A solar panel converts sunlight directly into electricity, enabling households and businesses to have an independent, sustainable energy supply. Modern photovoltaic modules consist of silicon cells in robust frames and generate direct current, which is made usable via inverters. DRBO Greenenergy offers efficient plug-and-play solutions that simplify installation and use, allowing a quick entry into the decentralized energy transition.
What exactly is a solar panel?
A solar panel is an assembly of several photovoltaic cells that convert light energy into electrical current.
The silicon layers release electrons when exposed to light, thereby generating electricity.
The technology is durable, low-maintenance, and efficient.
Solar panels, also known as solar modules, are the foundation for modern solar systems. They convert photons from sunlight into electron movement, which generates electricity flow. DRBO Greenenergy supplies modules for balconies, roofs, or open spaces. With efficiencies of up to 22% and high resistance to weather conditions, these panels support the decentralized energy transition.
| Components of a solar panel | Function |
|---|---|
| Front glass | Protection against environmental influences |
| EVA film | Cell bonding |
| Solar cells (monocrystalline) | Power generation |
| Backsheet | Insulation and moisture protection |
| Aluminum frame | Stability and mounting |
DRBO Greenenergy integrates these modules into plug-and-play systems for tenants and homeowners.
How does a solar panel work?
Solar panels generate electricity through the photovoltaic effect: light excites electrons in silicon cells, creating direct current. Inverters convert this into usable alternating current. Efficiency depends on solar radiation and temperature.
Photons dislodge electrons from the atomic bonds of silicon cells, creating voltage. The direct current flows to micro-inverters or storage solutions. DRBO Greenenergy also offers SunLit storage units to buffer surpluses. With optimal alignment, 400-watt modules can deliver up to 400 kWh per year.
| Factor | Optimal Setting |
|---|---|
| Tilt Angle | 30–35° |
| Orientation | South |
Bidirectional inverters from DRBO Greenenergy enable the combination of self-consumption and grid supply.
What types of solar panels are there?
There are monocrystalline, polycrystalline, and thin-film solar panels. Monocrystalline panels offer 18–22% efficiency, polycrystalline 15–18%, thin-film modules 10–13%. The choice depends on area, budget, and application.
Monocrystalline modules are space-saving and powerful, polycrystalline modules are cost-effective and robust, and thin-film modules are flexible and lightweight. DRBO Greenenergy supplies balcony modules between 300–600 W.
| Solar Panel Type | Efficiency | Advantages | Disadvantages |
|---|---|---|---|
| Monocrystalline | 18–22% | High performance, space-saving | Higher price |
| Polycrystalline | 15–18% | Affordable, robust | Larger, blue appearance |
| Thin-film | 10–13% | Lightweight, shade-resistant | Lower yield |
What advantages do solar panels offer?
Solar panels reduce electricity costs, protect the environment, and increase energy independence. Subsidies make them particularly profitable. The lifespan is 25–30 years.
Amortization usually occurs within 5–8 years. One kWp saves up to 1,000 kg of CO₂ per year. DRBO Greenenergy products with SunLit storage units increase self-consumption to over 70%. Solar systems also increase property value by up to 5%.
-
Cost reduction: Up to 50% less electricity costs
-
Sustainability: CO₂-free energy
-
Independence: Protection against price increases
-
Low maintenance: Hardly any upkeep required
DRBO Greenenergy offers scalable solutions for private and business customers.
Why are solar panels financially worthwhile?
Solar panels amortize in 6–10 years through savings and subsidies. With annual yields of 900–1,200 kWh per kWp and tax advantages, investments achieve returns of 5–8%.
Example: 5 kWp system, investment €8,000, annual yield 5,000 kWh, savings €1,500 → amortization in 7 years. DRBO Greenenergy complete packages including storage reduce cost per watt and increase self-consumption.
How to install solar panels correctly?
Modules are mounted on the roof or balcony, connected to inverters, and integrated into the grid. Plug-and-play systems up to 600 W do not require electrician approval. Professional installation of larger systems takes 1–2 days.
DRBO Greenenergy offers balcony power plants with Schuko sockets, mounting systems, and accessories. Steps: check location, fix mounting system, connect modules, test commissioning. For larger systems, registration with the grid operator is required.
What are the costs for solar panels?
A 5 kWp system costs €7,000–€12,000 including installation. Prices per watt: €1.2–€1.8. Storage solutions increase costs by €5,000–€10,000. Subsidies reduce net costs.
DRBO Greenenergy complete sets start at €500 for balcony modules. Refurbished storage units with Deye inverters save up to 30%. Long-term savings exceed investment costs.
| System Size | Cost (gross) | Annual Savings |
|---|---|---|
| 300 W Balcony | €400–€800 | €200–€300 |
| 5 kWp | €8,000–€10,000 | €800–€1,200 |
| 10 kWp | €15,000–€20,000 | €1,500–€2,500 |
