Small Wind Mills in Peru |
|
Wind energy is not unknown in Peru. Several type of small wind battery chargers and wind pumps have been installed there since the 70's. |
|
| Wind Battery Chargers | |
|
Peru has a long tradition in design and manufacturing of wind generators, most of them using a 12-V car alternator to charge batteries. The most effective system is the three-bladed Waira (which means "wind" in the Inca language Quechua). 25 of them are installed in Peru. They are available in 2 sizes: 700 W (US$ 1950) and 1200 W (US$ 2250). |

| Wind Pumping | |
|
Irrigation using wind energy is attractive to the farmers along the desert coast, near the valleys, where the underground water is 5-40 m below ground and the area is without water for at least three months every year. The prices of the Peruvian, Dutch, American, and German-improved Peruvian irrigating wind pumps range from US$ 1,200 to US$ 3,500. Most of them have the capacity to irrigate 2-3 ha. |
|
| Maintenance | |
|
Many windmills installed are out of use because of insufficient maintenance due to lack of credit to wind pumps. However, recently, farmers' interest has revived due to the increased fuel prices (4 times increase 1985 - 1996). This makes wind pumping more competitive, but short- and medium -term credits for investment are needed very much. There is also a demand for wind pumps to be bigger and suitable to deeper wells or windmills which work most of the time and store water. Sources: RERIC News, 03.'95; 03.96. Articles by GRUPO, Peru.
