Perovskite Solar: The Future Crystal?

Why are we talking about Perovskite Solar?

From France to Australia, breaking efficiency records in labs around the World, Perovskite Solar is the poster child for solar research today. Efficiency data from NREL tables, which represents global lab results, shows that this technology has grown most rapidly in demonstrated conversion efficiency amongst all emerging and thin-film technologies. Given that perovskite solar can be fabricated simply by spin coating, based on the principle of depositing liquids, the technology also promises to have low manufacturing costs. (more…)

Over-sizing of Solar Arrays

Over-sizing is become a popular theme in solar power plant design in India as there is an increased pressure to drive down costs in installations. Let us understand the technical benefits and dangers of over-sizing solar arrays.

1. Advantages of Oversizing Solar Arrays

1.1 Higher Yield

As all solar EPCs know, a solar array typically never generates at more than 80% of the nameplate capacity or kWp. Thus a 10 kWp solar array, at any given time in Indian conditions would rarely exceed 8 kWp. Thus if we can connect more than 10 kWp of solar panels to a system with a 10 kVA inverter, the net generation or yield of electricity will ofcourse be higher. (more…)

Net Metered Solar Plant at Indian School- Real Data

“In God we trust, everyone else bring data.”

The Indian School, New Delhi has installed a 71.2 kW net metered solar plant as previously reported by Sunkalp Energy. We had predicted that the school’s electricity bill would reduce by 65%. Now that data from the first quarter of electricity bills is out, the I am happy to share that there have been positive changes in the electricity bills after installation of solar. (more…)

Choosing the right solar module for your projects

With the growing popularity of solar energy, there has been an upsurge of system installers and manufacturers in the market. You get to hear a new name every day which, more often than not, causes confusion in the minds of buyers. Majority of buyers are not well-versed with the industry and end up basing their decision on either cost or presentation of the sellers. To address this problem, SunKalp brings to you a guide to choose your solar modules wisely- this is a technical guide for Solar EPCs. Listed below are the factors you should consider apart from cost: (more…)
