Tenesol global provider of solar-owned giant TOTAL and EDF, has contributed to the creation of one of the French proposals at the International Solar Decathlon competition (SD) 2010. 20 universities around the world compete with the objective of designing and building an ecological house-sized, which runs entirely on solar energy. Throughout the contest, the house is inhabited. This helps to highlight the latest innovations in effective, attractive and affordable for the sustainable development of the future.

For over 26 years Tenesol imagines, designs, manufactures, installs and manages the systems of production and consumption of solar energy (consumption on isolated sites, general power grid directly connected, hot water sun) for its customers worldwide.

In addition to photovoltaic panels, Tenesol also provided all cables and an integrated control system that measures the amount of electricity produced by solar home. The company also made available to students a project manager who works alongside them and provides any assistance. The team was able ENSAG consolidate their knowledge of photovoltaic technology and learned to get the best possible results.

ARMADILLO BOX: THE BOX IDEAS

The design of the Armadillo Box came from the results of a European research project dedicated to passive houses in hot countries. It is based on a compact structure and aims to reduce the need for heating and cooling of the seasons. The building includes a number of new technologies for sustainable development. Its characteristics are as follows:

* 97 photovoltaic panels in total, spread over an area of 102 m2 with a capacity of 15 kWp, are integrated into the roof structure and shading. The system is connected to the network and supports all of the electricity needs of the house.
* A mechanical ventilation system Dual-stream runs through the whole frame of the home. A single pump is used for heating and cooling of the housing. This system also produces hot water, depending on sun exposure.
* The housing is completely isolated and all the kitchen equipment belong to the energy class A.
* The house is fully automated: all equipment and accessories (including curtains) are controlled by an automation system
* The building is made of natural materials and recyclable materials such as wood, recycled steel and earth.

The students have built two houses Armadillo Box for this project. One of them will be used for the contest DS 2010 and the other will be presented in the solar village of INES, the premises of the institute, Le Bourget du Lac. Thus, it would receive wider dissemination.

Solar Decathlon

SD is a biannual event organized since 2002 by the American Department of Energy in order to inform on solar energy, educating the public about this issue and encourage the use of such energy. For this 2010 edition of Solar Decathlon leaves for the first time the territory of the United States, since the event took place this year from June 10 to 19 in Madrid, Spain (read our article “).

The prototypes of houses must operate solely on solar energy, be connected to the network and use technology to lower energy consumption. Ten trials to assess the houses (hence the name “decathlon”). SD represents a key challenge for Tenesol. The company recently expanded its business from individuals. Now she sells solar solutions directly on the French market and is expanding distribution of its consumer products in Europe.

A simple points of failure can plague a solar home system with a central inverter.

Consider a centralized solar system as a string of Christmas lights are run in series. If one bulb goes out, the rest goes with it. Even a shadow of a group in a table, you can drag the energy crop of the entire network down. Enphase Energy has established the claim of being the first to produce a microinverter system available for commercial or residential. According to my friends in the solar industry, “[Enphase systems Microinverter] take the world by storm the sun.”

Microinverters reduce the volume, space and sound of traditional investors. A microinverter up under each panel photovoltaic panel converts DC to AC and links directly to the existing wiring and electrical panel in the house. This saves the cost of copper wire of high caliber, and the task of leading his garage (or other central location) of photovoltaics. With a few dollars per foot wire amounts to a lot of money in labor and materials. It may supply the uninterruptible power to the laptop battery.

According to the site Enphase microinverter energy that can improve the performance of photovoltaic panels by 5% -25%. The advantage of a UPS by the photovoltaic panel is the individual panels continuous production, although a group of the table is shaded or damaged. In the traditional table where all the panels are interconnected, the less effective the group takes the rest to their level.

Microinverters reduce the risk of total failure significantly by isolating the elements of the system. Enphase also argues that if a single investor is turned off, the repairs can wait until the routine maintenance is required, saving the owner of a large amount of hair at the end.

Critics say the unit is more likely that some of the equipment failure (next to the battery if you believe an application outside of the network). They argue that increasing the number of investors could lead to higher costs of maintenance of the owner of a house. To minimize premature failure if the product you are considering purchasing met testing highly accelerated life (HALT) and Highly Accelerated Stress Screening (HASS) testing standards. Enphase microinverter wrote this review.

