SOLAR PANEL
Designed to absorbed
the sun rays
Turn energy to electrical current
(photovoltaic effect)
a set of solar
photovoltaic modules

Discovered the photovoltaic effect which explains how electricity can be generated from
sunlight

INVERTER SOLAR PANEL
SOLAR INVERTER
Convert DC to AC
Has 3 types
Stand Alone invert
er
Battery
Backup
Inverter
Gird-ties
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

COMPARISONS BETWEEN INVERTER
SOLAR PANELS & CONVENTIONAL SOLAR PANELS
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.

ADVANTAGES & DISADVANTAGES OF
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
