Recent solar PV array installation explosive boom in Latvia was initiated by high energy price during 2022, when investors expectation was supported by government promotion politics. However after short period of solar power connection to national grid system operator face problem with accomodation of this huge energy flow during sunny days time. Hourly price for electrical energy start to reflect weather condition, during intensive solar time and excpesially in weekends cost for energy in grid become negative. Netto energy acount system introduced for small microgeneration will be availabe only up to 2029. Therefore solar electricity consumption in frame of generation network can become a solution for already created arrays. Heat pump based on vapor compression cycle request significant amount of electrical energy, due to that given paper consider results of heat pump coupling with solar PV array for real installation in Latvia
