Usage of solar energy in Kenya has proved to be the most economical and beneficial power solution; capable of saving money on household electrical bills while protecting the environment. With more than 35,000 solar photovoltaic (PV) systems being sold each year, Kenya has a thriving solar industry. Thanks to the growing interest in solar power, both local and international companies have been keen to invest into the lucrative sector. Ubbink is expected to manufacture about 30,000 KEBS certified (Kenya Bureau of Standards) solar panels per year – particularly for small solar systems. On its part, Eight19, a UK-based company that deals in solar electricity, recently launched a portable solar energy system in Kenya to provide pay-as-you-go solar electricity.
The system, known as IndiGo, comprises a low-cost solar panel, a battery, an inbuilt USB mobile phone charger and a high efficiency light emitting diode lamp that can supply around 5 hours of light from a single day’s charge. Multinational organisations have also been at the forefront of promoting the use of solar energy in Kenya.
The system consists of 4,000 modules and promises to produce 750,000 kilowatt hours of clean solar energy annually – way more electric energy than will likely be consumed by the building.
Environmental-friendly: They do not pollute the environment in any way, thus paving way to a greener and better environment. First establish whether you have sufficient wind in your area to make an installation viable.  You will need specialist tools to gauge this  accurately and you may choose to hire someone to do this for you.
Find out how much energy you currently use so you know what size turbine to consider.  Your current energy provider can help you interpret your energy bill. Do a basic energy audit and see if you can insulate your home better to reduce energy consumption. It is still worthwhile doing some research into home wind turbines even if you employ a commercial supplier to educate yourself as to the suitability of the products that may be recommended. Liquid batteries are being touted as superior because they are cheaper to create, last longer, and their electrodes allow the liquid to absorb large quantities of energy quickly.
Small domestic installation use a bank of batteries, often in series, to provide backup, as this video shows. The European aim is to build handball size storage facilities, to store sufficient power for up to 2000 households overnight. Dommelvalley Green Power installation of a 1.8kW Skystream Wind Turbine in Utopia, Ontario, Canada. The cost of energy has encouraged Dr Fernandez to move to windmills to generate power to become more self sufficient, and here he discusses his use of small wind turbines. Interest in small wind energy is on the rise in the US, as people are looking for ways to seize control of their own energy supply. Where you place your home wind turbine is vital for the success or failure of your project.  You need to do extensive investigation on the amount of wind available and the speed of that wind.
Towers to support your home wind turbine are a major consideration and should be as tall as possible.
In terms of payback time domestic wind turbine installations and in particular DIY installations, offer better payback times than say, solar. Wind turbines arrived in the wake of the introduction of electricity and  they represent the latest and most exciting use of wind power.  As small–scale wind systems for home use have developed, the interest in the DIY potential of such systems has also increased. In principle, home wind turbines of an appropriate size can, or at least should be allowed to be installed anywhere; at the home, on the farm, in your rural garden, by your caravan, on your boat. Further, as is the case in some countries, you may not be allowed to install a larger wind turbine on a DIY basis. So what size turbine are we likely to be allowed to put, where, and how much is it likely to cost?
If you want to power a country home, again a minimum requirement would probably be a pair of Bergey XL.1 turbines working in tandem. My own favourite system is at a medium sized farm house, one that I had some involvement in, in Ireland. It is not unusual for a homemade wind turbine system to have more than one wind turbine involved.
Average manageable size turbines for home installation would be in the 100 – 1000 watt range. Marlec’s FM1803 turbine is also a good turbine example at the lower end of the scale. At the high end of the same scale we have the ‘Bergey XL.1, from a well established and highly experienced wind turbine manufacturer.
Turbines is this range all make noise in one form or another, be it a ‘swishing’ or a ‘slapping’ sound, especially at and above their design wind speed. Nonetheless all these turbines lend themselves perfectly to any homemade wind turbine project and installed in compliance with the manufacturers recommendations will give many years of consistent power output in all weathers.
Having studied the site location issues and being satisfied that your site is favourable for a home wind energy project, we can proceed to the selection of components. A host of websites give the impression that ‘almost anyone’ can build a wind turbine, many of them with their ‘buy my plans’ and similar sales agendas. Almost all wind turbines aimed at the home wind energy market are configured for 12 or 24 volt DC battery bank charging.
Next comes the decidedly important steel guy wires for tower support and for this I would ideally head to a boat yard and source premium quality stranded wire used for masts. Hardware stores can be a great source for fittings, fixings, wiring, fusing, multi-meters and tooling etc. The question often arises as to whether there are distinct power output differences between a reputable commercial turbine and DIY turbines. Whilst the use of wind power has provided man with energy and power in some form or other throughout the ages, to day there are three main categories of wind machine in use to serve our needs.
In pursuit of this interest, the enthusiast soon learned that there was more involved than simply erecting a wind turbine. As with most technologies for the home what one is prepared to invest will decide how successful the project is likely to be. Being exposed to, and harnessing the power of the wind, installation sturdiness needs to be given serious consideration. Like Germany, Western Washington is cloudy a good portion of the year, yet we can learn from its example.


