What is a Solar Panel on Roof?

A solar panel on roof is a system placed on the top of a house or building to capture sunlight and change it into electricity. This power runs lights, TVs, fridges, and other home machines. People like this option because it is clean, renewable, and saves money.

Types of Solar Panel on Roof

There are three main types used today:

1. Monocrystalline Panels

• Made from single crystal silicon.

• Black color and very efficient.

• Best for homes with small roofs.

2. Polycrystalline Panels

• Made from many crystal pieces.

• Blue color and less costly.

• Works well in sunny areas.

3. Thin Film Panels

• Light and flexible.

• Lower efficiency but cheap.

• Good for large roof spaces.

Popular Brands of Solar Panel on Roof

Some top brands include:

• Jinko Solar – Known for high quality, price about Sh. 8,500 to 12,000 per panel.

• Trina Solar – Offers good efficiency at fair cost, price about Sh. 8,000 to 12,000.

• Canadian Solar – Balanced performance and strength, price about Sh. 8,500 to 12,000.

• Longi Solar – Excellent performance, price about Sh. 8,500 to Sh. 12,000.

Price of Solar Panel on Roof

The price depends on type, brand, and size. On average:

• 300W panel: Sh. 8,000 to Sh. 10,000.

• 400W panel: Sh. 9,000 to Sh. 13,000.

• 500W panel: Sh. 11,000 to Sh. 14,000.
  Extra cost comes from wires, batteries, and inverters for a full system.

Performance Curves and Datasheet Example

A panel datasheet often shows:

• Maximum Power (Pmax): e.g., 400W.

• Voltage at Pmax (Vmp): e.g., 40V.

• Current at Pmax (Imp): e.g., 10A.

• Efficiency: e.g., 21%.

• Temperature Coefficient: e.g., -0.35%/°C.

Performance curves display how a solar panel gives power under different sunlight and temperature conditions. A 400W panel may give full power at noon but lower power in the morning or cloudy times.

Benefits of Solar Panel on Roof

• Saves money on electricity.

• Increases house value.

• Good for the environment.

• Lasts 25 years or more.

• Low maintenance.
