 What is a Solar home? A solar house refers to a solar roof. PV system or ground? A PV system is installed in the house, so that the daily electricity used by the family is generated from solar energy. Solar home systems can be divided into on-grid solar systems, off-grid solar systems and hybrid solar systems. On Grid Solar System On-grid solar systems are currently the most common solar home systems. After installing the PV panel, the system is connected to the grid. Installing an on-grid solar system means that when night falls or when it rains, the solar panels cannot generate electricity, and the house can get power from the grid. When there is excess production in the daily solar energy production, the electricity will be transferred to the grid. According to NEM, your utility company will pay you for this. Hybrid solar system A hybrid solar system adds an "energy storage" function to an on-grid solar system, and stores excess electricity in a battery. When the solar pa...

  How to Build a Solar Home? Solar Panel  1000  are the basis of solar panels. Choose the right number and size of solar panels for your home based on factors such as PV system home energy efficiency, solar energy needs, roof area and more. On the inverter An inverter converts the DC produced by the solar panel into AC that can be used by the home. Inverters are divided into string inverters and micro inverters. String inverters can be connected in series or in parallel form. PV array microinverters are module-level power electronic devices (MLPE) and are installed on a single panel. It can be independently controlled by the MPPT function, which effectively improves the conversion efficiency. Quick closing device Solar roofs present a DC high voltage fire hazard. Fast shutdown is the NEC's electrical safety code for solar panels, meaning it can instantly shut off current in a short amount of time acceptable to the human body, allowing firefighters to safely perform rescue...

  Although socio-economic factors create water problems, they can be countered with better water management. Between 1961 and 2014, the rate of global freshwater withdrawal (whether from ground or underground reservoirs) increased 2.5 times. According to WRI, water demand for crop irrigation has doubled in the last half century and irrigation accounts for about 67 percent of water used. In 2014, industry requires nearly three times as much water as in 1961 and now accounts for 21 percent of total water use. Although domestic water consumption accounts for 10 percent of total water use, it has increased sixfold since 1961. And very little water is used for animal consumption. But crops grown for animal feed consume 12 percent of the world's irrigation system. That's why experts believe that by reducing the growing demand for animal meat, we can reduce the pressure on water resources. Hofstede says that this is the only way to solve the global water problems. "We use a lot ...

Water Scarcity:  According to the Washington DC think tank World Resources Institute (WRI) , Pakistan has nearly 400 areas in the world where people are facing water problems. Developments around the world, increased meat consumption and economic growth have strengthened the world's water reserves, with fears that their depletion will force people to migrate and lead to political instability. will be born From Chile to Mexico, from Africa to the tourist destination of Southern Europe, water issues are getting involved. Aquifers, i.e. 'stressed' water problems are related to the criteria that water is being used from groundwater and other surface reservoirs compared to available resources. About one-third of the world's population, about 2.6 billion people, according to RI, are others in what are being described as 'high water stressed' countries. Of which 1.7 billion people are in 17 countries. A dozen countries in the Middle East are facing the most difficu...

  Learn to live with water scarcity Regions around the world are experiencing drought and water scarcity, even in places that once had abundant rainfall, and this situation will worsen as the planet warms. In 2018, nearly all water taps ran dry in the South African port city of Cape Town. Then it became the second largest city in the world suffering from severe water shortage. This problem still occurs. This year, communities 750 kilometers east of ' Nelson Mandela Bay' will find their reservoirs dry by July. The Cape Town administration has taken strict measures regarding water usage to avoid this 'Day Zero'. The city administration has increased water usage rates and fines and has worked with the agricultural sector to reduce water consumption and maintain soil moisture. Residents of the area will maintain a daily water consumption limit of only 50 liters or 13 gallons. Remember that one load of laundry can use up to 70 liters of water. Ingrid Koetse, a biodiversity, ...

 Early Education of Aisha al-Bauniyya Ayesha and her brothers were given early education in Quran, Hadith, Fiqh and poetry by their father. Aisha's biographer Emil Homeren, a religious teacher, wrote that she had memorized the Qur'an at the age of eight. This biography also emphasizes the role of the Prophet of Islam in Aisha's spirituality and examines the influence of figures such as Ibn al-Arabi, al-Basiri and Ibn al-Farid. Homerin writes that during the Mamluk period (the Mamluk dynasty that ruled Egypt and Syria from 1250 to 1517), Arabic, knowledge and literature flourished, and scholars and students from all over the Muslim world were attracted to Cairo and Damascus. This created opportunities for travel, education and employment. Writer and poet Ayesha al-Bawniyyah also, as a woman, overcame several social and cultural barriers to enter the realm of religious scholarship and literature. According to Homerin's English-language biography, Aisha probably wrote mor...

 Turkey: What will Tayyip Erdogan do after another victory? Erdogan is seen as the front-runner ahead of the May 28 presidential election. The second phase of the presidential election in Turkey will begin on May 28 as no candidate could get the required 50 percent of the votes in the first phase of the election on May 14. The contest between President Recep Tayyip Erdogan and joint opposition candidate Kemal Kilicdaroglu will be the first such contest in the country's political history. Erdogan is widely seen as the front-runner in the contest, having narrowly missed out on the presidency in the first round. With Erdogan's control of most state resources and media outlets down by about five percent, Kılıçdaroğlu faces an uphill battle. Since May 14, he has tried to change the political landscape by changing the tone of his rhetoric, when ultra-nationalist candidate Sinan Ogun won more than five percent of the vote in the first round. Who has more enthusiasm? Despite major eco...

 How to prevent children from playing mobile games at night in China? Chinese company Tencent, famous for online games, is now going to introduce a new facial recognition feature that will prevent children from playing any game between 10 pm and 8 am . The company says that with the help of this technology called 'Midnight Patrol', every trick to avoid the government curfew will be caught. The curfew was introduced by the government in 2019 to set a limit on in-game money transfers by young gamers. Under these restrictions, gamers have to register themselves in the game using their real identity. This information is already available in the national database. But according to reports, to avoid this, children are playing games day and night using the identities of adults instead. Now after these measures, gamers will have to prove they are adults through facial recognition for a long time. Tencent started testing the system in 2018, but the technology will be available in mo...

Cross training: A technique in which exercising one part of the body increases the strength of a weak muscle on the opposite side. In case of any accident, if any part of our arm or leg is injured, it is a common practice to support the injured limb with a special elastic band (sling) to keep the injured limb from moving. However, this practice for a long time sometimes causes the muscles of the affected area to weaken and decrease in volume, and in this case it takes a long time for these muscles to recover. However, medical experts are now researching the effects of 'cross training' for this. According to experts, recent studies show that cross-training can reduce the loss of muscle mass in the unused arm. This technique can increase the strength of the right arm by 20% and increase the strength of the weak arm by 10%.   The technique of cross-training was first discovered 100 years ago, over a but the mechanisms behind it are still not fully understood. Researchers review...
