Solar panels hold a wealth of benefits, both for individuals and for the world at large. Economically, solar panels promise to lower the cost of electrical power. Environmentally, solar panels can give us cleaner power, sustainable power that will not require further damage to the environment. Solar power can reach remote areas. It can carry education, or urgently needed medical information.

The effects of clouds on a solar panel, though, might diminish those and other promising benefits.

The effects of clouds on a solar panel might make it far less efficient in certain parts of the world and at certain seasons.

 

For that reason, people who are considering solar panels for their homes are often heard to ask: will clouds affect my solar panels?

Will Clouds Affect My Solar Panels?

Clouds do affect solar panels. The amount of power your solar panels can produce is directly dependent on the level of light they receive.

In full, bright sunlight, solar panels receive maximum levels of light. During those “peak” sunlight hours, your solar panels will produce power at their maximum capacity.

When clouds cover the sun, light levels are reduced. This does not shut down power production, however. If there is enough light to cast a shadow, in spite of the clouds, your solar panels should operate at about half of their full capacity. Thicker cloud cover will reduce operations further. Eventually, with heavy cloud cover, solar panels will produce very little useful power.

The Good News!

The effects of clouds on a solar panel can be surprising good, however. Incredibly, your solar panels will put out their ultimate amount of peak power during cloudy weather!

As the sun moves into a hole between the clouds, your solar panels will see something wonderful. They will see full direct sunlight “plus” reflected light from the clouds! They will drink in more energy than they could on a cloudless day!

The effects of clouds on a solar panel could then produce peaks at or above 50 percent more than its direct-sun output!

Meeting the Challenge

There are ways to meet the cloud challenge.

1. If you often have clouds in the afternoon, but mornings are clear, aim your solar panels slightly toward the east.

2. Be sure you use a large enough battery system to maximize the amount of power stored for use when the clouds arrive.

3. Make sure your controller has plenty of headroom over the rated panel output power so that it can absorb the surges when the sun reflects off the clouds.

Those tricks and more are practiced in cloudy regions of the world where people have sprinted far ahead of the United States in their use of solar panel energy.

 

Effects of Clouds on a Solar Panels in Germany

Germany is typically a very cloudy country. Read about the climate of Germany, and you will find that it is “temperate and marine; cool, cloudy, wet winters and summers; occasional warm mountain (foehn) wind” according to Nation Master’s website.

In spite of its cloudy climate, though, Germany is by far the world’s biggest user of solar panels. If you lived in Germany, you could sell back to the main power grid all of the excess electricity produced by your solar panels. Why would I even care in such a cloudy climate? If clouds affect my solar panels too much, I would not worry about selling back to the main grid.

In 2006, Germany opened the largest solar park in the world. Germany also has Europe’s most modern solar housing project a solar village of 50 solar houses that produce more energy than they use!

Will clouds affect my solar panels? Even if I lived in Germany, the effect would not be enough to forego solar power.

Tip: There are few places that are so consistently cloudy that solar power is out of the question. Improvements are being made constantly, and even solar panels small enough to fold into a briefcase can produce helpful amounts of power.

Solar Helmet Hits The Scene

The Fraunhofer Institute team is probably the first to make a helmet that can harness energy from the sun to generate green electricity. The helmet is currently at the prototype stage. A solar panel curved in the shape of the helmet is installed. The device embeds a lithium polymer and acts as a charger for the skier’s portable devices such as a mobile phones or an MP3 player for example.

 

 

 

 

In a second step, the team will transform the helmet into communication equipment. In other words, it will connect the smartphone via Bluetooth and will act as a handsfree set. The helmet will be equipped with a microphone and an earphone. A glove equipped with high-tech buttons and OLED display goes with the helmet and can control it.

The project is in collaboration with a German company named TEXSYS. The helmet looks promising, especially in its final version.

Renewable Energy Discounts For Schools

In Germany, many schools have solar panels to cover part of their energy costs. However, their operation and use are rarely integrated into the curriculum. The Federal Ministry of the Environment (BMU) has decided to develop this educational potential by offering “solar support packs” which include an array of real-time display of energy produced by the panels as well as a recording device that transmits data to the computer network of the school, thereby making them accessible to students. These technical installations and other measuring devices installed by the German Society for Solar Energy (DGS eV), are accompanied by educational materials designed by experts from the Independent Institute for Environmental Issues (UfU eV) of Berlin.

 

The Minister pointed in his speech that “the turning point energy is a community and a generational prject: with programs like this, it is possible to wake up the interest and the enthusiasm for the potential of renewable energy” . With these facilities, students can indeed receive more concretely the energy from the sun.

