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
