Roof top solar systems
Roof is a natural place for homeowners to put their solar panels at: it is well-illuminated and it is usually not used for anything else. As long as your energy needs aren’t too high, a roof mounted solar system is a great solution for your house. At A1SolarStore we offer complete systems where all the components are already sized together. You can pick a system of your preferred design: grid-tie, hybrid or off-grid.
Advantages of a roof-mounted solar system
- House roof is rarely used for anything and putting solar panels up there is an efficient usage of your available space.
- Solar panels are sturdy: they protect the roof from harsh winds and storms, and prolong the lifetime of your roof.
- A roof-top solar system requires less maintenance: panels get dirty slower and rain washes away most of the debris.
- Shading is less of a problem with systems on a roof.
Disadvantages of a roof top solar system
- More expensive and difficult to install than a ground-based installation.
- It’s harder to get perfect positioning with solar panels on the roof than with PV modules on the ground. Thus if your roof doesn’t have a good configuration for solar panels, the production of your rooftop solar system might be lower than that of a ground-based system of the same capacity.
- Harder to access, maintain and service since all of your PV modules are on the roof.
- There is only so much space on your roof: it is usually not possible to build a high power capacity system on top of your house.
Roof mounted solar system cost
The cost of your system is going to depend primarily on its size: not only the more watts your kit has, the more expensive it is, it also gets more pricey to install. Picking quality racks, frames, screws and fasteners also becomes very important for roof mounted kit.
Panels and inverters impact the cost of your system as well. When it comes to panels, Chinese are the cheapest. American PV modules are slightly more expensive and of a higher quality. Also there are brands with premium-class panels for roof mounted solar systems for home, such as REC, Panasonic, LG, Solaria. When it comes to inverters, string ones are the most common pick. Microinverters are slightly more expensive, but they last longer, they deal with shading better and they are more efficient.
Don’t forget to apply for different solar programs and incentives — in the end they might reduce your final roof mounted solar system price by a fair amount. Consult with your contractor about programs that your system might be eligible for. Always apply for Federal Solar Tax Credit: you deduct 26% of the costs of your system from your taxes.

Frequently Asked Questions
How do I choose the right system size?
Your utility bills contain the energy consumption data for your home. All you need to do is divide the daily figure by the number of peak sun hours in your area. The result will be a gross estimate of a system size needed to offset 100% of your energy needs. Please refer to our article on sizing solar panel systems for more detailed instructions.
How do I know if a system is good for my house?
You can browse through our catalog and pick a system with desired power output and functionality. Our engineer with 20+ years of experience will adapt it based on the information you provide. He will take into account your location, roof pitch, house orientation and other factors. You don’t need to know a single thing about solar – we will support you at every stage.
Which system (grid-tie, off-grid or hybrid) will work for me the best?
It is impossible to give a good recommendation without knowing any details, but we can share the general principles. A grid-tie system is the standard choice: it is the most affordable and lets you take advantage of net metering. You need an off-grid system if the grid is unavailable or full independence is desired. A hybrid system is a mix of the two, performing equally well with and without a grid connection. You can find a more nuanced take on the difference among the three types in our article.
Does a solar system include all that is needed for installation?
Yes, our systems include absolutely all components. You won’t need to buy any extra parts to install it and start generating power.
Will you install the solar panel system for me?
Currently we do not provide installation services. You will need to contact an independent solar installer.
Do you offer a warranty for your solar panel systems?
All components of our systems come with a manufacturer’s warranty. We also stand behind the work of our engineers who configure the systems and guarantee full compatibility.
How can I get my system?
We work with the top freight carriers like XPO, FedEx, ODFL, R&L, etc. We also offer a free pickup option so that our clients could get the equipment cheaper and faster. Note that pickup is dependent on the availability of equipment in our fulfillment centers, and may not be feasible in your location.
Do deliveries of solar panel systems take longer?
We deliver our systems as fast as the rest of our equipment. Typically it takes 5 to 7 days.
Do you have all the displayed systems in stock?
Yes, we offer full transparency and update the availability of items in real time.
What is the benefit of buying a solar panel system compared to buying all the equipment element by element?
Our systems are configured by an engineer with more than 20 years of experience. We will adapt the kit to your conditions and ensure compatibility.
Does a solar panel system come with a plan or a manual?
The equipment manufacturers normally provide user manuals for their products. These can be accessed via our website or the official websites of the respective manufacturers. Aside from that, we do not provide any other materials, but we're ready to consult you along the way.
