Why Solar Panels Are So Energy-Efficient

Heating is a major part of solar energy, despite its main focus on electric power. Your solar panels can definitely benefit from efficient heating to keep them well-preserved.

The sun is a major source of solar energy, but many have wondered about the efficiency of solar panels throughout the years. With improving technology, efficiency has improved to the point where most panel systems can easily produce enough energy to heat water for the home and pools. There are efficient and inefficient ways to go about this process.

To save wear and tear on your panels, you need to consider a flow control system. Due to water's tendency to randomly circulate, older solar panels may take quite a while to heat up. This is very inefficient because the panels are forced to heat up a much larger pool of water than you actually need. This results in wear and tear, not to mention lengthy waits for hot water.

In order to reduce the area of the water being heated by the solar panels, you would need a control flow system. A lot of them are advanced enough to use temperature differentials. There are two sensors that power these systems. The first is located close to the panels being used to heat the water or liquid. The second is located on or close to the liquid return valve into the panel system. Put in practical terms, one sensor measures the temperature of liquid set to leave the panel while the other measures the temperature of liquid coming into the panel.

Flow systems work by waiting for the liquid to rise to a temperature determined by you. Once the liquid meets the temperature, the system turns on the circulation pump and moves the liquid to the desired location. Since the second sensor near the return valve measures temperature of incoming liquids, it will work by shutting off the pump if the incoming temperature reaches a certain range. This process allows for faster heating times, more efficiency and less wasted energy.

Solar panels are becoming more and more popular, not just in America, but in other countries too. There are countries like Germany that have set aside large chunks of their budget for solar power development. Solar can be a cost-effective solution for you as well. Even if you're getting brand new panels, a flow control system could help you save valuable energy.
