Solar Rooftop Power Policy Changes in Karnataka

By | 2017-08-25T18:19:11+00:00 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 [...]

We at EcoSoch are always proud to own a REVA for our company. We are not only using it for our personal transport but also use it to deliver our Energy efficient Fans, LED Lights, Composting Pots to many of our customers. It had not only attracted many ogles like no other vehicle we ever [...]

Assessing Energy Needs for Solar Photo-voltaic System

By | 2018-01-17T18:20:56+00:00 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 [...]

Advantages and Disadvantages of Micro Inverters

By | 2018-01-17T18:20:56+00:00 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+00:00 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+00:00 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 [...]

What is a on-grid solar system?

By | 2018-01-17T18:20:56+00:00 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 [...]

What is “Maximum Power”?

By | 2018-01-17T18:20:57+00:00 September 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. [...]

Charge Controllers protect our batteries.

By | 2018-01-17T18:20:57+00:00 September 8th, 2014|

Our batteries are expensive components of our off-grid solar installations. So it is a good idea to protect them from over-charging and deep discharge. To do this we use charge controllers. Charge controllers sense the voltage on the battery. If it is lower than a given threshold then they disconnect the battery from the load. [...]

Batteries for Solar Panels

By | 2018-01-17T18:20:57+00:00 August 13th, 2014|

We need Deep Cycle Batteries for Solar Panels. Deep cycle batteries can withstand a deep discharge. Your car starter battery may survive a 100 deep discharges, but a high spec Deep Cycle Battery can withstand about 1200 deep discharges. Solar Panels generate low currents and charge batteries slowly. 'Solar' batteries are optimised for high battery efficiency. [...]
