How to heat water with solar panel?

The use of coal contributes to the formation of poisonous gases and environmental pollution, and that’s why people are looking for an alternative sources of energy. In the face of the challenges of climate changing, we are faced with the need to look for alternative energy sources to reduce environmental pollution. One of them is the use of solar energy in the form of solar panels mounted on the roof. They can be used both for heating domestic water and supporting central heating, or can be used as a photovoltaic source of electric energy. From my post, you will learn how to use solar heat and solar panel to get cheap hot water for the own household.

Solar panels

Solar collectors are in the form of mirrors with very large surfaces or a structure consisting of vacuum glass tubes. Panels are mainly installed on the roofs of houses. They catch the rays of light, thus accumulating the energy needed for conversion into thermal energy.

Such a process of accumulating heat is possible thanks to the absorber placed behind the glass or in a glass tube. It absorbs energy from the sun and is connected to a system of copper pipes. The heating-up solar liquid, propylene glycol solution, flows through them, from which the heat is transferred to the utility water.

Benefits of solar thermal panel

The advantages of solar collectors cannot be overestimated because their installation allows, in a completely ecological manner, to obtain heat necessary to hot tap water and to support central heating. Another advantage of solar panel is that they are working without polluting the environment.

Their third advantage is energy efficiency. Solar thermal panel meet up to 70 percent of the annual demand for thermal energy, which is needed to heat domestic hot water, especially in the months from March to the end of October. In the summer, a properly selected solar panels set will cover up to 100 percent of the demand for domestic hot water.

Another advantage of solar collectors is the convenience of their use and trouble-free operation. Correctly mounted on the roof solar panel, will require maintenance around one time per one-two years. Solar panels are versatile devices that can be installed on the roofs of single-family and multifamily houses, as well. Installation of solar panels will increase the value of your house. Now, when you know more about solar panels, you can decide to use them or not. If you are house owner, it is worth to take positive decision and install solar panels or PV panels.

In What States Are Radar Detectors Legal to Use

A fair amount of people that own cars in the United States have their own radar detectors. Their reason for having one is because they feel the speed limit presently is too low.

Most Americans are not satisfied with a moderate speed while driving. They want to be the fastest driver on the road, as well as get to the places they’re going to in record time.

The radar detector serves as their alarm whenever there are police near by. Once the radar detector alarm sounds, they can ease up on the gas pedal and slow down their speed.

The radar detectors work by picking up a signal from the policeman’s radar gun. Unfortunately they are not effective 100%of the time.

Because of the radar detectors being used by so many motorist, cops have resorted to hiding in alleyways or behind bridges, in an attempt to avoid being detected by the radar detectors.

Motorists on the other hand are being clever themselves, they are aware of these tactics from the police. So to overcome the cops strategy of being deceptive, more enhanced, top-dollar detectors have entered the market.

Although the police are always improving their techniques of catching the radar detector users, they are not able to keep the road radar detector free.

Another form of radar detection are laser jammers. They work by transmitting an invisible light source back to the original police laser gun. The return signal confuses the laser gun and the officer is unable to clock the driver’s speed.

Radar detectors are legal in many cities and states throughout the United States. But, in some of the states that allow radar detectors they have some restrictions.

I have prepared a list below that discusses the states with laws against radar detectors and the states with restrictions.

-Virginia, Georgia currently prohibits the use of radar detectors.

-The District of Columbia does not allow radar detectors. Radar detectors are also not allowed in all commercial vehicles and all vehicles over 18,000 pounds or heavier.

-Alabama, Alaska, Arkansas, Arizona, California, Colorado, Connecticut, Delaware, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Montana, Nebraska, New Hampshire, New Jersey, Maine, New Mexico, Nevada, New York, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin and Wyoming have all banned mounting radars and/or obstructions on the windshield.

-Missouri and North Carolina have no restrictions on window obstructions.

-Radar jammers are not allowed in any state. This is a federal law.

-Alabama prohibits radar detectors on all commercial vehicles.

-New York does not allow radar detectors on commercial vehicles over 18,000 pounds.

-New Jersey and Ohio prohibits radar detectors on all commercial vehicles.

Florida does not allow radar detectors on commercial and personal vehicles over 10,000 pounds.

-The following states permit radar detectors in private vehicles but not in commercial vehicles: Alaska, Montana, Iowa, Arkansas, Maryland, Nevada, Connecticut, Idaho, New Hampshire, Rhode Island, Pennsylvania, Indiana, Kansas, Arizona, Maine, Kentucky, Delaware, West Virginia, Michigan, South Carolina, Louisiana, Missouri, Tennessee, Nebraska, Mississippi, Wisconsin, Vermont, New Mexico, Hawaii, North Carolina, Massachusetts, North Dakota, Oklahoma, Illinois, Oregon, South Dakota, Texas, Utah, West Virginia, and Wyoming,

In Illinois, radar detectors are only regulated in commercial vehicles of over 26,001 pounds.

-On US military bases, radar detectors are legal to have but illegal to use. (??)

-Laser Jammers are illegal to use in California, Illinois, Colorado, Minnesota, Oklahoma, Nebraska, South Carolina, Texas, Utah, Tennessee, -Virginia, and Washington D.C. And since there is no federal law banning them, they can be used in other states.

If you are considering buying a radar detector be sure to know what your state’s law is regarding the use of them. Also do some research on the different types of radar detectors available to suit your needs.

Before you start shopping for a radar detector, make sure you understand what options are available.

Such as:

Corded Radar Detectors

Cordless radar detectors

Remote-Mount Radar Detectors

The Factors:



Smartphone or GPS connectivity


Take your time in selecting the right radar detector. Lighten up on the heavy foot with the gas pedal and be safe.
