Now that we’ve developed a complete representation of what we’re trying to achieve in designing solar power systems and have some education on electrical energy it’s time to do some thinking and some arithmetic to convert that into reality. That happens in two stages. One, we must identify what we are attempting to run and the amount of power that’ll use. After we decide on that, the second task is deciding what amount of panels and solar batteries will satisfy our needs once the system is built.

Dealing with an off grid project like the one I made, I’m just powering a subset of ordinary household things and appliances. These include a stereo, a computer, lighting, a water pump and so on. The first phase is to craft a list of everything you plan on running.

The next step actually calls for multiplication, just so you are aware. Understanding what you are powering is good, understanding the exact amount of electricity that requires is what you really need. There are plenty of resources on the internet for this at a general level. Build a list detailing every piece, its wattage and the amount of time each day it will need to be powered. Multiplying wattage times hours for every component gives a daily watt*hour total, then summing all the parts together arrives at the overall daily amount. This is everything we are interested in, total electricity consumption as a single amount, when you arrive at this spot every discrete piece being powered doesn’t matter anymore, however we will probably go back and adjust that list a couple times.

Now that we’ve got our total daily power usage number, we’ll have to be able to generate it. The first and most important factor is going to be in what location your solar setup is geographically. In the dead of winter at the North Pole, there isn’t any sunlight at all, but there’s still a fair bit in the Arizona desert. As I’m aiming to be in the southern US in the middle of the winter, I used the rough guess that I will be getting 5 hours of peak daylight every day.

In addition to that we need to design for cloudy days. I came up with a rough worst scenario that it’s rainy for 3 days back to back, and that cloud cover would cut solar input by half. This isn’t an exact science, and varies based on your battery bank size how much you can tap into them during stretches of low light, but simply round decimals are simpler.

In a DIY solar panel system the deep cycle batteries wind up being just as crucial to providing energy as the panels themselves. After the sun goes down, you need to be able to draw on a lot of the energy stored from the day to use your electronics. A set of solar batteries that’s too small will pose two problems. The first is that it’ll shorten the overall life of the solar batteries. Avoid draining your solar batteries below 50% of their total capacity. A repeated depletion of three quarters of the overall capacity might cause the solar batteries to lose capacity, not keep as much energy and have to be changed much faster. One other problem with a not large enough set of batteries is not harvesting the full amount of available solar energy. If it’s nice and sunny but you continually fully refill the solar batteries by mid afternoon each day, from that point until sundown you’re not storing any further power, it’s just waste.

The first windmills that were used in Holland for water draining are mentioned in written documents in the year 1414. Windmills designed for graining, have lived there 200 years before that. Read more about the history of this. The oldest identified documents that mentions a windmill are the privileges offered to the city’s bourgeois, in 1274. The feudal senior could give the right of building a windmill, to constrain the workers to move cereals to his windmill, and to avoid the construction or the planting of trees close to the windmill for being sure the powerful wind.

In the following years, windmills extended over Holland. Useless towers that once were employed for keeping gun powder were converted into mills. Yet the real progression of Dutch windmills happens at the end of the XVI century and the beginning of the next one. The windmills started to be used more and more to make all kinds of manufactures. They were built from heavy wood, brought in ships from heavily forested lands from around the Baltic Sea.

The cheapest source of energy for the Dutchmen was the force of the wind. Larger and stronger windmills could drain excessive amounts of water. That was incredibly important as the land of Holland was constantly in the chance of being drowned by water. As its territory was under the sea level, lots of great cities such as Amsterdam and Haarlem were threaten to be flooded. As an example of the power of the mills, in just one year, the Beemster Lake was emptied by twenty six windmills.

Across the year 1850, about 9000 windmills were operational in Holland, probably the greatest number that ever existed there. Subsequently, their number started to decrease. By the end of the XIX century there were only 2500 windmills left.

In 1920, an initiative for creating an association to protect the windmills was beginning to take shape. This association was launched in 1923, in Amsterdam. As result of a petition the Dutch society of windmills wrote, in 1924 a letter to the minister of Education, Arts and Science that emphasized the importance of keeping these monuments. Same letters were sent in 1930 and in 1939.

