How to Identify a Qualified Solar Electric Contractor

Finding a qualified solar electric contractor might take more work than people think. Solar energy is no longer so niche that people have a limited range of choices for solar panel contractors. There are going to be some people who enter the field without enough knowledge and expertise now. People who are interested in solar panels Atlanta will need to find the right solar electric contractor.

Using the Right Sources to Find a Solar Electric Contractor. 

Solar panel contractors often connect with one another. People who are heavily involved with the field will spend a good portion of their time trying to help people identify the right solar electric contractor. As such, people really don’t have to start from scratch in this way.

Going to the Geostellar and EnergySage online solar marketplaces can help people narrow down the search. These sources will also be able to give people a wide range of additional resources that will help them with the solar panel installation process in general.

There are also communities online full of people who are enthusiastic about solar energy and who have had professional solar panel installation previously. These people might be able to advise new individuals who are looking for solar panel contractors.

Doing Research on Individual Solar Contractors

In some ways, choosing a qualified solar electric contractor isn’t that different from hiring other contractors. People in the modern world will always look back and try to get a sense of the work history of the contractors that they hire.

Almost anyone who hires anyone leaves a review these days, and these reviews should be relatively easy to find online. Anyone who is interested in hiring solar contractors should research these specific solar contractors.

They should get a sense of what past customers have said about them, specifically paying attention to the quality of the work that they did. Looking at the nature of the complaints of customers is also important. All professionals will attract some negative reviews. In fact, it might be positive if they do, since it makes it more likely that the positive reviews are actually genuine.

If the negative reviews make a lot of specific complaints with detailed anecdotes, it might be worthwhile to listen to them. However, some people will more or less never be satisfied with anything, and they might just generically criticize a professional without giving any specific details. It’s often acceptable to ignore these people entirely.

The Right Qualifications

There aren’t a lot of specific licenses that solar contractors will need. However, there are other qualifications that they should have, such as the North American Board of Certified Energy Practitioners’s (NABCEP) Solar PV Installation Professional Certification . This qualification does only go back to 2002, and it is true that the solar power industry is a lot older than that.

However, even when working with the people who have a great deal of experience in the solar power installation industry, it’s a good idea to rely on the individuals who have up-to-date qualifications and who are able to demonstrate their skills in a way that’s easy for customers to recognize immediately.

Obviously, all solar panel contractors are in need of general liability insurance. They should also ideally have licenses in home improvement and general contracting. Some of them will also have experience as electricians and home repair professionals.

All solar contractors were new at one point. However, the established solar contractors are more likely to provide a superior service. As such, customers should try to find the individuals who have at least five years in the field. The more experience they have, the better. Solar contractors who can talk about previous solar systems that they installed will be able to provide customers with the peace of mind that they need.

These days, solar panel contractors will typically have a lot of photographic evidence of the solar panel installations that they have performed. They should be able to provide a clear record of the work that they have performed in the past.

Solar contractors have every reason to be experienced today, because this is a relatively old field at this point. Lots of people use solar panels Atlanta and get them installed. They deserve the best solar panel contractors today.

What are solar panel kits?

What are Solar Panel Kits?

Solar panel kits are exactly what they sound like: they’re solar-generating systems that people can purchase and assemble more independently than they would otherwise. Solar kits are very popular among the individuals who are trying to live off the grid. Getting home solar panel kits is common for the people who don’t necessarily want to make the upgrade to large-scale solar panels for their homes but who still want to be able to generate their own solar power. Solar kits are also popular among the people who enjoy going camping and who tend to spend a lot of time on RV trips.

Solar panel kits are often distinguished from other solar panels specifically because of the DIY nature of the kits. People will have to hire professionals to install everything otherwise in almost all cases. It is true that the professionals are usually from the solar panel companies themselves. Still, the DIY aspect of home solar panel kits can appeal to a lot of individuals these days. Solar panel kits are broad enough and diverse enough in terms of their characteristics that people should be able to find something that they really want.

