Roof Overhead Solar Panels – A Great Way To Generate Free ElectricityRoof Overhead Solar Panels – A Great Way To Generate Free Electricity

Despite the global economic recession, rooftop solar energy is enjoying popularity among homeowners. It is now considered one of the cheapest options for alternative energy sources. However, many people are confused about how much does a rooftop solar cost. The cost of installing rooftop solar panels depends on the kind of equipment you choose, as well as the complexity of the system you intend to install. To get the best deal, you need to follow these tips. Here are some factors that will affect the rooftop solar cost:


The size of the solar array will determine the rooftop solar panels price. The bigger the size, the higher the price per kilowatt-hour. Large rooftop installations with a capacity of 100 kilowatts or more will attract more premium prices from the buyers. But if you don’t want to invest in large photovoltaic arrays, then smaller sized residential PV cells can be used for your home needs.


Roofing materials and shapes will influence the cost of your rooftop solar panels too. The most expensive and most popular choice for residential rooftop installations is crystalline silicon modules. This particular kind of material is inexpensive, durable, lightweight, and flexible. But it is also one of the most expensive and the most difficult to install. If you have budget constraints, you may opt for cheaper materials like copper or indium tin oxide, which are also good options but are less popular because they are not as durable as crystalline silicon.

Many homeowners want a completely free roof-top photovoltaic system. However, installing a free-roof system using household materials will cost a lot more than what you have expected. A free-roof system will be more effective at generating energy but it will also be a burden on your wallet. The roof has to be installed by a professional and if there are flaws, then the entire photovoltaic system will have to be replaced. So you should think about how much you can invest in a proper photovoltaic system for your home before making a purchase decision.

There are different types of materials being used in the manufacture of these solar panels. They include poly-crystalline panels, polycrystalline modules, single-crystal panels, n-type (n-type silicon) monocrystalline panels, wafer thin-film modules, solid semiconductors, etc. While all these types are being manufactured, various manufacturing methods are being used. These different types of manufacturing methodologies will determine the final cost of your rooftop solar panels.


The manufacturing process is being determined by the amount of energy needed to generate electricity. If you want to save money, then you should go for low-cost modules. This type of installation is suitable for families who don’t want to spend a lot of money on these panels. But you should choose high-quality modules for more power generation benefits. Moreover, if you want to install the photovoltaic system on a large surface, then you may consider getting the complete power generation benefits.

To get the highest power generation benefits from your rooftop solar panels, you should choose the right size of the unit. For instance, if you are looking for around 30% extra electricity efficiency, then it is advisable to get the unit with a size larger than that of the roof space. A properly installed unit will allow extra electricity generation benefits. Moreover, the number of solar cells you have for this purpose should be increased. It is better to install more cells if you want to get maximum electricity efficiency.

The PV cells can absorb extra moisture and heat from the air. As a result, your energy efficiency may decrease as water or air is always being passed through these cells. Hence, it is advised not to place them near outlets or open windows. You should also reduce the chances of the UV rays entering the system. A qualified and experienced solar specialist can guide you to choose the right and best rooftop solar system for your house. So, now you can easily reduce your energy bills and generate free electricity within just a few months!

Optimizing a Hybrid Solar SystemOptimizing a Hybrid Solar System

A hybrid solar system is simply a hybrid combination of an energy-storage-ready device and a photovoltaic system that deliver consistent, reliable energy output during all times of the day. The hybrid solar system can store energy from the sun during the day for future use in one or more solar batteries but can also pull power from the electricity grid during low energy use times such as hot, summer months. The hybrid solar energy solutions are steadily gaining popularity as a reliable alternative to standard photovoltaic solar panels.

Photovoltaic Systems

Photovoltaic systems have been available for decades but have always required modifications to your home’s layout to accommodate the electrical components. While many homes already have set-up photovoltaic panels, many homeowners do not realize that some states severely limit the total amount of electrical capacity that a residential electrical system can support. The average utility meter footprint in most areas of the country will typically only support a maximum of about 15% of the peak capacity of a typical household’s electrical consumption at any given time. This mandated capacity restriction results in a majority of homeowners being unable to properly use solar panels in conjunction with their existing electrical plans.

The result of this constraint is that most hybrid residential electric generating systems will only be able to properly generate power at peak hours using only the electric energy stored in the batteries. Since conventional photovoltaic panels only convert energy from the rays of the sun to usable electricity, a hybrid PV panel system cannot exceed the maximum demand electrical capacity of the household. The only way to overcome this limitation is by combining multiple photovoltaic panels with an efficient energy storage system. The combined PV / DC electrical system will then be capable of properly converting the thermal light from the sun into usable electricity during peak hours.

