Evaluating Roof-Top Home Solar For Your Home or Business

Is it Physically Possible?

The first thing you need to do before getting pricing, product research, or calling a professional is to determine whether solar is physically possible for your home. There are a number of methods to installing solar on a home but if your house fails the physical requirements, you will not be a candidate for solar. In New York and Long Island, and world-wide, the majority of solar panels are installed on roofs which are either pitched or flat. The primary considerations to be discussed with regard to the physical possibility of going solar for your home is the Directional Orientation of you the roof exposure and its associated architectural characteristiscs.

Solar Panels need to be installed facing South, South East, South West, East, or West. The sun rises in the east and sets in the west so why cant we put panels on the northern exposure of our roof? The reason is because the sun travels along the southern lattitude from east to west. which is why perfect south (180 degrees) is ideal. If your house is facing 180 South, you will recieve the most exposure as the sun travels from East to West. If your system faces perfect West(270 Degreees) or perfect East (90 Degrees), you are still very much a candidate for a successful solar energy system. Your production may be 2-5% less than a house facing perfect South.

How Do I Determine the Orientation of My Home

The simplest way to determine the orientation of your house is to use either a traditional compass or an iPhone/Android compass App. Go to Each side of your home to find the various exposures of the house with a note pad writing down each side of your house and which direction it faces.

An additional way to find the orientation is through google search of your home in either google earth or google search.If you dont have Google Earth installed, please find the link to install it HERE–> Follow the prompts to install the software and then run it. Once on the main screen, Please see a basic step by step guide to evaluating whether your roof or ground area has a viable orientation for solar panels HERE–>Find Your Home on Google Earth

If you find the approach laid out above for finding your home on google earth difficult, there is a more detailed approach HERE–>

If you prefer to use google search to find your home, simply go to Then click on the square-shaped satellite icon which will display satellite imagery rather than traditional road maps. Once in satellite mode, type in your home address and type in your full address and click search or press enter. Use the Zoom (+) icons on the screen to locate your house.

How Do I Determine if the Architecture of My Home is Good For Solar?

If you do have one of the mentioned orientations, (S, SW, SE, E, W), now you need to identify if the roof is ideal for solar with respect to usable space. Since solar panels are rectangular, then the roof must have enough available space to fit these rectangular shapes. Usually dormers and other angular architecture such as corners or domes get in the way. By evaluating your roof or ground mount this way, you will determine the difference between total square footage vs. usable square footage.

Please see an example of a house that has a lot of space on the roof but due to the shapes and architectural obstructions, is not a good physical match for going solar. In not only is there a tree looming over the southern side of the home, but there is also a tremendous amount of angular architecture as well as rounded dome like structures (witch’s hats) getting in the way of placing enough rectangular shaped solar panels on the roof. Even if the customer was willing to trim or cut down the tree, the roof does not allow for a viable opportunity for the customer to go solar.





GOOD ROOF FOR SOLAR 300x177 Solar Power Buyers Guide to Roof Top Home Solar Systems In New York City and The 5 Boroughs, and Long Island  PART 1




Here, you can see what a good candidate for solar looks like on a pitched roof. As indicated by the arrow on the top right corner, the orientation is showing South West which is good for solar. In addition, there are no major architectural difficulties preventing solar panels from being uniformally placed on the roof. Finally, there is a minimal amount of roof obstructions(tree shading, roof vents, fans, and chimney’s). If you have some of these obstructions, it does not necessarily exclude you from going solar. However, as indicated above in the house which was a bad candidate for solar, the obstructions need to be excessive whereby solar is not feasible at all. You can also call ABest Energy Power to assist you in making the determination by calling us at our Toll Free Number at (855) 411-4SUN.

Great Flat Roofs For Solar

These are examples of flat roofs which would all be good candidates for solar since they are facing south with minimal obstructions. There is a big tree in the back of these homes. However, it is on the Northern side and will not create shading issues.







If you have made it to this point and have concuded that you are a candidate for a roof top solar energy system, then you are an official candidate for solar. The next step in the proces will be:

  • The financial aspects of going solar
  • Choosing the Right Equipment
  • Choosing the Right Contractor

We hope the information presented in the first part of this series was helpful. If you would like to speak to an ABest Energy Power representative at this point, please call us at (855) 411-4SUN.

How to choose and buy solar energy-saving lamps

Article by Guoyongqiang

In the design of solar lighting, involving light, solar systems, battery charge and discharge control and many other factors, any one part of the problem will cause product defects. Solar lamps that total consists of five parts: solar panels, charge controller, battery, load and lamp housing.

