PROJEKT 3,8 MW HCOIE

HRVATSKI CENTAR OBNOVLJIVIH IZVORA ENERGIJE

PROJEKT 3,8 MW
Zadarska županija potvrdila je kako je ovo projekt od posebnog interesa, a Ministarsto je izdalo svu potrebnu dokumentaciju.

Elektranu snage 3,8 MW gradit će tvrtka Jadran lux. Vrijednost projekta procjenjena ja otprilike 15 milijuna eura.

U Hrvatskoj zasad postoji tek pet malih fotonaponskih elektrana čija je snaga 62 kW. Kako se ovo područje energetike zadnjih godina bez prestanka razvija, i Hrvati su, izgleda, svatili koliko je važno. Tome je doprinijelo i uvođenje državnih poticaja. Svim investitorima država jamči 12-godišnji otkup proizvedene struje po dosta višim cijenama od uobičajenih. Hrvatska do 2020. treba proizvoditi 20 posto iz obnovljivih izvora energije. Nacionalna energetska strategija predviđa da će dotad ukupna snaga proizvodnje iz obnovljivih izvora biti 1545 MW.

Ministarstvo je dosad odobrilo 87 od 220 prijavljenih projekata iskorištavanja sunčeve energije. Među 87 odobrenih projekata nalaze se i četiri projekta gradnje solarnih elektrana ukupne snage 170 MW.Više informacija na http://solarserdar.blogspot.com.

Igor Raguzin iz Ministarstva gospodarstva kaže:

- Tome će, uz zagarantirane subvencionirane otkupne cijene električne energije i stalni razboj sve efikasnijih tehnologija koje povećavaju isplativost takvih ulaganja, pridonijeti i poticanje investitora iz državnog proračuna, iz Fonda za zaštitu okoliša i energetsku efikasnost, regionalnih agencija i drugih izvora.

Očekuje se da će se ove godine u Hrvatskoj prodati i dvostruko više fotonaponskih sustava nego što je to bio slučaj dosada.

Među europskim zemljama Njemačka je apsolutni rekorder u uporabi fotonaponskih sustava, a u stopu je slijedi i Češka.

Prva velika elektrana na sunčevu energiju u Hrvatskoj mogla bi, kako doznajemo od Darka Horvata, ravnatelja Uprave za energetiku u Ministarstvu gospodarstva, rada i poduzetništva, početi raditi možda već ove godine kod Povljane na južnom dijelu otoka Paga.

Prema njegovim riječima, to je najperspektivniji takav projekt gradnje velike solarne elektrane, jer je ta lokacija kod Povljane već ugrađena u prostorne planove, a Zadarska županija im je potvrdila da je to projekt od njihova posebnog interesa. Ministarstvo je investitorima već izdalo svu potrebnu dokumentaciju potrebnu za ishođenje građevinske dozvole. Osim toga, u tam projektu dobro surađuju sva nadležna ministarstva i lokalne zajednice. Riječ je o elektrani snage 3,8 megavata koju planira graditi tvrtka Jadran lux. Kako stručnjaci ulaganja u takve objekte procjenjuju na tri do četiri milijuna eura po megavatu, očekuje se da će u njenu gradnju trebati investirati između 11 i nešto više od 15 milijuna eura. Zasad je, inače, u Hrvatskoj provedeno samo manjih pet fotonaponskih projekata ukupne snage 62 kilovata, ali u svijetu se ta grana energetike snažno razvija zadnjih godina. U tome prednjači Njemačka, ali se jako puno investira i u Češkoj gdje već radi 12.000 fotonaponskih sustava, a ove će godine, prema njihovim planovima, proraditi još 5000. »Takav ubrzan razvoj investicija u korištenje sunčeve energije omogućilo je uvođenje relativno visoke zajamčene otkupne cijene za struju proizvedenu iz tih sustava, a postupno je padala i cijena njihove gradnje«, objašnjava Tomaš Kuhta iz češkog veleposlanstva u Hrvatskoj.Više informacija na http://solarserdar.blogspot.com.

