Long awaited solar reforms in BESCOM have come! The Government of Karnataka has announced the Solar policy 2014-21, grid  connected solar rooftop system under net-metering basis forms an integral part of the policy. The applications are invited from BESCOM consumers who wish to install grid-connected Solar rooftop PV systems under net-metering scheme. […]

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 [...]

The image shows India's first (19.04.1975) experimental indigenous satellite, covered in solar panels. A set of solar panels like this is called an array. Each solar panel has several solar modules and each solar module has many solar cells connected in series. If you connect two voltage sources in series, they behave like a single voltage [...]

What is “Maximum Power”?

By |2018-01-17T18:20:57+05:30September 9th, 2014|

Let's take an energy source like a battery or a PV module. When you draw no current from it, the voltage at it's terminals is called it's open-circuit voltage. When you connect any electrical load to it, current flows through it and it's terminal voltage decreases because some power is  wasted by it's internal resistance. [...]
