Adding Solar Panels to Existing System – The Beginner’s Ultimate Handbook

Adding Solar Panels to Existing System

We at ozarksnewenergy.com believe that every person should have access to clean, renewable energy and that solar should be an affordable option for everyone.

Whether you are interested in saving money, protecting our planet, or reducing your carbon footprint, we can help you find the right solution. 

I don’t know exactly how many panels you have; but if you want some sound options on adding solar panels to existing system, you should be able to locate suitable ones for your system.

Adding Solar Panels to Existing System – What to Know Before You Start

Adding Solar Panels to Existing System

You can use two different panels, though I recommend panels with different peak power ratings (peak wattage).

There is no denying that the solar power industry has grown tremendously.

The benefits of solar power are obvious, so why not consider a solar power system for your home?

A sound solar power system will provide free, clean, renewable energy.

In fact, in some states, solar energy is now the cheapest form of electricity.

Since they can generate their own power for nothing, solar consumers tend to be less concerned with their overall energy consumption.

Increasing the number of panels you have installed may be necessary if you start leaving your lights on more often.

If you’re adding a lot of panels and your overall solar panel system is significantly more significant than the original, it may create more power than your preexisting inverter can manage.

There are a few advantages to using microinverters instead of a power optimizer or string inverter for your original solar panel setup.

There is no need to worry about inverter capacity issues since microinverters are located at each panel, and more microinverters may be installed with additional panels.

An upgrade to an inverter and subsequent re-application for connections may result in complications since incentive amounts are related to the amount of electricity your system produces.

Your solar installer can assist you in determining whether or not your add-on solar project is eligible for any financial incentives, and you may want to see a tax professional or accountant determine if there are any tax credits or deductions available to you.

What to Consider Before Installing Additional Panels

Solar panels installation is not a simple process for a small company, as every business owner knows.

Does your property allow for the installation of extrasolar panels?

Depending on the size of your rooftop installation, the answer may be no.

Because property owners with ground mount systems often have many sunny areas accessible for installation, ground mount systems may be simpler to expand.

Microinverters, rather than a power optimizer or a string inverter system, make installing more solar panel systems easier.

Because a professional build microinverters into the panels themselves, you won’t have to be concerned about inverter capacity when adding more panels to your system. 

Using microinverters, each of the new panels can convert its own current via microinverters; updating your existing system is more straightforward than before.

The addition of solar panels with micro-inverters may be done in batches, and you don’t need a second inverter to accomplish so.

Microinverters also provide several additional benefits over traditional inverters.

To make it worth your while, you must research the pros and cons of the various mounting options and ensure that your site is well-suited for a solar installation.

To what extent do you want to boost your performance before adding solar panels to your system?

Will you be able to handle the extra demand without sacrificing the efficiency of your current power source?

Is there enough space on your roof for a large array?

These are just some of the questions you’ll need to answer when choosing a mounting option for your solar panels.

We need to keep in mind that several things are putting solar panels on the roof.

For many homeowners, this is the most crucial aspect of their project. Solar panels can be attached in some ways.

Your energy bill might help you figure out how much more power you’ll need if you’ve raised your electricity use since you originally installed your solar.

Should You Consider More Panels on Your Solar System?

Increasing the number of solar panels on your roof may help mitigate the cost impact of your house extension.

In the last few weeks, a customer inquired about whether or not he should install solar panels on his new house expansion.

The answer is a qualified yes.

It depends, however, on several factors:

  • Your location.
  • What kinds (and how large) is the extension you are planning.
  • The time frame for completion.
  • The amount of money you have to spend.

Before we get into the details, let’s examine some of the key considerations:

Location

Because of the abundance of sunlight, you reside in, installing solar panels in your house is highly recommended.

Roof Panel

If your home extension is on a flat roof, then the cost of adding solar panels will be minimal.

However, if the extension is on a pitched roof, you will need to consider the impact this has on the cost of the system.

Energy Output

The amount of energy you can generate from your solar panels depends on the size of the panels and the amount of sunlight that hits the roof.

Cost

The cost of installing solar panels depends on the number and size of the panels you need and whether or not you have a ground mount system.

Ground mounts are less expensive than roof mounts but require some installation expertise.

They also provide a more significant amount of shade from the sun. The cost of roof mounts will vary depending on your roof type.

Furthermore, extensions often give extra roof space for installing a second solar array.

Permitting and Interconnection When Consider to Add Panels in 

Solar panels put on your property may need a thorough understanding of getting the necessary permissions and connections.

Check with your local utility provider first if you’re thinking about installing solar panels on your house.

They will be able to give you a complete list of what you need to do and what permits you will need to apply for.

Is it necessary to get extra permissions or submit additional interconnection papers to your utility provider to add more solar panels to your property?

The answer depends on whether you have a net-metering agreement with your utility provider. If you do have it at home, then your answer is yes. If you don’t, then the answer is no. For homeowners, if your utility provider has a net-metering agreement with your local power company, you must obtain a “net metering interconnection permit” from your utility provider before adding solar panels to your property.

Aside from that, your local area’s regulatory regulations, the number of extra panels you’re installing, and how many inverters you’ll need to purchase might all affect this.

To know for sure, you can find out if you need a permit by contacting your local building department.

If you need a permit, your local authorities will inform you what you need to do.

This includes where you should set up the inverter array.

You’ll also need to tell them whether you want to put the system on your property.

If you choose to put it on your property, you may need to install a transformer to run your inverter from an existing power source.

The quantity of space available will play a role when it comes to how many inverters you can fit in an array.

You’ll also have to determine how to connect each inverter to the power source.

The Takeaways

For various reasons, such as adding a new electric vehicle (EV) to your household or an inefficient solar panel system, your power consumption may have increased after installation.

Installing an additional solar panel system will be different from the process you went through while looking for a solar panel system first, and the things you need to be prepared for are what kind of batteries you should get and how much energy you want to store.

You also have to know what kind of solar panels you should buy, how to size the panels properly, and where you can put them.

You should also know the costs of installation and maintenance.

Incentives (such as tax credits and rebates) you were qualified for when you first installed your system may not apply if you’re adding more panels to your system. Many incentives may only be claimed once per property or once per individual.

You might be eligible for federal solar tax credits or incentives if you signed a loan or cash purchase agreement, though your refund is if you install more panels in certain places.

Determine whether or not more panels will affect your tax refund by visiting the state energy office website.