By the first of January 1961, an agreement has become successful and according to it, any person who maintained an operational windmill received a subvention from the state. Most of the times, a windmill owned by an old person, who can’t keep it in working conditions, is taken by the authorities and transformed into a cultural monument. Normally, it shelters a museum or it becomes a center of receptions organized in the respect of international guests.

Holland greatly owes its existence to the windmills, because, with their help, water was kept from flooding the terrain and can now hold a growing population.

When building windmills, people think about how to improve their efficiency. To do that, they examine the parts. The most vital components of a windmill are, certainly, windmill blades.

The very first thing to consider when talking about windmill blades is their number. The more blades a windmill has, the harder will be for it to rotate. The old ones used to have 4 very bulky blades. Many of them were use in grain grinding. Now, the most recent windmills are equipped with two or three blades.

The length is important as well. If a blade is longer, it covers a bigger surface when it rotates, therefore they can catch more wind with each rotation. This may contribute to extra torque. To protect the windmill blades we mustn’t forget about their surface. If we provide them with efficient maintenance, they will last longer and will also be more efficient.

Additionally, the shape of windmill blades influences their rotation. There are several different shapes of windmill blades: the flat, rectangular ones, the wing shaped types and the ones with both edges tapered to a slim line or both edges rounded like the ones of a plane wing. In the case of the horizontal axis windmills, the wing shape has proven to be by far the most effective one. The vertical axis windmills works very well with all the shapes of the windmill’s blades, but the greatest performance is given by the flat ones and the ones with both edges rounded.

About the material with which the windmill blades are made from, if we think about the old ones, they were usually made out of wood. Although those windmill blades are made of wood, their structure changed over time. They are much lighter now so that they can spin faster. A common material that brings a high performance due to its sharp edges and its light weight is carbon fiber. One more material that’s light, but also economical is PVC. It’s a synthetic material sometimes used for windmill blades. New substances are always being tested, in the hopes of finding a less costly, more efficient solution.

Windmill blades are continuously developing, although they appeared a very long time ago. At their early stages they were somehow inefficient, but people learned to improve them and to make the windmills a popular source of energy. A lot more shapes and materials have and will be for windmill blades and people begin using increasingly more this alternative source of energy which will not only save our money, but also our environment.

Vertical windmills are not such a new concept. In fact, despite that we’re accustomed to seeing horizontal axis windmills, the first windmills introduced were the vertical ones. The first effective types were invented in the 9th century, but their design has changed very much over time in order to get a higher efficiency from them.

Vertical windmills have several benefits. Among them is the low sound that they make. Horizontal windmills generally are very noisy, a fact that is proven by their settlements in non-populated or low populated areas with not so many habitats around. Because of their silent function, vertical windmills are most of the times used by humans for their homes, metropolitan areas or commercial buildings.

Another advantage that vertical windmills have is that they can capture more wind than horizontal windmills. Regardless of the direction from which the wind blows, vertical windmills can catch it and convert it into energy. We can’t say the same about the horizontal axis form windmills.

A vertical windmill is easier to maintain. It’s also secured to do it, also. We owe this to the truth that the position of the generator is at the ground level. Because it is in such a helpful place and simple to repair, we save a lot more time & energy when we give it maintenance or when we fix it.

Using the vertical windmills’ design also brings benefits for the birds. Birds sometimes fly into the horizontal axis windmill. From this point of view the vertical axis form is safer and there’re least possibilities for birds to fly into its blades.

Vertical windmills could also have a highly anesthetic look, as they could be adapted to the adjoining area. They don’t have a pre-established pattern to pursue when building them. You could find them in a number of shapes.

The most common vertical windmills are the Savonius & the Darrieus. The Savonius windmill is mainly used for pumping the water or for grain grinding. If you look at it from above, you notice that its shape is the one of the letter “S”. Contrary to the Savonius, the Darrieus windmill is used for generating electricity and not for pumping water. Its blades are in model of the letter “C”, providing it the aspect of an eggbeater.

We live in a world where the electricity is not only beginning to become more and more expensive, but we’re also becoming more aware that many sources that produce it are affecting the environment. Start thinking at building your own vertical or even horizontal axis windmill so you can save money and help save the Earth in the procedure.
