The use of Solar Energy to produce electricity is relatively expensive and has a high initial cost. In order to create a viable use of solar energy, we have developed SUN-UPS models which are very cost-effective and useful for multi-purpose and are easily upgradeable.

Basically Solar Modules are used in the daytime to produce electricity from the sun energy and stored in the battery for usage in the night times. We have developed 8 different models as SUN - UPS for main usage in houses, flats, common area lighting, small shops, medical shops, restaurants and in offices to be used during power cut period. The lights come ON automatically when the normal power fails and switch OFF automatically when the normal power comes back. The system is designed in such a way, the total charging is done by solar power during summer, 50% solar and 50% EB power during winter and 100% EB power in rainy days, so as to maintain the charges in the battery all the periods of the year. The products are very simple to install and requires practically no maintenance.

The life of the solar module is about 20 years and the battery life is about 3 years and the bulb life is about 5 years. The investment by commercial establishments, are also eligible for 100% depreciation in the first year itself.
