Answer :
Final answer:
To generate 20KW of power, one may require about 200-400 solar panels, depending on the power output of each panel. The panels should be placed at a location with maximum sunlight, such as the roof. The design includes solar panels, a charge controller, batteries, an inverter, and grid integration.
Explanation:
To generate 20KW of power using solar panels, you would need to establish how much power each panel can produce. Typical solar panels can generate between 50 to 140W, hence you might require about 200 to 400 panels. The actual number depends on the efficiency and the rated power output of the chosen panels.
The layout of the panels should be designed in a manner that ensures maximum exposure to sunlight, often arranged in a series or parallel depending on your energy requirements and space available. A suitable place for the installation of the solar panels in a college setting could be on the roof, as it typically receives ample sunlight and can accommodate a large number of panels.
Your overall design should have the solar panels connected to a charge controller, which will regulate the power going into the energy storage device or batteries. The batteries are linked to an inverter that converts the stored DC power into AC power for use. Any extra power generated can be supplied to the grid. The performance and economics of the design should be evaluated based on the efficiency of the solar cells, cost of installation, and energy savings accrued over time.
