![]() ![]() Predictability is difficult on a day-to-day basis, but highly predictable in the longer term. Systems can last 20-25 years, but will require parts to be replaced along the way. ![]() Warranty periods for turbine components vary by manufacturer, but five years is common. Solar panels typically last up to 30 years. Warranty periods vary by manufacturer, but are commonly 25 years for panels, five to ten years for inverters, batteries. Operational costs are generally relatively low, but moving parts do require regular maintenance and replacement. Maintenance needs vary greatly depending on turbine type. Parts should be inspected, panels cleaned, etc. Solar panels and systems have virtually no moving parts and require little maintenance. $30,000 on average for a 5 kW system, before federal tax credits, which would bring total costs total upfront costs to around $20,000. The average cost of a 5 kW system, (based on $3.70/watt) is approximately $13,000 after tax credits. They need to be located above and away from other buildings and obstacles and at height to take advantage of wind currents. Wind turbines are space-efficient, but placement can be a problem. Solar panels take up space but can be placed almost anywhere (roofs, ground, etc.) as long as they’re facing the sun. With wind, geography matters even more than solar. Wind is not everywhere, at least not enough to count on for power generation. The sun is everywhere, although some places are sunnier than others.
