Solar service rental?

Hi guys.  

What do you think about renting a solar service.  Gosolr offers packages ( Medium to Xlarge) according to your household needs. They install the equiment ( panels, battey and inverter) and you rent it as long as you wish. There is a fee for terminating the contract that is based on how long you have rented the equipment.  They do yearly inspections to check if everthings ok and if something goes faulty they replace it. According to them they also upgrade the equipment every few years. 

Rental for a medium system ( up to 900KWh per month - 8 x 455W panels, 1x 5.5 KWh lithium battery and 5 KW hybrid inverter) is R1580 per month. They did not do a formal quote, so I do not know if there is a yearly escalation.  I first wanted to know your opinion and if anyone else is maybe using their services, their opinion.

Thanks
