70kW solar systems

If you want to build a powerful solar system for your business or residence, this is the place where you can one. A 70 kW solar system provides you with a steady supply of energy and significantly lowers or straight up nullifies your bills for electricity. At A1SolarStore you can get a complete solar kit where the components already fit together nicely.

What is 70 kW solar system

Systems of a commercial and industrial scope are generally installed on the ground because there is just not enough space for putting all the modules on the roof. There are three types of system configurations and thus three types of kits:

  • A grid-tie 70 kilowatt solar system is the most simple configuration and the most popular one as well. The commercial grid is available to you and you can either draw energy from it as usual or pump your excess solar energy into it, selling it to your utility and making your electrical meter go backwards. It’s called net metering.
  • Hybrid 70 kwh solar system includes a hybrid inverter and energy storage. It's a good option if power outages are frequent in your area. When a blackout happens, a hybrid inverter switches your house to battery support.
  • Off-grid configuration of a 70kw solar system with batteries generally is used when the connection to power lines is not available. You rely solely on solar power during the day and on batteries at night. It is a rarity: large battery banks are expensive and net metering is not an option in this case.

When it comes to production, you can expect hundreds of kilowatt-hours per day from such a system. However, the exact amount of energy that a 70kw solar system produce per day will depends on the following factors:

  • weather in your area;
  • positioning and tilt of your panels;
  • shading;
  • number of peak sun hours in your location.

California gets around 5-6 peak sun hours in summer. A 70 kilowatt solar system will produce around 350 to 420 kWh per day. At the same time in New York the same system will perform significantly worse, especially in the winter, because the number of sun hours will be around 3-3.5.

Your 70kw solar system size and the area that you’ll require for your installation will depend on the panels that you’ll choose. Generally, 72/144-cell, 96-cell or larger panels are used in commercial systems and the output of one panel is from 400W to over 600W. It means that you’ll need from 110 modules and up to 170 to build a 70000 watt solar system. Bifacial panels can help you save space: the active rear side of the bifacial panel gives up to 33% production bonus to the front side. However, you’ll have to install them correctly to increase the albedo of a surface and bifacial gain.

70kw solar system cost

Solar systems of commercial and industrial scope take a long time to build: from several months and up to year. The cost of a 70kw solar system will depend on configuration of your system, solar incentives, labor expenses, permits that you’ll have to get and the panels that you’ll choose.

When it comes to systems of a large size, Chinese solar panels are the most common choice because of their low cost and high efficiency. North-American PV modules are slightly more expensive, but the quality is higher on average.

The design also impacts your 70kw solar system price. Grid-tie installation is the simplest and cheapest, plus it provides a steady income if net metering programs are available. Since energy gets more and more expensive and panels on the contrary get cheaper to produce, you can expect the system to pay for itself at least a couple of times. The 70kw off grid solar system price is going to be much higher since a system of this scope usually requires a large energy storage.

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.
