Solar optimizer vs. inverter with shadow management
Shading of solar systems is a major problem. It is not only the loss of yield that threatens if the PV system is regularly exposed to shadows. The solar system is only as good as the weakest module. Although the collectors lying in the sun continue to produce energy at full capacity, the electricity accumulates in the shaded part. Too much energy on one spot means heating of the affected area. In the long term, there is a risk of damage or total failure of the solar system. A sophisticated one PV shadow management or inverter is essential for every PV power production owner.
Used to be a good one shadow management Only possible through expert and well thought-out planning, new PV builders now have better alternatives to get more out of their system.
Earlier opportunities in shading
- In the case of fixed shadows, the affected areas were usually simply left unpopulated. In this way, collector area was given away, but the system could be spared and, as absurd as it may sound, the electricity production could be kept constantly high.
- Areas that were exposed to shifting shadows during the day could be localized before(!) the system was actually on the roof, in order to then connect the affected modules with string connection to the inverter separately and thus protect them from those not affected to separate. Subsequent rewiring was very time-consuming. Planning errors meant severe losses in production and a shortened service life of the plant.
- Areas that are changing Shading were exposed to, could only be used insufficiently until recently. Opportunities for optimization had to be created.
Inverter with shadow management - a short explanation
inverter with PV shadow management can detect drops in performance fully automatically and regulate the circuit in such a way that overheating should no longer occur. They also keep production at a constant level. With their high price and the problems involved in retrofitting existing PV systems, they are a possibility for PV shadow management for people who are planning to build a new PV system, but not a real alternative for owners of already built and existing solar systems.
Performance optimizer PV system such as the Tigo Optimizer or the Huawei Optimizer briefly explained
Unlike inverters with shadow management Performance optimizer PV system again Tigo Optimizer Tigo ts4-ao or the Huawei power optimizer Sun2000-450w-p2 connected directly to the respective solar collectors. They are built so small that they can be flexibly connected to any solar collector model. In addition, they are very cheap and therefore promise a quick amortization. Even existing solar systems can be retrofitted with them afterwards. They promise an increase in performance of up to 25%.
Inverter vs. power optimizer - pros and cons
Whether a Performance optimizer PV system or a Inverter with shadow management is the right solution for your PV system needs careful consideration. After all, it's about producing the precious electricity for your own home in order to be able to escape the high prices of the energy crisis and protect the environment. In any case, you should think carefully in advance about how you can get the best out of your solar system. So that you can get a better idea of the pros and cons of one inverter with shadow management and from solar optimizers can do, you will find below a list of pros and cons with the most important points.
Inverter with shadow management
-- Effective increase in performance
-- Meanwhile some models available with Shadow management inverter feature
-- If wired well, relatively low maintenance
-- Not flexible
-- Not an option for existing systems
-- No emergency failure function, if there is overheating, there is a risk of major damage
Complicated circuit, only good PV builders can connect effectively
Power optimizer PV
-- Low price
-- Fast payback
-- Flexible connection options for flexible Shadow management inverter
-- Retrofit option for existing systems
emergency failure function
-- Protection against overheating and damage to the system
-- Monitoring using the innovative Huawei Optimizer App anytime possible
-- Use increases the service life of the entire solar system
-- Performance increase of up to 25% possible
-- Relatively new to the market Tigo Optimizer experiences so far ----mixed, Huawei Optimizer Experiences pretty good so far
-- Solar system builders are not very familiar with this innovative product
As you can see, both options have their pros and cons. You should weigh up what makes more sense for your own system. Are you in the process of planning a new building?
Then a Shadow management inverter maybe the better choice. However, do you already have a solar system on your roof at home and were you perhaps unaware of the problems of shading with a solar system during planning and construction?
Performance optimizer PV system are a great option for retrofitting existing systems and thus optimizing their performance. Either way, a PV system is a great opportunity to do something for the environment independently and to protect yourself from the effects of the energy crisis, especially in this day and age. Exploding electricity prices leave you cold when you get the best performance from your PV system.
