Overview Of Solar Power Plant

2. Solar Power…
• Solar power is the conversion of energy from sunlight
into electricity, either directly using photovoltaics(PV),
indirectly using concentrated solar power, or a combination.
• Concentrated solar power systems use lenses or mirrors &
tracking systems to focus a large area of sunlight into a small
beam. Photovoltaic cells convert light into an electric
current using the photovoltaic effect.

3. Solar Power Plant Components
• PV Module
• Combiner Box(AC & DC)
• Inverter
• Monitoring & Control Devices (Dataloggers)
• Net Metering

4. We can produce electricity from the sun in
two ways :
• Photovoltaic Electricity – This method uses photovoltaic cells that
absorb the direct sunlight just like the solar cells you see on some
calculators.
• Solar-Thermal Electricity – This also uses a solar collector: it has a
mirrored surface that reflects the sunlight onto a receiver that heats up a
liquid. This heated liquid is used to make steam that produces electricity.

5. Photovoltaic solar plants working
• As light hits the solar panels(Modules), the solar radiation is
converted into direct current(DC). The direct current flows from
the panels and is converted in to alternating current (AC) used
by local electric utilities . Finally the electricity travels through
transformers and voltage is boosted for delivery onto
transmission lines so local electric utilities can distribute electricity
to homes and businesses .

6. Solar-Thermal plants working
• Solar collectors capture and concentrate sunlight to heat a synthetic
oil, which then heats water to create steam. The steam is piped to an
onsite turbine-generator to produce electricity, which is then
transmitted over power lines. On cloudy days, the plant has a
supplementary natural gas boiler. The plant can burn natural gas to
heat the water, creating steam to generate electricity.

7. Types of Solar Plant Setup
• Roof Top Mounts
• Ground Mounts
• Pole Mounts

9. PV Module Working
• Sunlight striking the photovoltaic cell is absorbed by the cell. The
energy of the absorbed light generates particles with positive or
negative charge (holes and electrons), which move about or shift
freely in all directions within the cell.

10. Function of Combiner Box
• The DC combiner box is a device that combines the output from
multiple PV modules or multiple strings for connection to the inverter.
It is typically used in the larger commercial PV power plants.
• AC Combiner is used to combine AC Output From Multiple Inverters.

11. Function of Inverter
• A solar inverter or PV inverter, converts the direct current(DC) output
of a (PV) solar panel into alternating current(AC) that can be fed into
a commercial electrical grid or used by a residential electrical
network.

12. Monitoring & Control Unit
• These basically consists of dataloggers:
A data logger (also data logger or data recorder) is an electronic
device that records data over time or in relation to location either with
a built in instrument or sensor or via external instruments and sensors.
Eg. LGate101 , LGate360, Aquasuite.
They are used for monitoring residential Solar PV systems.
Designed to collect ,store & upload energy data allowing both system
installers & owners to efficiently manage solar assets.

13. Net Metering
When solar panels generate more electricity than the homeowner can
use in an area that has net metering, the excess electricity flows back
to the grid to serve nearby neighbours while your meter essentially
runs backwards.

14. Pros and Cons of Solar Energy
Pros
• Renewable Energy Source
• Reduces Electricity Bills
• Low Maintenance Costs
Cons
• High Initial Purchase cost
• Weather Dependent
• Uses a Lot of Space

15. Solar Power Generation Process
• So basically the process of solar energy generation starts with sun
rays falling on the PV Modules due to which electron gets charged
and starts moving freely which generates DC current .
• This generated dc current is fed to dc combiner box for combining
multiple strings output of pv modules and then dc current from
combiner box is sent to Inverter for converting it into AC from DC.
• Multiple Inverters Output is sent to AC combiner box & then from AC
combiner box to residential supply or to grid via net metering.
