Caplor Energy Attends Ofgem Roo Fit Workshop

Caplor Energy Attends Ofgem Roo Fit Workshop
With the popularity of commercial sized solar PV continuously growing and the government reiterating their support for rooftop solar installations, Caplor Energy has been ensuring that we stay at the forefront of this expanding market. Solar PV installations that have a Declared Net Capacity greater than 50kW and up to and including 5MW require ROO-FIT accreditation to take advantage of the Feed-in Tariff (FiT). This complex and often time consuming process takes a number of months to complete and creates a large barrier to people wanting to access their FiT payments as soon as possible. To ensure that Caplor Energy is kept up-to-date on the latest ROO-FiT requirements and so that we are best placed to assist our customers through this difficult process we recently attended an Ofgem workshop. This is great news for those of you who are able to install commercial PV of this capacity such as on factory roofs, farm buildings and ground-mount systems. If you do choose to install a system greater than 50kW Caplor Energy will be here to guide you through the accreditation process. Caplor Energy are independently rated as a Top 10 UK installer for PV and other renewable energy systems and are Herefordshire's only NFU Farm Energy Service approved supplier.

Ignore The Detractors The Sun And Our Winds Are Already Making A Big Energy Difference

Ignore The Detractors The Sun And Our Winds Are Already Making A Big Energy Difference
"RENEWABLE ENERGY WORLD" this week feature an article with the title:

Renewables Provide 88% of New U.S. Electrical Generating Capacity in May 2014

Coming online were:


* two wind farms providing 203 MW
* five solar farms with 156 MW and
* one new biomass facility of 5 MW

The only fossil/nuclear additions were two natural gas power plants with 49 MW.

For the year, renewables accounted for 54% with 3,136 MW ("about three nuclear stations") of new domestic electrical generating input, but natural gas added 1,437 MW. Since 2012, renewable energy sources have accounted for 48% of new electricity, natural gas at 38% and coal at 13%.

On the other hand, a Dr. A. Cannara commented:


REMARKABLE DANCING WITH FIGURES! RENEWABLES: "ACCOUNTED FOR 54.1 PERCENT OF THE 3,136 MW OF NEW DOMESTIC ELECTRICAL GENERATING..." ONLY 3.136GW? THAT'S LESS THAN 1.5 TYPICAL NUCLEAR PLANTS. AND THE 54% RENEWABLES WAS "NAMEPLATE" OR AVERAGE CAPACITY? IF THE LATTER, REAL NUMBER, THEN LESS THAN 20% WAS "RENEWABLE".

The points are that the renewable contribution is still very small, and that the sun only effectively ("clouds, night, etc".) shines, perhaps, eight hours/day, and our winds sometimes stop. Of course, Alex Cannara ("left") is a nuclear proponent.

"The June 16 issue of TIME" magazine, however, was effusive about the growing potential of the renewables, titled:

"THE GREEN REVOLUTION"

To summarize:


* Over the past five years, wind capacity has tripled, while solar increased 16-fold.
* 165 coal-fired power plants have recently been ("or soon will be") retired.

"

* In 2009, the Energy Information Administration predicted that the U.S. wind capacity would reach 40 GW--WIND POWER HAS ALREADY PASSED 60 MW (equivalent of 60 nuclear power plants--but remember that the actual electricity produced is two-thirds less").
* This increase in wind power is the equivalent of taking 20 million cars off the road.
* Since 2009, the price of photovoltaic panels has DROPPED MORE THAN 80%!

" * Or, even more impressive:

* when I first began writing with Waqidi Falicoff and George Koide SOLAR/WIND HANDBOOK FOR HAWAII" ("which can still be had for 20 from Amazon.com") in the mid-1970's, the price of solar PV was 75/watt
* today, it is a hundred times cheaper: 75 cents/watt.

"

* Utility companies are corporate dinosaurs (cartoon courtesy of NC Warn"), for they are mostly clinging to what they now own, and are fighting decentralization of renewable sources, which will be inevitable, for distributed power is cheaper and better.
* Solar energy and wind power suffer from a lack of cost-effective energy storage, but fracked natural is changing the equation, and could well serve as the transition to a greener future.

"

* LED (light-emitting diode") lighting ("right") is finally getting cheap enough to compete with fluorescent and incandescent, for it is five times more efficient than incandescent bulbs, and lasts 25 times longer--the economic comparison with fluorescent today is debatable, but the trend is obvious--the LED market will zoom from 2 billion today to 25 billion in 2023, with lighting today using 15% of all the electricity generated.

"

* The end of coal is around the corner, for the seriousness of global warning will tax this option into obsolescence. Aside from Hawaii, the other 49 states use almost no petroleum for electric power generation because this fuel is already much too expensive and supply metastable. Hawaii's electricity comes almost all from oil and our rate is 309% higher than the national average. (Click on that chart to actually read it".)

