Building Your 20W Solar Power System

Let's break down the components needed to create a functional solar setup. You'll be surprised how simple it can be – it's like assembling a puzzle where each piece plays a vital role.

Essential Components

• 20W Solar Panel: Monocrystalline (19% efficiency) vs Polycrystalline (16% efficiency)
• Charge Controller: PWM vs MPPT (15% more efficient)
• Battery Storage: 12V 7Ah lead-acid or lithium-ion options
• Power Inverter: Pure sine wave for sensitive electronics

Component	Cost Range	Efficiency
Solar Panel	$25-$50	15-22%
Battery	$20-$80	80-95%
Controller	$10-$30	85-97%

Real-World Performance Data