To je investitorima omogućavalo veliku dobit i povrat ulaganja već za tri do četiri godine. No, češki elektroenergetski sustav zbog tehničkih razloga nije mogao podnijeti toliko solarnih elektrana, pa su morali zaustaviti njihovo tako brzo širenje. »Zato je Češka uvela porez na dobit kod takvih projekata od 20 posto, što je povrat ulaganja produljilo na 11 do 12 godina i smanjilo atraktivnost takvih investicija«, kaže Kuhta. I u Hrvatskoj je interes za ulaganje u obnovljive izvore energije znatno porastao nakon uvođenja državnih poticaja, koji svim investitorima prvih 12 godina omogućavaju zajamčeni otkup sve proizvedene struje po dosta višim cijenama od redovnih. Novac za to skuplja se iz naknade od pola lipe po potrošenom kilovatsatu, koju uz račune za struju plaćaju svi potrošači. Hrvatska, naime, želi do 2020. godine 20 posto energije u bruto neposrednoj potrošnji proizvoditi iz obnovljivih izvora energije, a po nacionalnoj energetskoj strategiji do tada bi trebali imati obnovljive izvore ukupne snage 1545 megavata. Ministarstvu gospodarstva je dosad prijavljeno 220 projekata za korištenje sunčeve energije, od čega su dosad odobrili 87.

Među njima su i četiri projekta gradnje solarnih elektrana ukupne snage 170 megavata, kažu u Ministarstvu. Veće korištenje solarne energije, kao i ostalih obnovljivih izvora, za što Hrvatska po tvrdnjama stručnjaka ima velike potencijale, olakšat će najavljeno pojednostavljivanje dosta kompliciranih administrativnih procedura za dobivanje potrebnih suglasnosti i dozvola, značajno povećanje kvota, a do kraja godine trebao bi biti donesen i zakon o obnovljivim izvorima energije. »Tome će, uza zajamčene subvencionirane otkupne cijene struje i stalni razvoj sve efikasnijih tehnologija koje povećavaju isplativost takvih ulaganja, pridonjeti i poticanje investitora iz državnog proračuna, iz Fonda za zaštitu okoliša i energetsku učinkovitost, regionalnih agencija i drugih izvora«, napominje Igor Raguzin iz Ministarstva gospodarstva. Zato nije ni čudo da se očekuje snažan rast investicija u obnovljive izvore energije u Hrvatskoj, a Horvat očekuje da će već ove godine proraditi možda i dvostruko više takvih proizvodnih kapaciteta nego ukupno do sada.

Koliko je velik interes za ulaganje u fotonaponske sustave, kao i ostale obnovljive izvore energije, pokazao je i golem interes za seminar »Mogućnosti primjene obnovljivih izvora energije - fotonaponski sustavi«, koji je u Ministarstvu gospodarstva, rada i poduzetništva organizirala tvrtka Energetika marketing, izdavač specijaliziranog časopisa za energetiku - Ege. Naime, na seminaru se okupilo više stotina stručnjaka te sadašnjih i zainteresiranih investitora iz Hrvatske, ali i inozemstva. O tome su govorili vodeći znanstvenici i stručnjaci s nekoliko visokoškolskih ustanova i instituta, nadležnih državnih tijela i stručnih udruga, a predstavljeni su i najuspješniji primjeri iz prakse, kao i koristi od takvih ulaganja. Tako je Ljubomir Majdanžić, predsjednik Hrvatske stručne udruge za sunčevu energiju, istaknuo da bi samo veće korištenje sunčeve energije za proizvodnju električne i toplinske energije moglo u idućih sedam-osam godina otvoriti oko 6000 radnih mjesta, dok je Igor Raguzin iz Ministarstva kazao da bi prema okvirnim procjenama obnovljivi izvori energije do 2020. u cijelom gospodarstvu mogli otvoriti čak 60.000 do 80.000 radnih mjesta.Više informacija na http://solarserdar.blogspot.com.

