Old school batterij technologie in offgrid energiesystemen

Posted on by developer

De uitrol van zonnepanelen draait in coronatijd volop door, zowel in de residentiële als de zakelijke markt. Het gebruik van batterijen komt sterk op, in Vlaanderen in de vorm van de thuisbatterij en in Nederland in die van grootschalige opslagsystemen. Dit is echter niet de wereld van TSS4U. Het levert offgrid solar en solar hybride-systemen, met name voor offshore en onshore olie- en gasinstallaties. Die markt kent zijn eigen wetten, zowel wat betreft conjunctuur als technologische vereisten.

TSS4U heeft zijn roots in het voormalige Shell Solar in Helmond. Chief operational officer en mede-eigenaar Jan-Willem Linsen werkte er eerst aan netgekoppelde, daarna aan autonome industriële zonne-energiesystemen. Na de overname van Siemens Solar in 2001 zette het bedrijf een punt achter de productie van zonnepanelen in Nederland.
2 jaar later werden de offgrid-activiteiten overgeheveld naar München. Linsen en enkele van zijn collega’s besloten uit te stappen en richtten TSS4U op.

Choice of charge control technique: Active or TSS Passive MPPT?

Posted on by developer

Choice of charge control technique: Active MPPT or TSS Passive MPPT?

Pulse Width Modulation (PWM) and Maximum Power Point Tracking (MPPT) are the two most common techniques used in off-grid solar charge controllers to charge batteries from a photovoltaic (PV) array. Both technologies have been widely used in the off-grid solar industry and both are great options for charging your battery. The choice of PWM or MPPT regulation is not merely based on which charging method is “better” than the other. Rather, it encompasses the determination of which type of controller will work best in a specific system design.

PWM charge control

A PWM charge controller is a switch which connects the PV module to the battery. When in PWM regulation, the current from the PV array tapers according to the battery’s status and recharging needs. When the switch is closed, the PV module and battery will be at nearly the same voltage and the PV module operational voltage is given by the following formula:

Since the PV modules operate at the same voltage window (battery voltage), rather than a higher watt peak rating, it is more important for a PV module to be able to produce more current at the battery voltage window when used with a PWM controller.

Active MPPT charge control

 

A MPPT algorithm-based charge controller sweeps the I-V curve of the PV module to pin-point the Maximum Power Point (MPP) of the PV module in all conditions. The power conversion is done with a DC-DC converter that converts the higher DC voltage from PV modules to a lower voltage required to charge the batteries:

Effect of PV module temperature on power extracted

 

An often forgotten aspect of PV modules is the change of parameters at different temperatures. Let us consider two scenarios of PV module temperature by maintaining the type of PV module and irradiance as constant.

PV module temperature at 25°C, at STC
Ppwm
For a 24V PWM based system, considering the average battery charging voltage to be 27.45V and a voltage drop of 10% (worst case), the PV module operational voltage will be 30.2V. From the above figure, it can be seen that at a PV voltage of 30.2V, the PV power output will be 325.3W.

Pmpp
The maximum power that can be extracted from the PV module with an MPPT-based controller is 359.8W. In this case MPPT extracts about 10.6% more power in comparison to a PWM controller at a PV cell temperature of 25°C.

Above case is considered at STC. STC stands for Standard Test Conditions which is at a PV module temperature of 25°C. In reality, the PV module temperature is much higher than the ambient temperature. As a rule of thumb, the difference in temperature is approximately 20°C. Hence, it would be more realistic to consider a cell temperature of around 50°C.
PV module temperature of 50°C

From the above figure, it can be noticed that at a PV voltage of 30.2V, the PV power output has reduced slightly to 322.4W in a PWM based system, only 0.9% reduction compared to STC. The maximum power that can be extracted by a MPPT based system is 328.8W, a reduction of 8.8% compared to STC. Reducing the difference in power output to only 1.9%.

 

Hence, at the actual temperatures a PV module will operate, the advantages of the MPPT over a PWM becomes negligible as the power output from a PWM based system is very close to that for an MPPT based system.

 

TSS passive MPPT charge control

In essence, with a PWM system the MPP is not actively tracked, but MPP operation is obtained by matching the module voltage to the system voltage. This can be achieved by using TSS PWM optimized PV modules. The combination of a TSS PWM charge controller and TSS PWM optimized PV modules provides a passive MPP operation which we call the TSS passive MPPT charge control and is provided in our solid solar only solutions.

Differentiators

Space Constraint

As seen in the earlier section, at lower temperatures, the MPPT controller can extract the same power as PWM from a lower number of PV modules. This leads to slightly lower number of PV modules for a MPPT system. To partly overcome this challenge, TSS uses PWM system optimized PV modules in order to extract the maximum power out of the PV system at any given ambient temperature.

