7kW solar system

When you want to build a solar system for your house or business, it’s important to size together all the components of it. For a newcomer to solar energy and electrics, it might come off as a challenge. At A1SolarStore you can order a complete solar system where all the parts fit together well.

A 7kw solar system, grid-tied or off-grid, is a smart energy solution for a medium-size or large house. It should be able to cover up to 100% of your energy needs, especially in a sunny place.

How much does a 7kw solar system produce

The production that you can expect from your PV installation depends on your panels just as much as on the set of external factors. Here are the most impactful factors that you should look out for:

  • Weather and hours of sunlight. Panels keep working when it’s cloudy, but their performance drops by 20-40%. Some areas get more sunlight than the others, and the more sunlight the system gets, the more it produces.
  • Positioning. If you live in the US, turn your panels to the south. An angle can be equal to your latitude or you can just set it between 30 and 45 degrees. It is easier to set up a 7000 watt solar system on the ground perfectly but it will require more maintenance.
  • Shading. One shaded cell of a solar panel can shut down a whole sector of a module. Moreover, the performance of every panel drops to the level of the weakest link, if you’re using a simple string inverter. Add solar optimizers to decrease the impact of shading on your system.

So how much power does a 7kw solar system produce per day? It depends on the number of peak sun hours in the area. For instance, the average number throughout the year in California is at 5.6 hours. Thus, a system makes close to 40 kWh per day. Keep in mind that a system makes 50% more energy in summer than in winter.

7kw solar system cost

The drawback of a solar system is a somewhat high upfront cost. However, this problem can be avoided by applying for incentive programs and getting special solar loans at a low interest rate. By selling energy into the grid, you gain money with your system and eventually it pays back for itself. The average ROI time of a solar installation in the US is 6-8 years, whereas the average lifespan of solar panels surpasses 25 years.

The cost of 7kw solar system highly depends on the panels that you’ll choose. You would need from 15 to 25 panels to build an installation. Chinese panels from brands like Jinko, LONGi, JA, Trina Solar are the most affordable. The PV modules from NA brands are slightly more expensive but their quality is higher. The most efficient and reliable but also the most expensive panels come from manufacturers like REC, Panasonic, LG, Sunpower.

The overall 7kw solar system price can vary from $8,000 to $15,000, including shipping and installation services. You should always take advantage of the Federal Solar Credit program which is available in all states for owners of residential and commercial PV installations. It allows you to receive back 26% of your 7kw solar system cost through taxes. It makes sense to hurry: in 2023 the percentage drops to 22% and in 2024 and subsequent years it falls to 10% and applies only to commercial systems.

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.
