Solar Rooftop Power Policy Changes in Karnataka

By | 2017-08-25T18:19:11+05:30 October 3rd, 2016|

Giving the residents of Karnataka a chance to self consume the Solar power they installed. KERC came up with few changes in their existing Solar Power policy for rooftop. The Hon’ble KERC vide order dtd: S/03/1 dtd: 19.09.2016 has issued Modification to the order 02.05.2016 in respect of determination of tariff and other norms for [...]

Types of Solar Panels

By | 2018-01-17T18:20:54+05:30 June 27th, 2016|

  Many a times when a customer tries to go for a solar installation, he asks about panels and their types and their respective lifespans. Generally, panels are manufactured using polycrystalline cells. But every time a question arises regarding thin film solar cells which are light weight and cheap. Then why aren’t we using these [...]

Site Survey & Assessment for Solar PV Installations

By | 2018-01-17T18:20:56+05:30 November 23rd, 2014|

It’s customary for a PV system integrator to do a Site survey and collect information about local conditions and issues  before any proposal is made. The information collected is then combined with the load patterns and the customer preferences to make a final proposal. There are lot of aspects in doing a site survey for [...]

Assessing Energy Needs for Solar Photo-voltaic System

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

Once you decide to go for solar installation on your rooftop, you would need to decide the type of solar rooftop PV system that you want to install. It could be off-grid roof-top or an on-grid solar rooftop PV solar system. For more details on off-grid and on-grid, please refer https://ecosoch.com/power/ For a standalone off-grid solar [...]

Solar PV String Inverters Vs Central Inverters

By | 2018-01-17T18:20:56+05:30 November 12th, 2014|

For more details on String inverters and Central Inverters, please visit the earlier post here: https://ecosoch.com/types-of-on-grid-inverters-micro-string-central/ Many-a-times it’s inherently assumed that the bigger the better and cheaper. So ideally speaking the Central Inverter architecture (small number of very large inverters ) are cheaper and have better performance that that of String Inverter Architecture (large number of [...]

Advantages and Disadvantages of Micro Inverters

By | 2018-01-17T18:20:56+05:30 November 11th, 2014|

  Solar Micro Inverters existed since the advent of the solar PV systems, but then due to high costs associated with manufacturing, it wasn’t popular until recently when a company enphase made the first commercially successful micro inverter M175 in 2008. Since then many established companies like SMA, Power-One (now ABB), Delta and other companies [...]

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

By | 2018-01-17T18:20:56+05:30 November 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 [...]

Grid-tie inverters – How do they operate?

By | 2017-11-20T16:21:55+05:30 November 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 [...]

Good news Bangaloreans! Net Metering for solar rooftop is here!

By | 2018-01-17T18:20:56+05:30 November 4th, 2014|

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+05:30 November 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 [...]