In a little over a week die of the state solar rebate program in Florida would end. 30th June is the date of execution, except for some last-minute miracle. Small solar companies already feel the pressure to drop fast projects and contractors of the ditch to the north, to states such as Georgia and South Carolina that have a better political environment for solar energy.

Mourning the death of the Florida Solar Rebates

Florida Solar Energy System Incentives Program was adopted in 2006. It provides a generous $ 4 per watt rebate for the solar home power of up to $ 20,000 for the photovoltaic (PV). This means that a 5,000 watts (5 kW), which costs about $ 40,000, would receive a healthy dose of subsidies for a refund of state and federal tax credit. The claims of the latter 30 percent of the original cost – about $ 12,000 in this example – and the state would pay out the maximum $ 20,000, which means that 80 percent would be subsidized by means of a 5-kW Solar. That may replace 100 pics laptop battery.

This is easier for contractors, sales in the Florida sun, made evidenced by the fact that the financing will not last for long the rebate program, even with the help of the Recovery Act of money. But the expiration of the Florida Solar rebates have very negative impact on businesses. Even small systems eligible for the rebate – 2 kW – get a bonus of $ 8,000 of the state, worth $ 15,000.

Certainly, these discounts are disproportionately high. It is because the agenda in 2006 and since then has been developed PV prices declined significantly. Entrepreneurs in Florida Solar understand, but by the complete abolition of the state solar rebates are disappointed and went to a party, a bar of credit to $ 2 per watt, with the decline in the price keep PV. Unfortunately one years, died of his revised budget for all states, including Florida and an invoice for a renewal discount prospective in committee in the legislature of the state.

Solar incentive programs still available:

It is a taxpayer funded 24,500,000 U.S. dollars in cash profit group to use the fund for energy saving initiatives.
Energy efficiency and conservation block grant, the municipalities apply for grants for solar energy and finance other initiatives efficiently.

Florida’s law also allows local PACE programs clean energy projects funded property tax increases due to the individual.
JEA (formerly Jacksonville Electric Authority) offers rebates for small houses with new energy-efficient and up to $ 800 for solar water heating.

But all that the loss of state subsidies that bring this period is likely to offset Florida’s solar industry to a standstill. In some states, utility companies charge the case, but the State tends to renewable portfolio standards requiring utility companies have to maintain a certain percentage of renewable energy. In Florida, JEA has only the program. Therefore, until an RPS or reduced further legislation passed, solar energy, with jobs and clean energy that comes with it, is waiting in the Sunshine State.

With escalating power bills and so much talk of renewable energy millions of people are thinking about solar power these days. Harnessing the sun’s energy makes sense because it is clean, green, and saves money in the long run as laptop Battery. But the reality is that the cost involved with installing panels and collectors is still out of reach for the vast majority of homeowners. Fortunately there are some cheap and easy ways to make the sun work for you.

Use Passive Solar

Passive solar means simply using or blocking the sun’s rays to heat or cool your home. This means that using your window coverings wisely can save you a ton on your power bills. Simply closing or angling your blinds to keep direct sunlight out can drop the interior temperature by 10 degrees. Try closing the window coverings on the south side of your house when you leave for the day during the summer months. Without the sun’s hot light shining in the windows, your air conditioner won’t have to work as hard. And in the winter of course doing the opposite can help heat your house. There tons of great looking blinds , awnings, and window films to help you harness or block the sun’s powerful rays.

Use Solar Exterior Lighting

Lighting the exterior of your home used to be tricky because you had to find a way to get power to the lights. But with the advancement in renewable power technology, these has gotten a lot easier. Solar garden lights, security lights for HP 530 Battery, and area lights now come completely integrated with panel, battery, electronic eye, and lights. Installation is usually as easy as hanging a picture and the prices start at less than $50. So whether you are trying to put some accent lights in your garden, shed some light in your tool shed, or trying to brighten those dark steps, lights powered by the sun are a great alternative.

Get Portable Chargers

These days we carry so many electronic devices around with us it kind of feels like we are a walking Radio Shack . The hardest part is figuring out how to keep these things charged. Now there are cool-looking portable solar chargers that will keep your iPod or blackberry running in a pinch. They are lightweight, folding, and very durable to handle the rigors of travel and outdoors situations. And if you are indoors and in need of a quick charge most of them will work by simply them putting near a window.

Decorate Home and Garden

For your outdoor spaces, solar fountains lend a soothing touch to any setting. All they require is a little water and a sunny spot and they can surround you with pleasant sounds or keep your pond aerated in Toshiba PA3399U-2BRS. Solar lamp post lights lend a nice touch to any entry area and tell your arriving guests you have good taste and care about the planet.

