Solar for Electrical connections

Connecting a Single Phase Solar Inverter to a Three Phase Connection

We frequently get asked, “What happens if you connect a single phase solar inverter with a three phase net metered grid connection?”. So we at Sunkalp Energy, feel it’s important to break it down.

Technical Impact of connecting single phase inverter to a three phase connection

Connecting a three phase inverter with a three phase grid connection is always the first choice because a three phase inverter will push the same uniform amount of power down each of the phases and there is no risk of introducing any imbalance. This is almost always the preferred choice in large or industrial connections where the consumer is charged for kVA consumption and balancing each of the phases is important. (more…)

Mono PERC manufacturing

PERC: New Solar PV Technology Explained

Why are we talking about PERC Solar?

Several module manufacturers are introducing new lines of PERC solar modules which have 1% or more, higher efficiency than conventional modules. While conventional solar cells have now reached their physical efficiency limits, this new PERC architecture allows manufacturers to increase the module efficiency.

PERC Benefit

The above graphic shows how PERC solar has an edge over conventional mono modules. (more…)

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…)
