How do solar panels store energy?
Solar panels don't store energy. Solar cells convert sunlight in heat or electricity that must be used immediately or stored in batteries so it can be used later.
How safe are solar panel systems?
The electricity generated by solar panels after it has gone through an inverter is the same as utility power. No dangerous materials will leak out of the system because solar panels are made of silicon.
What is the average life expectancy of a solar panel?
Most solar panels are designed for outside use so they can withstand bad weather. Typically a solar panel will run about 20 to 40 years depending on the type.
What is a solar cell?
A solar cell is a small area on a solar module.
What is a solar module
A solar module is made of several solar cells.
What is a solar panel?
A solar panel contains several solar modules set into a rack.
What is a solar panel array?
A solar panel array is made of several solar panel together.
Should solar panels be cleaned when they get dirty?
It isn't necessary to clean solar panels when they get dirty. The dirt will not significantly impact the performance of panel and as soon as it rains the dirt will be washed off.
Do solar panels produce electricity on a cloudy day?
On an average cloudy day there is enough diffuse sunlight to produce electricity. But of course the energy production is higher if the solar panels are placed in bright sunlight.
