Solar suitable: the economies of installing home solar power

Does installing solar power at home eventually pay for itself? According to Consumer New Zealand, it all depends whether you are "solar-suitable". Factors include: how much sun your house gets, the pitch of your roof, how much and what time of day you use power, and how much you sell back to the grid. Also, factors such as how much power prices and buy-back rates fluctuate, and the lifetime cost of your system, including repairs. Electricity and gas price comparison service Powerswitch manager Paul Fuge has has done the research for Consumer NZ. He tells Lynn Freeman he also had solar installed on his own house the week before lockdown.
