Solar Power Plant

Deepa's offer of a Great Green Living which feels Great!!!

Solar power plant is based on the conversion of sunlight into electricity, either directly usingphotovoltaic(PV) and tracking systems to focus a large area of sunlight into a small beam.Photovoltaic converts light into electric current using the photoelectric effect.

The term off-grid refers to not being connected to a grid, mainly used in terms of not being connected to the main or national electrical grid. In electricity, off-grid can be stand-alone systems (SHS) or mini-grids typically to provide a smaller community with electricity. Off-grid electrification is an approach to access electricity used in countries and areas with little access to electricity, due to scattered or distant population. In situations where grid parity has been reached, it becomes cheaper to generate one's own electricity rather than purchasing it from the grid.

Check out for some of our solar PV installations. We have installed off-grid solar power generating systems ranging from 1KW to 150 KW. Our 150 KW off - grid solar power system is one of the biggest off-grid power plant in Belgaum. Deepa Solar’s Off-grid Power Plants are not only green but also economical .It is the best outlay opposed to escalating  fuel and grid charges.

Block Diagram & Technical Specification Hybrid Solar PCU 3 - 100 Kw

Hybrid PCU input active power factor correction as per ieee-519 standard, solar power input & wind power Input – hybrid PCU with single phase output and three phase output & load reactive power compensation .

Main Features
  • Load sharing between solar, Battery, Grid, Wind & DG.
  • 100 % Utilization of solar power using Power sharing MPPT Converter and solar PCU.
  • Industrial Grade IGBT inverter with complete Galvanic Isolation (Three phase output –Three phase single Delta Star Transformer)
  • High Efficiency Temperature compensated flat cum boost charger for extended battery life.
  • Parallel operation for Solar, Battery and Grid.
  • Load side Reactive power compensation Ensures Additional output load can be used.
  • Solar PCU module utilizes the entire power available from solar and in the event of short-fall in power availability from solar the mains power is drawn to compensate the deficit of power.
  • Power sharing in PCU for catering to the load can be configured as per our requirement. Example Solar primary source and secondary for grid third for Battery.



      Net metering is a special metering and billing agreement between utilities and their customers, whichfacilitates the connection of small, renewable energy-generating systems to the power grid. Net meteringallows residential and commercial customers who generate their own electricity from  solar power to feed the excess energy back into the grid .

 For example, if  a  residential customer has a PV system on the home's  rooftop, it may  generate  more electricity than the home uses during daylight hours. If the home is net-metered, the electricity meter will run backwards  to provide  a credit  against what electricity  is  consumed at  night or other  periods where the home's electricity  use  exceeds the  system's output. Customers  are  only billed  for their "net" energy use. On average, only 20-40% of  a  solar energy system’s  output ever  goes  into  the  grid . Exported solar electricity serves nearby customers’ loads.

Many  states  have  passed net metering laws. Differences between states' legislation  and  implementation mean that the benefits of net metering can vary widely for solar customers in different areas of the country.
