Certified solar energy companies carry out the vast majority of solar panel installations. When hiring a professional solar company, you can either go with a local or national installer.
For more information, please visit our website.
A local solar installer will usually be able to offer you more personalized service, more affordable prices and more intimate knowledge of local solar incentives and policies. Ultimately, this could end up saving you more or helping you get more value out of your system. The flip side is that nationwide installers can often have access to a wider range of solar products, like the most efficient solar panels and the best solar batteries in the industry, and they often buy materials in bulk and can pass those savings onto you as the customer.
This can give you more options to maximize the power output and durability of your system, too. There’s not really a right or wrong answer here, and in fact, the best approach may be to consult with two or three installers that service your area before making your decision.
Installing your own solar panels provides the opportunity to save money on labor and also gives you greater control over the final configuration of your home solar system. Be aware, however, that there can be significant downsides to do-it-yourself solar jobs.
First, it is complex, technical work, requiring electrical expertise and thorough knowledge of how solar works. If you’re unskilled or inexperienced in working with electricity, installing solar panels presents concerns to both your safety and the integrity of your roof and electrical system.
Additionally, going with DIY solar panels means you won’t reap the benefits of experienced solar designers, who can help you design the optimal energy-generating, money-saving system. If you do choose to buy solar panels and install them on your own, you can purchase panels from:
Finally, DIY panels tend to have efficiency ratings that top out at 18% and average around 15%. This pales in comparison to the 22.7% maximum and 20% average from professionally-installed panels. Overall, you’ll see more value from professionally-installed panels because they’ll offset more or your electric bill. It will cost more upfront to hire a pro, but you’ll usually save more — an average of $31,513 after the system pays for itself — in the long run.
Now you know where to purchase panels, but as for how to buy solar panels, your next steps will again depend on whether you hire a professional or go the DIY route.
For most of our readers, we recommend hiring a solar installer that will plan your system and purchase the solar equipment on your behalf. Note that installers buy in bulk and have access to wholesale prices, so they can actually help you save money on your equipment costs, though of course, you’ll then have to pay for the labor. The general steps in the process are as follows:

If you’re a more qualified homeowner looking to research, design and install your home solar system, you’ll need to purchase equipment on your own. First, determine how many solar panels your home requires.
This hinges on an array of factors: the amount of electricity your household consumes, the surface area available on your roof, the amount of sun exposure your roof receives and more. The number of panels you need will vary wildly, but the table below includes a quick look at some estimates based on monthly electricity consumption.
Monthly Electricity Consumption Average System Size Required Average # Panels Required 600 6 kW 16 700 7 kW 19 800 8 kW 22 900 9 kW 24 1,000 10 kW 27 1,100 11 kW 30 1,200 12 kW 32For residential installations with limited roof space to work with, we recommend looking into highly efficient solar panels. This will ensure your investment is worthwhile. (We’ll get more into the different types of solar panels below.) Also, remember that designing a solar system requires a lot more than just panels. Consider what equipment you’ll need before purchasing your solar panels.
Do you want a string inverter or microinverters? Do you need a battery? A charge controller? (We’ll also get more into this later on). Even if you carry out your own installation, you’ll still need to apply for any necessary permits and interconnection agreements. In the event you perform an off-grid installation, you may not need permission from your utility.
There are three basic types of photovoltaic panels available today: monocrystalline, polycrystalline and thin-film. The factors differentiating these options have to do with the efficiency, flexibility, solar cell makeup, size and cost of the solar panels. These can all impact which solar panels you purchase.
Solar Panel Type Advantages Disadvantages Monocrystalline solar panels Highest efficiency and best performance Highest upfront cost Polycrystalline solar panels More affordable than monocrystalline Lower efficiency than monocrystalline Thin-film solar panels Portable and flexible Lowest efficiency and power outputAn important note we’ll repeat: For homeowners with a limited surface area on their roofs, efficiency is the name of the game. Make sure to buy solar panels with high efficiency ratings, as this will maximize the sunlight available to you, making your investment more worthwhile. Most of the best solar panels will be monocrystalline.
Panel efficiency is likely going to become even more important than it is now once net metering 3.0 is adopted throughout the country. This change to the net metering policy will reduce the credit rate for every kWh you export to the grid, so you’ll need higher production rates and exportation rates to break even. In most cases, you’ll also need batteries to see significant savings, at which point high-efficiency panels can help keep them charged and ready to support your home’s consumption at night or on cloudy days.
If you’re doing your own installation, you’ll need to consider purchasing the following when you buy your solar panels:
Installing solar panels involves a number of decisions, starting with where to buy your panels. Are you qualified to install solar panels yourself? What type of solar panel is best for your energy needs? What other equipment will you need to buy along with your panels?

Make sure you do your research and hire a vetted, experienced solar contractor with a track record of success. Ask any friends or neighbors with solar who they hired and how their experience was. Some solar companies have programs that reward $1,000 or more for referrals. You can also continue your research on the best solar companies, or look for local solar installers in your area.

Generally, one pallet has from 25 to 35 solar panels in it — sometimes more. The number depends on the manufacturer. Whenever we put out a solar panels pallet for sale, we always specify the number of PV modules inside.
One pallet of solar panels is more than enough for a standard residential system. Even by ordering just one, you can build a commercial-scope system with it. Let’s say, you’ve ordered 30 panels with an output of 450 watts. You’ll be able to construct a 13.5-kilowatt system with it.
As it is common with PV modules, the price of pallet of solar panels depends on brand and country of origin, the power output of a single panel, warranties that the manufacturer offers and the way you want to get the order: shipping or pickup.
When it comes to brands, Chinese solar panels and those from ASEAN countries are the cheapest by far. Asian manufacturers aim to make their panels as cheap and efficient as possible. Look for brands such as Jinko Solar, Trina Solar, Longi Solar and JA Solar.
North American brands offer better quality and sometimes the panels are easier to get. The solar panels pallet pricing from them is a bit higher though. The most famous brands are Mission Solar, Canadian Solar and Silfab.
Then there are big names like Panasonic from Japan, Norwegian REC, Meyer Burger from Switzerland. They offer the best quality and the best warranties. However, their panels are the most expensive on this list. Remember though that a pallet of solar panels for sale is going to be much cheaper than buying PV modules one by one.
