4 Efficiency needs to be improved
In order for PV systems to reflect cost-effectiveness, we need to use an efficient method to distribute the energy
generated during use. However, they are now often used to power alternative inefficient appliances.

5 Lack of knowledge and skills
Photovoltaic technology is an emerging technology. The lack of relevant information limits the development of its
markets and technologies.

Differences between Conventional and Non-conventional Sources of Energy:
1 Conventional sources of energy are derived from fossil fuels like coal, oil, and natural gas, while non-
conventional sources of energy come from renewable sources such as solar, wind, hydro, geothermal, and
biomass.
2 Conventional sources have limited availability and are non-renewable, meaning they will eventually run out,
while non-conventional sources are abundant and renewable.

3 Conventional sources contribute significantly to carbon emissions and climate change, whereas non-
conventional sources have low or zero carbon emissions, making them environmentally friendly.
4 Conventional energy technologies are well-established and widely used, whereas non-conventional energy
technologies are still evolving and gaining popularity.
5 Conventional energy sources are generally cheaper initially, while non-conventional sources require higher
upfront costs but offer long-term savings.
6 Conventional sources rely on centralized grids to distribute energy, while non-conventional sources enable the
use of distributed energy systems, reducing dependency on centralized infrastructure.

7 Conventional sources are often associated with geopolitical conflicts due to their reliance on limited resources
from specific regions, where as non-conventional sources reduce such conflicts as they can be harnessed
locally.

8 Conventional sources have a significant environmental impact, including air and water pollution, habitat
destruction, and resource depletion, whereas non-conventional sources have minimal environmental impact.
9 Conventional energy is considered a mature industry with well-established supply chains and job markets,
whereas non-conventional energy represents a growing industry with increasing employment opportunities.
10 Conventional sources require on going extraction and transportation, whereas non-conventional sources
enable local generation and can enhance energy independence.
Solar charge controller
A solar charge controller is used to keep the battery from overcharging by regulating the voltage and current
coming from the solar panel to the battery. It is programmed at 15-A/200-W unit and uses MPPT (maximum power
point tracking) to accelerate solar charging of the battery up to 30% per day
This device manages the power flow from your solar panels to your batteries, ensuring optimal performance and
longevity.