Solar Energy Technology by CCRES



Many cars slow to a crawl as they leave and enter Morningstar Marketplace via Lincoln Highway West in Thomasville. The drivers snap their heads to the side to look in awe at what used to be a plain, grassy field.
The field is becoming a solar farm that will provide all the power needed and then some to operate the combination flea, antique and farmers' market. Rows of metal racks line the field, a few of them supporting gleaming solar panels. Construction equipment sits amid overturned earth, signs of a project ongoing.More info at http://solarserdar.blogspot.com.





As the most oil dependent state, Hawaii is adding wind farms and solar arrays to its skyline.More info at http://solarserdar.blogspot.com.





DTE Energy has installed a solar panel farm at Ford's Michigan Assembly Plant. When the sun's out, enough energy can be stored to power 100 Michigan homes, but the panels aren't powering houses in the area. They're helping build more efficient cars more efficiently.More info at http://solarserdar.blogspot.com.

While the sun generates enough energy to meet the world's energy needs many times over, the challenge is to capture that power for our use at reasonable cost. Today's solar energy technology converts the sun's light to electricity and absorbs its heat for heating and cooling systems. Large solar plants absorb the sun's heat to power steam turbines that produce electricity.

Solar Electric (Photovoltaic)
Solar technology that directly converts sunlight into electricity is called solar photovoltaic (PV) technology. PV produces direct current electricity, which can be used on-site, stored or converted to alternating current for long-distance transmission.

Solar Heating and Cooling
Solar heating and cooling technologies capture the sun's heat to provide energy for water heating, pool heating, space heating and cooling, and industrial process pre-heating. The technology can be used for residential, commercial, and industrial use.

Concentrating Solar Power
Using reflective materials, like mirrored troughs, utility-scale systems concentrate the sun's heat to warm a synthetic liquid to temperatures over 500 degrees Farenheit. This fluid heats water that in turn powers steam turbines to produce electricty.

Passive Solar
Architects and builders use special siting, design and materials to absorb the sun's heat that later is released to warm during cooler evening and nights. Passive solar also refers to directing sunlight to brighten interior spaces and positioning shading devices to protect from excessive heat.

Solar Ovens
Solar ovens are a low-tech, low-cost option to heating and cooking food. Similar to a crockpot, solar ovens are essentially well insulated portable boxes that capture and hold the sun's heat.

Emerging Technology
Research and development by companies and research labs are continually discovering new techniques and materials that improve efficiencies and cut the cost of capturing solar energy.

Why should you go solar - SOLAR SERDAR

Why should you go solar
SOLAR SERDAR



Electricity is the most efficient power source available to us every day and getting electricity from the Sun is only natural.
A simple 3 kW solar system will avoid the release of 3 tons of carbon per year, this is equal to planting an entire acre of trees. No greenhouse gases or pollution. No burning coal or oil or natural gas or propane.
If you have a south facing roof or land that is free from shade from 9 to 3 then you have a desirable solar location. The more direct sun the better, however about 4 hours of direct sun is adequate year round.
Buying a solar system now with heavy incentives will give you electricity for more than 25 years, most panels last longer. Solar panels power all the satellites in outer space and they have been working for more than 50 years. All that free electricity can be yours.More info at http://solarserdar.wordpress.com
During the daylight hours, energy created is used in your home and excess energy is sold back to the power company through current electrical wiring. Net Metering allows you to sell the unused power to the utility company. Older dial meters will actually spin backwards.
Solar is easy to install without any heavy machinery and solar energy requires no moving parts and no maintenance.


Estimate your solar potential by drawing a system on your roof!