"

* Already, Saudi Arabia has launched a 100 billion solar initiative and China has announced plans for 250 GW (that's the equivalent of 250 nuclear reactors") of wind and solar BY 2020. Air pollution in China cities can be 40 times higher than acceptable safety standards.

* When someday externalities ("adding the cost of pollution, security, etc".) must be included into energy pricing, the GREEN REVOLUTION for energy will prevail. When? Who knows? The fossil lobbying effort remains powerful, but even some Republicans are getting concerned. Just this week a bipartisan blue-ribbon panel of American leaders suggested that we've reached the tipping point. Republican chiefs George Schultz and Henry Paulson were among the members:

Solar Energy Home Systems



QUESTIONS AND ANSWERS

What is the best solar power energy product mostly use at home.?

Posted by pipoy


FREDRICK-BARRIER

A solar hot water system is an excellent way to make your home more "green" and energy efficient. The solar hot water system works in conjunction with your current hot water system and can provide up to 75% of your homes annual hot water needs. The solar hot water system pays for itself within 6-8 years. The automated system is virtually maintenance free and is rated to last up to 25 years.

Whats better than saving money on your monthly utility bills while making your home more energy efficient?

How to design a solar energy system?

Concerning the calsulation:


1-system nominal voltage is 12 v DC

2-system nominal current is 2 A DC


3-days of autonomy are 4 days

4-daily energy consumption is 288 Watt. Hour

5-daily anticipated peak sunshine hours are 4 hours


6-cable and circuit operation losses are 0.25 ohms

7-PV panel power is 18.75Watts

8-100 A rechargable battery.

I have done some calculation but i still need to get from you.

Thank You for answering.

FREDRICK-BARRIER

Can be used to decrease or eliminate energy costs, reducing our impact on the environment and saving people money in the process. If you wish to design your own solar electric system, it pays to be prepared.

Step 1-Determine whether you will need to tie your solar electric system into the existing power grid or you wish to design it for use off the grid. This will depend on your precise location and how near you are to a power line.

Step 2-Calculate how much sun your area gets, and whether there are any obstructions which may cast shadows on your solar panels.

Step 3-Perform a power load analysis to determine what your electric needs will be. The table provided at SolarSense.com can help you calculate your requirements (see Resources below.)

Step 4-Determine the output of the panels you wish to use (based on their capacity and how much sun they will receive), the battery you have in mind, and the inverter your home will require.

Step 5-Compare your expected panel output with the amount of space your solar panels will require, and then compare that to the amount of space you have available. This will determine how much energy you can reasonably produce with your solar electric system, and should be incorporated into your design.

Step 6-Prepare a contingency for those times when the sun does not shine enough to produce adequate power. If you are on the grid, it will mean paying for electricity through the power company. If you are off the grid, it will mean using alternate forms of electric power such as generators.

Step 7-Choose your components based on what you require. These will vary widely depending upon your circumstances, but will include the solar panels themselves, mountings and means of securing the panels, conduits and wiring, an appropriate battery or generator, and an inverter to convert the panels DC power to AC use.

How Much Green Home Energy Does An Active Solar Energy System Provide?

Posted by Sylvan


FREDRICK-BARRIER

Active solar energy can power 40-80% of your home energy needs. Anything less than 40% is not cost effective. Besides home heating, active solar is awesome for air conditioning, detoxification of contaminated water and thermoelectric power generation.

For maximum green power, position your solar collectors true south, tiled at an angle equal to your latitude plus 15^0. The best time is 9am to 3pm when the collectors receive the most sun rays. Its good for energy collection and optimum storage.

Will New Tariffs On Chinese Solar Products Give America An Edge

Will New Tariffs On Chinese Solar Products Give America An Edge
The good news? Solar energy is seeing massive growth in the United States.

The bad news? It still has an incredibly long way to go, but the future is bright.

In an effort to help the blossoming solar industry domestically, the United States International Trade Commission decided to slap some heavy tariffs on solar panels being imported from China and Taiwan. Originally, tariffs had been aimed at Chinese products, but was it was found that Taiwan was being used as a work-around of sorts for China to dodge the original tariffs, hence the new effort to place fees on products from Taiwan as well.

As Nasdaq.com reports, the fees sound fairly hefty - 165 percent on Chinese products and 76 percent for Taiwanese products. Given the relative advantages the Asian manufacturers have over American, namely cheap labor and heavy government subsidization, action needed to be taken to help foster growth in domestic production. There is a bit of leeway for Chinese manufacturers, however, as the tariffs do not actually effect every single company. The USITC works with each company on an individual basis, and takes different things into account when determining the actual tax level.

Factors that can play a part in that determination include the origin of raw materials, where labor is outsourced to, and what the end product hitting the market actually is.

