20kw solar system

The energy needs of a business can be significant, but a PV installation may be an answer to your problems. A 20 kw solar system will cover, at least partly, the energy consumption of your business and pay for itself in less than a decade. At A1SolarStore we offer complete systems where all the components already go well together.

What is 20 kw solar system

Commercial solar systems are for the most part grid-tied and they are often installed on the ground, since there isn’t enough space for the modules on the ground. A 20 kwh solar system is usually built out of large 72/144-cell or 96-cell PV modules. These panels are over 400 Watts in output. You would need a substantial amount of modules to construct a large PV installation: for example, you could use fifty 400W solar panels.

Ground-based installations are usually slightly cheaper to install than rooftop systems. It is also easier to get the best positioning and angle for your modules. However, land installation requires quite a lot of space (the exact 20kw solar system size will depend on the modules that you’ll choose). You can choose bifacial modules with an active rear side to save space. Bifacial panels provide up to 33% bonus production, if installed correctly.

How much power does a 20kw solar system produce? A lot depends on the positioning of your panels, their properties, shading and number of sun hours in your area. Generally, the number of peak sun hours ranges from 3 to 6 per day. In the summer panels produce 50% more energy than in winter. For instance, in June a 20 kilowatt solar system in Los Angeles may produce from 100 to 120 kWh of power per day.

While grid-tie configuration is the most common choice, you can also get a 20kw solar system with battery storage. A battery bank will keep your house or business project powered during power outages. A hybrid system ensures uninterrupted power supply which is important when you can’t risk losing the results of your work over a blackout.

20kw solar system cost

Panels play a big role in your system’s production and its cost. Generally, Chinese PV modules are used because of their low cost and high efficiency. The most famous brands from Asia are Jinko, JA, Trina, LONGi Solar. North American panels are also a good choice: they are a bit more expensive but the quality is higher overall. Companies like Panasonic, LG, REC offer premium-class panels primarily for residential systems so going for them will greatly increase your future 20kw solar system price.

Grid-tie system is the most simple and the cheapest configuration — it only requires solar panels and an inverter (possibly, several units). The cost of a 20kw solar system with batteries for hybrid or off-grid variations is going to be significantly higher. Lead-acid batteries are cheaper, but lithium-ion ones allow for deeper discharge, last longer and are more efficient.

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.
