Powerspout turbines come in 3 models to suit various sites with various heads. To choose which one will work best you must first have an idea of the head of pressure available. This is the vertical height difference between the intake and the turbine. The diagram shows how much power you can get from any site, given the available head and the flow. Click on the diagram to see it larger. See below for videos of the various turbine models.
The power output you can get, whether on or off the grid will be roughly five times the head, times the flow. So for example if you have a head of 20 metres, and 10 litres per second flow of water, then you can expect about 5 x 20 x 10 = 1000 watts of power.
If you understand these matters and want to quickly assess the feasibility of a site, then you should go straight to the online calculator on the Powerspout website. This will allow you to design the whole thing including the pipe and the cable. At the end you can enter your email and have the result sent to you. If you want further help from me then you should also choose “Scoraig Wind Electric” in the drop-down menu for dealers. That way I get to see your data, and can advise on the best choices.
If you need more information then I suggest you download the manual, which I helped to prepare. There is a separate manual for the calculator if you need that. Here is a site with lots of documents organised nicely.
Everybody wants to know what it will cost of course so here is a link to the new shop web site with all of the prices and details of the options and extras. Note that shipping is free for orders over US$1,000 (£770) but only up to a 29kg limit. The shopping basket will tell you how heavy your order is. The price of the basic turbine is GB £1,230 plus VAT including shipping from New Zealand (which happens in a few short days). I can offer trade discounts for genuine trade enquiries (installers, resellers).
The turbine is only part of the whole system that can give you 24-hour power, on or off the grid. I can advise how to put a system together. Microhydro is a very rewarding form of renewable energy in terms of what you get from what you put in, because in most cases it runs for a much larger percentage of the time than solar or wind. I have designed and installed numerous systems over the last 20 years. I would use one myself if I had a suitable site!
In the UK it is possible to claim a “feed in tariff” for hydro power. See this page for details. I can advise on the technical aspects but I am not strong on the institutional stuff. I am more of an off-grid specialist and most of my customers are off-grid, either here in Scotland or around the world. I can design and specify everything you will need and also supply much of the extra stuff at competitive prices. While it is also possible to claim feed in tariffs in an off-grid UK system, I don’t know of anyone who bothers to do this. I can advise on the technical requirements.