There is a small but growing contingency of American solar panel manufacturers, including Solar City (NASDAQ:SCTY) and First Solar (NASDAQ:FSLR), all of which are set to benefit from the USITC's decision. New areas around the country are growing and becoming open to solar power as a result of improved technology and tax incentives, making the market ripe for investment. For example, places like the pacific northwest, which suffers from a reputation of constant cloud cover and rainfall, are attracting entrepreneurs and customers alike.

Naturally, the tariffs are designed to help spur on customers to make purchases from American manufacturers. The question is whether or not it will work.

"

Source: Solar Energy Industries Association"

The real question doesn't seem to be if the measures being taken to undercut Asian solar products will lead to an edge for American companies, but rather, when? The solar industry is seeing huge growth, and as can be seen in the chart above from the Solar Energy Industries Association, the next few years are expected to see a huge jump in installed solar capacity. That means a ton of business for solar installers and manufacturers of panels and components.

All of that increased capacity is coming at the beck and call of residential and commercial adopters, who have helped make solar energy one of the fastest growing energy segments in the country. By the SEIA's estimates, total capacity increased by 41 percent last year, and was the second-largest source of new electricity production.

According to Sayle Kann, senior vice president at GTM Research, these numbers are only the tip of the proverbial iceberg.

"2013 offered the U.S. solar market the first real glimpse of its path toward mainstream status. The combination of rapid customer adoption, grassroots support for solar, improved financing terms, and public market successes displayed clear gains for solar in the eyes of both the general population and the investment community," she said.

While the future does look bright for the U.S. solar industry, it has an incredibly long way to go before it can supply adequate amounts of power to the country's population, and become a vital part of a mixed bag of energy sources that could ultimately replace fossil fuels. Germany, considered the world's leader in the solar revolution, now is able to produce half of its overall energy needs from the sun.

The United States is still stuck below one percent, to put things in perspective.

Yes, the U.S. has a steep hill to climb, but the prospects for solar energy are better than ever. With tariffs helping giving American manufacturers an advantage, the opportunity for job growth and increased investment has never been better.

Solar Power Tower

Solar Power Tower

Cosmological augment - Take in work. In solar power stations, mirrors are hand-me-down to gathering place sunlight and convert it within thermal energy). This process enables temperatures of aloof than 1000 degrees Celsius to be achieved, which can be hand-me-down to construct electricity, in the course of other effects.

Cosmological power towers construct electric power from sunlight by focusing sound solar radiation on a augment mounted boil exchanger (mast). The system uses hundreds to thousands of sun-tracking mirrors called heliostats to weigh up the item sunlight onto the mast. These leaves are peak completely for utility-scale applications in the 30 to 400 MWe range. In a molten-salt solar power augment, liquid saline at 290oC (554oF) is pumped from a restorative stow container before the mast everywhere it is blazing to 565oC (1,049oF) and then on to a heat container for stow.Just the once power is compulsory from the work, hot saline is pumped to a haze generating system that produces superheated haze for a standard Rankinecycle turbine/generator system. From the haze generator, the saline is returned to the restorative container everywhere it is stored and in due course reheated in the mast. "Figure 1" is a chart build of the pin flight paths in a molten-salt solar power work.Determining the optimum stow prominence to assembly point power-dispatch provisions is an gray role of the system thinking process. Maintain tanks can be meant next to beautiful measurements to power a turbine at exhaustive output for up to 13 hours.Top

Cosmological Ascend Form


Figure 1. Molten-salt power augment system chart (Cosmological Two, baseline precedent).

The heliostat stance that surrounds the augment is laid out to optimize the almanac play of the work. The stance and the mast are as well sized depending on the needs of the kindness. In a typical installation, solar energy gathering occurs at a velocity that exceeds the record unavoidable to transfer haze to the turbine.So, the thermal stow system can be charged at the vastly day of the week that the work is producing power at exhaustive measurements. The ratio of the thermal power provided by the miser system (the heliostat stance and mast) to the penetrating thermal power unavoidable by the turbine generator is called the solar complex.Before a solar complex of gruffly 2.7, a molten-salt power augment sited in the California Mojave put off can be meant for an almanac measurements selflessness of approximately 65%. (Based on simulations at Sandia Assert Laboratories next to the SOLERGY laptop order.) So, a power augment possibly will potentially act for 65% of the time sans the need for a back-up fuel source. Worsening energy stow, solar technologies are detail to almanac measurements factors nearby 25%.The dispatchability of electricity from a molten-salt power augment is illustrated in Figure 2, which shows the loaddispatching energy for a typical day in Southern California. The computation shows solar fertility, energy stored in the hot container, and electric power output as functions of day of the week of day. In this example, the solar work begins collecting thermal energy before long at the back of dawn and food it in the hot container, accumulating energy in the container just about the day. In revisit to a peak-load press on the disposable, the turbine is brought on cottage at 1:00 PM and continues to construct power until 11 PM.

