The amount of solar panels it would take to power the Earth is at least 51.428 billion solar panels and it would take around 74.16 million acres of land to power the planet with solar panels.

Solar panels only last 25 years because they lose their efficiency from exposure to the sunlight, humidity, temperature fluctuations and mechanical stress.

Most solar panels have a yearly degradation rate of around 0.5 percent.

Tesla Solar panels are rated to last up to 25 years just like most other solar panels will last around 25 years.

The states you will find the most usage of solar energy in the US are Virginia, New York, New Jersey, Arizona, North Carolina, Nevada, Florida, Texas and California.

The price of a solar panel ranges in cost from $100.00 to $200.00 and as high as $400.00 depending on the wattage of the solar panel.

100 watt solar panels can be bought for around $100.00 and sometimes as low as $50.00

To reset your overload or overloaded inverter disconnect the inverter from the battery and wait 10 to 30 minutes or until it cools down.

Then hook the inverter back up to the battery and turn it on and it should work again.

Some inverters may also have a reset button that you need to press to reset the inverter.

To check if solar is working you can look at the solar charge controller or use a voltmeter to check for incoming voltage from the solar panels.

In some cases you should see 14 to 18 volts or higher coming into the solar panels depending on the voltage of your solar panels.

If your solar panels are not generating electricity it could be that you have tripped a circuit breaker or blown a fuse.

Or a wire could have come loose from the solar panel or the solar panel is bad or not getting enough sunlight.

In rare cases the solar panel may be bad but in most cases it's something else.

The solar charge controller could also be faulty or you have a loose or corroded wire that is connected to the solar charge controller.

If your solar battery is not getting fully charged it could be that there's not enough sunlight or you have a faulty solar charge controller, faulty solar battery or even bad wiring.

If your solar charge controller is not showing amps it could be faulty wiring, loose wiring or an issue or fault with the solar panels or input voltage.

The battery could also be the culprit or even the solar charge controller could be bad.

The amps will drop low if the battery is full or nearly full.

A solar charge controller should be as close to the battery as possible and in the same room or enclosure.

You should install your solar charge controller at least 3 feet or less to the battery or battery bank so that it can charge the battery better.

A solar charge controller does not have a fuse so it's important to install a fuse between the charge controller and the solar panel.

This also avoids any overheating of any wires and prevents appliances or electronics from catching fire or damaged in the event of a short circuit.

A solar charge controller will stop the electricity flow from the solar panel into the battery when the battery is fully charged.

Solar power systems will most often incorporate inverters and charge controllers to ensure trickle charging.

Batteries that are best for solar panels are the Lithium Solar Batteries.

While you can use a regular RV amp hour battery for solar the Lithium Solar batteries are best for solar panel use.

Batteries used in home energy storage typically are made with one of three chemical compositions: lead acid, lithium ion, and saltwater.

In most cases, lithium ion batteries are the best option for a solar panel system, though other battery types can be more affordable.

A solar panel lasts on average of 20 to 25 years.

However in some cases solar panels can last as long as 30 years but as the solar panels age they tend to lose the ability to charge and produce power as good as they would if new.

On average you should replace solar panels after 25 years or when they begin to charge less.

Reflected light will charge a solar panel.

You can place mirrors around your property to reflect sunlight towards your solar panels to help them charge better.

However if you can place the solar panels in the direct sunlight it will be even better.

Solar panels do charge in the shade as long as there's some daylight or some sunlight.

Although solar panels work best in direct sunlight the solar panels can and still do work some in shade or on cloudy days.

It's best however to place your solar panels in direct sunlight for the best results.

Solar panels do need cleaning to keep them from getting too dirty and blocking the sunlight.

It's best to clean the solar panels at least every few months or so unless they get dirty sooner.

Also if the solar panels get snow on them the snow should be removed or the snow will block the sunlight from reaching the solar panels and they won't charge.

Solar panels work in the rain and on cloudy days but the charging of the batteries with the solar panels on rainy days and cloudy days will be less.

You'll still have some charging and power output from the solar panels on rainy days and cloudy days but it won't be as good as it would be on sunny days.

Solar does work on rainy days but on rainy days the batteries with solar panels won't charge as fast or produce as much power.

However even on cloudy and rainy days the solar and solar panels will still work and produce some charge into the batteries.

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.
