Net Metering in Delhi ...started to benefit residents !

Net Metering - long awaited has started to make an appearance in New Delhi, and more and more residents and buildings are expected to benefit from its use.

The utility companies are expected to buy power at INR 5.50 from the residents who can produce power from their rooftop. While the article below has the details, and mentions broad and indicative rates, perhaps it may be beneficial for residents to check the rates and installation costs themselves, by sending in an email to contact@urjaunlimited.in

The pricing for a small rooftop power pack could be as low as INR 64000 per unit. This would be sufficient for smaller loads, and to meet needs of a small family. This will not have storage as part of the solar power pack. Off Grid solar packs are ones that have battery back up built in as well, and can store some power for the night as well.

Separate energy meters installed at the household level can measure energy produced and consumed / exported into the grid, for the grid tied systems. The scheme can work in Delhi, and many residents have already expressed willingness to go in for such systems. We are helping install several such systems, and can work with other companies in this space to help install more.

The utility company benefits since they dont have to buy expensive power - at peak power rates. Some amounts of energy ( typically during day time) can be produced using solar. If residents do this, en masse, the amount of electricity required during day use gets significantly reduced.

MIT Report argues why residential rooftops are not the best place for Solar !

The MIT report talks about the subsidies being offered in the USA based on costs of installation - a flawed approach. For instance, if the benchmark cost of installation is fixed, does that define subsidies to be provided for solar. In our view thats absolutely wrong. How do you incentive efficient and cost effective installations. 

In India, for instance, the cost of grid tied installations is now dropping to about INR 65-70 per watt depending upon site location, and complexities of installation. Hence, a power plant producing about 300 KWp of rated capacity, and producing about 435000 units of electricity annually, would cost about INR 94.25 lakhs, thereby providing you with an average payback period of less than 7 years factoring in 3 % increase on prevailing electricity tariff ( average taken at INR 7.80 per Kwh - of course different states in India have different electricity tariff rates).


The report ( link attached below) essentially argues that solar energy costs more per unit of generating capacity on rooftops than on vast solar farms. Therefore if the two types receive the same cost-based subsidy then more money will be paid for less generating capacity with rooftop systems than with large utility-scale arrays.

               Why the best place for solar panels may not be on your roof ?
