Photovoltaic cells are a major component of all PV solar systems that convert sunlight directly into electricity.Since the discovery of the first silicon photovoltaic cell in 1950, technological developments have improved performance and changed solar capacity.An increasingly viable and popular renewable energy gridPhotovoltaic grid-connected power generation systems account for 75% of the U.S. market share.S.From 31% in 2009 to installation in 2001.
Grid connection means that the solar photovoltaic system is directly connected to the available power grid or utility lines.The connected system includes one or a set of photovoltaic panels that directly convert sunlight into electricity.The size of the system determines its independence from the grid.The grid-connected system requires an inverter to convert DC to AC.The inverter is connected to the main power supply and 1 m indicates the number of kilowatt hours generated.Excess power can be sold back to the grid.
Even if the solar energy fails or is insufficient, the grid-connected photovoltaic system ensures that the family can always get power.The inverter of the system is connected to a battery pack that can store the energy used in the event of a power outage.One advantage of grid-connected systems is that they do not depend on the sun.Off-grid photovoltaic energy is only intermittent, but the grid-connected system ensures that the grid automatically delivers any additional power required.
More than 35 states now have "net metering" legislation, which means that householders can benefit from selling excess energy back to the grid at normal retail prices.The Department of Energy pointed out that because of the high retail electricity bill, this puts people in Hawaii and New York at a great advantage.State and federal incentives include sales tax exemptions for the system itself, property tax exemptions, and individual state income tax credits.
In addition to reducing energy costs, grid-connected solar systems can also add overall value to the property.A federal study by families in California shows that a 3,100 KW-hour system adds an average of $17,000 to the value of families.
Installing a solar system near an existing utility power line means that the cost of photovoltaic power generation is higher than the cost provided by traditional methods.At the cheapest price, solar energy is about 25 cents per kilowatt hour.Generally between two to four times the cost of utility power supply.The initial cost is high, so in practice, installing a grid-connected solar system is like paying electricity bills a few years in advance.
Licensing and legal requirements for installing grid-connected systems can be costly, complex and time consumingconsuming.Although national standards are beginning to be adopted, the legislative procedures of many regional bodies are different, so the best starting point is the local municipal or county construction sector.