A solar cell

Solar cells main function is to convert light energy into electrical energy, a phenomenon called the photovoltaic effect. Among the more common solar cell and a more practical silicon, polycrystalline silicon and amorphous silicon solar cells, three. In too sunny, sunshine good eastern and western regions, the use of polycrystalline silicon solar cells as well. For polycrystalline silicon solar cell production process is relatively simple, single-crystal low price, the conversion efficiency has been improving. More in the rainy days, the sun is relatively not very abundant in the southern region, the use of single crystal silicon solar cells as well, due to electrical performance parameters of single crystal silicon solar cells is relatively stable. The amorphous silicon solar cells in the case of weak indoor light is better, because the amorphous silicon solar cells on solar illumination conditions require relatively low.

First of all, any one of the solar lighting products we must first understand the solar cell, solar cell has five electrical performance parameters, namely: short-circuit current, peak current, open circuit voltage, peak voltage, peak power.

The average user is concerned, how do we know it’s five parameters values? Teach you a simple way to let us know the relative parameters, we can 12 noon sunlight in the case of tests with a multimeter the five parameters (of course there will be such that the measured value of the error).

For single solar cell, it is a PN junction, except when the sunlight above, it can generate electricity, it also has all the characteristics of PN junction. Standard lighting conditions, it rated output voltage of 0.48V. In the use of solar lighting solar components are connected by a multi-chip solar composition.

Users can look at to understand the price of solar cells, solar lighting performance and stability. Here I will charge controller, load, battery, etc. as described.

2 Charge Controller

No matter the size of the solar light, a good performance of the charge and discharge control circuit is essential. In order to extend battery life, it must charge and discharge conditions, restrictions, to prevent battery overcharge and deep discharge. In addition, because the input of solar energy photovoltaic power generation system is very unstable, photovoltaic power generation system in the control than the normal battery charging battery charging control is more complicated. For solar lighting design, the success and failure often depends on charge and discharge control circuit success and failure.

Performance is not a good charge and discharge control circuit, it is impossible to have a good performance of the solar lamps. Charge and discharge controller must have the following characteristics, namely: anti-anti-charge control, anti-overcharge control, anti-discharge control, temperature compensation.

3 batteries

As the input of solar energy photovoltaic power generation system is very unstable, so the general need to configure the system to work the battery, solar lamp is no exception, you must configure the battery to work. Generally have lead-acid batteries, Ni-Cd batteries, Ni-H batteries, which directly affects the choice of capacity and system reliability of the system price. The choice of battery capacity generally follow the following principles: First, to meet the night lighting in the premise, the components of solar energy during the day as store down, but also able to store consecutive days of rain the night lighting to meet energy needs. Battery capacity is too small not to meet the needs of lighting at night. Build too large, the battery is always in the state power loss, impact on battery life, and wasteful.


Solar lighting products are energy saving as the advantages, of course load to energy saving, long life. We generally use direct current energy-saving LED lights and low pressure sodium lamp and so on.

At present, most lawn use LED street light bulbs as a light source, LED long life, can reach more than 100000h, low voltage, suitable for use in solar lawn lights on.

Garden lights generally use LED road lamps and DC energy-saving lamps. DC voltage of the DC energy saving lamp, no inverter, convenient and safe.

Low pressure sodium lamps commonly used. Low pressure sodium lighting efficiency (up to 200LM / W), but low pressure sodium lamp expensive.

Lamp housing

We collected information on many foreign solar light, in beauty and energy between the two, most of them choose energy-efficient. Exterior lighting requirements not very high, relative utility on the line. At present, there are many lamps look very pretty, use stainless steel shell. However, performance in the end what? This brings us food for thought!

A good solar lighting products, the key is system design, what is a reasonable system design? Let us first look at several important factors affecting the system, which is the latitude, the annual total solar array surface radiation, the maximum number of days without sunshine, day and average power consumption of sunshine hours.

Let us imagine: if less than the amount of solar charging, daily discharge would happen then? Rainy days, the system for several years but also lighting it? These questions have to be taken seriously our designers.

Finally, I give you about a simple solar lighting system to determine the performance of the method: First, solar power must be four times higher than the load power over the system to work properly. Second, the load on the battery capacity must be more than 4 times higher power consumption (western region), southern region for more than six times higher as well.
