PRESENTATION ONHYBRID SOLAR SYSTEM

BASED ON SUN SINE SMARTMICRO INVERTERS



SUN AS AN IMPORTANT SOURCEOF ENERGY

The demand for the renewable energy sources have been increasingrecently due to high prices of the fossil fuels and large scale pollutioncreated by them. One of the most acceptable forms of the renewableenergy sources is the energy from the sun, which is called as the solarenergy.



APPLICATIONS OF SOLAR ENERGY

1) Solar water heaters:These are used to heat water for various domestic purposes like bathingand also for industrial applications.

2) Solar cooker:These used to cook food. The raw food is kept in the solar cooker whichabsorbs the heat from the sun.

3) Solar street light:The street lights absorb solar energy during the day time, which is used toilluminate the streets at night using battery. These are mounted on the polesalong the sides of the road.

4) Solar lanterns:These are the portable lights that can be easily moved from one place to the

other. Their charging is done by solar light and they are mainly used at night.5) Solar photovoltaic cells:

These are used to power the appliances like calculator, and even thespacecrafts. They can also be used to generate electricity from solar energy,which can be used for various appliances at home. Photovoltaic cells arealso being experimented to run the electric motors installed in the vehicles torun the vehicles.



WHAT IS A PV SOLAR MODULE?

The solar module contains 12 / 24 / 36 / 72mono or poly crystalline silicon solar cellsconnected in series / parallel. All cells are

electrically matched to assure the maximumpower output possible. System voltages of 24volt DC and higher can be obtained byconnecting modules in series. Higher currentscan be obtained by connecting modules in

parallel.



CONSTRUCTION OF SOLAR MODULE

A high impact resistant and highly transparent tempered glass plate, infront side of the module, offers adequate protection against environmentalhazards such as rain, hail, snow, ice and storms. The back of the solar

module consists of a Tedlar-Polyster-Tedlar foil, offering reliable protectionagainst penetration of moisture and dirt. The solar cells are embedded inultraviolet stabilized ethyl-vinyl-acetate (EVA). The highly corrosionresistant anodized aluminium alloy frame provides structural support forthe solar module.



JUNCTION BOX OF SOLAR MODULE

The junction box provides a high quality, dust andwatertight housing for the rigid connection block. It isfitted with one cable gland. These cable glands canbe used for taking out electrical connection from the

solar module. The junction box is fitted to thealuminium frame for better mechanical strength.

Inside the junction box there is a 3 pole connectionblock. Two bypass diodes can be incorporated in tothe junction box offering an adequate "hot spot"

protection of the solar cells. Solar modules of 20Wand below are connected with junction box having 2poles. There is no provision for connecting by passdiodes in these modules.



ADVANTAGES OF PV SYSTEM

a) Solar panels can be installed in houses / roof-tops and cheapbarren lands not frequently affected by climatic changes and that

typically have sunny weather conditions throughout the yearb) Reduced operating costs given the fact that solar power is free.c) Harmful effects to the environment is reduced (no carbon

emissions) as compared to using other sources of energy likecrude oil & coal.

d) Reduced dependency to imported crude oil & coal.



UNIQUE SPECIFICS OF PV SYSTEM

• Requires space of 80 sq.ft per KW

• Works only with sun light during day time (Typically 8 hours)

• Average efficiency of the Output power from the inverterconnected with module is not more than 65%



DIFFERENT TYPES OF PV SOLAR SYSTEM



OFF GRID SYSTEMS



ON GRID / GRID-TIE SYSTEMS

(Centralized Inverters)



STRING INVERTER BASED ON-GRID SYSTEM



SUNSINE SMART SOLAR INVERTER SYSTEM



• Is a micro-inverter which converts direct current (DC) from a single solarpanel to alternating current (AC). The electric power from several micro-inverters is combined and sent to the consuming devices.

• Produce grid-matching power directly at the back of the panel. Arrays ofpanels are connected in parallel to each other and fed to the grid.

• Is modular, scalable and maximizes the solar power harvest.

SUNSINE SMART SOLAR INVERTER



• Complements the Sunsine Smart Solar Inverter.

•

Controls the source of the power to the user by the inbuilt smartlogic with levels of control.

• Used to share all the power sources namely Utility, Solar, DG andBattery.

• Depending on the availability and usage, the system switchesbetween the power sources.

Advantages of Hybrid Solar System with Smart Solar

Inverter

• Modular and Scalable

•Optimizes the energy harvest.

•

Reduced installation costs.• Improved system reliability from 5 to 20 years by reducingconverter temperatures and removing fans.

• Converters that are tied to the grid eliminate the need forbatteries in many applications.



COMMERCIAL ADVANTAGES

• Reduced power & oil bill up to 60%

• 30% subsidy from Government

• 80% accelerated depreciation under Renewableenergy Section of IT act of GOI
