Situations favouring use of solar power installation
Remote or isolated locations: Solar power can be a particularly useful source of energy in remote or isolated locations, where it may not be feasible to connect to the grid or where the cost of transporting fuel may be prohibitively high. Off-grid applications: Solar power can be used to provide eleRead more
types of solar harvesting devices
Photovoltaic (PV) panels: PV panels are the most common type of solar harvesting device. They use semiconductor materials, such as silicon, to convert sunlight into electricity. Solar thermal collectors: Solar thermal collectors are used to capture the heat from sunlight, rather than the light itselRead more
Factors affecting the power output from a solar cell module
The amount of sunlight that the module receives: The more sunlight the module receives, the more electricity it will produce. This is because the solar cells in the module need sunlight in order to generate electricity. The temperature of the module: The temperature of the module can affect its poweRead more

A solar cell is a device that is used to convert sunlight into electricity. It is made up of semiconductor materials such as silicon, and it operates by absorbing sunlight and releasing electrons, which are then collected and used to generate electricity.
Irradiance is a measure of the intensity of solar radiation. It is typically measured in units of power per unit area, such as watts per square meter (W/m²). In a solar PV system, irradiance is an important factor in determining how much electricity the system will produce, as it directly affects the amount of sunlight that the solar cells are able to absorb.

Switches are devices that are used to turn electrical circuits on and off. In a PV solar system, switches may be used to control the flow of electricity from the solar panels to the inverter, which converts the electricity from direct current (DC) to alternating current (AC).

Switches are devices that are used to turn electrical circuits on and off. In a PV solar system, switches may be used to control the flow of electricity from the solar panels to the inverter, which converts the electricity from direct current (DC) to alternating current (AC).
Socket outlets are electrical outlets that are designed to accept plugs from electrical devices. In a PV solar system, socket outlets may be used to provide a convenient way to plug in and power devices such as laptops, phones, or other electronic devices.
Circuit breakers are safety devices that are used to protect electrical circuits from damage due to overloads or short circuits. In a PV solar system, circuit breakers may be installed to prevent damage to the system if the electrical load becomes too high or if there is a short circuit.

Explain i. photo-voltaic effect, ii. tracking as used in solar systems
The photovoltaic effect refers to the process by which solar cells convert sunlight into electricity. When sunlight hits a solar cell, it causes the electrons in the cell to become excited and move around, creating an electric current. This current can then be used to power electrical devices or canRead more
The photovoltaic effect refers to the process by which solar cells convert sunlight into electricity. When sunlight hits a solar cell, it causes the electrons in the cell to become excited and move around, creating an electric current. This current can then be used to power electrical devices or can be stored in a battery for later use.
Tracking, refers to the ability of the solar panels to move and follow the sun’s movement across the sky. This allows the panels to always be facing directly at the sun, maximizing their ability to convert sunlight into electricity. There are two main types of tracking systems: single-axis tracking, which allows the panels to move along a single plane, and dual-axis tracking, which allows the panels to move in two planes. Both types of tracking systems can significantly increase the amount of electricity produced by a solar installation.

Mono-crystalline solar cells are made from a single crystal of silicon, which is known for its high efficiency. The cells are cut from the crystal in a way that maximizes their ability to convert sunlight into electricity. Because of the high quality of the silicon used and the precise cutting process, mono-crystalline solar cells are typically more efficient than other types of solar cells.
Poly-crystalline solar cells, on the other hand, are made from multiple silicon crystals that are melted together to form a block, which is then cut into individual cells. Because the crystals are not arranged as perfectly as in mono-crystalline cells, poly-crystalline cells are not as efficient. However, they are generally less expensive to produce, which makes them a popular choice for many solar installations.