Western Washington receives more hours of sunlight a day than Germany, and thus could be producing much more of its electricity needs from solar.
Aside from not charging sales tax on electricity-generating equipment, Washington state and the federal government also have other financial incentives to encourage sustainable energy. You can get started with a single-panel solar photovoltaic system and grow the system in the years to come as your budget allows.

Thomson Reuters optimistic vision looks little like that, thanks to a reliance upon scientific innovation that hopefully comes true.

Then we’ll present diagrams and discuss photovoltaic solar, solar hot water, and concentrated solar power. Solar power (electricity) is produced in two ways: by direct transformation of solar energy into current through photovoltaic panels (solar PV), or by the concentration of solar energy to create steam and drive a turbine (concentrated solar power). Most homeowners don’t know that residential solar panel systems are grid-tied, meaning that there is no backup battery system involved. Passive solar refers to any structural design element that converts sunlight into usable heat.
Concentrated solar power, or CSP, works by using an array of lenses or mirrors to focus a large area of sunlight (solar thermal energy) onto a small area.
Get Your Dose of Solar FactsWe are just entering the era of Solar Energy, but with less than 1% adoption in the United States, we have a long way to go. Solar Energy Facts is here to help you dispel myths, learn more about home solar, and decide if solar panels are right for your home. One such companies is Ubbink East Africa Ltd., which is currently putting up a Sh250 million solar panel factory in Naivasha. The German Energiebau Solarstromsysteme GmbH company has, for example, installed what is said to be Africa’s largest on-roof photovoltaic solar panel for the United Nations Environment Programme (UNEP) in Nairobi. This ensures a stable grid quality output without power fluctuations around the clock, daily. Once the installation of the necessary equipment is done, the electricity produced by the generator turns out to be available for free.
If your site is among trees or surrounded by steep hills, it is unlikely to be useful for wind power.  It is best if your site is flat or with hills that are far away from trees and other obstacles.
BUT, take into account that with very active moving parts and towers dependent on, and subjected to the harshest of wind conditions, the maintenance cost factor will be far greater. One or more Bergey XL.1, 1 kilowatt turbines is a good choice for a DIY wind power project on a farm, to supply outhouses, barns etc with power.
Cooking is done with gas, heating by two wood and peat fired stoves, (in turn feeding four radiators) and ‘air conditioning’ provided by open windows and the occasional use of fans. At the low end of the scale the ‘Air-Breeze’ is one of the most popular and efficient small turbines on the market to-day. With a rotor diameter of eight feet it is rated at 1,000 watts at a design speed of around 25 miles per hour.
If the turbines are installed a proper distance from a residence, this should not present any real problem. There is no need to consider ‘kits’ for the general component requirements for your home wind energy system, and no real cost saving in doing so, except perhaps at micro turbine level. Failing that a construction yard serving utility and telephone companies is also likely to have sound quality, (if thicker) stranded wire. To day they represent the latest and most exciting use of wind power – and as small–scale wind systems for home use developed, interest in homemade wind turbine potential went hand in hand with it. As with solar, important site considerations have to be considered; the most important being the site’s exposure to the wind.
You are likely to get mixed views from different officials and in the writers experience your will rarely get the same answers from the different local authority offices you call on. On the contrary, a cloudy day provides sufficient diffuse light for a solar panel to produce electricity.
Now is the time to take advantage of the incentives, before the sun sets on these great opportunities. Solar thermal and photovoltaic power will get thinner than ever, enabling creative placement on pretty much everything one can think of, thereby energizing the phones, homes, cars and lives of 2025’s ubiquitously internetworked populations. Exciting solar power innovations are the flip side of dystopian global warming discoveries: Both are exponentially occurring at light-speed, with more data being accrued by the day.
Barely five years ago, anyone who wanted to go solar had to shell out thousands of dollars.
By 2025, it explains, we will be routinely testing teleportation, mapping DNA, detoxifying cancer treatment, using cellulose packaging, electrifying our fleets, downsizing Type 1 diabetes, ending food shortages, declining dementia and digitally connecting everyone everywhere to everything. Thanks for visiting!Solar energy production encompasses several power sources, both passive and active.
The easiest way to think about these is: am I using solar energy to heat water (solar hot water and CSP) or am I converting sunlight directly into electricity (photovoltaic cells)? Solar energy in the form of light hits the solar panel, which excites electrons in the panel and creates an electric current.
Current supplied by the solar panels either flows into the home or into the grid through the home’s electric meter. This crude but effective diagram illustrates how simple design can have substantial impacts on home heating. A solar collector concentrates the sun’s rays to heat water, which makes a closed loop through the heating tank. Most CSP systems work by heating up water which, in the form of steam, drives a steam turbine and produces electrical power.
These systems focus a large amount of sunlight onto a small photvoltaic area–sort of like a mini solar panel.

