There are products available that range from small panels (to keep batteries from losing their charge) to entire wind/solar systems (to power a large off-grid home). Wind turbines start at small 200w cabin or boat sized units to large business or farm sized units 10, 20 even 50kw. Most homes use around 500-1000kwh per month and can easily be powered by wind, solar or wind/solar hybrid systems.
There is a product or system for every requirement. We would be pleased to discuss this with you in more detail.
