	The 5 Factors Influencing Your Solar Energy Output

Despite the availability of the solar technology for a long time, it has found widespread consumer usage only recently. If you are looking to purchase solar panels, you should find out the amount of energy generated by the panels.

There are many factors that decide the quantity of electricity consumed by a solar panel unit. Few are fixed, while others change according to the place and time. But the good thing is that all these factors can be determined, thereby making purchasing and using solar technologies a secure investment.

5 Factors Affecting Your Solar Panels' Productivity:

1. Panel's highest Output – the factor separating the solar panels is their highest electrical output, calculated in Watts. This number can go from a few watts for small panels to 240Watts for big ones. Most panels today provide the highest output of 120Watts. The highest electrical output obtained under particular condition, when the sun is overhead at noon and the sky is clear, with the solar panel turned at a best angle, towards south.

2. Weather Conditions – one major factor affecting the output is weather conditions. Cloudy, hazy and fog prevent a part of the suns' energy from coming to the panel’s surface. So in theory, the out of the panel will be highest on the clear days.

3. Time of Day – the solar energy reaching the earth is highest at exactly the noon. Even in the initial hours of the day or late afternoon, the panels do generate electricity. In summer, as the days are longer and sunny hours are higher, the system will produce more output than in winter.

4. Distance from equator – the distance from equator has a major effect on the quantity of solar energy falling on your solar panel. As you near the equator, your solar panels will produce more electricity.

5. Fitted Tilt Angle - the solar panels' tilt angle will definitely affect the effectiveness of your solar panels. The best angle ranges from place to place, based on the latitude. It also depends on your particular energy needs, if you want more output in summer or winter, in noon or early morning.

The best part of solar energy technology is that as it is old, we can easily determine the effectiveness of the solar panels. Both fixed and variable factors can be computed by using past data and give an exact idea of your solar systems' later energy production. This will help you compute the time required to recover your investment.

Ensure your local solar panels dealer gives you a proper idea about your systems' efficiency. Add the cost of grid electricity, besides the incentives offered by the local authorities to come up with the period of your ROI.