So, the owners have a potential rated output of just 1 kilowatt, which generally gives them 2-3 kilowatt hours per day – more than enough to cover their requirements, and incidental needs that may crop up. First versions of it were produced in the early nineties and it has developed and progressed to become the most often sighted small turbine on land and sea. It’s a powerful machine for its size, well able for winter storms and like the ‘Air Breeze’ offers relative ease of installation in your own homemade wind turbine project. Weighing in at 104 pounds, assembly and installation is manageable but more manpower input and care is required .
An inverter is then used to convert the stored energy to 110 or 220 volts AC for household supply. But obviously more specialist suppliers are best for control systems, quality DC breakers etc. The commercially produced turbine will almost always outclass the DIY turbine, even if only on its weather proofing features. I am opposed to commercial wind-farms for many reasons, but mainly for their negative impact and visual pollution of our commonly owned landscapes and seascapes. If objections are raised they are most likely to relate to visual and noise considerations, so if the turbine is sited too close to a neighbour, bear in mind the possibility of a complaint to the local authority from that quarter.
The writer has seen DIY wind turbines disintegrate – and in one case, an entire turbine head catapulted 200 feet from a freestanding tower. As a consumer specialist, I write articles and blogs to help people make smart consumer choices. Support for this argument, according to Thomson Reuters, is indicated by the fact that Fabrication of novel heterostructure of CO304-Modified TIO2 nanorod arrays and enhanced photoelectrochemical property is the most highly cited paper of the last two years. The current created by the solar panel is direct or DC current, and it flows to an inverter box which converts it into alternating or AC current (this is what’s used by all of your appliances and the electric grid in the United States). The hot water is passes into a tank that contains a heat exchanger (usually used in conjunction with the hot water heater already installed in the home). As heat is exchanged in the tank, the water is pumped back up to the solar collector (determined by a controller unit).
It’s easy to confuse CSP with solar photovoltaics, but photovoltaics transfer solar energy directly into electrical current, while concentrated solar power transfers solar energy into a carrier (water) in the form of heat.
However, compared to standard solar panels, CSV systems are typically much cheaper to produce since the use of expensive parts (solar cells) are minimized. In fact if your back garden is in a housing estate, you will probably be allowed no more than a mini turbine – at a push. Equally standard air-conditioning units should be counted out; and to further enhance you cost effectiveness, cooking ideally should be done by gas. Having two or three turbines allows the use of turbines of a more manageable size and weight; the bigger the turbine the greater the weight, rotor diameter etc. With a rotor diameter of four feet, it is rated at 160 watts at 28 mph, with an impressive start up speed of just 6 mph. All in all, this wind turbine is a powerful battery charger and is perfect for small off-grid homes and the like. Have the yard make up the approximate wire lengths you require, complete with professionally crimped eyelets at one end for shackling to sleeve anchor points on the tower. On the other hand I find the privately owned small home wind energy turbine both aesthetically pleasing and very comforting. A flat or elevated open area is best with trees and other obstacles being well away from the turbine. In the summer this type of home will stay cool, while winters will provide plenty of heat–all without any additional energy input. My request: could you please compile many more diagrams that could be suitable for users (students, teachers and trainers) at different levels and with relevance to other regions of the earth. So DIY wind power is not always as simple as it sounds as sometimes the application mechanism and associated ‘red tape’ can be more exhausting than the installation.
The truth is that whilst on the surface, officialdom won’t be publically seen to discredit your quest for clean energy it still does not want you to be independent of the ‘system’. Then of course you have the additional costs for your tower, batteries and ancillary equipment, which could almost double your outlay, especially if a quality inverter is involved. So, carefully evaluating your needs, and working towards optimum energy efficiency is directly related to keeping you system cost down, and you sense of satisfaction up. It is an ideal start-up turbine for the small home and lends itself well to ‘modularity’ in that one or two others may be added with ease as need, time and funds allow.
How often I read: ”just nip on down to your local scrap yard and pick up your parts………!” Sounds so easy?
Galvanised steel pipe or scaffolding is the accepted ideal, with a diameter ranging from 2 to 6 inches depending on the turbine make, size and weight. Good quality wire bulldog grips (2-3 at each end) may then be used at the ground anchor ends to allow for adjustment, particularly if a tilt-up gin pole is to be used. This can be bothersome and is one reason why I would never install a larger turbine on a house roof. The biggest consideration in having multiple turbines is, of course that you always have a standby if one turbine fails or needs inspection.
For most of us, there is more than enough DIY work on the tower, the careful assembly of the purchased turbine, putting it all with together with care; and then successfully erecting it. Because you are dealing with wind and likely strong wind, wind turbines need to be sturdy and well secured. Yes, the apparent story behind the restrictions is often more than the real story behind the restrictions. An added incentive is that ‘economy of scale’ losses, in wind turbine cost factors are not excessive. I would never consider a roof mounting, but a tower fixed to the side of a barn with sound U bolts is not a bad idea. If you are constructing your own tower, I would check with a builder and engineer- there is no point in investing in an expensive turbine, only to have the motor blown off its housings or have the entire tower collapse in a gale.
