Solar systems with string inverters

Solar systems with string inverters are the most popular choice among our customers. They are the most affordable, and perform very well in a typical residential installation. In a nutshell, string inverter systems consist of 3 to 6 strings, with each containing up to 12 solar panels. Typically, each string has a dedicated controller inside the inverter. This allows to maximize performance by applying different settings to each of the strings. It could be particularly helpful if the strings are installed on different sides of the roof or at different angles.

The pros and cons of solar systems with string inverters

String inverter solar systems are contrasted with microinverter-based options. Those implement a fundamentally different approach, employing a separate small inverter for each of the panels in a system. Here are the main advantages of string inverter systems:

  • Ease of maintenance. A single inverter in an accessible location is much easier to troubleshoot than dozens of inverters on the roof
  • Price. Solar systems with string inverter cost significantly less
  • Proven reliability. String inverter solar systems have been tested for decades

There are scenarios where solar systems with string inverters wouldn’t be the most optimal choice. Here are their main weaknesses:

  • Central point of failure. If a string inverter fails, the whole system is ground to a halt
  • Upgradability. Solar string inverter systems are not as easy to expand unless an oversized inverter is chosen beforehand
  • Shading resistance. With a string inverter, a single shaded panel will affect the whole string

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.
