The geographical location and solar irradiance play a crucial role in determining the performance and efficiency of an
off-grid solar system. Here's how they affect the system:
1. Geographic location:
Latitude: The latitude of a geographic location is a key factor. Areas closer to the equator generally receive more consistent and intense sunlight throughout the year. As you move further from the equator, the angle at which sunlight is received by solar panels changes more, affecting their efficiency.
Climate and Weather: Local climate and weather patterns can affect solar system performance. Cloud cover, rain, snow, and other weather conditions can reduce the amount of sunlight hitting the solar panels, causing fluctuations in energy production.
Temperature: High temperatures can reduce the efficiency of solar panels. Solar panels generally perform better in cooler climates. Excessively high temperatures may cause the efficiency of solar cells to decrease.
2. Solar radiation:
Solar radiation is the amount of solar energy received per unit area. Usually measured in watts per square meter (W/m²). Areas with higher solar radiation are able to receive more energy from the sun, resulting in more electricity generation.
Daily and Seasonal Variation: Solar radiation varies throughout the day and between seasons. At noon, the sun shines directly on the earth's surface, when the solar radiation is the highest. In regions with distinct seasons, the amount of sunlight available in winter may be significantly lower than in summer.
3. Panel direction and tilt angle:
The orientation (direction facing) and tilt angle of solar panels should be optimized for a specific geographic location to maximize energy production. Panels should ideally face either south (northern hemisphere) or north (southern hemisphere) to capture the most sunlight.
4. Occlusion:
Shading from trees, buildings or other obstructions can significantly reduce the efficiency of a solar system. A location that minimizes shading must be chosen when installing the system, especially during sunny periods.
5. Altitude:
Areas at higher altitudes may receive more direct sunlight because there is less interference from the atmosphere. However, solar panels at higher altitudes may experience greater temperature changes.
6. Dust and pollution:
Areas with high levels of dust or air pollution may require more frequent cleaning of solar panels to maintain their efficiency. Pollutants block sunlight and reduce energy production.
Solar power home storage systemSolar Power Home Storage System is designed to store surplus solar energy captured by residential solar panels. It consists of batteries and inverters that collect and store the excess energy during the day, enabling homeowners to utilize it during nighttime or cloudy days.
