Solar park developers

Hello,

I’m thinking of buying a solar park with an electric power plant, I’m looking at the options too eparkai.lt, I try to google about the developers, but after reading the reviews, the desire to deal with them seems to pass, some do not fulfill the terms of the contract, do not pick up the phone, etc. What are your experiences? Maybe there would be some advice when choosing? I plan to buy a 4.2kW ​​power plant (that would be about 350kWh per month, which is 100kWh more than what we actually consume).
