Acceptable variation in Tilt angle of solar panels at a site

By |2021-12-11T11:08:01+05:30December 11th, 2021|

In certain cases, there would be a variation in the tilt angle of solar panels at a single site itself due to unevenness of the roof, solar arrays spread across multiple roofs, curvature of barriers, uneven cement patches and to avoid shadows from adjacent solar tables and walls. In such cases, customers can raise the [...]

Inverter Clipping Losses – SolarEdge

By |2021-12-11T11:21:45+05:30December 11th, 2021|

We get questions from clients about oversizing of inverters and why we are connecting more panels to an inverter - like connecting 33 kWp of panels to a 27.6 kVA inverter. Isn't this inefficient or a wastage of solar panels? Let's say that we are using 380Wp panels. The panel is rated 380Wp under STC [...]

Can DC, AC and LA earth pits be connected together?

However, some DISCOMs insist that DC earthing pits, AC earthing pits and LA pits should be kept separate. Please have a read of Legrand's Protection against Lightning Effects guide (Page 8) which [...]

Earthing practices at EcoSoch

By |2021-10-25T15:08:30+05:30September 27th, 2021|

With highly sensitive electrical and electronic components in solar installations, the need for protection of these costly equipment against fault and lightning current is very much necessary. Electrostatic discharge can damage sensitive electronic equipment and disturb the solar power supply. Any voltage difference between individual electronic units can destroy valuable equipment. In addition, noise [...]