Solar panel kits are usually equipped with everything that people will need in order to start producing their own solar power. The solar panel kits do actually contain solar panels. They have the mounting hardware that people will need in order to position the solar panels in a favorable location.

Depending on the model of the solar panel kits, they are also equipped with grid tie inverters that will perform the necessary power conversion, turning DC into AC power from the kit’s solar panels. There are large solar panel kits that are capable of generating DC power only.

The grid tie inverters will also allow for net metering capability. Thanks to the net metering capability, the people who are producing solar energy will be able to take all of the surplus energy that they produce and sell it to the utility itself. As such, a lot of the people who use solar panel kits will be able to offset a good portion of their own utility bills. Depending on the sun coverage that they get and the amount of energy that they are able to generate, they might be able to pay next to nothing for their electric and utility bills as a result.

Characteristics of Solar Panel Kits

1. Solar Panel Wattage

One of the most important things that anyone should keep in mind when evaluating different solar panel kits is the wattage. The wattage makes all the difference in the world when it comes to what people can actually achieve with a given solar panel kit. A 10,140 watt solar panel kit should be able to meet the needs of an entire household, depending on the electricity usage of that household. A solar panel kit that offers 320 watts of power should be able to meet the needs of people who like to go camping, but it will only be able to offset a little bit of a household’s power in most cases.

There are solar panel kits that will go as low as 80 watts or so, and this is for the casual camper or RV driver in a lot of cases. This is not the sort of wattage that will really allow people to offset a good portion of their electric bills. Still, all users are going to have their own needs when it comes to electricity and for power, so the smaller solar panel kit might be the ideal choice.

When it comes to wattage, the majority of solar panels are going to meet between these two extremes. People will still be able to find solar panels that are truly able to meet their needs. Not everyone needs home solar panel kits that will meet the needs of entire large households. However, they still might want to get kits that will correctly meet their needs when they are on camping trips. There’s also the fact that there is no need to assume that it’s ‘all or nothing.’

People will be able to offset some of the electricity that they use with some of these solar panels, and that can be enough to make a difference. If people cannot replace all of their electricity with solar power logistically or otherwise, it still makes sense for them to try to find a way to balance out their power consumption by embracing a greener form of energy that could eventually save them some money.

2. Solar Panel Weight

The solar panel kit wattage is directly related to solar panel size. The bigger the solar panel size, the greater the wattage in most cases. A larger solar panel is going to have more solar cells and will probably be able to harvest the energy more efficiently anyway, taking advantage of its inherent size.

Some of the solar panel kits that people will use will only make use of DC power. This means that they will work well enough, but they will be much more limited in terms of their capabilities in general. People are going to have to either ration the power or rely on these solar panel kits for smaller camping trips or RV trips only. Solar panel kits that will use DC power in addition to AC household power are also available.

People can certainly make use of those, and these will tend to be larger and more expensive. However, they might be excessive for the needs of some people. The size of a solar panel will always matter. For some people, a smaller solar panel is better. For other people, a larger solar panel is better.

As the size of a solar panel increases in terms of its surface area, the weight of the solar panel is going to increase at around the same time. This is the sort of thing that people will have to take into account more if they are trying to choose the solar panel kits that are portable. People going on camping trips will not need solar panels that deliver high wattage, for the most part. This is a good thing, since the solar panels that deliver high wattage are going to be much heavier than people would expect almost exclusively.

People who are trying to meet their household needs with solar power will certainly need to look at the size of the solar panels and they will need to choose the bigger ones. However, people whose preferences are in the middle might have to play some games with cost and benefit analyses in order to figure out which characteristic is more important to them.

3. Solar Panel Cost

The solar panel cost is one of the most important facts when it comes to choosing a solid solar panel kit. It is true that people can use solar panel kits in order to meet all of their electricity needs at home. However, they might pay more than ten thousand dollars for them. Some companies will offer Federal Tax Credits for these solar panels as well, and that is going to make things easier for the people who are trying to find a way to pay for their solar power in a much more responsible and effective manner.

