Choosing The Correct IoT Solar Panel For Your Application

Selecting the bet IoT Solar Panel

The sunlight is a great source of power, and it can be used to charge various kinds of batteries. Parametric offers a solution that uses solar panels to charge batteries in their People and Traffic Counters. However, while the solution works great, it is important to remember that the choice of the IoT Solar panel in the right size matters.

The main criterium that determines if the solar solution will even be possible is the place of use. Additionally, things like fog, dust and even cloudy weather may affect the performance of the IoT solar panel system.

Parametric has in their portfolio a wide range of products suitable for various use cases. They have a range of solar panels with integrated charges and batteries for solar panels from 5V up to 20V.

As mentioned before, it is critical to properly select the correct solar solution. This article may help with that choice a little.

PVGIS – Photovoltaic Geographical Information System

The PVGIS is a great tool that can be used for the simulation of the solar power system. It uses meteorological data at the desired location. This is a free online tool and can be accessed at the link below.

Simulation

The first step for the simulation is to type the address or select the desired place by clicking on the map. Once the place is selected, you need to enter the technical data of the solar panel.

Choosing the location of the solar panel.

Go to the Off-Grid tab and type the correct details of the solar system. For example, parametric offers the 17W solar panel with a 40° mounting bracket. In this case, settings should look like this:

Parameters and Values explanation.

Once all values are entered, it is time to run the simulation. Click on the Visualise results button.

The 1st visualisation

The most important output from the simulation is the Percentage days with empty battery.

In this example, at the chosen location, the value is 1.8%.

If the value is 0, there is a very good chance the solar powered system will work in the desired place. If it is not, like in this case, a more powerful system should be chosen.

To simulate if the solution would work with the bigger IoT solar panel in this location, we need to go back to the table with details of the solar system and change the Peak power to a higher value. Let’s try a 60W panel instead of 17W.

Adjusting the solar panel power.

And simulate the results again…

The 2nd visualisation

Now, the value of percentage days with an empty battery is 0, which means the 60W solar system should work fine for this location.

Disclaimer

The PVGIS simulation is based on a meteorological data model (PVGIS-NSRDB solar radiation database). There can always be unpredictable weather situations where too little solar energy is stored and the system will switch off.

Smart Capacity Monitoring with Parametric

The UK Government announced some of the biggest changes to lockdown restrictions in England since March yesterday. With many premises now set to reopen on 4th July, we’ve taken a look at how the new Parametric smart capacity monitoring solution can help monitor capacity and ensure customer safety going forward.

Over the last three months, we’ve all become accustomed to the 2 metre social distancing guidelines. As we approach stage 3 of England’s lockdown exit strategy social distancing is due to be lowered to 1 metre+ in areas such as bars, hotels and restaurants where the 2m rule is more difficult to apply.

Based on the latest Government guidelines (dated 23/06/2020), Restaurants, pubs, bars and shops should all calculate the maximum number of customers they can accommodate to reasonably follow social distancing. This is where the Parametric smart capacity monitoring solution can help!

Meet the Parametric PCR2-XIO

Smart Capacity Monitoring Post Lockdown

Paired with the new specially designed light pole, the Parametric outdoor people counter sensor can be configured to your capacity numbers to display a green or red light based on whether it’s safe to enter or not. This compact device can sit neatly in your venues entrance to help manage queues.

What does it do?

The Parametric PCR2-XIO is a bidirectional counting sensor which uses radar signals to monitor the number of people entering and leaving your premises. With an XIO extension board for digital outputs, the sensor can be configured to work alongside other devices to control equipment, lamps and/or access control systems.

We’re here to help

We have a wide range of sensors available to support businesses adjusting to the ‘new normal’. Get in touch to discuss your requirements with one of our experts today.
