consumption makes the operating cost of these sites considerably huge and is also hitting the profits. Many of such installation companies have installed or considering installing SPV systems across these sites to tackle the power shortage and fuel cost. However, prior to SPV system design, it essential to optimize the capacity by conducting a detailed energy audit to assess the optimum load, rectify the existing design and installation flaws for leakages and reduce the overall consumption of energy at site using passive measures.

TeamSustain offers various services for Telecom sites, which include

1.    Energy Efficiency Audit
2.    Shading analysis and estimation of power generation potential
