15kw solar system

Solar power can be a great asset for your business. It lowers or straight up nullifies your electric bills, brings you money through net metering and improves the public image of your business. A solar system is made out of several components and you have to size them together correctly so that they work well as one entity. At A1SolarStore we offer complete 15kw solar systems for sale where all the parts are already picked by our engineers.

What is a 15kw solar kit

The majority of commercial-scope systems are grid-tie which means that you retain the connection to the grid when you add solar. Your appliances use solar energy all the time so that your bills decrease significantly. You can even sell extra energy into the grid for credits from the utility if the net metering policy of the state allows you to do so.

So how much power does a 15kw solar system produce? A lot depends on the positioning of your panels, weather and most importantly, the number of sun hours in your area. You can expect anywhere from 50 to 85 kWh of power per day. That’s enough for any large house or a small business, like a cafe, shop or a gas station.

Grid-tie systems require panels and an inverter. You can also go for hybrid variation or 15kw off grid solar system. In this case your system will also have batteries that will be your backup for a power outage. Hybrid systems allow you to retain the option of a net metering but with an interrupted power supply as well. Some ask, how many batteries for 15kw solar system do you need? That really depends on you and your needs. Generally, people get enough batteries to either survive a blackout or to have a steady power supply for at least one day without grid connection.

15kw solar system cost

Panels are going to play a big role in your system’s production and its cost. Generally, large systems, such as a 15 kW one, are installed on the ground and you use 72/144-cell panels or even bigger ones to build it. Chinese PV modules (Jinko, JA, Trina Solar) are the cheapest. North American panels (Silfab, Canadian Solar and Mission Solar) are a bit more expensive but the quality is higher overall. Panels from companies Panasonic, LG, REC show great production levels and come with great warranties but going for them will increase your final 15kw solar system price.

The configuration also has its impact on the cost. Grid-tie systems are the most simple ones: you only need panels and an inverter as essentials for it. Net metering, if available, provides a steady income and makes the system pay for itself in 6-8 years. A 15kw solar system with battery backup, off-grid or hybrid, is significantly more expensive, primarily because of the batteries. However, sometimes a hybrid system pays for itself quicker because energy storage helps to avoid peak energy rates from the utility.

The number of variables make it harder to answer how much does a 15kw solar system cost. A lot depends on solar incentives that you will or will not be able to get. The most important one of them is the Federal Solar Tax credit: you can deduct up to 26% of your installation costs from your taxes. The reduction includes things like shipping and labor expenses. Consult with your installer about possible solar incentive programs that you can apply for.

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.