Get a Plug and Play Kit

If you need a small power source for your cottage in PA3465U-1BRS,, RV, or to take with you into the wilderness, there are great options out there. There are solar power kits that include the panel, the electronics, instructions, and all the wiring you need to get started. For example, a kit could power a little stereo, light, and charging your phone down at the boathouse or out in the barn. Or they can keep your RV battery charged as you travel around the country. You’ll need a screwdriver, the ability to follow instructions, and a sunny place for the panel. Many of the kits start at less than $100 and for $500 you can get a nice little system and expand it later.

If the EU wants to maintain European leadership in photovoltaics, EPIA urges the European Commission and Member States to implement urgently the implementation of the plan for the initiative of the European Solar Industry by introducing effective financial mechanisms, as well as increase significant public budgets for R & D. While the SET Plan is being discussed for more than three years, other governments in Asia and the United States continued its public support for R & D for their industries, which directly translates into more manufacturing costs low.

However, the R & D is not the only ingredient, increased production capacity is as important as R & D in order to achieve economies of scale and therefore public support (in the form of tariffs) is still needed to able to assume a stable growth market.

“R & D is not sufficient by itself and has no impact on competitiveness if not accompanied by an increase in volumes and market development. The 40% decline in prices that occurred last year and 50% of the last two years confirms that political support is still needed to achieve the economies of scale through increased production, “said Virgilio Navarro, Vice President EPIA and CEO of ATERSA.

The above measures should be accompanied by improved access to market regulation, strengthening the distribution network and an increase in transmission capacity.

EPIA and the European Photovoltaic Technology Platform congratulated the European Commission and Member States for the efforts undertaken to strengthen and coordinate all efforts at European level in the R & D, and encourages them to keep all existing support for market growth to enable photovoltaics to be competitive in the short term.

With over 200 active members representing the entire value chain, the Association of the European Photovoltaic Industry Association (EPIA) is the largest industry association in the world dedicated to the market of solar photovoltaic electricity.

EPIA’s mission is to provide valuable and distinctive services, under the tight control of a single voice: the voice of the photovoltaic industry. The association aims to promote photovoltaics at the national, European and international, as well as assist its members in developing their businesses, both in the European Union and other foreign markets.

Photovoltaic Technology Platform is an initiative to mobilize all the actors sharing a long-term European vision for PV. The Platform is an independent and objective aimed to be the point of reference for the recognition of government representatives and policy makers. Platform’s mission is to develop a strategy and plan for education, research and technological development, innovation and market development of solar photovoltaics.

The European Photovoltaic Industry will invest around 740 million euros in R & D in order to achieve the competitiveness of all its segments.

The initiative of the European Solar Industry (SEII, its acronym in English) to be filed Thursday in Madrid at the European Conference on the SET Plan will contribute to reach 12% of the supply solar photovoltaic electricity demand by 2020 .

The Association of European Photovoltaic Industry Association (EPIA), the industry association world’s largest photovoltaic, together with the European Photovoltaic Technology Platform, presented at the SET Plan Conference held on 3 and 4 June in Madrid under the under the Spanish Presidency of the EU, the initiative of the Solar Photovoltaic Industry.

The Implementation Plan 2010-2012 announced that during the next three years will be required to invest 1.2 billion euros in R & D to optimize production aimed at reducing costs and improving the interface between the grid and photovoltaic systems.

These are the first steps designed to achieve in this decade, competition in the selling prices of electricity for residential and commercial sectors and in areas with high irradiation and even competitive with conventional fossil fuels for industrial applications. The investment would reach exactly 1,235 million euros, of which nearly 60% will come from the private sector, while the remaining amount has to be balanced between the European Commission and EU Member States.

Since last year, EPIA and the European Photovoltaic Technology Platform have worked together with the European Commission and representatives of Member States in the initiative. As a result, sixteen Member States have expressed their commitment to supporting the Photovoltaic Solar Initiative of the European Industry has identified three common areas of high priority in the short term: advanced manufacturing processes for all photovoltaic technologies aimed at reducing costs and improve efficiency, development of building integrated photovoltaic products (BIPV) and applications to facilitate and reduce integration costs the same, and outdoor test concentrator photovoltaic technology. It was further agreed that in the long term, materials (including organic solar cells) and the development of intelligent modules for easy integration into the network will be the priority themes.
