What is Solar Electricity?
Solar Electricity Definition
Solar electricity is produced by sunlight hitting photovoltaic cells, generating power.
Photovoltaic Effect
Solar energy electrical engineering relies on the photovoltaic effect, where sunlight creates electricity in semiconductor materials.
Structure of Solar Cells
A solar cell consists of a thin n-type layer on top of a thicker p-type layer, with a depletion region at their junction. 
Charge Separation
Sunlight causes electrons to move to the n-layer and holes to the p-layer, creating a potential difference.
Applications of Solar Electricity
Solar power is ideal for remote locations and moderate power needs, though it is less practical for high-power equipment.

How Vacuum Tech Replaces SF6 in Modern Ring Main Units
Ring main units (RMUs) are used in secondary power distribution, directly connecting to end-users such as residential communities, construction sites, commercial buildings, highways, etc.In a residential substation, the RMU introduces 12 kV medium voltage, which is then stepped down to 380 V low voltage through transformers. The low-voltage switchgear distributes electrical energy to various user units. For a 1250 kVA distribution transformer in a residential community, the medium-voltage ring m

Why Monitoring Accuracy Matters in Power Quality Systems
The Critical Role of Monitoring Accuracy in Power Quality Online DevicesThe measurement accuracy of online power quality monitoring devices is the core of the power system’s “perception capability,” directly determining the safety, economy, stability, and reliability of power supply to users. Inadequate accuracy leads to misjudgment, incorrect control, and flawed decision-making—potentially causing equipment damage, economic losses, or even grid failures. Conversely, high accuracy enables precis
