The efficiency of a solar panel is the conversion of the solar panel's ability to convert solar radiation into usable electricity. It is the most commonly used criterion by consumers when evaluating the quality of solar panels. Taking two PV modules as an example, under the same sunlight for the same amount of time, the more efficient one produces more energy than the other.
In a practical comparison, consider that one of the solar panels is 35% efficient, while the other is 23% efficient. Under the same conditions, a 35% efficient solar panel can produce half as much power as a 23% efficient panel. Therefore, the efficiency of solar panels plays an important role in optimal use of energy and cost savings. Here are some factors that affect the efficiency of solar panels.
- Hire professional to install
Correctly installed solar modules can maximize the absorption of the sun's radiation. As a result, the panels generate more power. Orientation and angle are the two main factors to consider when making an installation. Typically, solar modules get the best sunlight exposure at an angle of 18-36°.
Notably, temperature levels can affect the efficiency of solar panels. A rise in temperature can cause a decrease in the efficiency of the solar panel. There should be enough space between the roof and the panels to keep the system from overheating by allowing air to flow. All of these require skills and knowledge, and experts understand all of them and how best to do it.
The components of the solar panel are fixed, so it does not require a lot of maintenance. But dirt tends to collect on the surface, reducing efficiency. However, when there is dirt on the surface, the absorption of sunlight is also reduced.
A few factors determine how often you should clean your solar panels. First, consider how often it rains in your area. Rain washes away dirt considerably, meaning you don't have to clean it. Dirt and dust don't have much effect on efficiency, but you shouldn't ignore it as it's probably around 5% over the course of a year. Depending on your region, yields may be reduced by more than 20%.
- Use during peak sun exposure
Solar panels are usually generated from the sun's rays. In other words, it can only generate energy during the day. For maximum effect, try to use it during the midday hours of the day, this way, you will increase the efficiency of your solar panel. Always make sure you adjust your solar heating and cooling equipment to your desired temperature during the day. At night, you turn them off to reduce electricity usage. If your inverters have the ability to store energy, make sure they are fully charged to reduce wasted power.
- Choose the right solar panel
The solar panel you choose determines the efficiency it offers you. Before deciding on one type of solar panel to use, look at the different solar panel models. Learn and ask more questions about its power capacity and those other features to improve energy conversion.
- Install a solar concentrator
This setup enables you to maximize the power from your solar panels. It helps to concentrate solar light and convert it into electricity. The main reason for installing this unit is to concentrate most of the radiation falling on the solar panels.
- Proper placement of solar panels
The angle and orientation of installing photovoltaic panels must be correct. Make sure your PV panels are set up in a location that allows them to receive maximum sunlight throughout the year. Pay attention to the tilt angle of the panels to ensure they are exposed to direct sunlight uninterrupted throughout the day.
