Abstract :
One of the solutions needed to reduce the use of fossil fuels such as coal, petroleum,
and natural gas is to use other alternatives such as the use of solar cell technology.
Solar cells utilize direct solar energy that does not require fuel as input energy which is
then converted into electrical energy. Such a system is called the Solar Power Plant
(PLTS) system. In this thesis, solar power plant engineering design will be carried out
with an on-grid system on the roof of buildings in PT. CEI during September 2022 to
January 2023 as the solar power plant. The use of the PLTS Atap system aims to save
customers' electricity bills, get electrical energy from renewable energy sources which
is an additional power from PLN at PT. CEI by calculating and designing what is
needed in the design of PLTS. In order for that goal to be achieved, it is carried out
based on calculations and simulations using the PVSyst application. The total energy used
by the company every day is 750,960 Wh. Of the total energy, 418 modules are obtained
for the needs of the number of modules that will be used later. However, the modules
that will be used are as many as 288 modules because they take up a few percent of the
roof area. In the design of PLTS Atap at PT. CEI is able to supply electrical power of
110kW and energy generated of 192,720 kWh / year, with the number of modules
installed as many as 288 modules. With a Performance Ratio (PR) of 85%, thesystem
for this design is feasible. Meanwhile, the value for PR in simulations using PVSyst was
76.6%. This difference shows that the results of simulations using PVSyst state that the
system can still be feasible because the application has more accurate calculations.
kWh of annual production produced is Rp 1,192 /kWh.
