How to assess a solar panel

Panel Efficiency

The efficiency of a panel is the percentage of the energy in the sunlight that hits the panel surface which is successfully converted into electrical energy. Quality panels have an efficiency of at least 18%

Solar Panel Wattage

Wattage is a measure of the amount of power generated by the panel. The suns energy generates approximately 1,000 Watts per sq/m – so the Wattage of a panel is the area of the panel x the efficiency of the panel. ie. 1000 x 1.6sqm x 20% = 320W

Performance Warranty

The power output of a PV panel decreases over time due to degradation of the cells. The performance warranty defines the minimum level of performance in 25 years. Expect 80%+ with performance solar panels exceeding 90% after 25 years

Product Warranty

Solar Panels are exposed to the elements and the manufacture quality is vitally important. The product warranty covers defective materials or manufacturing faults. Most panels offer 10 or 12 year product warranties with premium panels offering 25 years
