The amount of solar energy reaching a specific location on the surface of the earth
at a specific time is called “insolation”and its value depends on several factors.Below is the factors of insolation except.
Seasonal Variation
Pollution
Height of the Sun in the Sky
population density
Solar irradiance is composed of what to carry packets of solar energy?
Protons
Photons
Electrons
Neutrons
Semiconductor is one of material to made Solar Pv, The commonly used semiconductor materials are? Except
Monocrystalline silicon
amorphous silicon
Microcrystalline silicon
Multicrystalline silicon
TFSC is also known as Thin Film Photovoltaic Cells (TFPV)or Amorphous PV Modules Integrating one or more thin layers of PV materials or thin film (TF) on a substrate, e.g. metal, glass, plastic etc. Below is the advantages of TFSC, except
Large scale production
It has high temperature tolerance
It requires a small of space, less additional support and etc.
uniform appearance - more attractive
Half-cut solar cells are essentially the same silicon solar cells – except that they’ve been cut in half with a laser cutter. This means that instead of the usual 60 cells found in a conventional solar panel, one with half-cut cells would have 120.Below is Benefits of half-cut cells, Except
Improve solar panel performance by increasing efficiency, thereby boosting energy
Output.
increasing of resistive loss, thereby improve Solar panel performance.
More Durability and increase life time of solar panel
Improved low light performance
Microinverters allow each panel to work individually, allowing for greater energy production and efficiency. Which statement is false about microinverter?
microinverters provide a significant advantage in shaded conditions over competing string and central inverter systems.
Microinverters minimise losses caused by panel mismatch, degradation, cabling, and external factors like soiling. In full sun or shade, you harvest more energy with Microinverters.
In contrast, with string and/or central inverters, shading on a single module not affects all the modules in that array.
Microinverters optimize the power production from each individual module to deliver maximum energy from the array; If you get shade on a module, it only affects that one particular module.
A Deep Cycle Battery is the Batteries for Solar PV System.Below statement is true about Deep Cycle Battery Except
Unlike a traditional car battery, deep-cycle batteries provide a long, steady stream of power.
It can provide a short burst of power, but nothing like a car battery.
They have strong plates inside of them that allow their power to be completely drained repeatedly without causing damage to the battery itself.
Deep cycle batteries were made to power most vehicles.
There is two type of losses in solar cell which fundamental loss and technical loss. Below is Fundamental loss type except.
Low energy Photons
Fill Factor loss
Optical loss
Voltage loss
We have two type of PV system which is off grid PV system and grid PV system. below Is Off-Grid power system components except.
Charge controller
Inverter Charger
Electricity Grid
Circuit breaker
Maximum Power Point Tracking or An MPPT algorithm sets a reference value for one of the variables (duty-cycle, current or voltage) in the power converter that interfaces the PV array to a load. Below is types of Maximum Power Point Tracking (MPPT) control methods Except.
Direct duty-cycle control.
Voltage-mode control
Single duty-cycle control.
Current-mode control
