 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, ...
