Isolated from Grid Problems◦ Uninterrupted Supply (with storage).◦ Owner of solar system.
Opex ◦ The Operational expenses of a solar system is lower than a generator set due to its high maintenance cost.
Capex◦ The Capital expenses of a solar system is higher, in the short-term, than a generator set. However, due to
the high Opex of a generator, it is consider negligible.
Increased Fuel Prices◦ The price of fuel is always on the rise.
Economical◦ Reduces electricity bills when partially/fully connected to grid.
Solar Technologies progressively developing. ◦ These new advances help our system to become more efficient and cheaper.
Green◦ Environmental friendly, reduction in noise, pollution, CO2 emission, less carbon footprint.

Capex◦ The Capital expenses of a solar system is higher, in the short-term, than a
generator set. However, due to the high Opex of a generator, it is consider negligible.
Locality Constraint due to availability of Sun◦ Dependent on sunny days, otherwise will have to rely on storage.
Applicable for Small Scale◦ Too costly for large scale due to large amount of batteries, therefore more
expensive.
Reliability of Electronic Devices◦ Must be developed by a trusted brand to avoid faulty systems.
