4000-watt solar panel kit

Don’t think that a tiny house and solar panels are incompatible. A 4000-watt or 4-kW solar panel kit may be the best solution because it doesn’t take up much space, is affordable, and yet can significantly reduce your energy bills or even make you completely energy independent. 

What’s in a 4000-watt solar panel kit?

A 4000-watt solar panel kit is a comprehensive package that includes everything you need to harness the power of the sun. Let’s take a closer look at its essential components:

  • Solar panels: The heart of the kit, solar panels convert sunlight into electricity.
  • Inverter: Solar panels produce direct current (DC) electricity, which needs to be converted into alternating current (AC) for household use. The kit includes an inverter that performs this vital conversion, allowing you to power your appliances seamlessly.
  • Batteries: In an off-grid or hybrid system, batteries play a crucial role in storing excess energy generated by the solar panels. These batteries ensure a continuous power supply even when the sun goes down or during cloudy days.
  • Charge controller: A charge controller regulates the flow of electricity between the solar panels and the batteries. It prevents overcharging and safeguards the battery’s health, ensuring maximum efficiency and longevity.

Grid-tied, off-grid, hybrid systems

A 4000-watt solar panel kit offers versatility and can be used in grid-tied, off-grid, and hybrid systems.

  • Grid-tied: Grid-tied systems are a popular choice for small houses with access to the electricity grid. With this setup, your solar panels are connected to the utility grid, allowing you to use solar energy and draw power from the grid whenever needed. When your solar panels generate more electricity than you consume, the excess power can be fed back into the grid, earning you credits or reducing your overall energy bill.
  • Off-grid: If you’re living in a remote area or simply desire complete energy independence, an off-grid system is the way to go. With a 4000-watt solar panel kit, you can power your tiny house without relying on the grid. The excess energy generated during the day is stored in the batteries and used during the night or when the sun isn’t shining. Off-grid systems offer freedom from utility bills and provide a sustainable energy solution.
  • Hybrid: For those seeking the best of both worlds, hybrid systems offer a hybrid approach. These systems combine elements of both grid-tied and off-grid systems, allowing you to enjoy the benefits of grid connection while having backup power during grid outages. In a hybrid system, excess energy is stored in batteries for later use, and any shortfall is supplemented by the grid. It provides flexibility and resilience to ensure uninterrupted power supply.

How much does a 4000-watt solar panel kit cost?

The price of a 4000-watt solar panel kit can vary depending on the brand and additional components included. However, prices have significantly dropped in recent years, making solar energy more affordable than ever. Additionally, the savings you’ll achieve on your energy bills over the system’s lifespan can outweigh the initial investment. Generally, you can expect to invest between $10,000 to $25,000. 

Many governments and local authorities offer incentives to encourage the adoption of solar energy. These incentives may include tax credits, rebates, and net metering programs. By taking advantage of these programs, you can further reduce the overall cost of your solar panel kit and shorten the payback period.

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.
