Solar Home System

 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 panels are in a state where they cannot produce electricity, the house draws power from the battery. Basically there is no power outage in the house after installing hybrid solar system. Even if the grid stops supplying power, the home battery will provide power.

Off grid solar system

An off-grid solar system is when a home relies entirely on solar energy to generate electricity. This is not common, as it requires a large scale. PV systems to meet daily household electricity demand.

Off-grid solar systems are more likely to be used in small mobile buildings such as boats and RVs.

Why Solar Homes?

Increase in electricity rates

Natural gas is an important source of electricity. Due to the recent international situation, Russia's external natural gas supply has decreased, resulting in a significant increase in natural gas prices in some countries.

National Grid has announced that electricity prices will rise by 60% in the next six months from November 2022, with France's largest power producer saying it will increase electricity prices by 8.6% in the fourth quarter.

Reduced cost of solar energy

With the rapid development of PV industry, the manufacturing cost of solar energy systems has been controlled and reduced. According to an IRENA report, global solar... PV electricity production has declined by 82 percent over the past ten years.

The main reasons are technological innovation and the integrity of upstream and downstream supply chains

Learn to live with Water Scarcity

Image
  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, ...

A Thirst for Economic Growth

  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 ...
