FAQ solar

Yes. You need a Hybrid or ON grid inverter (Hard hybrid inverter). Hybrid inverter can send electricity to the battery pack or to the grid. On grid inverter sends all electricity into the grid. BUT if you want to give electricity into the grid and then use it later you need a two way meter and the agreement with your local electricity supplier or your local electric grid.

2.4 kw solar power plant generates around 2400 kWh per year in Lithuania and Denmark. This could be enough for small houses or small families. Inverter supplies 3-5 kW power and 3 phases or one phase, so this should be enough for a regular one small family house. If you need more energy per year, you can choose a 4.8 kw solar power plant. 3 phases or one phase system should be chosen according to the house system. There are 3 phase or one phase systems in different houses, so you should choose the same system and for the solar system. Then it will be easier to connect the solar system to the house. In some cases it is possible to use a one phase solar power plant for a 3 phase house grid.

With a Pop-up solar 2.4 kW solar power plant you will produce around 2400 kWh annually in Lithuania, Denmark and similar countries.

Probably – no, except if you give electricity to the grid in summer time and you can get back in the winter time. Usually Solar plants will not produce much electricity in winter time, because of cloudy days, the sun is at a low altitude. It will not be enough energy for heating. But, if you are able to give electricity to the grid and then get it back, then you should save around 2400 kWh per year with a Pop-up Solar 2.4 kW plant. If you live in a very energy efficient house (A, A+ or A++ class), and the house is small, then you could heat it with this accumulated energy in the grid. You should contact your local electricity grid administrator and find out about the possibility of joining the grid with a solar plant.

Yes, if you have an ON grid or hard hybrid system and your local grid can buy electricity from you. 

Yes, you can split electricity, but then you will have to make one local small grid. You should see local laws and then probably you will have to get only one electricity meter from the grid. But if you have your only few summer houses in the same yard and you have local own grid, so you will have only integrate Solar power plant to the own grid.

You should produce around 2400 kWh annually with Pop-up Solar 2.4 kW and around 4800 kWh annually with Pop-up Solar 4.8 kW. So you should calculate how much electricity costs in your local grid and what are other taxes. These numbers are right if you use an On grid or Hard hybrid inverter and you have some load batteries to accumulate electricity or sell electricity to the grid. Only then all electricity will be taken and used. If you have an OFF grid or Soft hybrid inverter and you have only a small battery tank, you must use electricity very smartly, otherwise some electricity will just be lost, because it will not be accumulated or used when the sun shines.
