2. What is Solar Energy ?
• Solar energy works by capturing the sun’s
energy and turning it into electricity for
your home or business.
• Its uses sun’s energy either directly as thermal
energy (heat) or through the use of
photovoltaic cells in solar panels.
6. SOLAR ROOFTOP SYSTEM CONSISTS…
• A complete solar rooftop system
requires components to produce
electricity, convert power into
alternating current that can be
used by appliances & machinery,
store excess electricity and
maintain safety.
Components
• Solar Panels/Solar Modules
• Solar Inverter
• ACDB & DCDB
• Batteries
• AC & DC Cables
7. SOLAR PANELS / SOLAR MODULES
• Solar panels are built from a large number of
individual solar cells, also called photovoltaic cells.
Using this cells Solar Panels/Modules converts sun
rays into electricity by some Atom functionality.
• Solar panels generates electricity in DC form.
• Usually, Solar Panels have lifespan of about 25
years.
8. SOLAR INVERTER
• The Solar Inverter is an essential device in any
solar power system. Its basic function of the
inverter is to change the variable Direct Current
output of the solar panels into Alternating
Current.
• The converted Alternating Current power is used
for running your house appliances like the TV,
Refrigerator, Microwave, etc. For some particular
applications, we can directly use the Direct
Current power from the solar panel.
9. A.C DISTRIBUTION BOX
• ACDB provides load protection for AC side. It
comprises of breaker, isolators, current and
voltage monitoring, etc. It can provide surge
protection besides ensuring optimum protection
to the sophisticated electronic equipment.
• One of the fundamental functions of the ACDB
Box is eliminating the load operation at the
immediate PCU O/P end along with providing
flexible operation of various loads like general
home, office lights or Street lights and optional
loads operating optionally.
10. D.C DISTRIBUTION BOX
• In case there is some fault on course of failure
in DC side, DCDB/AJB is used for the purpose of
protecting the system irrespective of it being
Solar Panels or batteries. It is an integral and
significant aspect of the SPV system for it is
desirable that there is enough protection in DC
side.
• In order to switch off the system while a fault
occurs, there exists an Isolator/Breaker for
immediately switching off the system.
Moreover, it has also got surge protection for
saving the system from surges caused owing to
fault and/or phenomena such as lightning and
others.
11. SOLAR BATTERIES
• The batteries in a photovoltaic solar energy
system is to accumulate the energy produced
by the photovoltaic panels during the hours of
Sun to be able to use it at night or on cloudy
days. The use of batteries also allows to
provide a higher current intensity than a
functioning photovoltaic panel can offer.
• For those adventurous types without access to
a public utility and in need of a reliable and
continuous electricity source for their off-the-
grid home, battery backup is essential.
12. AC & DC CABLES
• AC & DC Cables are used for transmission of AC & DC electricity through out the systems.