Figure 2. Dispatchability of molten-salt power towers

While of the stow, power output from the turbine generator mortar accurate before fluctuations in solar fertility and until all of the energy stored in the hot container is minimal. Energy stow and dispatchability are insufferably gray for the success of solar power augment technology, and molten saline is rumored to be the key to value potent energy stow.Take in towers obligation be large to be penny-wise. Take in augment leaves are not modular and can not be built in the minor sizes of dish/Stirling or trough-electric leaves and be economically aggressive, but they do use a standard power block and can plainly declare power in the same way as stow is untaken.In the Joined States, the Southwest is chosen for power towers such as of its considerable slender levels of insolation and to a certain extent low broken up assignment. Similar locations in northern Africa, Mexico, South America, the Center East, and India are as well harmonious for power towers.

Thermal-energy stow in the power augment allows electricity to be dispatched to the disposable in the same way as press for power is the best, by this means on the increase the economic consequence of the electricity. By a long way have the benefit of hydro leaves, power towers next to saline stow are designed to be a dispatchable amazing than an periodic renewable energy power work.For example, Southern California Edison pied-?-terre gives a power work a measurements punish if it is able to assembly point their dispatchability requirement: an 80% measurements selflessness from the middle of the day to 6 PM, Monday before Friday, from June before September.Detailed studies handle indicated that a solar-only work next to 4 hours of thermal stow can assembly point this dispatchability ought and by this means do well for a exhaustive measurements punish.Even if the a lot deregulated open market advantage may grasp this consequence differently, energy delivered into penetrating periods will certainly be aloof prized.Well making the power dispatchable, thermal stow as well gives the power-plant draftswoman autonomy to flower power leaves next to a great range of measurements factors to assembly point the needs of the kindness disposable. By unreliable the prominence of the solar stance, solar mast, and prominence of the thermal stow, leaves can be meant next to almanac measurements factors ranging together with 20 and 65% (see Figure 6).Commercial studies handle on show that levelized energy assignment are cheap by appendage aloof stow up to a running of approximately 13 hours (~65% measurements selflessness). Even if it is ingenuous that stow increases the value of the work, it is as well ingenuous that leaves next to higher measurements factors handle outperform helpful utilization of the turbine, and other make equal of work fixtures.Equally saline stow is reduced, reductions in LEC due to enlarged utilization of the turbine aloof than compensates for the enlarged value due to the addition of stow.

Indonesia Plans Levy On Crude Palm Exports Instead Of Tax Threshold Cut

Indonesia Plans Levy On Crude Palm Exports Instead Of Tax Threshold Cut
Indonesia will impose a levy of US$50 (RM186) a tonne on exports of crude palm oil when prices fall below a threshold triggering a monthly tax on shipments overseas, the chief economics minister said.

When prices of crude palm oil fall below the threshold of US$750 a tonne on average, the world's top producer of the tropical oil cuts the monthly tax on its CPO exports to zero.

Benchmark Malaysian palm oil futures have fallen more than a fifth over the last year, and ended yesterday at RM2,160 per tonne.

Southeast Asia's biggest economy set its crude palm oil export tax for March at zero, unchanged since October last year.

Indonesian officials are preparing new rules for a charge of US$50 on every tonne of CPO shipped at the zero export tax rate, Sofyan Djalil said, with the funds going to help pay for biodiesel subsidies announced in recent weeks.

"At any (CPO) price we will take US$50 a tonne," he said, making clear that when the CPO export tax kicked in, the government would allocate US$50 a tonne to its biodiesel fund from the revenue earned.

The measure will go to Indonesian President Joko Widodo for approval on his March 30 return from overseas trips.

Indonesia ramped up biodiesel subsidies last month, in a bid to protect its biofuels industry against lower prices of crude and cut costly imports of diesel.

But a subsequent decision to boost the minimum bio content in diesel fuel to 15% from 10% increased the amount of funds needed to pay the subsidies for the higher volumes of biodiesel.

To secure processing supplies, Djalil said the government may also require CPO producers to allocate 15% of total output for domestic use, but gave no further details.

A major industry group this week said the government was looking to lower the threshold for the monthly export tax, to between US$500 and US$600 a tonne.

The CPO export tax, aimed to help processing industries and secure domestic supplies, rises to a maximum of 22.5%, depending on how far above US$750 average prices climb.

Before the recent changes, Indonesia's CPO production was seen rising 7% to 31.5 million tonnes, with exports falling 500,000 tonnes to 19.5 million, industry estimates show.

Major palm oil firms operating in Indonesia include PT Sinar Mas Agro Resources and Technology, Malaysia's Sime Darby and Singapore-based Wilmar International Ltd. – Reuters, March 21, 2015.]]>
