What is a Solar Energy System (SES)? Working Principles and Types

What is a Solar Energy System? A solar energy system is a system composed of photovoltaic (PV) panels that directly convert sunlight into electrical energy, along with components that prepare this energy for use. The basic working principle is based on photons hitting semiconductor materials, creating electron movement, and thereby generating DC (direct current) electricity. SES Types SES Type | Description | Application Area | Power Range --- | --- | --- | --- On-Grid | Generated energy is sold directly to the grid | Homes, workplaces, factories | 3kW - 10MW+ Off-Grid | Stored in batteries, no grid connection | Caravans, summer houses | 1kW - 50kW Hybrid | Both grid and battery support | Homes, commercial facilities | 5kW - 100kW Micro SES | Balcony or small rooftop installation | Apartment units | 0.3kW - 1kW Caravan/Boat | For mobile living spaces | Caravans, boats | 100W - 2kW Advantages - Up to 80-100% savings on electricity bills - Long lifespan of 25-30 years - Environmentally friendly, zero carbon emissions - Energy independence - Increases property value - Government incentives and VAT exemption Disadvantages - High initial investment cost - Variable production depending on weather conditions - No production during nighttime - Maintenance requirements 💡 Expert Advice: Before making a solar energy investment, be sure to have a professional site survey and feasibility study conducted. At Ali Vural Enerji, we offer free site survey services.
