How do photovoltaics (PV) compare to other alternative power sources?
Wind generation requires a good steady wind at regular intervals over the four seasons. If you have a site where this resource is available, power production should not be a problem. Hydroelectric generation is another option. These systems require a healthy flow of water with good vertical drop throughout the year. Two points to look at are the site specific nature of these power sources and the difference in moving parts. Solar electricity many times has the advantage with both factors, sunlight being fairly universal and PV’s having no moving parts to wear and eventually fail. A combination of systems will often work the best. Many times when the clouds reduce your solar gain, wind or hydro systems will be operating at full power.
