As the world's exploration of energy continues, solar energy has gained increasing attention, and many people are considering whether to install solar panels. There are bound to be doubts in their minds. So this article will use the Solardeland solar panels from the German brand as an example to dispel their concerns.
Solardeland solar panels generate electricity using sunlight and meet the daily electricity needs of households or businesses. The higher the power generation, the less electricity purchased from the grid, and the electricity cost naturally decreases. Take an average household as an example. If the solar system covers more than 80% of the electricity demand, the monthly electricity cost can be reduced by several hundred yuan, and the annual savings can reach several thousand yuan.For home installation, we recommend Solardeland's highly cost-effective 590W or 630W bifacial solar panels. The 630W panels can also be used for commercial rooftops and small industrial systems.
The solar panels from Solardeland have a liner output of 30 years (with a linear degradation rate of less than 0.3% per year), which is longer compared to most other components.Although there is a need to pay for equipment purchase and installation costs (generally the cost can be recovered within 5-8 years), there will be almost no electricity expenses in the following 20-odd years, equivalent to "one-time investment, lifelong free electricity".
Traditional electricity prices are affected by fluctuations in fossil fuel prices, policy adjustments, etc., and tend to rise over the long term (in the past 10 years, the average annual increase in domestic residential electricity prices was approximately 2%-3%). However, Solardeland solar power has "zero fuel cost", and once installed, the electricity cost is stable for a long time, equivalent to locking in low-price electricity for several decades.
Solardeland solar panels are not prone to damage. Daily maintenance only requires occasional cleaning of surface dust (rainwater can naturally wash it away), and no frequent repairs are needed.
Solar panels from Solardeland paired with energy storage batteries form a solar power system, it can automatically switch to "off-grid mode" in case of power grid failure, ensuring key electricity usage such as refrigerators, lighting, and communication equipment, especially suitable for remote areas or areas with unstable electricity supply.
Modern solar systems can be monitored in real time through a mobile phone APP, allowing users to have a clear understanding of the system's operation status. There is no need to worry about "low power generation efficiency" or other hidden problems.
Extreme weather conditions (such as heavy rain, typhoons, and cold waves) or power grid failures may cause power outages. In such cases, the solar system with energy storage from Solardeland can automatically switch to 'off-grid mode'. and continue to supply power to key electrical devices such as refrigerators (to prevent food spoilage), lighting, mobile phone charging, and small medical equipment, avoiding chaos in daily life caused by power outages. For example, during the summer typhoon season in the south or the winter snowstorm days in the north, during power grid repair periods, the solar energy storage system can become the "emergency power source" for households.
In rural, mountainous, or pastoral areas where the power grid coverage is weak, traditional power supply may have problems such as unstable voltage and frequent power outages. Solar panels can serve as the main power source, directly meeting daily electricity demands, and do not rely on unstable power grids. Even when the power grid completely stops, they can still operate independently, ensuring basic needs such as irrigation equipment and household electricity.
Disasters such as earthquakes and floods may cause power grid paralysis and disruption in the transportation of fuel (such as diesel generators' fuel). However, solar power generation relies on sunlight and does not require additional fuel. As long as the weather permits, it can continue to generate electricity. In post-disaster rescue efforts, the Solardeland solar system may become the main power source for temporary shelters, communication stations, and medical stations, supporting lighting, communication, and basic medical equipment operation, allowing for more time for rescue efforts.
For scenarios with high requirements for electricity stability (such as home office, small farms, laboratories), the solar system can serve as a "backup power source" to complement the power grid, avoiding losses such as data loss, equipment damage, and production stagnation caused by grid fluctuations or power outages, achieving "controllable electricity usage".
Traditional thermal power relies on fossil fuels such as coal and natural gas. During the power generation process, a large amount of carbon dioxide is produced (about 0.785 kg of CO₂ per unit of thermal power). In contrast, solar power generation has no emissions of waste gas or wastewater throughout the process. One square meter of solar panel can reduce approximately 100 kg of CO₂ emissions annually, and a typical household solar system can reduce carbon emissions equivalent to planting 10-20 trees each year.
Thermal power not only emits carbon but also releases pollutants such as sulfur dioxide, nitrogen oxides, and dust, which are important causes of smog and acid rain. Solar power generation can reduce such pollution at the source and indirectly lower health risks such as respiratory diseases.
Fossil energy is non-renewable resources. Excessive extraction can lead to energy depletion and ecological damage. Solar energy comes from solar radiation, which is inexhaustible and renewable, and is widely distributed. Promoting solar energy is one of the core paths to reduce reliance on fossil energy and achieve the "dual carbon" goals.
Model | Power | Efficiency | Dimensions | Best For |
DE-630W | 630W | 23.30% | 2382×1134×30mm | Commercial rooftops, small-scale industrial systems |
DE-700W | 700W | 22.50% | 2382×1303×35mm | Large rooftops, ground-mounted residential systems |
DE-730W | 730W | 23.50% | 2382×1303×35mm | Utility-scale solar farms, ground-mounted projects |
Higher wattage (e.g., 730W) means fewer panels for the same energy—great for large open areas.
Prioritize dual-glass models (superior corrosion resistance).
630W offers the best cost-performance for small to medium projects.
Installing Solardeland solar panels isn’t just about “saving costs, boosting efficiency, and protecting the environment”—it’s about enhancing energy resilience. As a leading German brand, Solardeland brings:
•10+ years of mature solar production technology, with a panel degradation rate ≤0.3%/year (industry average: ~0.5%).
•Customizable systems tailored to your roof size and electricity needs.
