In addition, we delved into mechanisms of how this policy prompts rural household energy transition, which helps to understand multiple benefits of solar PV as a form of clean energy.
A solar module comprises six components, but arguably the most important one is the photovoltaic cell, which generates electricity.The conversion of sunlight, made up of particles called photons, into electrical energy by a solar cell is called the "photovoltaic effect" - hence why we refer to solar cells as "photovoltaic", or PV for short.
Photovoltaic Cell: Photovoltaic cells consist of two or more layers of semiconductors with one layer containing positive charge and the other negative charge lined adjacent to each other.; Sunlight, consisting of small packets of energy termed as photons, strikes the cell, where it is either reflected, transmitted or absorbed.
Solar energy, as a clean and safe alternative energy source with excellent development potential (Ahmed et al., 2013), plays a vital role in energy "decarbonisation" and is expected to overcome the negative impacts of fossil fuels, which has created a vast market and development potential for photovoltaic (PV) power generation technology.

Solar energy is the light and heat that come from the sun. To understand how it''s produced, let''s start with the smallest form of solar energy: the photon. Photons are waves and particles that are created in the sun''s core (the hottest part of the sun) through a process called nuclear fusion. The sun''s core is a whopping 27 million degrees
Solar cells are generally very small, and each one may only be capable of generating a few watts of electricity. They are typically combined into modules of about 40 cells; the modules are in turn assembled into PV arrays up to several meters on a side. These flat-plate PV arrays can be mounted at a fixed angle facing south, or they can be mounted on a tracking device that
Photovoltaic cells convert sunlight into electricity. A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity.Some PV cells can convert artificial light into electricity.

Reduce energy costs with photovoltaics. The sun does not send a bill - yousave on energy costs from day one by producing your own solar power. By investing in a photovoltaic system, you gain independence from constantly rising electricity prices. The PV system therefore pays back its purchase costs in less than 10 years - often much earlier.

A domestic solar PV system consists of several solar panels mounted generally to your roof and connected to the electrical loads within your building. The solar panels generate DC (direct current – like a battery) electricity, which is then converted in an inverter to AC (alternating current – like the electricity in your domestic socket).
Also, around 75% of the annual energy from a solar PV system is produced from May to September. You need to consider how much of the generated electricity you will use in your home, based on the pattern of generation from the solar PV system, and the pattern of energy usage and occupancy for your house.
These panels generate electricity when exposed to light. Solar PV is the rooftop solar you see in homes and businesses. Solar electric panels capture the light from the sun and convert it into the electricity that is used in your home to power your TV, kettle, toaster, phone charger, radio, oven, and so on.
