Sizing your residential solar electric system is all about determining the right solar fit for your house.
Converting the total energy target we have in kWh to the power capacity we need in kW requires a bit of math. Now that we know our target size of 4 kW, the next step is to determine how many solar panels we need. Aside from the power needs used to determine the number of solar panels, you must also consider the physical size dimensions. Although the total area of the 16 panels for our 4 kW system is around 280 square foot, the actual area needed on your roof will be slightly greater since we need to account for spacing between panels, necessary for mounting. Commercial panels have slightly different power ratings and physical dimensions than residential ones. When it comes to portable solar panels, it's really difficult to talk about a typical dimension. The process of installing a solar energy system on your property should follow a relatively consistent path. Solar Selections brokers utilise an approach that ensures correctly sized systems are installed for our clients by identifying the project’s aims and priorities first and foremost. A solar energy system installed in the UK will generate on average 2.2kWh per 1kW installed per day. Budget – Solar energy is an investment, Prices increase somewhat proportionally with system size, however this is not a perfectly linear relationship.
The FiT – There is an absolute cap on the tariff of 50kW installations currently in the UK. By keeping these considerations in mind whilst working towards the goals you’ve established yourself the appropriate sized solar energy system can begin to materialise.

The Solar Tube Company has a full range of Photovoltaic panels both Mono and Polycrystalline. From small portable units to megawatt scale utility projects, there are myriad solar applications using thousands of different solar panel models.
These terms come up in Sunmetrix as well as other online resources, and it can get a bit confusing. Are you interested in reducing your energy bill, neutralizing it, or generating excess energy to sell back to the grid? Most solar panels used for residential rooftop installations are in the 230 - 300 W DC power range.
If the quality and the price are right, you can definitely choose a less efficient solar panel brand, however you will probably need to purchase more units to meet the same system size target. Solar installers normally perform a detailed structural assessment of your roof to make sure that the design is optimized for the available space and the weight of the overall system is distributed evenly across your roof.


Commercial panels are manufactured using a larger number of solar cells (up to 96 per panel) and therefore they are taller. If all you need is a few watts of portable power, then you should go for a small solar panel with a few solar cells.
Investing a solar system is a wise decision, A small solar system or distributed generation can produce reliable, emission-free energy for your home or business, It is important to make sure that you solar photovoltaic system is correctly sized, sited, installed and maintained, in order to maximize your energy performance.
The variety of panel brands, inverters, installation companies and electricity retailers paying your tariffs may differ, but the essential points of establishing feasibility and suitability should always be present. We here at Solar Selections believe in a comprehensive service in detailing such aspects, so please click here for an article on the FiT, here for one on roof mounting and here for ground mounted guides.
After all, a system too small for your households energy use may not have the impact that was desired and an oversized quote can come in over budget and even too large for the roof. This figure can be used as a guide, your Solar Selections broker (Contact us here) will send you a thorough breakdown specific to your address and installation conditions.
Commercially it is more appropriate to consider what large scale systems will save the site over similar lengths of time. As a general guide, most 180-200 watt monocrystalline and polycrystalline panels will require approximately 27 square feet (8 square meters) per 1kW of installed system. Going larger than this will require negotiation with power retailers, something Solar Selections Commercial have been doing for years. Remember that it’s not an exact science, and even with a ballpark figure in mind you can source quotes in that area to move your project forward. They are sliced from a large block of silicon which consists of a large number of crystals.
In this instance a thin film of amorphous (non crystalline) silicon is placed onto a wide choice of surfaces.
Our manufacturing facility manufactures the Caymax brand of panels as well as offering a full size range of panels which can be manufactured on an OEM basis. Each option will entail a different solar panel system size. One of the first steps in system sizing is to get a very good handle on your energy consumption. However, certain manufacturers, such as Sanyo and SunPower, offer more efficient solar panels that for the same physical size can provide up to 345 W DC (if you would like to learn more about solar panel efficiency, check out an article we wrote earlier).
In order to determine the exact number of panels on your roof and their configuration, installers perform detailed calculations. All those solar cells, the casing and the glass cover can weigh quite a bit: the weight distribution of solar panels is around 2-4 pounds per square feet (not very light, but easily within the safety limits of most roofs). Typical dimensions are 77 inches by 39 inches. The installation method used for commercial panels is quite different from that of residential panels.
The power capacity of portable panels is generally lower than the capacity of their residential and commercial cousins. If you are interested in a residential solar installation, chances are you will be using similar solar cells, but you will need a whole bunch more. This article will follow on from previous entries regarding feasibility, taking off at the point where a property owner has established initial viability and is now curious how big a system to consider installing. A commercial installation on the other hand is considered in largely investment terms, delivering the highest amount of return on investment in the fastest turnaround period.
The solar Feed-in Tariff does step down in increments based on how large a system is installed, with the best rates available for systems equal to or less than 4kW in size. As a general rule the bigger the system, the better the procurement costs per kW and the larger the earnings, so minimum size isn’t the guiding light in the commercial sector.


The minimum distance maintained between the edge of the roof and the start of the panels should be 12 inches (30 centimeters). The best advice we can offer is to contact one of our commercial brokers and explore the prospects from there. The appearance of these panels is speckled due to the material and again need to be mounted in solid frames.
Due to the nature of the cells they are flexible, and can therefore be manufactured onto a flexible layer to create a flexible panel.
The brands available include Sharpe, Sanyo, Kyocera, Isofoton, Yingli, Solon, Eurener, CSG, Inventux, First Solar, Nexpower, EPV, and many more.
Before we start, we should mention that we'll cover size in both senses of the word: from a power capacity point of view (as in 200-watt panels) as well as the physical dimension of the panels. Solar cells are connected in series in a solar panel, and solar panels are connected to form an array. A quick look at your monthly utility bill will show you your average energy consumption in kWh (utilities may provide you either with daily or monthly average figures). Note that the DC output values are based on laboratory conditions (also called standard test conditions), when the panels are outdoors and exposed to the elements with ever-changing solar radiation conditions, the output levels may be slightly lower than the advertised amounts.
But you can get a pretty good idea if you can combine the information from the system size we discussed above with the physical dimensions of the panels you are interested in. Let's take a look at an example to better understand how all of these numbers are related to each other.
Visiting Sunmetrix Discover is a great next step in your quest to determine the best size for your needs and to see how many kWh you can generate at your location. On the ground, panels are installed in rows that avoid shading one another, and are usually aligned in a landscape fashion. Most commercial properties have flat rooftops, therefore non-penetrating, ballast mounts are preferred. As a result, the amount of power you can generate from portable panels is generally quite a bit lower than for rooftop installations. Spaces again will differ considerably from quote to quote, so contact us today for some quick and useful information. Power output can reduce in the first few months of use, so quoted output should reflect this fact.
The weight is 42 pounds which translates to a pressure of 2.3 pounds per square foot, so most roofs should have no trouble accommodating the panels and the racking system.
This technique is less invasive than bolting the racks on the roof surface and it also saves several weeks in installation time. Portable panels can be used without an inverter to charge most USB and 12 V devices such as cellphones, GPS units, music players, etc. You can read a previous article we wrote to learn more about how cells, panels and arrays are related. A 7-watt capacity is puny compared to the 250-watt residential panels we discussed above, but if all you need is on-the-go power to charge your mobile devices, it may be all you need. Keeping your connection to the grid will help you balance your consumption and solar electricity generation on an annual basis.
