Description

Key Takeaways

• A solar panel series connection increases total voltage while keeping the same current.

• It is ideal for long-distance wiring and powering systems that need higher voltage.

• Popular brands include Jinko, Canadian Solar, Trina, and Longi.

• Prices in Kenya range from KSh 8,000 to KSh 18,000 depending on the wattage and brand.

• Performance curves help you know voltage, current, and efficiency under sunlight.

• Buy trusted products from Water Equation & Solar System Ltd for quality and support.

What is Solar Panel Series Connection?

A solar panel series connection is when two or more solar panels are connected one after another. The positive terminal of one panel connects to the negative terminal of the next panel. This method adds up the voltages of each panel but keeps the current the same. For example, if you connect two 12V panels in series, you will get 24V total.

This setup is very useful when you need higher voltage for inverters, battery banks, or to reduce energy loss over long cables.

Why Use Solar Panel Series Connection?

• Higher Voltage Output: Useful for 24V or 48V systems.

• Less Power Loss: Long cable runs are more efficient at high voltage.

• Easy Wiring: Panels connect in a simple chain.

However, if one panel is shaded, the output of the whole string may go down. That is why placement is very important.

Types of Solar Panels for Series Connection

Not all panels are the same. Choosing the right type helps you get the best results.

1. Monocrystalline Panels

   • High efficiency (18%–22%).

   • Long lifespan (25 years).

   • Good for limited space.

2. Polycrystalline Panels

   • Lower cost.

   • Moderate efficiency (15%–17%).

   • Work well in sunny climates like Kenya.

3. Thin-Film Panels

   • Flexible and lightweight.

   • Less efficient (10%–12%).

   • Suitable for special projects.

Brands and Prices in Kenya

Here are some popular solar brands and their average market prices in Kenya:

Example Datasheet (Performance Curve)

Let us take an example of a 300W Monocrystalline panel:

• Maximum Power (Pmax): 300W

• Voltage at Max Power (Vmp): 32V

• Current at Max Power (Imp): 9.4A

• Open Circuit Voltage (Voc): 38V

• Short Circuit Current (Isc): 9.8A

• Efficiency: 19.5%

Performance Curve:
When sunlight is high, voltage and current rise, giving maximum output. When cloudy, voltage drops slightly but current is affected more. In a solar panel series connection, the voltages of multiple panels add up, giving higher overall power supply.

Best Uses of Solar Panel Series Connection

• Large home solar systems (24V/48V).

• Solar water pumping systems.

• Solar mini-grids in rural areas.

• Off-grid schools, hospitals, and farms.
