This document discusses solar panels and inverters. It begins by listing the team members and then provides information about how solar panels work by absorbing sunlight and converting it to electrical current. The history of solar panels is briefly discussed, mentioning key inventors. The document focuses on inverters, explaining the different types and how they convert direct current from solar panels to alternating current. It provides examples and diagrams of inverters and discusses their operation and advantages over conventional solar panel systems. Finally, it outlines some advantages and disadvantages of solar panels.

inverter
Use maximum
power point
tracking (MPPT)
to get max
possible power
from PV rays
Used in isolated system where the
inverter draw its DC energy from
batteries charged by PV arrays
Designed to
shutdown
automatically upon
loss of utility supply
for safety reason. And
do not provide backup
power during utility
outrages.
Designed to draw energy from battery,
manage battery charge via onboard charger
and export excess energy to utility grid.Also
capable of supplying AC energy to selected
loads during utility outrages 10

21. Inverter
• Generates more
electricity.
• Cost efficiency.
• Shade tolerant and fault
redundancy.
Conventional
• Initial cost is cheaper.
• Dangerous high DC
voltages.
• Higher maintenance cost.
• Shading module will
reduce its output.

SOLAR PANELS

24. Advantages Disadvantages
Infinitive sources
Free-of-Charge
Does not cause pollution
Can be used in remote areas
Low power consuming devices can be
powered by solar energy effectively
The equipment are expensive
Can only be harnessed when it is
daytime and sunny
Unreliable climate means that solar
energy is also unreliable as a source of
energy
Large areas of land are required to
capture the suns energy
The batteries are large and heavy and
need storage space.They also need
replacing from time to time
