In general, solar photovoltaic systems sized between 1 to 5 kilowatts are usually sufficient to meet the electricity needs of most homes.
The photovoltaic panels do not have any moving parts and generate electricity quietly, without being harmful to the air.
Eco-friendliness must be considered in any discussion of solar power versus generator. That is, which is kinder to the environment: solar power or generator? The obvious answer again is solar power.
Solar power systems often get an additional financial boost as well: many jurisdictions and utilities across the USA offer attractive financial incentives to drive down the upfront capital costs associated with a solar power system.
You cannot store conventional power but you can store solar power for future use. The sun’s energy comes to rescue even in the times of darkness! Storing it also ensures a 24x7 supply of power, thus saving you from any power outage.
Solar power systems permit you to plan for installation of a basic system and then carry on adding to it as you gain more experience and have less economic constraints.
Another use of solar power is to heat water.
Today you can even buy an air conditioner that is powered by solar cells during sunny days and at night you can run it from the backup batteries, which are recharged the next day.
Many states and local jurisdictions offer rebates, tax credits and other types of incentives to homeowners for installing residential photovoltaic and solar domestic water systems.
Installing a solar home lighting system is done through the use of solar cells that convert solar power into electrical power in your home. The cells are charged with solar energy during the day that can then be used for lighting at night in your home. Another great way to save on your electric bill.