Obviously, most solar panel kits are nowhere near ten thousand dollars. Even a solar panel kit that should allow people to meet most of their household needs might cost as little as seven thousand dollars, which is a decent amount for a product that will continue to generate free energy for years to come. With solar power, the initial installation costs can be pricey, without taking into account credits or any other discount. However, the fact that solar panels are able to keep on producing energy always makes them more cost-effective in the end.

4. Solar Panel Price Per Watt

Looking at the solar panel price per watt can help a lot of people with deciding whether or not a particular solar panel kit is going to be worth it ultimately. This is fairly easy to calculate, although a lot of different solar companies will already do the calculation for customers. Finding a solar panel kit that will cost around 1.77 dollars a watt is common, and it is a good rate. Some of the solar panel kits will cost more than that per watt, and some of them will cost less than that. Finding a high-quality solar panel kit that will cost around 1.50 dollars a watt is still possible.

Solar Panel Kits Comparison

Go Power solar kits are very good choices for the people who tend to take RV trips and who want to be able to produce solar power there. They have solar kits that will generate 80 watts and solar kits that will generate 480 watts, which more or less illustrates the power range that they have. Some of their kits will charge with DC power only, and some of them will use DC power and AC household power. These solar panel kits can also work well enough for the people who are interested in replacing some of their household power with solar power and who are interested in the possibilities involved with that.

Go Power solar kits are also more casual than a good portion of the other solar kits that people can find on the market today, since they were designed for people who have a lighthearted DIY approach to the whole endeavor. Go Power and similar companies demonstrate the fact that solar power and solar panel kits have become much more mainstream in the modern world. These products are not ideal for home solar kits, but they will work well enough for the people who are trying to enjoy a more sustainable form of camping and RV driving. RV driving has its inherent environmental costs. However, offsetting some of those costs with solar panel kits will make this hobby more sustainable, and it does certainly help in a real way.

Go Green Solar is a popular source for high-quality solar panel kits. It’s easier to find solar kits that can meet a broader range of household needs with Go Green Solar. The 10kW PV optimizer kit is a great choice for the people who want to find a way to rely on solar power entirely. This system can be expensive, depending on how people decide to pay for it. However, it is possible to pay less than two hundred dollars a month with Federal Tax Credit eligibility.

Go Green Solar has less expensive solar panel kits that people will be able to use as well, so no one should think that it’s impossible to walk out of there for less than ten thousand dollars. It’s possible to get a 4160 watt solar panel kit for 7,363.20 dollars. This equates to around 1.77 dollars a watt. This is a decent rate for the company, although they have solar panel kits that cost 2.05 dollars a watt and 1.53 dollars a watt as well. It might be possible to find some solar panel kits that are actually less expensive than that, although people will have to pay attention to quality at that point as well.


The solar panel size does matter, as does the price per watt. However, that doesn’t mean that the larger solar panel kits are inherently better than the smaller solar kits or that it works the other way around. Different customers are just going to have different needs, and they should try to choose the size of a solar panel accordingly. The solar panel size is going to have a direct effect on whether or not people are going to be able to get all of the power that they need from the kits. Obviously, the size of a solar panel is just as important when it comes to determining whether or not people will be able to comfortably carry it with them when they are on RV trips or camping trips. People should consider the costs and benefits associated with all solar kit characteristics.

Solar Panel Size

Solar panel sizes


There are lots of different factors to consider when purchasing solar panels. In most cases, people are going to have to consider their own electricity needs before they go about purchasing solar panels. Choosing solar panels according to their size is often a matter of practicality. Customers have to choose a system that is going to work for them and that will successfully meet their needs.

All companies will have their own specific solar panels and photovoltaic cells. As such, people can expect some minor variations when it comes to the length, the width, and the depth of the solar panels. However, the variations won’t be too dramatic because there are some built-in limitations when it comes to the size of solar panels.

