Solar Energy Solutions
Our Solar vision is to generate clean energy to help reduce dependency on Fossils thereby reduce Carbon emissions into the environment making it more greener. We believe that our future generation deserve a clean and healthy environment and WE have the responsibility to provide that to them.
In line with our mission, Solen focuses on Solar Energy solutions of Power generation, Water heating and Street lighting for Residential, Commercial or Industrial customers. We also provide Electric fencing using Solar electricity, Swimming pool water heating, Garden lighting, lighting for Signboards or Hoardings. All power, heating and lighting solutions can be very cost effective option for our customers providing savings of great amount towards energy cost.
Solar Power is generated by converting Sunlight into electricity using Photovoltaic (PV) panels. A PV panel consists of number cells that convert sunlight into electricity due to Photovoltaic effect.
Solar power solution mainly consists of PV Panels and mounting structures, Inverter, Charge controller and Batteries (where applicable), Cables and protection devices. Number of power solutions are available using Solar systems.
OFF GRID
Captive: All the solar generated electricity is used directly by the generating company.
This is typically used in industries or commercial complexes where there is high demand of Power during day time.
With Battery Storage:Solar generated electricity is stored
in battery bank and used either continuously or as backup when there is no supply
from State electricity supplier.
This type of configuration is used in residences, offices or commercial complexes
where continuous supply of electricity is desired. However use of battery bank increases
capital and operation cost due to need of regular maintenance and periodic replacement
of batteries.
ON GRID
Net Metering: In this type of solar configuration the electricity meter is replaced by a Net Meter which is tested and approved by the state electricity supplier. The Solar system is tied to the Grid so that the electricity generated by Solar is either used for active load or if extra power is generated then that is exported to Grid.
Later when Solar is not generating, supply from Grid (import) is used. The net difference of Import and Export will decide bill for electricity.
This is most desired solution as it could make your electricity consumption almost free of cost.
Hybrid (combination of OFF and ON grid)
The hybrid configuration is expensive but can be installed where continuous supply is desired as well as additional generated can be exported to state supplier to reduce the cost.
Water Heating
Solar water heaters are in use for several decades across the world.
The Heat energy from Sun is absorbed by the collectors and is transferred to water
flowing through them. This is a very cost effective water heating solution saving
thousands of units of electricity per installation every year.
There are two main types of Solar collectors:
Flat Plate Collectors (FPC):
Flat Plate collector is a Copper absorber plate which is coated with a thermal absorber to improve the absorption.
Evacuated Tube Collectors (ETC):
Each tube consists of two glass tubes separated by a vacuum in between. Heat loss due to convection cannot cross a vacuum and hence it forms an efficient isolation mechanism to keep heat inside the collector tubes.
The flow of water can be forced by using a pump or not forced in which case it works on the principle of Thermosyphon. Auxillary heaters such as electric, heat pump etc. can support the solar heating during cloudy days or if a certain fix temperature is required all through the day.
Benefits of Solar systems
Monetary benefits
- Long term gains for about 25 years through huge savings on energy
- System can be designed to make your energy consumption free for the life span
- Accelerated depreciation for Commercial and Industrial users
- 30% Subsidy from MNRE (Central Govt. Ministry of New and Renewable Energy) for residential and institutions
- No VAT on Solar system in Maharashtra
- 5% Property tax reduction in Maharashtra for residential customers
- Reduced dependency on Fossils reduces import expenditure for the country’s economy
Environmental Benefits
It is estimated that one KW renewable energy generated in a year reduces 1 ton of CO2 emission in the air. This also corresponds to plantation of 2 trees every year.
Solar energy will help reduce the dependency of energy on Fossils such as Coal. This will reduce the negative impact of mining on the environment and on the health of mining workers.
