Going solar doesn’t mean a huge field of solar panels or a house that is covered with PV modules. Sometimes all you need is a small solar power system. It won’t cost much, but still can help to lower your energy bills and therefore will pay for itself in a few years.

The average power capacity of the solar system in the US is 5-6 kW. Sometimes it covers up to 75% of electricity needs of a medium house. A system pays for itself in 7-8 years on average, though it happens faster in states with a lot of sunlight, like California. The main way in which a solar power system for small home pays for itself is through a net metering program. While panels power all the appliances in your home, you send the leftover solar energy into the grid where it can be used by someone else. Your utility in return provides you credits that can be used to pay your bills. 

The aforementioned type of system is called grid-tie: you make use of your solar system, but stay connected to the commercial grid at the same time. Other configurations are called off-grid and hybrid. Off-grid design implies the usage of energy stored in batteries since you aren’t connected to the grid. A small solar power kit can be a great choice to make an off-grid system for RV or a boat. Hybrid system is a grid-tie system with batteries on which you can rely on in case of power outage in the grid. They are a good choice when uninterrupted power supply is important for you. 

A grid-tie small solar power system kit includes solar panels (generally 10-25, since we are talking about small installations) and a standard string inverter. You can also go for microinverters: they are efficient, long-lasting and very easy to install, but they are a bit more expensive, and the possible maintenance can be a bit more problematic.

When we talk about mobile solar installations for trailers or boats, a small solar power system consists of only a few panels (for example, you can’t really fit more than 5-6 modules on your RV), house battery (sometimes your vehicle already has one), charge controller for the safety of your battery and an inverter if your appliance need direct current. This installation would be considered off-grid, so you’ll need an appropriate type of inverter.

We offer a variety of small solar power kits in which all the components are already sized together. Our customers find them much more convenient than picking solar panels themselves and then trying to calculate the size of the inverter or, possibly, the battery. You can use our solar calculator to design your own system. Enter your location, pick your solar panel of choice, choose the inverter and the tool tells you the area that your system will need, potential savings and an approximate small solar power system cost.

Don’t hesitate to contact us for any questions. Our staff will be glad to help with your order. Here is how we operate:

  • Our warehouses are located on both east and west coasts of the USA: California, Washington, Colorado, Texas, Florida, New Jersey, and Missouri
  • We process all orders within 24 hours and ship them within 48 hours
  • Delivery normally takes between 4-7 business days
  • All of our suppliers are trusted solar panel manufacturers
  • We offer competitive and affordable small solar power systems prices.

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.
