SPD – Working, Construction and Which voltage to select (280V or 320V)?

By |2023-06-03T11:43:05+05:30June 3rd, 2023|

Contributed by: Suraj Kumar HS 280V Vs 320V AC SPD Introduction Surge Protection Devices (SPDs) are devices that are used to protect electrical equipment against transient over voltage (TOV). TOVs often come from one of three places: the grid side (like in a load-shedding situation or switching at the local substation), or the load [...]

Understanding Electricity

By |2018-01-17T18:20:53+05:30May 25th, 2017|

What is Electricity?! Electricity is all around us, we use it in different forms throughout our day to day activities. The LED light above my head right now is converting electrical energy to light energy and heat energy. So how do we explain this phenomenon called electricity which is something we use every day but [...]

PV SYSTEM INFLUENCE ON POWER FACTOR

By |2018-01-17T18:20:54+05:30July 8th, 2016|

  When we see the ratings on AC components like transformers, power is usually rated in KVA. This is called apparent power which is the combination of active and reactive powers. Active power is the real power component of the supply that is used to do the real power (utilized power) which is measured in [...]

With the world advancing towards automation and innumerable devices making our lives progressively comfortable, the threats posed to our mother nature are being not accounted for. One of the eco friendly tasks that an individual can easily go for is to opt for solar power. There are many places where we receive plenty of sunlight, [...]

Why Solar Panels are installed at certain Angle?

By |2021-01-19T21:04:59+05:30July 4th, 2016|

A hundred and fifty million kilometers away from earth, being a nearly perfect sphere of hot plasma, sun emits around 3.86×1026 watts of energy. But only 1.74×1017 watts of energy is received by earth with the world’s yearly consumption being around 1.8×1013 watts. Harnessing this amount of energy from sun would save the earth [...]

Types of Solar On Grid inverters – Micro, String & Central

By |2018-01-17T18:20:56+05:30November 8th, 2014|

There are three type of On grid or grid-tie inverters (for details on what is a grid-tie inverter, you can refer to an earlier post  http://goo.gl/0jtWMl). They are 1. Micro inverter 2. String inverter 3. Central inverter. A Micro inverter is connected a single solar panel to  convert its generated DC current to AC current. This [...]

Effect of Temperature on Solar Panel power generation

By |2018-01-17T18:20:56+05:30November 6th, 2014|

It’s a common misconception that the solar panels generate more energy with higher temperatures and less energy with lower temperatures. So the assumption is that we have more power generated in places like Chennai than in Bangalore or for that matter in Himachal Pradesh. But in reality,   solar cells, like in all semiconductors  are [...]

Grid-tie inverters – How do they operate?

By |2017-11-20T16:21:55+05:30November 5th, 2014|

Inverters take DC power and invert it to AC power so it can be fed into the electric utility company grid. The grid tie inverter must synchronize its frequency with that of the grid (e.g. 50 or 60 Hz)  and limit the voltage to no higher than the grid voltage. A high-quality modern Grid Tie inverter [...]

What is a on-grid solar system?

By |2018-01-17T18:20:56+05:30November 3rd, 2014|

Electricity generated by a Solar Photo Voltaic (PV) system can be directly consumed by the load itself or can be  stored in a battery bank or can be sent out to the grid. A solar PV system in which the electricity generated can be sent to the grid is called an on-grid system. This type of [...]