Most solar panels are warranted for 25 years and so your investment is safe and will deliver power for years to come that is pollution free. If one panel should fail it can easily be replaced.
The federal and state incentives are the highest they have been in years. Some states cover up to 80 % of the cost of your solar system.
The solar system can increase the value of your home as well. What would you buy, a home that makes its own electricity or one that has a huge electrical bill every month? And solar systems have no sales tax, and do not add to your homes property tax. More info at http://solarserdar.blogspot.com
The US has great solar energy potential, looking at the map below shows just how much more sun the US gets compared to Germany which is the largest solar market in the world. Imagine the power we could generate if we all had solar.
Solar panels are strong, passing hail tests, and are regularly installed in Arctic and Antarctic conditions.
You can add backup power to your home for days when power outages happen by adding a bank of batteries which will be charged by your solar system.
Solar panels will reduce wear and tear on your current roof, keeping it shaded and preventing natural wear down. Your home will be cooler in the summer due to the natural shading of the solar panels. Most panels are installed on a rack with room for air to circulate underneath them. Thin film panels can stick to your roof but generally produce less energy per square feet than regular solar panels. There are other options as well, such as clay tiled panels, panels which are designed like roof tiles and we can advise you as to the cost of all of your options and various styles.
To estimate your solar cost, multiply your average daily electrical demand in kilowatt-hours by 0.25. The result is the approximate size of solar array, in kilowatts, needed to meet your electrical demand. Solar systems cost about $7 per kilowatt installed. There are also permits that need to be obtained and any associations which try to restrict solar power and we can handle both types of situations. A 10 x 10 area fits 6 panels and makes 1200 watts of power with a installed cost of $8000.

PHOTOVOLTAIC POWER PLANTS by SOLAR SERDAR

RENEWABLE ENERGY CENTER SOLAR SERDAR ( CRECSS )



PHOTOVOLTAIC POWER PLANTS IN CROATIA


In Republic of Croatia exists legislative frame for investments in power plants on renewable sources of energy according to Cratian governments by law for getting a status of privileged electricity producer and tariff system for electricity production from renewable sources of energy and cogeneration.
The photovoltaic systems are classified depending privileged energy prices in three categories:

1) 10 kW and less
2) 10,1 to 30 kW
3) over 30 kW

In reality that means PV s instalation up to 30 kW on family houses, warehouses and other factories, and over 30 kW installation on the ground (on grid).

Comparison shows following economic investment criteria:

a) SHARE OF INVESTMENT PVs ON THE ROOFS

85% facilities and installation (90% modules, 10% converters)
15% installation
Investment per 1 kW+vat=4,50 EURO app.

b) SHARE OF INVESTMENT PVs FOR BIG SOLAR POWER PLANTS

60% facilities and installation (80% modules, 10% converters, 10% installation)
10% project preparing, projects and studies
15% transformer station and connection
10% carriers construction and infrastructure
5% land,buying or renting with license building
Investment per 1 kW+vat=4 EURO app.

The small PVs on the roofs are the most effective in the Croatian regions with insolation under 1200kWp/h (northern parts of Croatia).On the coast and particulary hinterland of Dalmatia and the islands all kinds of PVs are effective because of the insolation much over 1200kWp/h including bigger photovoltaic systems.Particulary interesting are the special care areas because of the lower interest rates ( 4% Croatian Bank for Reconstruction and Development ), and later smaller taxes.More information on
http://solarserdar.blogspot.com/
and
http://solarserdar.wordpress.com/

Low costs of servicing and line connection with the investor and facility supplier are a guarantee of safety and reliablity for the business.
The recent growth of interest to invest in new power plants in Croatia resulted from implementation of laws and regulations that stimulate electricity production from renewable energy sources ( RES ).
Most of these plants tend to connect to the distribution network.

Distribution system operator HEP - ODS ltd.( DSO ) in cooperation with other entities;
HEP - TRANSMISSION SYSTEM OPERATOR ltd, Ministry of Economy, Labour and Enterpreneurship, The Croatian Energy Market Operator continues working on the adjustments and simplifying necessary procedures for connecting power plant to DSO network, as well as on defining the necessary technical requirements on connection of production unit to the power distribution network.

This document gives a procedure for a potential electric energy producer to go with DSO starting the first contact and finishing with a final connecting to the DSOs network. The document gives the actual experiance and current status of inplementation of given procedure; connecting the power plants to power distribution network.