 

Ease of system sizing

MPPT is the more advanced style charge controller as they will sweep the I-V curve throughout the day to maximize the energy harvest from PV array. Consequently, sizing MPPT based charge controllers is more complex as there are many considerations to take into account in comparison to a straightforward PWM based system sizing.

 

Controller de-rating with temperature

An overlooked fact is often that all equipment is installed inside enclosures where operational temperature will be higher than the ambient temperature. This difference can be up to 20°C to 30°C and additionally controller efficiency comes into play.
With a typical efficiency of a MPPT controller being 97%, its’ dissipated power will have a large effect on the enclosure temperature. Additionally, the complex electronics will demand a power derating at higher temperatures. Risking not being able to extract enough energy to supply the load and also charge the battery.

The TSS PWM Controller on the other hand has an outstanding efficiency of 99.97%. This keeps the enclosure temperature at a lower level compared to MPPT. Besides this a PWM controller does not demand for derating at higher temperatures.

 

Reliability

A MPPT based system consists of more complex electronic DC-DC converter circuits to cater the MPP tracking. A PWM controller is of a way less complicated nature. It only has to switch the PV modules on and off, making it a more reliable solution.

 

System cost

From a costing point of view, Solar Energy Systems are implemented in two main climates:

  • High temperature: similar system cost for both MPPT and PWM
  • Lower insolation: larger number of PV modules require larger number of MPPT Controllers, this reduces the benefit of MPPT since the cost of MPPT controllers is vastly higher compared to PWM controllers

Conclusion:

It can be concluded that the choice for a TSS Passive MPPT based system or an Active MPPT based system lies in the smart interplay between the various factors that need to be incorporated while designing a specific system. At TSS, we believe the choice for a TSS passive MPPT solution is still the best solution for remote industrial environments, since it provides the highest reliability and energy security. All at the same or lesser cost.

TSS Successful track record in Africa

TSS the world’s most trusted builder of fully integrated and optimized pure solar and solar hybrid energy solutions for remote telecom sites successfully established presence in Africa with a new office in Nairobi, Kenya.

 

TSS was founded in 2003 by former management of Shell Solar. The company is headquartered in Eindhoven, The Netherlands, and has additional offices in Abu Dhabi UAE for the Middle East Market and Kuala Lumpur, Malaysia for the Asia Pacific market. We equally work with numerous partners in Europe, Asia and Africa.

With over 25 years of in-depth experience in off-grid systems, and having successfully serviced the high standard oil and gas industry and deployed over 1,500 solar and hybrid systems across Africa, South East Asia, Middle East and Europe, it was time for TSS to have a footprint in Africa.

As a result, TSS expanded its sales organization and Kenya is one of the highly suitable locations to cater for our African target market where we are experiencing a rapidly growing interest in our solutions.

 

Kenya’s location allows easy access to the rest of Sub-Saharan Africa and facilitates TSS to respond faster to customer support requests, and more efficiently support our partners.

There are thousands of telecom sites without reliable grid connection which translates into huge energy costs for operators.

 

TowerXchange, the independent community for operators, towercos, investors and suppliers has also forecasted that the volume of new build sites will be the highest in Africa with Countries, MNOs and Towercos making significant investment in cell site energy, and rural electrification with sustainable, environmentally friendly solar solutions.

TSS solutions has developed and perfected to solve exactly the kind of infrastructure challenges that operators are facing in emerging markets like Africa and addressing key concerns like grid availability, reliability, future energy requirements and expansion and how to cost efficiently power both existing and new sites in rural areas.

 

Esther and the team in Kenya will be collaborating with local partners in the Sub-Saharan region who have teams in place for installation, operations and maintenance.

Revitalize your Solar Energy System

Revitalize your Solar Energy System

In the past 30 years many large Oil & Gas companies started an off-grid solar department providing their own off-grid Solar System Solutions including their in-house developed charge control equipment. Many solar systems are now in use as the main energy supplier for vital equipment like Telecom, RTU, Wellhead control, valves, etc. Failure of the energy supply will result in high operational cost.

 

At TSS, we have seen many companies like Shell Solar, BP Solar, Total Energy/Tenesol stopping their off-grid solar activities resulting in clients not being able to maintain their current install base and to get spare parts or technical support for their Solar Power Systems. This has resulted in high downtime and high operation cost for these clients. TSS has been requested by many clients to help them in providing System Health Checks and spare parts for those systems for more than 10 years.

 

During the System Health Check our engineers provide you a report on the status of your system and which (preventive) maintenance should be carried out in order to revitalize these systems.

In order to be able to help these clients TSS has developed tailor made solutions by providing compatible new charge controllers which could replace the existing control equipment without the need of revising the whole system and including the system specific metering and alarms. Due to this we could provide a solution to our clients to keep their solar system running for the next 10 years or more without the need for a high investment for purchasing a complete new solar power system.

 

We would be happy to provide a similar tailor made solution for your off-grid solar systems that are currently failing due to the lack of spare parts or technical support from the manufacturer.
