I do not reside in a huge house and do not need a huge solar system. I have been told that HMS Photovoltaik systems are all scaled by easily reducing their size and capable of functioning as a unit since every panel operates independently. Any small set-up here - four to six panels? Wondering still on whether the system can continue to offer a significant savings in energy bills and whether the options in the monitoring apply with such a small array. Another question to ask would be whether balcony installations are the use case of HMS technology or is it excessive?
