Solar Cost


What is the right solar tariff for India – 4.78, 4.63 or 4.34?

After an avalanche of low solar tariffs ending with a super low solar tariff of Rs 4.34/kWh in the latest reverse biddings held in Nov ’15 and Jan ’16, the market suddenly seems to be retracting.

The recent lowest discovered tariff for Karnataka was Rs 4.78/kWh, a good 10% higher than the previous lowest.

Don’t be Lakh Wise, Crore Foolish – Solar Mango’s Request to Solar Power Plant Developers

OK, so you already know the stuff that’s presented above.

You have already read or heard about the fact that there are EPCs, and there are EPCs.

Given that it is well known that there are a number of rather average EPCs out there who could seriously harm your solar power plant investment, I find it […]

Captive Solar Power Plants Becoming popular with Indian Companies

I had earlier written a blog post Captive Solar Power Plant – Is it Good for My Company? that received quite a few queries and comments, with some of them saying it is a bit too early for Indian companies for think of captive solar as the business case might not be strong enough.

I would […]

Robot Cleaning Technology for Solar Power Plants

Even in a low cost country like India, at Solar Mango we continue getting enquiries on automating O&M for solar power plants. Well, having done the math, our team is not entirely convinced that Indian solar power plants need highly automated O&M – perhaps what is optimal for our country is a mix of manual and automated maintenance.

At the same time, it […]

Softbank Too Bids at Rs 4.63/kWh for 350 MW Solar – An Analysis of the Magic Number 4.63

All right, so a few weeks back, we were all circumspect when Sun Edison bid at Rs 4.63/kWh for 350 MW solar power plant in Andhra Pradesh under the National Solar Mission.

How could this be? – we asked among ourselves. Perhaps Sun Edison is quoting an unsustainable price?, wondered many; while a humbler few said – perhaps Sun Edison knows something […]

Choosing the Right EPC for MW Scale Solar Power Plants

Who is an EPC and why does it matter?

EPC, which stands for Engineering, Procurement, Construction, refers to the company that does turnkey work for a solar power plant implementation – from design, to procurement of components to power plant construction. Some EPCs also take up maintenance work during the duration of the solar power plant.

It is said that the choice of an […]

Indian Banks and their Lending for the Solar Sector

It is a well-known cliche that banks are most willing to lend to those who…don’t need their money.

It is somewhat true for solar as well. Or at least the corollary is true – Indian banks have not exactly been keen on lending to many aspiring solar developers who however neither have a balance sheet nor […]

Quality of India’s Solar Installations Compromised in the Race to Low Tariffs

Now, this should not come as any surprise at all: Many leading personalities from the Indian solar sector feel that the quality of many solar power plant installations in the country could be suffering as developers try to execute costs at really low costs to meet the low tariffs that are resulting from many of the government auctions.

I mean, it […]

Solar Power Price in India Rs 4.2/kWh by 2020, Says KPMG, and Rs 3.69/kWh by 2025

Solar prices in India could be substantially lower than coal by 2020, according to a report by international consultancy firm KPMG.

KPMG’s report, ‘The rising sun: Disruption on the horizon’, predicts that over the next decade solar will scale up significantly, reaching a 12.5% market penetration by 2025.

On prices, KPMG predicts that by 2020 utility-scale, grid connected solar […]
