Technical FAQs 3

What is solar cell efficiency?

Solar cell efficiency is nothing but the ratio of output energy to the input energy from the sun. The percentage of sunlight that a solar cell can convert into electricity determines the efficiency of a solar panel. The more the sunlight, the greater the efficiency of the solar panel will be.

What does'solar panel efficiency' mean?

What does ‘solar panel efficiency’ mean? 'Solar panel efficiency' refers to the amount of naturally occurring light a solar panel can convert into electricity in standard test conditions, which is a set of environmental factors used across the industry to measure efficiency.

Are solar panels more efficient?

Solar panels are getting more efficient every year, as are the appliances in your home. Just look at lightbulbs as an example: modern LED bulbs use 85 per cent less power than traditional incandescent bulbs.
