8 KILOWATT SOLAR LIGHT SYSTEMS

Small-scale solar power generation systems in Saudi Arabia

In line with the Saudi Electricity Company’s commitment to the objectives of the Kingdom’s Vision 2030 on renewable and sustainable energy, supporting the national economy, and conserving natural resources, and in response to the bylaw that governs the integration of small-scale solar power systems into the national distribution grid, as per the Saudi Electricity Regulatory Authority’s Administrative Decree No. (2/47/41) dated December 26th, 2019, the Small Scale Solar Power Systems services have now been launched.

Solar light sensing system

The system is based on the combination of two approaches to precisely track the sunlight: first, using multiple LDRs (light-dependent resistors) as photo sensors to track the position of the sun by balancing the resistivity using a proportional integral deprival (PID) controller, and the second approach using the time-based control for cloudy days when sunlight is diffused, getting the time GPS coordinates and time to calculate the accurate position of the sun by determining the azimuth and altitude angle.

Fully automatic booster solar water pump

The solar-specific hot water booster pump adopts an advanced digital control system and can automatically adjust the operating status according to parameters such as water temperature and water flow.The built-in temperature sensor monitors the water temperature in the solar collector, when the set threshold is reached, the water pump is activated to ensure rapid circulation of hot water.Meanwhile, the flow sensor detects the water flow, when the flow rate is lower than the preset value, it will automatically stop working to avoid unnecessary waste of energy.

The cost of solar panels

While the upfront costs of solar panels have dropped by over 70% in the past decade, a comprehensive lifecycle analysis includes several key components: initial purchase and installation ($15,000-$25,000 for an average home system), ongoing maintenance (roughly $300-500 annually), inverter replacement (typically needed once during the system’s lifetime), and eventual decommissioning costs.
