Designing Solar for North East India
- Posted by: Energiaa
India is a land of tremendous climate variety. From the searing heat in Ladakh to the temperate climates in the south, and the misty/rainy climate in the North east. The North Eastern part of India has long been unable to get reliable uninterrupted power supply. There are various factors leading up to this which we will not go into the details of.
Rather let us explore in this article how Solar should really be implemented in a region which is known more for its Hydro potential.
The major obstacle with installing solar in the North East is the amount of cloud cover it sees throughout the year. Misty days cause a reduction in the no. of solar days that a solar designer plans for each year. This would make it a not very ideal place for solar installation.
• Here the solution is to have larger MPPTs with more solar panels. This would mean a faster charging of the battery during daytime to compensate for the fewer hours of available sunlight. Higher capacity MPPT with more solar panels would charge the battery faster giving it the necessary units with the available sunlight so that it can be discharged during the night time when the Grid and solar both are absent.
•Storage acts as a buffer against the intermittent nature of both the renewable sources
•If the Grid is available, and your storage is charged, then you can export to the grid as well through the State installed Net Meter.
•For this you need to have a FUTURE-PROOF system which can act as the single solution for the Mini/Micro Grid’s needs.
But is only using solar energy the way to move forwards sustainably?
North East India: Land of Hydro-Solar Potential
• The North East Part of India has 40% of India’s total Hydro potential with its numerous mountain slopes
• Solar + Hydro + Storage together is the best possible solution for places which don’t have good grid connectivity as of yet
• A viable mini-micro grid from 10KW to 100KW depending on the loads can be constructed as OFF-THE-GRID renewable sources
