A solar panel needs at least 4 to 5 hours of direct sunlight to provide enough charge to the batteries.

However even on cloudy and raining days the solar panels will still work but just not as good.

Even though the average day is exactly 12 hours, the power you actually get on your panels is equal to about 5 to 6 hours of full sun per day.

Since the typical modern solar panel is about 12% efficient, you will get about 700 watts per square meter of panel.

Solar panels do not drain batteries at night.

Even though the sun is not shining at night and the batteries are not getting a charge the batteries will not be drained unless you leave something plugged into the inverter.

However the inverter and charge controller can drain some power off the battery at night but with a large enough battery bank that should not be much of an issue as the power drawn at night is very little.

Solar panels do work in the morning once the sun comes out.

As long as there's some daylight the solar panels will begin charging so once you get some daylight in the morning the solar panels will charge and work.

However solar panels don't work once the sun goes down as they need daylight and sunlight to produce the electricity.

Solar panels do work with ice on them as ice is clear and lets sunlight pass through.

However the solar panels tend to work much better without ice but if ice is on the solar panels your solar panels should still work and charge the batteries.

However if snow is on the solar panels the snow will block the sunlight and the solar panels will not work so you have to sweep off and remove snow from the solar panels for them to work.

Solar panels do not charge batteries at night.

To work the solar panels need sunlight or at least some daylight for the solar panels to convert the light or sunlight into electricity.

At night the light is gone so the solar panels stop charging but the next day when the daylight or sunlight is out the solar panels begin charging the batteries again.

Solar panels do however work even when it's cloudy out but they don't charge as fast as they do when it's really sunny out.

Solar panels do not work at night as they require sunlight to work.

However when it's cloudy and there's at least some daylight the solar panels will still work.

But once it becomes dark for the night the solar panels stop charging but the power stored in the batteries can still be used but they won't charge until the daylight or sunlight comes out.

Solar panels when installed correctly on your roof do not damage your roof.

Solar panels installed on your roof can usually make your roof last longer as it protects the shingles from the elements.

However if not installed correctly then the solar panels may damage or ruin your roof.

Solar panels can and do sometimes catch fire but it's rare for solar panels to catch fire.

Solar panels may catch fire due to shorting out through the wiring or by a defect in the solar panel.

Although most solar panels are safe when installed correctly and many solar panels operate just fine and safely without any fires.

Solar panels don't always affect your house insurance unless you want to increase your insurance coverage to cover the cost of the replacement of the solar panels and system should you need too in case something happens to them.

Simply installing the solar panels on your house or near your house won't and should not change or affect your house or homeowners insurance.

PV on a meter box means Photovoltaic which means that the meter is connected with solar panels and usually has solar power feeding backwards into the power grid depending on how it's set up.

Sometimes solar panels are set up to where they will feed excess solar energy back through the meter and then the customer of the electric utility gets credited.

PV on a solar charger stands for Photovoltaic.

Photovoltaics is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry.

The photovoltaic effect is commercially utilized for electricity generation and as photosensors.

Another name for a solar panel is photovoltaic cell or solar collector.

A photovoltaic cell (PV cell) is a specialized semiconductor diode that converts visible light into direct current (DC).

Some PV cells can also convert infrared (IR) or ultraviolet (UV) radiation into DC electricity.

Most solar panels last between 20 to 25 years before they need replaced.

Some solar panels may even last as long as 30 years but the average lifespan of a solar panel is 20 to 25 years which is pretty good.

Solar panels are a good investment especially in areas where electric rates are high.

Although you need to purchase the solar panels, batteries and inverters they are a good investment and can save you money on your electric bill.

Also when the power is out such as due to a storm etc you can still have electricity as long as the sun is shining and you have enough charge in your batteries.

To run a house off of solar panels you would need between 20 to 24 solar panels.

However smaller houses with less electricity usage may get by with around 10 to 15 solar panels but it's always good to have more solar panels than needed to provide you with plenty of electricity.

Solar and wind power can power at least 85 percent of Americas energy needs.

However there's not enough solar or wind power available to provide all of America with electricity so we still need some coal, natural gas, nuclear power plants etc to provide some of the electricity that we use.

The amount of solar panels it would take to power the entire united states is at least 7.85 billion solar panels and those solar panels would need to provide at least 350 watts each per hour.

Solar's abundance and potential throughout the United States is staggering: PV panels on just 22,000 square miles of the nation's total land area about the size of Lake Michigan could supply enough electricity to power the entire United States.

The amount of solar panels that would be needed to power the world is at least 51.4 billion 350 W solar panels.

With countries racing to end their reliance on the fossil fuels that cause climate change, it's a boom time for renewable energy.

Now, an international team of researchers has determined that if every available rooftop was equipped with solar panels, they could generate enough electricity to power the world.

Solar panels do work some when the weather is cloudy although the solar panels charge slower when it's cloudy out.

Solar Panels work best when the sun is shining really bright.

In the hot summer sun the solar panels produce the most power.

You can even power window air conditioners with solar panels if you have enough solar power and a big enough inverter and battery bank setup.

Solar Panels do work still when it's cloudy out.

Although when it's cloudy outside and the sun is not shining enough the solar panels may charge the batteries a bit slower than the would if it were sunny out.

Solar Panels work best when it's sunny outside and you get more power and charge from sunny days than you do on cloudy days.

But even when it's cloudy outside your solar panels will work to charge your solar panel batteries and provide you with some power.

Solar Panels will work with either direct or indirect sunlight to generate power.

Solar Panels are most effective when you have direct sunlight but they also are still pretty effective when the light is reflected or partially blocked by clouds.
