state forms of energy which is derived from the sun
Two forms of energy that are derived from the sun are: Solar radiation: Solar radiation is the energy that is emitted by the sun in the form of light and heat. This energy is absorbed by the Earth's atmosphere, oceans, and land surfaces, and it is the primary source of energy for all life on Earth.Read more
Two forms of energy that are derived from the sun are:
- Solar radiation: Solar radiation is the energy that is emitted by the sun in the form of light and heat. This energy is absorbed by the Earth’s atmosphere, oceans, and land surfaces, and it is the primary source of energy for all life on Earth.
- Photovoltaic energy: Photovoltaic (PV) energy is the energy that is generated by converting sunlight into electricity using solar cells. PV cells are made up of semiconductor materials, such as silicon, which absorb sunlight and release electrons, which are then collected and used to generate electricity.
See lessdetermine the battery capacity of a system having a daily energy requirement of 360 watts hours
The amount of time that the system will be operating each day: This will determine how much energy the system will need to be able to store in order to meet its daily energy requirement. The efficiency of the battery: This will determine how much of the stored energy will be available for use by theRead more
Based on this information, the battery capacity of the system could be calculated using the following formula:
Battery capacity = Daily energy requirement / (Operating time x Battery efficiency x DOD)
For example, if the system will be operating for 8 hours per day, the battery has an efficiency of 80%, and the DOD of the battery is 50%, the battery capacity would be calculated as follows:
Battery capacity = 360 watt-hours / (8 hours x 0.8 x 0.5)
Battery capacity = 360 watt-hours / (3.2 watt-hours)
Battery capacity = 112.5 watt-hours
Therefore, the battery capacity of the system would be approximately 112.5 watt-hours.

- Determine the total daily energy consumption of the system, taking into account all of the electrical devices and appliances that will be powered by the solar system.
- Calculate the total daily energy demand of the system, taking into account factors such as the efficiency of the solar panels, the orientation and tilt angle of the panels, and the amount of sunlight that the panels will receive.
- Calculate the total daily energy production of the solar system, taking into account factors such as the size and capacity of the solar panels, the efficiency of the inverter, and any losses that may occur in the system.
- Compare the total daily energy demand of the system with the total daily energy production of the solar system to determine whether the system will be able to meet the energy needs of the system.
- If the total daily energy demand exceeds the total daily energy production of the solar system, consider ways to reduce the energy demand or increase the energy production of the system, such as by adding additional solar panels or improving the efficiency of the system.

In the context of planning a solar system, peak power refers to the maximum amount of power that the solar system is expected to produce at any given time. This is typically measured in watts, and it is an important factor to consider when determining the size and capacity of the solar system, as well as the number and type of solar panels and other components that will be needed. Peak power is typically calculated by taking into account factors such as the amount of sunlight that the solar panels will receive, the orientation and tilt angle of the panels, and the expected efficiency of the solar cells.

A voltmeter is used to measure the voltage of an electrical circuit. In the maintenance of a solar electric system, a voltmeter may be used to test the voltage of the system to ensure that it is operating within the correct range.
Distilled water may be used to clean and maintain the system, as it is less likely to leave deposits or cause damage to the system.
Baking soda may be used to clean the system, as it is a gentle, non-toxic cleaner that is effective at removing dirt and grime.
A hydrometer may be used to test the electrolyte solution in the system’s batteries to ensure that it is at the correct level. This is important because the electrolyte solution helps to regulate the charge and discharge of the batteries, and it needs to be at the correct level in order for the batteries to function properly.

- 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 itself. This heat can then be used for a variety of purposes, such as heating water for domestic use or for generating steam to power a turbine.
- Concentrated solar power (CSP) systems: CSP systems use mirrors or lenses to concentrate sunlight onto a small area, where it is then used to generate heat. This heat can be used to produce electricity, or it can be stored for later use.
- Solar sails: Solar sails are large, lightweight structures that are propelled through space by the pressure of sunlight. They do not generate electricity, but they can be used to power spacecraft by harnessing the momentum of sunlight.

- 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 power output, as higher temperatures can reduce the efficiency of the solar cells. This is because the higher the temperature, the more difficult it is for the solar cells to convert sunlight into electricity.
- The orientation of the module: The orientation of the module can also affect its power output. In general, a module that is oriented directly toward the sun will produce more power than a module that is not oriented directly toward the sun. This is because the solar cells in the module are most efficient when they are receiving sunlight directly from the sun.

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.
