Hybrid Wind And Solar Energy Systems
Written by Michael Boxwell I am often asked which is better - wind turbines, or solar modules. The answer, of course, is that it isn't as simple as stating which technology is better - both have their benefits and drawbacks and which technology is best depends very much on the application and the location of the system. For large scale applications - such as for commercial scale power production for the national grid - wind turbines are the most obvious solution.
Large scale wind turbines are efficient and effective, and can be installed in a variety of locations - including far out to sea - comparatively quickly. Unlike the early large turbines, modern turbines are virtually silent and the largest systems can generate in the region of 2 megawatts of power - enough to power over 2,000 homes. On smaller scale systems, turbines can be a good alternative to solar power, but more often than not achieve their best when implemented together with a solar system: a small wind turbine can generate electricity in a breeze even when the sun is not shining, whilst the solar modules can generate electricity during the daytime when the wind is not blowing. Small wind turbines do have disadvantages however, and are very site specific. Compared to large turbines used by the power companies, small wind turbines are not particularly efficient and need to be situated in an area of above average wind in order to generate reasonable amounts of power. They also require a very smooth airflow: the smaller turbines are very susceptible to turbulence - so if you live near to a busy road, or near trees, or in a built up area, a wind turbine is unlikely to work well for you.