They need to be small enough to fit on a building in the case of a lot of different installations. When solar panels are installed in open fields, they might be much smaller than that. However, there will usually be a lot of them in several rows, so these groups of solar panels will be able to generate a great deal of solar power. In this case, the people who install solar panels are really trying to make use of the space involved.

Solar Panel Size

Getting the right solar panel dimensions is essential for the people who are trying to rely on solar energy in order to meet their electricity needs. Residential solar panels often measure 65 by 39 inches. In terms of depth, many solar panels will measure around 1.4 to 1.8 inches. Most of these very same residential solar panels will weigh around 40 pounds.

Finding solar panels that are substantially longer than 73 inches will tend to be difficult for the people who are specifically looking for residential solar panels that are going to conceivably fit on most properties. In terms of solar panel dimensions, the length of solar panels will vary from 61 inches to 73 inches. The width will vary from 39 inches to 47 inches. The depth will vary from 0.22 inches to 1.8 inches. There might be different brands emerging on the market that will be able to give people different results than that. However, most of the modern solar panels are not going to substantially deviate from these solar panel dimensions in a lot of situations.

Structurally analyzing the roof of a home prior to a solar panel installation is important, even though it actually is not a universal practice among the companies that install solar panels. In the United States, this structural analysis is more common in some states than in others. Usually, most roofs can handle an additional 40 pounds.

Since this 40 pound is going to be distributed across the roof, a solid roof that is in good shape will generally not be threatened by the installation of solar panels. Still, it’s important to get all of that test in advance. Homeowners might want to make some additional upgrades to their roofs in terms of structural support before they decide to get solar panels put into place. It’s a good idea to solve all of these potential issues in advance.

Of course, some people would prefer to measure solar panels in terms of the number of photovoltaic cells that they have. Residential solar panel installation will typically have a total of 60 photovoltaic cells distributed evenly across the panel. The most energy-efficient solar panels of all will typically have 96 cell panels, making them significantly more effective at generating solar power. The photovoltaic cells themselves typically measure around 156 square millimeters.

While bigger solar panels are not necessarily better, solar panels that have more cells are often functionally better in terms of the amount of sunlight they can capture and the amount of energy that they can ultimately produce. Solar panels that have more cells are typically larger in terms of surface area at this point in time.

Solar Panel Sizing

There are some variations between residential solar panel installations. There are more variations between commercial solar panel installations and residential solar panel installations. With very few exceptions, the commercial solar panels have a tendency to be much larger than the residential solar panels that people might rely on more frequently.

A commercial solar panel will typically have 72 photovoltaic cells. These commercial solar panels are also longer than the residential solar panels by about 13 inches or so. Of course, solar systems themselves are going to vary much more when it comes to installations for commercial buildings. When it comes to solar panel sizing, people should always ask: how many solar panels do I need?

A solar needs calculator can make all the difference for the people who are trying to get a sense of their actual solar energy requirements. These calculators are widely available online and people should be able to find them easily. Most solar needs calculators are not going to vary all that widely when it comes to the results that they can generate.

People will need to have their electric bills handy, and they will be better off if they manage to hold onto a range of electric bills in order to get a sense of their more regular electricity usage. Solar needs calculators will ask people about the KiloWatt-Hours (kWh) of electricity that they will use in a given month. Averaging the results that people will get from several different electric bills can often help in this instance.

Many of the solar needs calculators online are geared towards the United States. They will often ask people about their home states. However, there are others that are geared towards people in other countries, where some of the rules surrounding the solar installation and solar subsidies might also be different. The location of the house in question does matter a lot, however, because it can determine the level of sun exposure that a given area is going to receive.

People also need to take into account how much they want to rely on solar power in the first place. Offsetting more electricity with solar power is going to end up costing people more money in general. The people who want to manage to offset a lot of electricity with solar power are going to need to have comparatively large solar panels, and this sort of thing can be very difficult with some residences.

