Martin Diprose -

With a degree in Electrical Engineering, Martin has been involved in the solar industry for many years. He is registered as an Electrical Engineer and an Electrical Inspector. Based in Palmerston North, Martin has been working as a solar design engineer at McNae Electrical Solutions for seven years. Initially he spent time on roofs installing solar, but now spends most of his time in the office. He takes a keen interest in the regulations and standards that govern the electrical and photovoltaic industry. Before joining McNae Electrical Solutions, Martin spent 10 years in Uganda living in a remote village that did not have grid electricity. Martin and his family were involved in language development work and they lived off grid on a 240-watt solar system. Today the average sized residential solar system is nearly twenty times that size. The four 60W solar panels that Martin’s family lived on fifteen years ago cost over $8 per watt. Today, solar panels cost just 80 cents per watt. Martin says, “with this pace of technology change, it won’t be long before every house in New Zealand will see it as a no-brainer to install as many solar panels as they can fit on their roof.”