Energy Storage

There are two main types of energy storage systems found in hybrid residential solar hybrid systems – active and passive designs. Active systems utilize the batteries for both the hot water and electrical loads. Passive systems employ clever load shifting techniques to allow energy consumption to switch between the batteries and the auxiliary electric components such as air conditioners and central air conditioning units during low-demand times. This allows the systems to operate at maximum capacity even when it is not necessary to use the auxiliary components of the household.

Several factors impact the effectiveness of load shifting concerning hybrid solar PV systems. The size of the panels and battery used in the hybrid solar system plays a major role in the amount of energy that is produced. The larger the required batteries the greater the need for expensive grid assistance. The length of time that the system is run on “maintenance free” parts also impacts the efficiency of the hybrid system. The longer the system is run on its maintenance-free parts the more the energy production from the panels will drop.

Installation Tips

It is important to take care when connecting the panels to the batteries. There are several ways that this can be done including the use of T-backs or C-backs. Both these types of connections are effective but have their disadvantages. The T-back connection is most effective when the PV array is placed at the height of the roof. When the system is placed at an improper height the energy usage from the panels will increase.

Another important factor to consider when optimizing hybrid solar systems is the set up of the batteries. Most hybrid vehicles have standard batteries that can handle maximum demand from the batteries. Many hybrid vehicles have special hybrid batteries that are capable of handling the maximum demand from the batteries. If these batteries are over-discharged below their optimal performance of the hybrid vehicle’s performance will suffer. The vehicle will become harder to drive causing costly damage.

The optimal location for most hybrid solar system designs is on the northern side of the United States. This allows the PV cells to receive the full amount of sunlight necessary to convert the DC produced to AC. Some of the best locations include Texas and Arizona. The materials needed to manufacture these cells are lightweight and flexible making them easy to transport to the required locations. The size of the battery can vary between four hours to six hours. The size of the photovoltaic array will depend on the amount of sunlight needed to generate the power needed for the hybrid vehicle to function.

Best Marine Solar Panels – Saving Money and EnergyBest Marine Solar Panels – Saving Money and Energy

The popularity of marine solar panels have soared as marine solar technology has progressed, and this is good news for consumers. Now, more people are taking advantage of the benefits and affordable costs of marine solar panel technology. There are now more options in terms of size and function than ever before. If you are in the market for solar energy panels, then you will want to consider a few important features before you purchase any marine solar panels. Once you understand these factors, you can select the best marine solar panel for your specific needs.


Shading is one of the most significant features to consider when purchasing marine solar panels. The size and number of shaded cells in the panel will determine its efficacy. Generally, the larger the size of the panel, the more effective the shading will be. For example, a two by three-foot panels with two hundred eighty cells would be greater than a one by two-foot panels with fifty cells. Remember that shading efficiency is directly proportional to the size of the panels. If you only want to shade a small area of your boat, then a smaller panel with fewer cells will be more effective.

Another important feature to consider is the thickness of the solar cells. Thin cells are less efficient because they must rely on the air to absorb the sun’s rays. Thinner cells are better for insulating against the cold and hot temperatures that commonly occur in the marine waters. However, if you are shading a much larger area of your boat or another vehicle, then you will probably benefit from a thicker panel. As a general rule, if you expect to shade at least two square feet of water, then you should invest in a marine solar panels type with three inches of cell depth.

Also, another thing to consider when buying marine solar panels is the effect that curved surfaces can have on the conversion efficiency of the cells. Since the cells are installed right above the water’s surface, it would be more difficult to obtain good angles if you plan to use rectangular or circular solar cells. However, curved surfaces can be addressed by using silicone sealant. Using silicone sealant will allow the solar cells to lay flat, thus improving their conversion efficiency. Also, this silicone will provide a smooth and non-abrasive surface which will make installing your marine solar panels much easier.

Cost of Installation

A third consideration is the overall cost of the installation. This is especially important if you already acquired expensive marine electronics or other equipment that may increase the installation cost significantly. Unfortunately, most people don’t factor in the cost of shipping when they choose flexible solar panels. On the other hand, if you want to save money on solar power installation, then there are a couple of ways to do so. You can either save up for a longer installation period, or you can save up on the actual cost of buying the solar cells in the first place.

The best way to save up on buying materials is to choose flexible solar panels. These panels are specially designed to lay flat on any surface – including curved surfaces. As a result, they will provide you with excellent quality performance while maintaining their readability. It’s because of this that flexible solar panels will be able to meet your needs as far as marine solar panels are concerned while offering much better efficiency than rectangular solar cells. This means that you will be able to significantly lower the cost of your marine solar panels, while still maintaining excellent efficiency levels.

Flexible Panels

It’s also important to note that most flexible panels can’t withstand extreme temperatures. But with the introduction of new coatings, most flexible solar panels have been able to withstand temperatures as high as -400 degree Fahrenheit. Furthermore, most flexible solar panels can produce five times more energy than standard cells while providing superior efficiency levels. As a result, it is now easy to find the best marine solar panels while still maintaining excellent power quality at all times.
