Solar power meters are small keypad devices used to measure radiated and transmitted power from solar panelsHow do they work?They work by helping you identify optimal positioning and alignment for Solar panels whether they are just being installed or readjusted. The instrument will help determine the solar power transmission percentage.Features and benefits:•Wide spectral range•Long term stability•Select either power or transmission•Solar energy measurement•Automatic transmission measurements•Long battery life (up to 100 hours in some models)•Overload indications•Auto power off features with data holding (power up and take off from where you left)•Easy to use LCD display screens available•Lightweight and compactWhere might I use one?•Solar power research•To Identify high performance opportunities•Physics or optical laboratories•Solar radiation measurement•Agriculture•Meteorology
