This is an excellent question. If you have a solar system, you would definitely want to know your return on the investment. In this quick article, we will share with you the tools needed to calculate the amount of power your panels output. We will also mention some of the criteria that may affect solar panel efficiency. What is the Standard Test Condition Rating? When choosing a solar panel, you would have referred to the Standard Test Condition (STC) rating to ensure the panel can generate the required amount of energy. The STC rating is indicated by a number listed on the back of the panel. ...

If you’re considering a solar installation for your home or facility, you may want to consider learning about measuring solar radiation. Why is this important? Because the design of your solar system (type and quantity of PV panels, etc.) is affected by the amount of sunlight present in the location of your installation at a given time. In this article, we take a look at solar radiation, global solar radiation and the methods to measure solar radiation.  What is solar radiation? Solar radiation is often defined as the energy reaching the earth from the sun. A large part of this is visible...
