Solar panels are comprised of 60–96 solar cells that are joined together. These cells convert sunlight into usable electricity for your home. The amount of electricity produced by the solar panels depends on how much sunlight they receive each day.
The number of panels it recommends is tailored to your needs and is based on the following factors:
One of the best things about solar panels is that they are extremely durable. Odds are, you won't need any solar maintenance at all once they've been installed. You may have to clean your panels if debris starts to collect or if it snows; but other than that, you won't have to do much of anything to keep your solar panels functioning for years to come.
The panels will produce electricity but it will be very limited -- depending on how much light can get through the cloud layers. Homeowners with solar power will still be able to use traditional electricity from their local provider just as they did before the solar equipment was installed.
The amount of electricity produced will vary with the seasons as the angle of the sun changes from summer to winter. In the winter, the sun angle is low in the southern sky so the amount of sunlight reaching the panels is less. In the summer, the sun angle is high so the panels produce more electricity.
As a general solar industry rule of thumb, solar panels last about 25-30 years. However, this doesn't mean that they stop producing electricity after 25 years – it just means that energy production has declined by 80% what manufacturers consider to be a significant amount.
No the Solar panel will degrade 1% every passing year and it will continue even after 25 years.
Space requirements range from 120 to 150 sq. feet per kW of solar PV installed depending whether it’s a rooftop or ground mounted and the tilt angle of the solar PV modules.
