Smart system design and support for a more independent, resilient home.
Drawing on decades of renewable‑energy research and hands‑on experience in New Zealand conditions, we specialise in designing practical, reliable solar‑plus‑wind hybrid solutions. These systems are designed to provide reliable, clean energy year‑round — especially in locations where grid access is limited or too costly to establish.
Whether you want to reduce power bills, increase energy independence, or move toward a fully off‑grid lifestyle, we can assess your household needs and recommend the right hybrid system. From technical advice to procurement and installation support, Greenwood Energy is here to guide you toward a smarter, more resilient energy future.

Overview
Hybrid micro wind and solar systems have become one of the most reliable ways to power off‑grid homes and medium‑scale farms worldwide. There is no doubt we can implement this very successfully in New Zealand as we are blessed with abundant level of sunlight and wind power. By combining two complementary energy sources, these systems provide steady generation throughout the year, even in regions with variable weather. A typical setup includes a high‑efficiency monocrystalline solar array paired with a 1–3 kW micro wind turbine, allowing households to capture strong daytime sunlight while also generating power at night or during cloudy, windy periods. Modern turbines use permanent‑magnet generators that perform well in low wind speeds, making them suitable for rural and coastal environments.
Technology
Energy from both sources is managed through dedicated MPPT controllers and stored in a lithium‑ion battery bank sized for one to two days of autonomy. A hybrid inverter then delivers clean 230V AC power for everyday household and farm loads, including pumps, tools, refrigeration, and lighting. An example is when properly sized, a system can reliably produce 20–30 kWh per day for an average house, offering a practical pathway to full energy independence. For landowners seeking more power can easily increase the unit capacities of the wind turbines and number of solar panels. With weather resilience, lower running costs, and freedom from grid constraints, micro wind–solar hybrids provide a balanced, future‑proof solution tailored to New Zealand conditions.