These solar needs calculators will not necessarily give people a realistic view of the solar system size that they can expect in a lot of cases, and this is something that all people need to take into account. Getting a 300-watt solar panel installed is going to be common for a lot of people. Getting much larger solar systems installed that will be capable of handling much larger households with more substantial energy needs will tend to be more difficult.

Some households that are trying to offset a large portion of their energy needs with solar energy should really consider whether or not they are going about it in the right way in some cases. They might be better off using less electricity past a certain point. Trying to more or less replace all electricity with solar energy will be tough for most people at this stage, at least until solar panels start to become more efficient. Offsetting some electricity with solar power is a good idea.

However, people might need to try to reduce their consumption of electricity past a certain point as well if they are going to try to be as committed as possible to green living. Still, solar panels are going to become more and more advanced and efficient as the years’ progress, and that is only going to make it easier for people to maintain their electricity consumption while still being able to offset most of it through the use of advanced solar panels.

Residential Buildings and Commercial Buildings

Residential buildings are going to vary substantially when it comes to their size. However, that doesn’t mean that all big houses can necessarily get fitted with solar panels all the way through. Some sections of big houses are going to get the sun exposure necessary to make it all work. Some roofs won’t have the surface area necessary to support really broad solar panels. Houses will also have some decorative or functional features that will tend to interfere with the installation of larger or broader solar panels.

In the case of commercial solar systems, large-scale solar systems are significantly more common. This is partly a function of the fact that many commercial buildings are in need of more electricity, to begin with, and it’s important for businesses to find a way to efficiently mine all of the electricity that they can from the incoming sunlight in their area.

Of course, commercial buildings will also just have large-scale solar systems because they can. They typically have large enough buildings and premises that people will be able to easily install very large and broad solar panels anyway. There’s no reason to fail to take advantage of this obvious and clear benefit. Municipal buildings and warehouses will typically have substantial electricity needs. They will also frequently have solar panels that are as long as six feet.

Commercial buildings will typically vary in terms of the amount of incoming sun exposure that they can attract in the first place. Some of them will have the necessary surface area to truly get the level of sun exposure that can allow businesses to offset a good portion of their electricity usage. It’s also worthwhile to note that a lot of commercial buildings will have a strong budget behind them, and this is going to make it that much easier for the companies involved to get the sort of broad solar panels that are going to truly make a dent in their carbon footprint.

Many businesses are able to get financial support and benefits if they are able to upgrade to using solar panels, which will make it that much easier for them to be able to afford the sort of broad solar panels that will generally help them meet almost all of their requirements.


Solar panels are broad enough and deep enough to be effective these days. The efficacy of solar panels is partly a consequence of the solar panel dimensions in the first place since a sufficiently small solar panel is not going to be able to produce enough energy to make anything count. The solar panel size that people can expect will certainly vary.

Of course, people should consider the size of the photovoltaic cells themselves, which is 156 square millimeters. These cells can only vary so much in terms of their size, which is going to place some upper and lower limits when it comes to the overall solar panel size that people can expect in most situations.

Solar panel weight levels that people can expect are not all that high. A residential solar panel will weigh 40 pounds. The people who tend to be worried that their roofs are going to cave in as a result of their new solar panels should generally not be all that concerned about that. Their solar panels are generally going to be light enough that almost any good roof is going to be able to support them. However, it is still a good idea for people to be able to get their roofs inspected beforehand in order to make sure that there isn’t anything else going on with the roofs or anything that a person might worry about in the long run. Roof inspection in this way is not always mandatory, and ideally, it would be in all situations.

Commercial buildings are going to have larger solar panels with broader dimensions than the residential buildings. However, it’s still important for people to be able to get a sense of the limits when it comes to solar panel dimensions. Using a solar needs calculator can help people determine the size of the system that they need, which will usually fall within certain limits.