 

Already 600 schools and training institutions in Germany have been equipped with boards that integrate science courses to the data received. At the end of the project, one tenth of schools with solar panels should be provided with the complete package.

 

The project is part of the “Climate protection in schools and training institutions” action program and is funded by the National Initiative for Climate Protection.

ABOUT WIND POWER

Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth’s surface, and rotation of the earth. Wind flow patterns are modified by the earth’s terrain, bodies of water, and vegetation. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity.

The terms wind energy or wind power describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.

So how do wind turbines make electricity? Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity.

Types of Wind Turbines Modern wind turbines fall into two basic groups: the horizontal-axis variety, as shown in the photo, and the vertical-axis design, like the eggbeater-style Darrieus model, named after its French inventor.

Horizontal-axis wind turbines typically either have two or three blades. These three-bladed wind turbines are operated “upwind,” with the blades facing into the wind.

Sizes of Wind Turbines Utility-scale turbines range in size from 100 kilowatts to as large as several megawatts. Larger turbines are grouped together into wind farms, which provide bulk power to the electrical grid.

Single small turbines, below 100 kilowatts, are used for homes, telecommunications dishes, or water pumping. Small turbines are sometimes used in connection with diesel generators, batteries, and photovoltaic systems. These systems are called hybrid wind systems and are typically used in remote, off-grid locations, where a connection to the utility grid is not available.

Solar Energy: It’s Not About Solar Panels Only

Wanting to save energy is always a good idea. Indeed, electricity generation, according to the methods of production, can be added to the list of factors that deplete the planet. The financial aspect is also taken into account, and electricity prices, like most other energy sources (especially fossil fuels like oil, which we derive most of our fuels) end to always increase.

In response, more and more solutions are emerging; the most famous one is that of the purchase of photovoltaic panels. But even if subsidies are available to assist in this investment, this is an option that is only available to those who own a home that enables the installation of such panels. Tenants, living in apartments or whose roof exposure is not appropriate will not benefit. Fortunately, alternatives exist for those who cannot afford a photovoltaic kit.

The wind generator is a particular alternative for the proud owners of large gardens, but not only! Indeed, there are now small models that can be installed on the house roof to produce at least part of the electricity consumed by the household. Newer models are more productive while being quieter, and allow for constant use in particularly windy areas, even if they are not sunny.

But for those who cannot afford to invest in such facilities, there are still alternatives to save electricity on a daily basis. Ideas abound, and manufacturers creativity and competition offered u really ingenious gadgets and practices. For example, a solar battery, which is recharged by placing it directly in the sunlight, will charge many electronic devices such as mobile phones, mp3 players or even, for a little more powerful model, your laptop. By the same principle, you will also find battery chargers or laptops equipped by a solar panel. That said, the system of the outer solar battery is preferable since a single battery allows you to charge many devices as long as you have the necessary adapters. A solar backpack can also fulfill this role.

Besides photovoltaic electricity generation, there are other ways to utilize solar energy, for example by using solar thermal panels, which can heat water in your home, or devices like the solar cooker allowing you to cook entire meals with nothing but solar energy, for a much healthier food than the one you can get with a barbecue, well known for introducing harmful elements in food!

8th March 2012 Solar Energy: The “Grandmothers” Who Decided To Illuminate 600 Households

After spending six months in India where they received training on solar energy techniques and technologies, “grandmothers” have decided to put their talents into local development. Thus on 1 March 2012, they launched the lighting projects of 600 households with solar energy. It was in the village of boala, about fifty miles of Kaya, in the Namentenga province.

The purpose of these six projects, costing a total of 375 million CFA francs, is to allow each willing household to supply solar energy for their fixed lamp, solar light lantern and a socket (for charging mobile phones) etc.., according to the Minister of the Environment and Sustainable Development, Jean Kouldiaty, head of the launching ceremony. The “grandmothers” union formed, will have to install and manage small units of solar energy in their villages while maintenance costs of solar equipment will be managed by communities. “This training allows these women to become role models for youth in the community, both girls and boys”. Added the Minister for Kouldiaty, “My wish is to see this event as a springboard to strengthen state efforts and technical and financial partners and promoting the use of alternative energy by creating a training in solar energy at schools.”

For Pascal Karorero, the Resident Representative of the United Nations Development Program (UNDP) in Burkina Faso, “this initiative is of particular interest for our organization and the UN.” He said the lighting of 600 rural households contribute to the preservation of biological diversity, children’s education, promotion of income generating activities and reducing the rural exodus. “The initiative also aims to achieve three interrelated goals for 2030 which are universal access to modern energy services and doubling the rate of improvement of energy efficiency and the share of renewable energy in the energy mix, “said Mr. Karorero.
